-Prologue Chapter F-

o-0-o

A gentle, rhythmic vibration pulsed through his body, nudging his consciousness to life. Sparda's eyes slowly opened, greeted by the gentle caress of the soft, otherworldly dawn light that bathed his surroundings in an almost mystical glow. Blinking away sleep, he turned his head, still groggy, trying to make sense of his unfamiliar surroundings. Despite his growing awareness, a cloud of confusion lingered, entangling the threads of his memory.

"Where am I?" His thoughts reached back, recalling the intense battle with Chroma, the subsequent void that had swallowed them both, and the eventual sealing of the rift with Yamato. However, a missing piece in the puzzle remained; he couldn't remember creating an exit before losing consciousness. Unless something had occurred during his blackout that eluded him, perhaps this surreal experience was a creation of his own mind, a trick his senses were playing on him.

He forcefully dismissed the notion that he might have lost his sanity. The tangible reality of his surroundings couldn't be denied. The sensation of the cold metal walls against his head, and the lingering fatigue from exerting his demonic power were all too real, affirming that the recent battle with Chroma had indeed taken place.

He sighed, an unusual sign of restlessness for one of his caliber. Nevertheless, he understood that unraveling the mystery that held him captive was of utmost importance. He found himself confined within an extraordinary commuter train, a stark departure from the steam locomotives of the Human World that he was accustomed to. His gaze wandered, noticing the impeccable craftsmanship of the train's walls, almost dampening the vibrations of the train.

As he surveyed the interior, he couldn't help but notice the meticulously arranged seats on both sides and the high-tech billboards displaying dynamic advertisements, seamlessly fitting with the sleek, advanced aesthetic. The absence of the usual acrid scent of diesel or coal and the profound silence only deepened his bewilderment. The air felt pure and crystalline, slightly chilly but not uncomfortable.

Standing up, he attempted to pry open the nearest door but to no avail. "Okay...one more time," he muttered to himself, trying to tap into his demonic strength. However, his powers fizzled out, leaving him gasping for breath and on his knees.

"I suppose this is what it feels like for humans to grow old? Maybe it's karma for all those wrinkles jokes I made to Morrison," he mused, revealing a rare sense of restlessness. "Let's see if it can withstand the firepower of Luce and Ombra." Yet, as his hands reached for his back, he discovered that his hand-crafted guns were nowhere to be found. He chuckled at the audacity of whoever had thrust him into this situation and dared to take his prized guns.

"At least the views outside are pretty decent."

Turning his gaze to the windows, he hoped to gather clues about his current whereabouts. Frustratingly, the glass offered no insights. Still, he found himself captivated by the breathtaking panorama—an unchanging landscape, with tranquil, shallow waters reflecting a clear blue sky and stationary clouds, embellished with numerous vibrant blue rings. The white sandy beach glistened in the sunlight, creating an illusion of stars twinkling within the water.

"This is undoubtedly not the Human World," Sparda observed. The unusual rings in the sky confirmed his conclusion unless a profound transformation had occurred during his unconsciousness.

Staring at the rings, a glimmer of recognition stirred within Sparda's memory. "Where have I... ah," he suddenly recalled. The rings bore a striking resemblance to the halo above the head of the blue-haired girl he had seen in the void, at least in terms of their shape and color.

Reflecting on the events that had transpired within the void, he struggled to piece together the details of what the blue-haired girl had said before everything went dark. Numerous questions swirled in his mind. How had he ended up in this place? What had become of the girl? Could she be the cause of his current situation? If so, where was she now? Had he been the sole survivor?

And what in the world was Chroma? It was unlike anything he had encountered before. A demon? A devil? He doubted it was that simple. But there was little doubt that it had some connection to those 'Nameless Gods' the fanatical clergy kept mentioning.

Pinching his nose in frustration, he realized he had forgotten to determine the true nature of those Clergymen. However, since they could be dealt with just like how one dealt with any ordinary demons, he doubted that they, by themselves, posed a significant threat to the protectors of Vie de Marli or the Order's paladins if they decided to cause trouble in the Human World.

Numerous questions raced through Sparda's mind, and he understood that he couldn't find the answers on his own. He had two options: track down the clergy's associates or confront Chroma directly. The former seemed risky, as they appeared intent on killing him on sight. As for the latter, it also seemed unreasonable, as a battle would likely erupt the moment Chroma spotted him.

Another option was to locate the girl he had seen in the void. He had no idea how informed she was, but at this point, she was the only lead he had to unravel the mysteries plaguing his mind.

"No. Even if she doesn't have answers, I can't leave a young girl in a place like that," he declared. He didn't know her backstory or how she had ended up there, but he refused to abandon a child in such a situation.

And who knew, she might be trapped with Chroma inside and needed help right now.

Life was never straightforward, was it?

With a sigh, he made his decision. "Alright, let's go back and find her." Questions about her identity could wait; answers to his inquiries could come once she was safely out of that place.

If she didn't have answers for him, then it meant he had to consider the first or second option.

As Sparda prepared to summon Yamato, a soft giggle gently entered his ears, accompanied by a unique fragrance that tantalized his senses. Intrigued, he scanned his surroundings and noticed another passenger in the next car, someone who hadn't been there when he had initially examined the train's interior. Despite being partially concealed, a glimpse of white and red attire caught his eye. Without hesitation, Sparda moved to the next car, determined to confront the person, disregarding any potential traps.

With the press of a button, the door between them slid open, and Sparda, acting on instinct, advanced toward the other passenger, recognizing her as the young girl he had been thinking about.

"Sensei, I'm relieved to see you're safe," the young blue-haired girl expressed her relief upon seeing him. Her once-pristine white uniform was now marred by crimson stains, and she bore grievous wounds on her chest and abdomen, her breaths shallow and erratic.

"Don't speak," Sparda urged, swiftly tearing a sleeve from his shirt to fashion a makeshift bandage. "Who did this to you? Was it Chroma?" He sought answers, his concern evident.

The girl remained silent, offering only a faint smile amidst the occasional grimace of pain as Sparda applied the bandage. "You've always been like this," she noted, her tone a blend of fondness, admiration, and exasperation. "Even though you've cautioned me against rushing into trouble, you risk your life for others without hesitation. I think I understand now; this is the 'unfairness' of being an adult that you've talked about, Sensei."

Sparda shook his head with a sense of bemusement. "I can't recall ever having a student quite like you." His hands moved deftly to staunch her wounds and provide comfort. "Stay strong; you'll get through this."

Despite the pain she was enduring, the girl's smile broadened, but beneath it lay a profound sense of regret. "Everything was my fault," she confessed, her head hanging low, causing blood to trickle from her forehead onto her ankle-length hair. "My decisions and their consequences have brought us to this point. If only I had listened to you back then. Sensei... it took all this to make me realize that you were right all along. Please forgive my impudence, but I need your help." Her plea, filled with desperation, gave Sparda a momentary pause.

Looking up, Sparda finally saw just how young she was. She hadn't even reached adulthood, yet her blue eyes bore a weight he recognized all too well—a weight he had seen countless times over millennia.

She was a leader who had failed her kingdom and her people.

A young child thrust into a position of power before fully comprehending the implications and responsibilities that accompanied it.

A girl who believed she had taken the best possible course of action, trying to meet the lofty expectations others had placed on her shoulders, only to find herself falling with no one to catch her.

She was all of these things and more.

He had encountered individuals like her in the past, and though they were some of the most exceptional humans he had ever encountered, it was precisely their extraordinariness that caused them to crumble from within.

Their gazes locked in a silent exchange, and he released a sigh. "Today seems to be a day for cryptic conversations. Be it you, those fanatics who summoned Chroma, or the mysteries of this place, clarity seems to be elusive. But if you seek a mentor, I can spare some time to share my teachings with you. Only after your wounds have healed, though. How does a lesson on the art of demon-slaying sound for a start?"

His light-hearted words carried genuine warmth and understanding. In the face of danger and uncertainty, humor was a tool to lift one's spirit. He continued to tend to her injuries, providing both physical care and emotional support.

"If you meant what you said, you've already demonstrated great strength and resilience," he reassured gently. "Accepting responsibility for our actions, learning from our mistakes, and seeking assistance when necessary are signs of maturity. Not everyone possesses the courage to acknowledge their weaknesses and take steps to improve. And remember, we cannot foresee every outcome; we can only make the best decisions with the knowledge we have."

The girl managed a feeble nod, her smile persevering, though fainter. "Thank you, Sensei. Your words hold great meaning for me."

"I'm still puzzled; you speak to me as if we've known each other for a long time. And the way you addressed me... as I mentioned before, I have no recollection of ever having a student like you," Sparda mentioned, attempting to get some clarification.

The girl momentarily held her breath, exhaling with a sense of resignation. "It's okay, Sensei. Your confusion is only momentary," she assured.

"What do you mean?"

"In the end, you won't recall this conversation. You won't remember me... because 'I' won't be there with you. Not anymore."

"What do you mean by that?"

"It's precisely as I stated," the girl responded. The train gradually came to a stop. With the outside view engulfed in blinding light, Sparda couldn't discern where the train had stopped. "This is it, Sensei. I know that you'll face numerous trials and challenges in the near future, but regardless of what unfolds, I believe you and those you encounter will find a way to alter the grim future that awaits."

The doors slid open, bathing them in intense light. As Sparda squinted, shielding his eyes, he felt a powerful tug on his body, as if the light itself was trying to grab him or perhaps the train was attempting to eject him.

He looked back at the girl, and she gave him a small wave. The smile persisted on her face, but a solitary tear rolled down her cheek.

"Goodbye, Sensei. For the first and the last time, I'm grateful I could listen to your lesson."

Sparda fought against the pull with all his strength, cursing his present powerlessness. With an outstretched hand, he tried to reach for the girl, but it was a futile endeavor, and his resistance waned.

As he was drawn into the light, he yelled, "I won't forget you – no, even if I do, I'm certain 'I' will discover a way to remember you!"

The doors slammed shut, leaving the girl alone.

"That's not possible. You can't remember what hasn't transpired," the girl shook her head.

But... if a miracle could manifest, allowing them to meet again...

"Then... at that time... I'll—"

Nanagami Rin leaned against the window frame, her gaze fixed on the chaotic scene unfolding beyond the glass. The city had been gripped by this unsettling situation for days, and while labeling it as mere "turmoil" might seem exaggerated in the present moment, Rin could sense that genuine chaos was on the verge of erupting. They were perched atop a ticking time bomb, utterly powerless to handle, let alone disarm it.

Her long, cascading jet-black hair swayed as she paced within her office, a manifestation of her restless thoughts. Despite the composed facade she wore, her deep blue eyes revealed the strain she bore since the mysterious disappearance of the General Student Council president.

In her role as the Chief Administrator Officer and vice president of the General Student Council, Rin regretfully lacked the authority to access Sanctum Tower and restore control of Kivotos to the council. The city's infrastructure had ground to a halt because the only person with exclusive control over Sanctum Tower had vanished, leaving behind a note promising to send 'Sensei' to act on her behalf.

Rin had no knowledge of who this Sensei was or when they would arrive, and this uncertainty weighed heavily on her. If Sensei didn't arrive soon, the situation could spiral out of control, and unfortunately, the students would primarily hold the General Student Council responsible for any such situation.

For her personally, since she carried the burdensome mantle of 'Acting president,' she would have to face the music, whether she liked it or not. Bracing herself, Rin took a deep breath and decided to pay a visit to the president's office, a routine she had adopted since the president's disappearance.

The reason for continuing this ritual eluded her. Perhaps it was a coping mechanism to deal with the mounting stress, a faint hope that the president might miraculously reappear in her office as if nothing had happened, or maybe a wish that when she opened the door to the president's office, Sensei would be there to save the day. It might have been a blend of these thoughts or something entirely different.

With a myriad of pressing issues demanding resolution, Rin had no time for self-reflection to pinpoint the exact answer. Furthermore, she knew that the students who frequented the General Student Council Office to voice their complaints about the failing infrastructure wouldn't afford her a moment of solitude anyway.

With a heavy sigh that seemed to carry the weight of the world, she found herself standing at the imposing door to the president's office. It had become almost a ritual, a matter of routine, to knock on that door, even though she knew that it was unlikely to yield any response. Out of sheer habit, she raised her knuckles and gave a polite but somewhat resigned tap. "president, I'm going in," she announced, her voice tinged with the familiarity of her routine, fully aware that her words were more a formality than an expectation.

As she stood before the grand door, nerves coursing through her, a moment of astonishment washed over her as a voice, unexpectedly, emerged from within the room. "Come in," it said, breaking the silence that had become the norm.

In response, she promptly turned the doorknob and pushed the door ajar, revealing something entirely out of the ordinary. Before her stood a man, clad in a sleek leather coat with his back turned to her. His hair, slicked back and strikingly white, hinted at an aging countenance, but since she couldn't discern his face, she reserved the right to reserve her opinion. As he slowly turned to face her, Rin noted that he appeared to be only around a decade older than her, at most. His piercing blue eyes locked onto her deep blue ones, and for the first time in what felt like an eternity, Nanagami Rin allowed herself to feel a glimmer of hope.

This man had suddenly materialized in the president's office. In normal circumstances, she would have been deeply suspicious of a stranger's unannounced arrival, but desperation, it seemed, had led her to entertain the possibility of hope, even against her better judgment.

"You... Are you—" Rin started but hesitated, her voice catching in her throat. She took a deep breath and tried again, her words tentative. "Are you... Sensei?"

The man arched an eyebrow, his expression enigmatic and somewhat playful.

"Me? No, I'm not Sensei," he replied, his tone serious, leaving Rin's heart on the verge of sinking. But before she could fully process her disappointment, he continued, "My name's not Sensei; my name's Sparda," he added, almost teasingly.

It took a few moments for Rin to realize that the man before her was playfully toying with her, and her lips couldn't help but twitch into a hint of a scowl.

Pushing up her glasses, her hand moved instinctively to her Desert Eagle, poised to reprimand the man for daring to jest when she had so much on her plate.

The man, Sparda, seemingly sensing her readiness to take action, raised a placating hand. "Wait. Don't be hasty. I apologize. I couldn't resist trying to make you smile when I saw you enter with such a serious and somber expression."

"I'm not amused," Rin stated.

"I'm sorry," Sparda apologized.

"Answer me. Are you Sensei... Sparda-Sensei?" Rin inquired. The anticipation in the room grew palpable as she awaited his response.

"Depends on who is asking. Tell me… Are you 'Rin-chan'?" Sparda quipped with a mischievous glint in his eyes.

Rin coughed, taken aback, and a blush of embarrassment crept across her cheeks upon hearing the affectionate nickname bestowed upon her by the president.

"H-how did you–?!"

"Here. A letter… just for you and me," Sparda offered with a mysterious smile, presenting an elegantly sealed envelope addressed to 'Rin-chan and Sparda-Sensei.'

Snatching the envelope from Sparda's outstretched hand, Rin examined the elegant handwriting with a raised brow.

"No need to be rude," Sparda remarked.

Rin chose to disregard Sparda's comment, focusing instead on tearing open the letter.

"Dear Rin-chan and Sparda-Sensei," she read aloud, recognizing the distinctively elegant handwriting of the president. "This writing…it's truly the president's."

"I apologize for my abrupt departure, but rest assured, I have my reasons.

Rin-chan, I'll be entrusting the fate of Kivotos to you and Sparda-Sensei. I know that with the two of you at the helm, the city will be in capable hands.

Regrettably, I can't reveal more, but please trust that it's for your own good. Please don't worry about me; I assure you, I'll be fine.

And as for you, Sparda-Sensei, please keep a close eye on Rin-chan. She might appear cool and composed, but she's more sensitive than you think. When that happens, please shower her with your attention until her grumpiness dissipates."

Rin was on the verge of tearing the letter to shreds, but her self-restraint prevailed.

"I wish you both the very best, Rin-chan and Sparda-Sensei. I'm sorry I can't be there to assist you."

Rin let out a resigned sigh. The president's tendency to act without consultation or explanation frustrated her, but she couldn't deny that the president always had Kivotos' best interests at heart.

She fondly re-read the letter one last time; however, this time, a small footnote at the bottom of the letter caught her eye.

"P.S. Sparda-Sensei, I know you've had your fair share of experience with women, but if you plan to carry Rin-chan in your arms like you've done to so many others, be ready to shoulder the responsibility. Consequences will follow if you don't."

Rin scrutinized the last paragraph, ensuring she hadn't misread it.

"What does the letter say?" Sparda asked with curiosity,

Rin's shoulders tensed slightly. "It's nothing significant."

"Is that so? Then why are you taking a step back?" Sparda-Sensei inquired, taking a step closer.

"Please stay where you are, or I'll have to call security," Rin warned him, eyeing him like he was an enemy of all womenkind.

Sparda-Sensei stopped, baffled by her threat.

"Alright, alright. But what the devil is in that letter?"

Rin tossed the letter to Sparda-Sensei and retreated further.

Sparda-Sensei picked up the letter and quickly read its contents. Before long, his expression went dark. "What in damnation is this slander?"

"Are you denying it, then?" Rin asked.

"Well, I've had some interactions with women in the past, but those were—hey, don't point that gun at me. Hear me out first!"

And so, Nanagami Rin spent nearly an hour grilling their supposed 'Sensei' about his past dealings with women, resulting in a somewhat comical and awkward exchange of words, with an air of uncertainty and tension permeating the room. Sparda-Sensei, despite his initially slightly mischievous demeanor, found himself in the hot seat, defending his past actions as Rin probed and questioned him relentlessly.

Slouched comfortably on the plush sofa in the guest lounge, Sparda found himself already feeling mentally drained, even though only an hour had passed since he awoke. The clock on the wall indicated that the time was just slightly before noon, prompting a weary sigh to escape his lips. Why, he wondered, did he have to divulge his past experiences with women right after waking up?

The person questioning him, Rin-chan – although she had insisted he shouldn't use that moniker – had left him in the lounge. She mentioned something about informing others and making preparations. What these preparations entailed, he had no idea. At least Rin had been hospitable enough to serve him a steaming cup of tea before leaving, although her wary gaze remained fixed on him. It seemed like it might take a while to improve his image in Rin's eyes.

He supposed he should view it as a positive that he managed to clear up the misunderstanding with Rin before it spiraled out of control. The thought of the rumors that could have spread like wildfire if that issue wasn't promptly addressed made him shudder. Still, he felt a strong desire to meet this president face-to-face and express his displeasure about her easily misinterpreted statement.

Furthermore, entrusting the management of 'Kivotos', an entire city filled with students, to a complete stranger like him was bewildering. He was certain he had never crossed paths with this 'president' before, so why did she presume to burden him with such immense authority?

As he pondered this so-called president's intentions and her underlying motives, he also considered what had prompted her to make this drastic decision. More likely than not, there was more to this tale concealed in the shadows, waiting to be unraveled. Sparda recognized the need for answers, not only for his sake but for Rin and the people of Kivotos, who deserved transparency and certainty in their leadership.

But then, something struck him like a lightning bolt. "Wait a second," Sparda muttered, pushing a finger to his head. Why had he immediately assumed Kivotos was an academy city? He hadn't received any information from Rin, and the only time he'd ever heard the word 'Kivotos' was from the letter the president had left behind.

Rin's words jolted him from his reverie, as though she had cast a spell that summoned his attention back to the present moment. Her voice carried an undertone of urgency that was impossible to ignore, and she deftly redirected his focus toward her.

"Sensei," she uttered, her voice slightly apologetic, her gaze piercing through the distractions that had momentarily clouded Sparda's mind. "I'm deeply sorry for leaving you behind earlier, but now that you're here, we can finally address the matter that needs our immediate attention. It's a situation of utmost importance."

Sparda, his curiosity piqued, met Rin's intense gaze. "What kind of problem are we facing?" he inquired, only to find his gaze drawn to two additional individuals who had joined their ranks.

A playful, girlish voice interrupted his thoughts. "Hehe~, we've eagerly awaited your arrival, Sensei~. Greetings, I'm Momoka." The girl named Momoka had a youthful appearance, her short pink twin tails swaying with energy. Two barely noticeable small horns adorned her head, giving her an intriguing aura. She donned a stylish sleeveless uniform with a blue tie and a white leather jacket, but her most distinguishing feature was a black, scaly tail that gracefully emerged from her back.

"It's a pleasure to make your acquaintance, Sensei. My name is Ayumu. I'm sorry that we have to meet under these circumstances," Ayumu added, her tone weighted with apology as she offered a slight bow. She possessed long, straight, blonde hair and a pair of striking green eyes. A blue crystal adorned her forehead, and two black, feathery, angelic-looking wings extended gracefully from her lower back.

Rin stepped in to provide context. "Ayumu is my trusted secretary, and Momoka oversees the Transportation Office."

As Sparda observed their otherworldly traits, his eyes lingered on Rin's long, sharp ears and the halo that floated above her head. He then shifted his gaze to Ayumu and Momoka, noting the different shapes and hues of halos above their heads compared to each other. It finally dawned on him that Rin's ears bore a striking resemblance to those of elves from fantasy books, though he understood the complex reality that elves and angels were subspecies of demons, often misunderstood as distinct beings by humans.

Despite their unique characteristics, these girls were not demons, as Sparda had initially suspected. He couldn't detect the distinct scent demons emitted, nor sense any infernal energy emanating from them. In fact, if it weren't for these peculiar traits, he might have mistaken them for ordinary humans.

"Sensei?" Rin's voice gently called out to him, bringing him back from his contemplation.

Sparda shook his head, his expression thoughtful. "Ah, my apologies. Please, continue."

Rin nodded and beckoned for him to follow. "Sensei, please follow me. I will explain everything once we reach our destination."

In silence, they walked together, with Rin leading the way and Momoka and Ayumu following closely behind Sparda. They entered a bright, open room that seemed to double as a recreational space. Several girls, clad in uniforms similar to Rin's, Momoka's, and Ayumu's, chatted leisurely. Some had horns, some had bat-like wings, and a few had angelic wings similar to Ayumu's. Sparda even spotted one who appeared entirely human.

Yet all of them shared a common feature – each had a halo floating above their heads.

Moreover, Sparda noticed that every single one of them openly carried weapons, not just guns, but grenades, flashbangs, and even tear gas canisters. The sight was bewildering, and he couldn't help but wonder: had he stumbled upon a gathering of terrorists? It was almost surreal how casually these young girls treated these dangerous objects, as if they regarded them as mere accessories rather than weapons.

As these thoughts raced through his mind, he couldn't help but question what had happened to the Human World during his slumber.

The girls noticed Sparda's arrival, and an excited buzz of whispers rippled through their ranks, carrying with it a mix of curiosity and anticipation. He couldn't help but notice that they all referred to him as 'Sensei,' a title that left him perplexed and somewhat bewildered. He had no recollection of signing up for such a role, and he certainly hadn't made up his mind about accepting it.

As some of the girls appeared eager to approach him, they quickly retreated upon encountering the stern glare that Rin sent their way. It was a silent but clear message that seemed to say, "Keep your distance."

"Let's move on quickly, Sensei," Rin urged, her tone more of a command than a request.

Observing her stern demeanor, Sparda couldn't resist a quip. "Not very friendly, are you, Rin-chan?" he remarked casually, almost playfully. His comment elicited suppressed laughter from Momoka and Ayumu, who struggled to contain their amusement.

Rin's expression twitched, and the message her brief glare conveyed to Sparda was crystal clear: "Please don't call me that, or you'll regret it." Her disapproving look also had the effect of stifling the laughter of Momoka and Ayumu, who quickly composed themselves.

Sparda merely shrugged, showing he wasn't willing to spend too much energy on this particular disagreement.

For several minutes, they continued their silent journey, the anticipation and intrigue mounting with every step, until they finally arrived at a room that radiated an air of importance, a designated conference space for meetings. Rin approached the wall and, with a decisive press of a button, caused the curtains to ascend, unveiling the magnificent sight of Kivotos.

"Sensei," Rin conveyed with a sense of pride and enthusiasm, "let me formally welcome you to Academy City, Kivotos."

When the curtains gracefully rose, a breathtaking panorama unfolded before Sparda's eyes, leaving him momentarily speechless.

"Alright…this place is certainly not the Human World."

As he stood there, the enormity of the situation hit him like a tidal wave, and he couldn't help but acknowledge the profound differences between Kivotos and the world he once knew.

"Huh?" he muttered to himself, experiencing a strange sense of déjà vu that tugged at the corners of his memory.

However, Sparda pushed that aside and shifted his focus back to the city that sprawled before him. What he saw was a metropolis unlike any he had ever encountered. Towering skyscrapers seemed to defy the laws of physics as they reached for the heavens, showcasing designs more advanced than anything he had ever witnessed in the Human World. The technology in Kivotos was light-years ahead of his own realm, leaving him awestruck.

But what truly left him dumbfounded was the sheer scale of the city and its population. He had never seen a city so prosperous and bustling in the Human World; not even the supposed pinnacle of modern civilization in the Western continent could compare to what lay before his eyes.

As Sparda marveled at Kivotos, he couldn't help but wonder about its diverse inhabitants. Most of the individuals he observed appeared to be girls, all dressed in various uniforms. Among them, he noted humanoid animals and robots moving about with a remarkable sense of freedom, though curiously, none of these beings bore the distinctive halos that hovered above the girls' heads.

Sensing his bewilderment, Rin stepped in to provide some much-needed clarification. "Sensei, Kivotos is a city formed by a coalition of numerous schools, but six schools, in particular, hold significant influence due to their large student population and prestigious standing. However, the ones that require your closest attention are the 'big three.'"

"Big three?" Sparda inquired, now deeply intrigued.

"Trinity General School, Gehenna Academy, and Millennium Science School," Rin explained, providing him with the names of the institutions that held sway over this extraordinary city.

Sparda processed this information and sought further understanding. "So, the girls in uniforms are..."

Rin nodded in confirmation. "Yes, they are all students of Kivotos."

Curiosity fueled Sparda's next question. "Are you girls students here too?"

"We are! But we're a bit special, you see," Momoka chimed in, her voice brimming with pride as she answered Sparda's question. "We're the General Student Council!"

Sparda couldn't help but ponder their role. "Does that mean you wield authority over the entire city and all these schools?"

Momoka, her youthful exuberance undiminished, shook her head. "Well, not exactly. Each school holds its own authority, and sometimes they tend to overlook us. However, we serve as the central administrative body, responsible for managing a wide range of administrative tasks related to these academies, including the governance of the city in general."

"Interesting," Sparda mused, processing this new information. The revelation about Rin, Momoka, and Ayumu's roles as members of the General Student Council piqued his interest and curiosity, as it seemed to carry significant responsibilities within this unique city.

Sparda's gaze shifted to the sky, and as his eyes locked onto the blue rings adorning it, a rush of images surged through his mind like a tempest.

He saw a sky ablaze with those distinctive blue, glowing rings. It was a sight of a sky that felt both familiar and elusive. The recollection tugged at his consciousness, teasing him with fragments of a vision he couldn't quite grasp.

He found himself on a train, traversing through a desolate landscape. The feeling of solitude surrounded him. Was he truly alone, or was there someone with him? A person, a presence lingered in the depths of his memories, but their identity remained elusive, slipping through his grasp like sand through fingers. Flowing blue hair, or perhaps it was grey?

The blue rings dominated the sky in these visions, painting a canvas of perpetual daylight over a ship sinking into a vast black desert. He tried to recall the details, yet the recollection seemed tangled and distorted, refusing to align with the reality that he should have known.

"...sei!"

The sky morphed into a crimson hue, tainted with the metaphorical weight of blood. The girls were headed there, to the Ark, a place most forbidden and most venerated, where the burden of unfulfilled destinies coalesced.

"Sensei!"

The title echoed in his mind like a riddle. Why was he 'Sensei'? What had led him to this role, and what promise had he made? The questions swirled in his thoughts, elusive and haunting.

He glimpsed fleeting images of red and blue demons circling a withered tree, a juxtaposition of colors that seemed to symbolize duality—siblings, perhaps? Tears flowed from their eyes as a strand of gold hair breezed past him. Abandoned, left behind, repercussions of a pledge he had made, but to whom?

And what of the "Blue Archive", of the sacred oath he had sworn to uphold forevermore?

"SENSEI!"

Sparda snapped back to the present, his wide-eyed gaze shifting from Rin to the concerned expressions of Momoka and Ayumu. He felt a wave of confusion wash over him.

"I... what's wrong?" he questioned, attempting to comprehend the situation.

Rin, her voice laced with worry, explained, "Sensei, you've been in a trance for a good half an hour."

"Pardon?" Sparda was incredulous. He was certain he had merely been idly gazing at the unique rings in the sky.

"You were staring at the sky, and then you just... kept staring. I tried yelling at you to get your attention; I even slapped your face a few times, but you just kept... staring at the sky."

Sparda rubbed his cheeks, realizing the dull ache that had settled there. "Is that why my cheeks are hurting right now? Just how hard did you slap me?"

"Just enough," Rin replied cryptically.

"Just enough? What does that mean?" Sparda pressed, trying to piece together what had transpired.

Before further discussion could unfold, a new voice chimed in, drawing Sparda's attention.

"Hey, excuse me. I know I'm not an expert in the medical field, but don't you think you should take Sensei to see a doctor?" a new voice interjected.

Sparda's attention shifted to the newcomer, and he found himself face to face with four unfamiliar girls who had appeared on the scene. Each of them seemed to exude a unique presence and style.

"I can't say about the other academies, but Millennium has a pretty good medical center if you need a check-up. Oh, by the way, I'm Hayase Yuuka. Nice to meet you, Sensei," Yuuka introduced herself with a warm smile. She had long, flowing purple hair that reached down to her waist, held in playful pigtails adorned with a triangle-shaped device that resembled her halo. Her bright blue eyes sparkled with friendliness. Yuuka was dressed in a black and white blazer but added a touch of individuality with a white and blue hoodie, and an access badge. A tucked-in white shirt with a blue tie completed her ensemble, along with a black pleated skirt that featured a white belt adorned with attached bullet pouches.

Another girl chimed in confidently, her presence underscored by striking red eyes and large black angel wings on her back. "True, in the field of medical science, perhaps Millennium has us beaten. But, in terms of spiritual healing and physical treatments, there are a number of clubs in Trinity that are highly trained to provide both." She had long black hair and wore a stylish crop top, a long, parted skirt, black gloves, thigh-high stockings, and a black sailor dress with a red stripe accenting the pleated skirt and sleeves.

"It's a pleasure to meet you. I'm Hanekawa Hasumi," the second girl, Hasumi, introduced herself cordially.

"Gehenna Academy also has a... never mind. I think it's better if you visit Millennium or Trinity if you want to receive proper treatments," chimed in the girl with long silver hair, tied with black bows in twin tails.

Her bangs covered her left eye, and she had bright red eyes, a fair complexion, elven ears, and a black devil's tail. Her Gehenna Academy uniform showcased a white collared shirt with black and white striped cuffs, a black tie with two white chevrons pointing downwards, a gold pin on her left chest, and a red military armband around her left sleeve. The outfit was completed with a black corset, gold-buttoned short flowing skirt, knee-high black stockings, and black high-heeled boots.

"You are... Shiromi Iori-san of Gehenna's Prefect Team, right?" Hasumi inquired, her tone more of a statement than a question.

Iori, seeming surprised that her name was recognized outside of Gehenna, replied, "Oh? I didn't know my name was well-known outside of Gehenna. I thought only our Chairman had that kind of reputation."

Hasumi explained, "It is the duty of peacekeeping forces like our Justice Task Force to know of potential problems in Gehenna before they bare their fangs on Trinity." With a brilliant smile that seemed to invite confrontation, she continued, "Of course, we've also factored in the Prefect Team into the equation, including its hotheaded squad captain."

"Why you!" Iori bristled, ready to act, but Sparda intervened. "Get out of the way-oww!" Iori staggered backward, having received a flick on the forehead from Sparda.

"Cool your head," Sparda advised Iori before turning his attention to Hasumi. "You, too. Don't start a problem when you don't need to."

"Y-yes," Hasumi responded, now subdued.

The final newcomer, seemingly feeling obligated to diffuse the tension, stepped up next to Sparda, attempting to lighten the atmosphere. "S-surely it isn't that bad in Gehenna? I mean, Iori-san here hasn't started any problems yet," she said with an awkward laugh.

This bespectacled girl had a black bob cut and wore red glasses, a white butterfly hairpin with a red stud, and a speaker earpiece. Her elven ears and amber eyes gave her an endearing look. She sported a standard uniform with a navy blue blazer and an access badge, similar to Yuuka's but with a different logo. Her outfit included cuffed sleeves, a beige sweater, a tucked-in white shirt, a cyan tie, and a pleated, plaid black skirt. A cyan armband with dark stripes completed her ensemble.

"At least there's one reasonable person among us," Sparda remarked, acknowledging her attempt to ease the situation. "Your name?"

"Oh, i-it's Ayane. Okusora Ayane from Abydos High School," the bespectacled girl, Ayane, stammered nervously.

Sparda gave a polite nod, a hint of warmth in his eyes as he extended a slight smile. "I'm Sparda. It's truly a pleasure to make your acquaintance," he said. The tension that had previously gripped the room seemed to dissipate, replaced by a palpable air of cautious curiosity.

"Hmm…"

Yuuka, however, had a different agenda. With measured steps, she closed the gap between herself and Sparda, her gaze focused on him with an intensity that suggested she was trying to unravel the very essence of his being.

"Now what?" Sparda couldn't fathom what she intended to find with such an intense gaze, but he couldn't resist teasing her. ""What's caught your eye, I wonder? My face may be a masterpiece, but even I can blush under such a penetrating gaze," he quipped, his words dripping with playful allure.

Understanding the implication of his comment, Yuuka took a step back, her face now a rosy shade of embarrassment. "Wha-! No! It's not like that! Stupid!" she retorted, casting her gaze aside in exasperation.

"Heh." Sparda couldn't help but find her reaction endearing. "What a cute reaction," he thought, a hint of amusement in his eyes.

Amidst this unfolding interaction, Rin, always the pragmatic one, took charge by clapping her hands, effectively silencing the group. "Alright, that's enough. Let's put the idle chit-chat to rest. If there's nothing else to discuss, we should transition to a more pressing matter," she declared, though her stern tone couldn't completely mask the underlying concern that lingered in her eyes.

Rin directed her attention to Sparda, her voice brimming with genuine worry. "Sensei, if you're not feeling well, we can delay the matter we discussed earlier until you're in better condition."

"The matter of utmost urgency?" Sparda sought to clarify.

"Yes," Rin affirmed.

"I'm perfectly fine. We can proceed with whatever you require," Sparda assured her.

Rin attempted to voice her concerns once more, but Sparda firmly reassured her, his words leaving no room for doubt. "Trust me, I'm in good shape."

Although Rin appeared unconvinced, she yielded. "Very well. In that case," she shifted her focus to the four newcomers, her expression serious, "may the annoyances please leave? We are about to start a very important operation."

Iori, refusing to let the slight pass, voiced her indignation, "Who do you call annoyances?! We're here to find out what's going on because you haven't been doing your jobs to resolve this situation!"

Hasumi joined the chorus of disagreement, stating, "While it pains me to agree with someone from Gehenna, I have to concur with Iori. At the very least, we deserve an explanation and the status of the situation."

Yuuka, clearly irritated, added, "Where is that president anyway? Shouldn't she be solving these problems by now?"

Rin, despite appearing to lose patience, explained, "The president is currently away, but she entrusted the management of Sanctum Tower to Sensei before her departure."

"Sensei is?" Ayane inquired, her gaze seeking confirmation from Rin.

Rin nodded in confirmation. "Indeed. The president explicitly informed me that she would be entrusting the control of Sanctum Tower to Sensei before her departure."

Sparda suddenly felt the weight of all eyes upon him, but it was Ayane, the bespectacled and polite young woman, who appeared most invested in his newfound status.

"Does this mean Sensei will have authority over all of Kivotos?" Yuuka mused to herself, a realization dawning in her voice.

"Which is why... may I kindly request all the nuisances to exit the premises? This is an issue for the General Student Council to handle," Rin declared with urgency, her words cutting through the murmur of voices. "It is imperative that we—"

"U-umm..."

"You just don't want to deal with us, do you?!" Iori accused, her frustration palpable.

Sparda could see Rin's restraint slipping, though she managed to maintain her composure. If he had to guess, Rin truly didn't appreciate dealing with people who incessantly interrupted her. "...Not exactly, it's just..." She adjusted her glasses, her tone growing blunter. "Why spend time with the loudmouths when there are far more productive endeavors to be done?"

"Quite blunt, aren't you?" Hasumi commented, beads of sweat forming on her brow.

"Isn't this just how she is? The cold and unfeeling vice president of the General Student Council, the world will face an apocalypse before she shows any warmth," Yuuka remarked.

"Oh? I'd argue that your reputation isn't spotless either, Miss Treasurer of Seminar," Rin shot back plainly.

Yuuka was momentarily taken aback. "T-that's only because someone had to—"

Rin's interruption was like a swift and efficient gust of wind, cutting through the room's atmosphere. It was evident that she had no patience left for any nonsense from these girls.

"Momoka, has the transport been prepared?" Rin inquired, her tone laced with authority and urgency.

Momoka responded promptly, "Absolutely! We just need to make our way to SCHALE to retrieve the city ba—"

"Excuse me!"

Ayumu's voice pierced the room, every gaze now zeroed in on her.

"Umm... I don't think it's wise to fly there," Ayumu hesitated, her voice quivered. "I received a call... they mentioned that delinquents led by the Fox of Calamity have taken control of the building. It would be impossible to land unless we first deal with them."

The atmosphere in the room turned grim as everyone except Sparda absorbed this revelation.

"The Fox of Calamity?! How in the world did she escape from the Federal Corrections Bureau's cells?" Iori's voice was laden with shock and concern.

"It seems she seized the opportunity amidst the chaos resulting from the system's breakdown to break free," Ayumu explained.

The news of the Fox of Calamity's escape and involvement injected an added layer of complexity into the situation. Each person present seemed to grasp the gravity of the threat, and Rin's response was chillingly pragmatic.

"Tch," Rin clicked her tongue in annoyance and then turned her attention to the representatives from Millennium, Trinity, Gehenna, and Abydos, her demeanor shifting from stoic to authoritative as she offered a disarming smile.

"Congratulations, dear representatives from our esteemed academies, you now have the opportunity to make yourselves truly useful. Given our shared desire for normalcy to return, why don't we all put forth our utmost efforts to regain control of SCHALE tower?"

Sparda couldn't help but raise an eyebrow at Rin's seamless transition from stoicism to command. It was evident that, in her eyes, there was no room for negotiation; this was an order, not a request.

"Y-you-!" Yuuka spluttered in disbelief at Rin's sudden change of heart, having just moments ago attempted to oust them.

"Fox of Calamity, huh? That moniker might just suit you better than her," Hasumi stated, earning a glare from Rin.

"I didn't come here to get into a gunfight with criminals!" Yuuka protested.

Rin advanced menacingly, leaving no room for argument. "Oh? How unfortunate. If the prestigious Treasurer of Millennium declines to assist Kivotos in its hour of need, I wonder how that might affect Seminar's reputation."

"That's blackmail!" Yuuka accused.

"I'm merely speculating, much like how you Millennium girls like to do," Rin responded simply.

Sparda anticipated a heated argument to start between Yuuka and Rin, but to his surprise, Ayane stepped up in his stead, acting as a mediator of sort. "Yuuka-san, since it can't hurt to help, why don't we pitch in? Who knows, our efforts might earn us future favor with the General Student Council." Ayane's subtle glance in Sparda's direction didn't go unnoticed. She clearly wanted something from him.

After a moment of contemplation, Yuuka sighed. "Fine, I'll do it," she reluctantly agreed.

"Excellent. Now, let us set out immediately," Rin ordered, her tone unwavering.

"I haven't agreed to help yet," Iori interjected.

Sparda couldn't believe the turn of events. He was still processing the resolution of one conflict when another arose. He couldn't fathom how Iori failed to read the room.

Sparda stared at Rin, who wore an inscrutable expression. Was she angry? Upset? He didn't dare speculate, but he knew Iori was pretty much screwed.

"Shiromi Iori-san, I seem to recall that someone else was supposed to be here. Our security protocols clearly state that only authorized individuals may enter the General Student Council buildings, and as far as I know, you haven't been granted clearance," Rin pointed out, her voice dripping with authority. "Unless you want me to report your trespassing to you-know-who, I would strongly advise you to comply for now."

"There's a reason for this!" Iori protested, attempting to explain herself.

Rin shook her head. "Oh? So the enforcer of the law is breaking the rules? How unfortunate. Why don't you put on a helmet and join those gangs instead? Who knows, with your temperament, you might find that being a rulebreaker suits you perfectly," Rin suggested with a disarming smile, which Sparda recognized as the most insincere smile he had ever seen.

"Iori," Hasumi intervened, placing a calming hand on Iori's shoulder before she could protest further. "It's wiser to yield. You won't win an argument with her."

Iori looked at Hasumi as if she had grown another head, but realizing that everyone was imploring her not to escalate the situation, she deflated.

Gritting her teeth, Iori directed an angry glare at Rin. "I won't forget this."

Rin paid no heed to the threat and turned her attention to Hasumi. "And what about you? Miss Vice Chairwoman of the Justice Task Force?"

"Of course, I'll assist. Left unchecked, the Fox of Calamity might turn her attention toward Trinity sooner or later," Hasumi affirmed, though a lingering tension remained between her and Rin.

Sparda, feeling like an outsider in this intricate web of student politics, couldn't help but offer a silent observation.

"Is this a gathering of students or politicians?"

Rin huffed, her expression softening slightly, though her aura still exuded authority. "If there's no further interference, let's depart immediately. The combatants will work to reclaim the building from the delinquents on the ground, while Sensei and I will provide aerial support."

With the theatrical exchange now concluded, Sparda felt compelled to express his disagreement. "I object," he declared, taking Rin by surprise.

"Sensei?" Rin raised an eyebrow, clearly taken aback by Sparda's unexpected stance.

"I'll take the ground route," Sparda decided, causing a ripple of concern among those present.

"What are you saying? The path there is filled with delinquents and gangs! Even if you're well-armed, it'll still be dangerous for you! This isn't like taking a leisurely stroll in the park!" Yuuka exclaimed, bewildered by Sparda's decision, her voice laced with genuine worry.

Sparda gazed steadily at Yuuka and retorted, "And it's not dangerous for you?"

"We have our halos, you don't," was Yuuka's straightforward response.

Sparda's silence lingered in the air, his gaze inadvertently falling upon the girls' halos. The casual way they wielded their weapons and incendiaries indicated a seeming lack of concern for the potential harm or even death that these tools could cause. Sparda had initially assumed it was due to their youthful naivety, but Yuuka's words made him reconsider.

They possessed halos, whereas he did not. The absence of a halo meant that confronting armed delinquents outside would be perilous for him. In contrast, it wouldn't be as dangerous for them because they had their halos.

Sparda deduced that the halos must be providing them with some form of protection, substantial enough to ensure their survival in a gunfight. He couldn't help but furrow his brow, struggling to make sense of this newfound information

Sparda pinched the bridge of his nose, grappling with the absurdity of the situation he found himself in. Nevertheless, he resolved to uncover more about this mystery later.

But he remained resolute in his decision. "I'm still going on the ground," he reiterated.

"Sensei, you're being unreasonable," Rin stated, her tone a mix of concern and frustration.

"Perhaps," Sparda conceded with a hint of amusement, "But if I'm going to be a teacher in this city, it's imperative that I get to know the students, whoever they are. Either you grant this one wish of mine, or... I'll leave," he declared, casting a bold ultimatum that left Rin taken aback.

Rin seemed surprised by his words, her typically unflappable demeanor momentarily shaken. Clearly, she didn't expect that he would put his position as a bargaining chip like this, an unexpected twist for her it seemed.

"You're being unfair," Rin responded, weighing her options.

"What can I say; adults are unfair," Sparda quipped, undeterred.

Very reluctantly, Rin relented, "Very well. But, you must, under no circumstances, go to the front line," she stipulated, her concern for his safety evident in her eyes.

Rin then turned to Ayane, addressing her directly. "Okuzora Ayane."

Ayane blinked in surprise. "Yes?"

"You are to stay in the rear and keep Sensei safe," Rin instructed, entrusting her with a critical role

"Eh? S-sure, I can do that, but aren't there more capable individuals here?" Ayane questioned, displaying her humility.

"We need them at the forefront. And besides, Sensei seems to have taken a liking to you," Rin noted.

"I-I see?" Ayane responded, a touch flustered.

Sparda, feeling the need to set the records straight, leaned in and humorously whispered, "Actually, I prefer a more mature woman."

Sparda felt the sting of Rin's boot on his foot as she silenced him, her tone menacing. "Did you say something, Sensei?"

Quickly, Sparda backtracked. "Nothing."

Rin wasted no more time. "Alright, no more dilly-dallying. Everyone, please do your best," she urged, rallying the troops with a stern yet supportive tone.

Everyone looked back at Sparda with trepidation, still questioning his decision, but Sparda only gave them a shrug, his casual demeanor at odds with the gravity of the situation.

"You heard her. Now, go on, I'll follow you from behind," Sparda said, reassuring them with a calm and determined presence.

They all seemed resigned to the fact that he wouldn't change his stance, and as they reluctantly stepped out to begin the operation, Yuuka couldn't help but voice her concern to Rin one last time.

"Is this really okay? Putting Sensei in danger like this?" Yuuka asked, a lingering worry etched on her face.

Rin sighed. "...Sensei insisted on this. The only thing we can do is to ensure he's not in harm's way," she replied, her shoulders carrying the weight of the responsibility.

Yuuka seemed unsatisfied with the answer she received but didn't press the matter further. Right as she was about to leave the room, she glanced back at Sparda, to which he simply waved at her casually.

Sparda thought of the girls with a slight hint of amusement. He never thought he would be in a position of being protected; usually, he was the one doing the protecting. Not that he planned to be just a bystander, though. He wouldn't let those girls do all the hard work.

Rin approached him, carrying a strange rectangular item in her hand. "Sensei, here. This is for you."

Sparda took the item and eyed it strangely "What's this?"

"A smartphone. You'll need it to communicate with the girls. All you need to do is tell the girls to activate the wireless sharing in their phones to establish a connection to yours and you should be able to communicate with them," Rin explained.

"…Okay?" Sparda honestly didn't get any of that.

Rin stared at him, incredulity in her eyes as realization dawned upon her. "You don't understand how to use it, do you?" she asked, her tone a mix of disbelief and exasperation.

Sparda, rather than trying to save face, decided to be honest. "I know it's a phone."

Sparda heard the loudest sigh he had ever heard from Rin slipped out of her mouth. "Did you live in a cave or under some faraway rocks?" Rin asked, exasperated. "Nevermind, please don't answer it. I don't want to know," Rin said, almost pleading.

Rin turned to Ayane, and asked her, "Ayane-san, I have to assume command of the operation, please guide Sensei on how to use his smartphone."

"E-eeeh?!" Ayane seemed exasperated that Rin had suddenly thrown the problem onto her lap, her face a mix of surprise and reluctance.

Rin, seemingly not wanting to deal with any more headaches, briskly walked away, leaving Sparda alone with Ayane, the responsibility thrust upon her shoulders.

Sparda turned to Ayane, offering a handshake. "Well…I'll be in your care."

o-0-o

Rin cast a scrutinizing gaze upon the bustling street below, perched in solitude within the aircraft's passenger seat. Typically, Ayumu, her faithful secretary, accompanied her on such missions due to her official role, but this time, Rin had opted for Ayumu to stay behind within the General Student Council, just in case any more unruly students decided to make an appearance.

The hushed serenity enveloped her for a brief moment, affording Rin a chance to reflect on the myriad enigmas that had recently engulfed her life. From the inexplicable vanishing act of the president to the sudden arrival of Sparda-Sensei, his peculiar behavior when he peered at the heavens, and his unwavering determination to join the impending assault force – these events had left her utterly bewildered.

Initially, Rin had believed that Sparda-Sensei bore the mark of a reasonable person, but it was an undeniable truth that one should never judge a book by its cover. He was proving to be every bit as eccentric and resolute as the missing president herself.

Just as she allowed her thoughts to roam, her phone buzzed, and Rin swiftly answered it, her voice carrying a sense of urgency. "Yes, Sensei?"

A sigh of relief resonated from the other end, presumably belonging to Ayane. "Oh, good, I managed to connect with you," Sparda-Sensei announced, his tone tinged with a hint of pride.

Rin couldn't help but respond with a touch of dry humor. "Congratulations, it appears Ayane-san has imparted the basics of modern life onto you."

Sparda-Sensei, unfazed by her sarcasm, inquired, "You don't sound too pleased, Rin?"

Her frustration mounted at his observation. "It's not personal, Sensei. My concern lies with the gravity of our situation. We're about to confront the delinquents led by the Fox of Calamity, and your decision to be on the ground introduces an additional layer of uncertainty. I hope you understand the inherent risks."

With a composed demeanor, Sparda-Sensei assured her, "I do, Rin. I acknowledge the dangers, but this mission also presents an opportunity for me to understand the students better. To be an effective teacher in this city, I must familiarize myself with the world they inhabit."

Rin sighed, detecting the sincerity in his words. "I grasp your perspective, Sensei, but please remember that our primary objective is the mission's success. If you become incapacitated, it will be impossible to fulfill that mission. So, please, if things become too perilous, you must retreat immediately."

Sparda-Sensei emitted a faint chuckle. "I'm not one to recklessly rush into danger, Rin. Don't worry overly."

Rin hesitated for a moment before expressing her concern. "Just... promise me you'll exercise caution, Sensei."

"I promise."

"Is that all?"

Sparda-Sensei shifted the conversation, saying, "Actually, I need you to brief me on what's actually transpiring. I'm rather clueless about what I should be doing here."

"Fufu."

"You laughed! You definitely laughed, didn't you?"

Rin chuckled, "Why do you seem so delighted by my laughter?"

Sparda-Sensei explained himself, "Rin-chan, let me bestow upon you a piece of wisdom – when a beauty laughs, the world becomes brighter."

"I might just put you in jail."

Apologetically, he said, "I'm sorry, it was an impulsive moment. I'm simply delighted to hear you laugh for the first time."

"I was laughing at myself," Rin clarified. "Forgive me, Sensei, I had momentarily forgotten that amidst all the chaos."

"I understand. If I were in your shoes, I might have forgotten too."

Rin heaved a sigh, pondering where to begin. After a moment of contemplation, she chose to delve into the matter of the Independent Federal Investigation Club, SCHALE, considering their mission was to restore its supposed headquarters back into Sensei's hand.

She conveyed to Sparda-Sensei that the president had created SCHALE as an extrajudicial, independent organization with a concealed mission, only comprehended by the president herself. Her understanding was limited to SCHALE being under the guidance of Sparda-Sensei, responsible for aiding every school and supporting students in various personal matters. Additionally, SCHALE possessed unrestricted access to and influence over students from all schools and held an equal level of authority as the president, establishing it as the foremost power in Kivotos apart from the president.

Sparda-Sensei summarized, "So, SCHALE is an organization with significant power, and the president entrusted it to me."

Rin nodded affirmatively. "Yes, that's the crux of it. The specifics of its operations and the extent of its authority have always been veiled in secrecy. We're not even certain of its objectives. But the president had faith in you, Sensei, which is why she appointed you as its head."

"I see. It's a weighty responsibility, and I lack substantial information about the city and its current state. What about the Fox of Calamity? How did she come into the picture?"

A dark cloud seemed to descend upon Rin's expression as she continued, "The Fox of Calamity is a formidable figure, a notorious criminal who had been incarcerated in the Federal Corrections Bureau's cells. It is unclear how she managed to escape or what her motives are, but she is one that must not be underestimated. Do exercise caution when you're in her presence, and while it is best if we could also apprehend her, please remember that our mission is to reclaim the building and prevent the situation from escalating further."

The line fell silent, save for the distant echoes of gunfire. Abruptly, Sparda-Sensei inquired, his tone gravely serious, "I have a question, Rin."

Rin's spine stiffened as she replied, "Yes?"

"What about the other teachers? I'm struggling to fathom why I, of all people, have been bestowed with this level of authority. There must be more qualified teachers who are well-versed in such matters."

Rin drew a deep breath, knowing that Sparda-Sensei might not react well to the revelation. "Sensei... you are the sole teacher in Kivotos."

An unbearable silence hung between them, feeling like an eternity.

"You're joking," Sparda-Sensei commented, his disbelief palpable.

Rin, undeterred by his incredulity, reaffirmed the stark truth. "Believe me – I'm not."

"Then, how were the lessons conducted?"

"Students either learned through instructional videos or participated in virtual classes. On rare occasions, we had guest lecturers from outside the city, but even those instances were infrequent."

Sparda-Sensei sighed. "So many questions, but I suppose they'll have to wait until we resolve this mess. Is there anything else you need to inform me about?"

"Once you've successfully secured the building, please await my arrival. There is an item known as the Shittim Chest stored within SCHALE – it's something the president instructed me to give to you."

"That makes it five, doesn't it?"

"Five?"

"Things that your so-called president entrusted to me."

"Why five?"

Rin could hear Sparda-Sensei's exasperated sigh from the other end of the line. "There's Kivotos, the students, SCHALE, the Shittim Chest..." Sparda-Sensei enumerated. "But I believe the first one is the most important, at least from your president's perspective."

"Kivotos, you mean? And that's only four, Sensei."

"No, the first thing she entrusted to me, and me alone, was you, Rin. She tasked me with looking after you."

"That's—"

"Didn't the letter mention it? If you're dissatisfied, you can debate it with your president when she returns."

Rin had no retort. Indeed, the president had entrusted Sparda-Sensei with the duty of watching over her in her stead.

"It appears Ayane needs assistance. I must go."

"Best of luck, Sensei."

"Rin, I understand that my role as Sensei was a decision made by the president, and you strike me as someone who respects and follows the decisions of those you trust. But I want you to keep one thing in mind."

"What is it?"

"Why did she choose me? That's all."

Sparda-Sensei concluded the call, leaving Rin to ponder the cryptic words he had left in his wake.

"Why you, indeed."

o-0-o

Ayane found herself thrust into a situation teetering on the edge of unpredictability when Sparda-Sensei insisted on participating in the ground offensive. The very notion of him, devoid of a protective halo, stepping into the battlefield sent shivers down her spine. Sparda-Sensei's nonchalant attitude towards what should have been a perilous mission for him only added to her mounting anxiety. Still, Ayane clung to the belief that Sparda-Sensei's rationality would prevail, offering her some comfort amidst the turmoil. Little did she know how drastically her expectations would be shattered.

"Sparda-Sensei! What on earth are you thinking? Please, take cover!" Ayane implored, her initial faith in Sensei's reasonableness rapidly eroding. To her utter dismay, Sparda-Sensei merely waved a dismissive hand in response to her frantic plea. Against all logical reasoning, he marched confidently towards the dangerous group of masked delinquents.

"Ladies."

"What?! Who's this old man?"

"Old man?" Sparda-Sensei appeared momentarily taken aback by the 'old' moniker, and in all fairness, his silvered hair could give him an elderly appearance from behind. Clearing his throat, he regained his composure. "Ahem. Starting today, I've been appointed as your Sensei. While the vigor of youth is commendable, might you consider channeling it through less... turbulent means?"

Ayane wanted to scream at Sparda-Sensei. If it were as simple as talking these delinquents out of their disruptive path, someone would have accomplished it long ago. Regrettably, her apprehensions proved justified as the masked troublemakers began menacing Sensei.

"Why don't you beat it, old man? With the city in turmoil, this is our golden opportunity!"

Sparda-Sensei remained unruffled, locking his intense blue gaze onto the leader, who seemed unnerved by the Sensei's unwavering eye contact. Chaos reigned in the city, and desperation had driven these youngsters to commit acts of violence. Ayane couldn't help but ponder how Sensei intended to navigate this treacherous terrain.

"Listen closely," Sparda-Sensei intoned, his voice resonating with unwavering authority. "I recognize that life can be tough, and your frustrations are valid. But there are better ways to make a lasting impact. You can choose to contribute to the problem, or you can be a beacon of solution. I'm here to steer you towards the latter path."

The delinquents exchanged furtive glances. They were undoubtedly unaccustomed to encountering someone like Sparda-Sensei—a man whose strength and wisdom transcended his physical presence. In Ayane's heart, a flicker of hope ignited; perhaps, just perhaps, they could be persuaded to amend their ways.

However, the delinquent leader remained obstinate. "Your words sound grand, old man, but they won't save this city. We're taking what we deserve!"

With that declaration, she lunged at Sparda-Sensei, catapulting the situation into a full-blown and potentially explosive confrontation.

Ayane desperately tried to close the distance between herself and the unfolding confrontation, her heart pounding with the realization that she'd likely arrive too late to make any difference. Her mind screamed at her to warn Sparda-Sensei to flee, but her voice fell silent as she witnessed a truly peculiar sight: Sparda-Sensei was beaming with an enigmatic smile.

"So, you're in the mood for a dance, are you? Very well, I shall introduce you to the exquisite art of classical ballet."

In a breathtaking display of agility and finesse, Sparda-Sensei swiftly disarmed the delinquent leader, and within the blink of an eye, he transformed what might have been a perilous confrontation into a mesmerizing spectacle. Their movements blurred into a dazzling fusion of combat and artistry. The leader, initially brimming with the expectation of a swift victory, found herself taken aback by the surreal turn of events. Sparda-Sensei's actions resembled a carefully choreographed performance rather than a gritty street brawl.

Spectators gathered in wide-eyed amazement as the sensei gracefully guided the bewildered delinquent through a series of elegant steps and spins, all while keeping her disarmed and off balance. It was an extraordinary sight, and the chaotic street seemed to hold its breath as people began to grasp that they were witnessing something far beyond the ordinary.

Sparda-Sensei's decision to transmute this confrontation into a dance had a profound effect. The delinquent, initially motivated by anger and greed, found herself entranced by the artistry of the battle. With each graceful movement, she became increasingly absorbed in the elegance of their interaction. It was as if Sparda-Sensei was teaching her a lesson through the medium of combat, revealing better ways to channel her fervor and vitality.

As the unique dance unfolded, the delinquent leader's expression evolved from one of aggression to one of deep contemplation. She began to comprehend the emptiness of her actions and the destructive nature of her chosen path. What she had expected to be a brawl was instead an unexpected lesson in life.

As Sparda-Sensei concluded the mesmerizing dance, gracefully guiding the once-aggressive delinquent into a respectful bow, the street erupted in applause and jubilation. The palpable tension that had gripped the onlookers earlier seemed to evaporate into the warm evening air. The delinquent, who had been completely consumed by greed and violence just moments ago, now displayed an expression marked by humility and deep self-reflection.

Astonished, Ayane finally reached the scene, bearing witness to the astonishing turn of events before her very eyes. "T-that was amazing!" she heard one of the masked delinquents exclaim, a sentiment echoed by others within the group who were coming to terms with the profound impact of the impromptu lesson they had just witnessed.

Sparda-Sensei's countenance beamed with satisfaction, his piercing blue eyes gleaming. "You possess a great talent as a dancer. Once this ordeal is behind us, if you have any inclination to pursue further dance education, why not consider starting a dance club? I will lend my support, and I'm certain your friends here will too. Isn't that right?"

"I-I'm..."

"He's right, leader! Your dance was beautiful!"

Sparda-Sensei's unconventional proposal stirred something profound within the delinquent leader. She gazed at her comrades, who had transitioned from troublemakers to an audience brimming with admiration and respect. The epiphany struck her like a bolt of lightning; she held a unique talent that could be harnessed for something positive.

"I... I've never considered it like this," she stammered. "Maybe... perhaps a dance club is a good idea."

Her fellow masked delinquents eagerly concurred, their faces alight with the prospect of a new, more constructive path. The stifling atmosphere that had once hung over the street had undergone a remarkable transformation, evolving into one of hope and inspiration.

Sparda-Sensei shifted his attention to Ayane, his smile growing wider. "You see, Ayane, sometimes all it takes is a change in perspective and a guiding hand to alter someone's life. These young individuals possess untapped potential, and all they needed was a gentle push in the right direction."

Ayane nodded in profound amazement, understanding that Sparda-Sensei's unorthodox teaching methods had not only disarmed the delinquents but had also disarmed their hearts and minds. On that chaotic street, violence and disorder had yielded to the beauty of self-expression and unity, and Ayane couldn't help but be captivated by the transformative power of a well-choreographed dance.

"Maybe... just maybe, if it's Sparda-Sensei," Ayane thought with a glimmer of hope, "he could help us." Her faith in Sparda-Sensei's unique ability to guide and inspire had taken root, and she couldn't help but cling to the possibility that he could be the catalyst for positive change in their lives.

o-0-o

Yuuka had been drawn to the commotion emanating from the direction where Ayane and Sparda-Sensei were meant to be. As she turned to see what was causing the stir, she found herself utterly bewildered. Sparda-Sensei and Ayane were turning around the intersection, completely encircled by masked delinquents. What was even more perplexing was the cheerful and congenial manner in which they interacted, with even Ayane herself laughing and appearing to thoroughly enjoy her time.

Yuuka, Hasumi, and Iori exchanged puzzled glances as Sparda-Sensei and Ayane approached them, conversing amiably with the masked delinquents now standing behind them. The entire situation felt surreal, and they couldn't fathom how such an abrupt transformation had taken place.

"What happened? Why are Sensei and Ayane with..." Yuuka began, her voice thick with confusion, but Hasumi chimed in to complete her sentence in an equally mystified tone.

"Oh, Yuuka, Hasumi, Iori!" Sparda called out cheerfully.

"Sorry we're late!" Ayane added, her laughter and smile still evident.

"Umm…Sensei, what's the deal with them?" Iori questioned with a hint of suspicion, her gaze fixed on the group of delinquents standing idly behind Sparda-Sensei and Ayane.

Sparda-Sensei, seemingly unperturbed by the bizarre scenario, cheerfully introduced the masked delinquents, "Oh, these girls? Well, we were discussing starting a dance club for them, and when I told them that we need to reclaim the building, they offered their help."

The explanation only deepened the perplexity that gripped Yuuka, Hasumi, and Iori. The masked delinquents, who had recently been their adversaries in a tense standoff, now seemed enthusiastic about assisting Sparda-Sensei and Ayane. They nodded and smiled as if they had known each other for ages, with no trace of the animosity that had characterized their earlier interactions.

Yuuka couldn't suppress her curiosity any longer. "I don't understand how they suddenly turned around and offered their help when just a while ago, we were in a confrontation with these girls."

Sparda-Sensei chuckled and placed a reassuring hand on Yuuka's shoulder, his eyes brimming with wisdom. "Sometimes, young ones, it takes a change in perspective and a shared purpose to unite people. These girls possessed untapped potential and were adrift in the city's chaos. We showed them a new path, one that's creative and positive. We offered them an opportunity to channel their talents in a different direction."

Just as Yuuka was about to inquire further about Sparda-Sensei's words, her question was abruptly interrupted by the resounding shout of a masked delinquent.

"Sensei! Please leave the other gangs to us and focus on reclaiming SCHALE!"

The one who had bellowed loudly appeared to be the leader, given the immediate chorus of approval from the other girls in the gang.

"Alright, but be careful, okay? I know you girls are resilient, but I won't tolerate it if my students are harmed because of me. Please call me once you're finished, understood?"

"We understand, Sensei! Please teach us again soon!"

With those words, the masked delinquent gang marched forward, courageously engaging with other delinquent groups and clearing the way for Sparda-Sensei and the girls to to proceed.

"Shall we go?" Sparda-Sensei inquired.

The path before them lay clear and unobstructed, thanks to the newfound alliance between Sparda-Sensei, Ayane, and the masked delinquents.

Yuuka couldn't help but feel deeply perplexed by this astonishing turn of events. Her prior perception of Sparda-Sensei as being relatively powerless in combat had been significantly challenged. While she hadn't witnessed him directly engaging in a physical altercation, his unexpected and invaluable assistance in orchestrating this unexpected alliance left her reevaluating her assumptions about his capabilities.

Lost in her thoughts, Yuuka's mind wandered into a realm of its own, ensnared by her internal contemplations. Unbeknownst to her, Sparda-Sensei had silently come to a standstill, setting the stage for an unexpected collision. Yuuka, still engrossed in her musings, unintentionally collided with his broad back.

"Apologies, Sensei! I wasn't paying attention—" Yuuka began, her words fading as her attention was irresistibly drawn to the astonishing sight that had brought their entire group to an abrupt halt.

"Um... What's our next move?" Iori's voice quivered as she echoed the shared bewilderment that now held them all in its grip.

A formidable obstacle had suddenly appeared in their path, casting a metallic shadow - an actual tank.

"That's... a Crusader! Why is Trinity's tank here?!" Hasumi, a member of Trinity, exclaimed, a mixture of shock and indignation coursing through her.

"Is it legal to drive tanks?" Sparda-Sensei inquired, his curiosity undiminished by the strange situation unfolding before him.

"Well, as long as you have the necessary permits, it's not a problem," Iori attempted to explain, although her words did little to rationalize the surreal moment they found themselves in.

"That's not... never mind," Sparda-Sensei abruptly abandoned further inquiry, recognizing the urgency of the situation as a thick cloud of uncertainty hung in the air.

"And right when SCHALE is right in front of us..." Ayane lamented with a hint of frustration that mirrored the group's collective dismay.

In an attempt to diffuse the escalating tension, Sparda-Sensei interjected with a practical question, "A question for all of you. I've seen you girls withstand bullets without obvious injuries... what would happen if a tank shell were to hit you?"

"Why are you asking the obvious?" Iori retorted, a hint of exasperation in her voice.

"Please, just answer my question," Sparda-Sensei insisted, his unwavering and piercing gaze.

Yuuka decided to provide a straightforward response, her voice tinged with apprehension. "We'd be knocked out, for sure."

"How severe would the injuries be?"

"Well, the most severe recorded case of a student being hit by a tank shell resulted in a coma for nearly two weeks."

Sparda-Sensei nodded thoughtfully, his sharp mind seemed to be exploring a myriad of potential approaches. To the astonishment of all present, he boldly took a resolute step forward, striding purposefully towards the menacing tank that had sent shockwaves of terror through the streets.

"Sensei, stop! Where are you going?!" Yuuka's voice trembled with palpable panic as she tried to halt his dangerous advance.

"Where, you ask? Dealing with that tank, naturally," Sparda-Sensei responded with an air of calm determination, as though it were the most ordinary course of action in the world.

"Sensei, I must object! This is a far cry from dealing with mere students. You can't reason or negotiate with a tank!" Hasumi urgently emphasized, her desperation seeping into her words.

"So, you expect me to leave it to you, then?" Sparda-Sensei quirked an eyebrow, his voice tinged with a touch of sardonic humor.

"Exactly," Hasumi nodded with conviction.

"Even if it places you in grave danger?" Sparda-Sensei's question was accompanied by a wry chuckle, making it clear that he had no intention of heeding their pleas. "Sorry, kid. I can't do that."

Sparda-Sensei continued his relentless approach towards the tank, a surreal and perilous situation that left the four young women simultaneously awestruck and deeply concerned.

"Sensei, you can't be serious!" Yuuka cried out, her voice tinged with desperation. "You can't just confront a tank!"

Ayane chimed in, "Hasumi-san is right! This is madness! It's a tank! You can't reason with it!"

Hasumi, her face etched with worry, added, "Please, Sensei, this is too dangerous for you. Let us handle this situation."

Sparda-Sensei, undaunted by their objections, advanced steadily towards the tank. His unwavering confidence in the face of this seemingly insurmountable obstacle left the four young women baffled and deeply anxious.

"What is your plan, Sensei?" Ayane muttered, her voice marked by curiosity and anxiety.

"Sparda-Sensei adopted an almost playful demeanor as he turned to address the students sealed within the tank. "To the students inside the tank, may I kindly request your exit from the vehicle? Let's have a civilized conversation, shall we?" His plea was met with a protracted and heavy silence, as the students within the tank mulled over their options.

Yuuka was on the verge of physically shaking some sense into Sensei. After all, if those students were of the reasonable sort, they wouldn't have embarked on a tank-driven rampage in the first place.

In a collective moment of decision, the students inside the tank rotated the turret, taking deliberate aim at Sparda-Sensei. With a deafening roar, they unleashed the full might of their weaponry. The tank shell cut through the street, a deadly silver streak hurtling inexorably towards its target. Panic washed over the bystanders as they scrambled to react in time to save their sensei.

"Kids these days…" Sparda-Sensei's voice pierced the tension, tinged with exasperation, just as the shell hurtled toward him.

SHIIIIIIING!

Amidst the impending catastrophe, a sudden and eerie sound cut through the air, and inexplicably, the expected explosion failed to manifest. Yuuka, her eyes squeezed shut in dread, couldn't believe her senses when she opened them. Before her stood Sparda-Sensei, unscathed and poised. In his right hand, he held a gleaming katana, and in his left, its sheath.

The source of the katana remained a baffling enigma for Yuuka, considering that Sparda-Sensei had been unarmed mere moments ago. The question spun in her mind, but it was swiftly eclipsed by the extraordinary spectacle unfolding before her eyes.

"Unbelievable!" Ayane exclaimed, her eyes wide as saucers. "That's—"

Lying on the asphalt, the two cleanly sliced halves of the tank shell were neatly separated, preventing them from detonating upon impact. Yuuka stared at the severed pieces, then back at the katana firmly gripped in Sparda-Sensei's hand. Her mind rebelled against the implausible, but the evidence was irrefutable.

"Now then…" Sparda-Sensei's voice, though seemingly relaxed, harbored an undertone of menace that sent shivers down Yuuka's spine.

"Girls...lesson one," Sparda-Sensei declared, "You must understand that in this world, actions have consequences. For instance, firing upon unarmed individuals might earn you a stern reprimand... and the forfeiture of your tank." With a single graceful motion, the tank disintegrated into pieces, leaving only the two dumbfounded students wearing construction worker helmets inside, gaping in astonishment at their sudden exposure.

"Well, well, well," Sparda-Sensei sauntered over to the students and leaned down, his voice carrying a measured threat. "Would you like to continue the lesson, or would you prefer to return home?"

The two students exchanged frightened glances and promptly opted for the latter, scurrying away from the enigmatic man who had just dealt with their tank with apparent ease.

"Hahahaha…they're quite spirited," Sparda-Sensei mused, his tone oddly casual considering the extraordinary feat he had just accomplished.

Sparda-Sensei, seemingly unfazed by the surreal turn of events, turned back to the group with a casual grin. "Well, that's one way to solve a problem, wouldn't you say?"

Still grappling with the sheer impossibility of what she had witnessed, Yuuka nodded in stunned agreement. "Sensei, that was... unbelievable."

Sparda-Sensei, now sheathing his katana, had not only defied the laws of physics by splitting a tank shell mid-air but had also effortlessly dismantled the tank itself, leaving only bewildered students behind.

The atmosphere in the street had transformed from one of panic and dread to a mix of amazement and respect for Sparda-Sensei's incredible display of power and control. Even the masked delinquents, who had been poised to assist in engaging with the tank just moments before, were now in a state of shock and bewilderment.

Iori, her voice filled with a blend of admiration and bewilderment, chimed in. "I don't know how you did it, Sensei."

Hasumi, unable to contain her curiosity, couldn't help but press the issue. "Sensei, where did that katana come from? And how on earth did you manage to slice a tank like that?"

Sparda-Sensei's chuckle was both amused and enigmatic, as if he savored the intrigue he had sparked. "Ah, well, some things are better left as mysteries, my young friends. Let's just say that I have a few tricks up my sleeve."

Yuuka had a myriad of questions bubbling within her, a curiosity she was itching to satisfy. However, Sparda-Sensei seemed to have other plans, and he swiftly made his way towards SCHALE. But, just as he was about to ascend the stairs leading to the entrance, he spun around with an unexpected flourish.

And then, as if hit by an impromptu inspiration, he initiated a roll call.

"Okuzora Ayane!"

A startled Ayane responded almost jumping at the sound of her name being called.

"Shiromi Iori!"

Iori, taken aback, retorted, "Why are you suddenly yelling our names like that?" Her irritation was unmistakable.

"Hanekawa Hasumi!"

Hasumi seemed to grasp the purpose behind Sparda-Sensei's actions, a dawning realization evident in her expression.

"Hayase Yuuka!"

Yuuka couldn't help but protest, "Sensei, could you not shout our names so loudly? It's honestly embarrassing!"

However, her protest only elicited a hearty chuckle from Sparda-Sensei.

"Nothing's wrong with being energetic, right? If anything, you need to be wild, to embrace the exuberance of youth while you can," Sparda-Sensei remarked, leaving Yuuka bewildered about what exactly he meant by 'wild.' Should they act more rambunctiously like the students from Gehenna?

"Anyway," Sparda-Sensei mused, a glint of enthusiasm lighting up his eyes, "I believe roll call is a wonderful tradition. It provides me with the invaluable opportunity to connect names with the vibrant faces of my cherished students. If I had my way, I'd conduct it for every single lesson."

"Now, while I'm tempted to invite you lovely young ladies inside," he continued, a sly smile playing on his lips, "it seems that a little tidying up is in order before we proceed. Your efforts have not gone unnoticed, and I am immensely grateful for your services. Rest assured, I won't soon forget what you've accomplished today, and I fervently hope our paths cross again in the near future."

It was then that Yuuka had her epiphany. Sparda-Sensei was essentially bidding them adieu. Yet, a lingering question demanded an answer.

"Are you telling us to leave, Sensei?" Iori queried.

Sparda-Sensei leaned closer, his voice a conspiratorial whisper, "No. I'm indicating that, from this moment onward, you are entering the domain of the General Student Council. There might be certain permits required to access SCHALE, and I'd hate to see you in any hot water for wandering into this particular abode."

Yuuka nodded in understanding, recalling Iori's previous misadventure concerning unauthorized entry into the General Student Council's territory.

"I see. That makes perfect sense. Sensei, I suppose we shall bid you farewell, for now? Hasumi chimed in, accepting Saprda-Sensei's reasoning. She turned to head away, but then she casted a wistful look back at Sparda-Sensei, adding, "By the way, Sensei, if you ever decide to visit Trinity, please, do reach out to me. I'd be delighted to arrange a rendezvous with the Tea Party."

Sensei's response, though agreeable, carried a hint of uncertainty. It seemed that the term 'Tea Party' might be unfamiliar to him.

"That sounds interesting. Sure, why not?" he replied, leaving Yuuka to ponder his level of comprehension regarding the Tea Party.

Iori, in her typical candid manner, grumbled, "All that effort, and we didn't even get a peek at SCHALE. Ah well, at least I have an interesting story to tell my colleagues in the Prefect Team," as she departed in the opposite direction from Hasumi.

Ayane approached Sparda-Sensei with a sparkle in her eyes, much like stars illuminating a midnight sky. "Sensei! I'm looking forward to our next meeting!" she exclaimed.

Sensei reciprocated her enthusiasm, stating, "Me too."

"Please stay in touch!" Ayane urged.

"I will, through MomoTalk, right?" Sensei responded.

"Exactly!" Ayane beamed, bowing gracefully before bidding, "Sensei, until our next encounter!" and then set off towards the train station.

Sparda-Sensei observed Ayane's departure with a warm smile, echoing, "Until we meet again."

Watching Ayane's receding figure for a moment, Yuuka couldn't help but revisit a question that seemed to have slipped Sensei's mind.

"Sensei, what about the Fox of Calamity?" Yuuka inquired.

Sparda-Sensei tilted his head, displaying an inquisitive demeanor that took Yuuka by surprise. "The Fox of Calamity?"

"We haven't encountered her thus far," Yuuka pointed out.

Sparda-Sensei raised an intrigued eyebrow, contemplating her words. "And? I don't see an issue with that. Perhaps she grew weary and left earlier. In such a case, we should let her be."

Yuuka attempted to voice her concerns but was preempted by Sparda-Sensei's stern statement. "Yuuka, it's not your responsibility to apprehend her. Your mission was to assist me in regaining control of the SCHALE building," effectively silencing her protest.

Indeed, that cold-hearted vice president had only tasked them with aiding in the recovery of SCHALE, and with the imminent threats from the delinquents diffused and the tank incapacitated, their support was no longer required.

With a hint of disappointment, Yuuka conceded, her spirits slightly deflated. She made the decision to return to Millennium and set about the task of compiling a meticulous report, determined to capture every detail of the day's events.

"Very well, Sensei," she responded, her voice tinged with resignation. Then, her expression shifted, displaying a playful grin. "By the way, Sensei, I bet what happened today had already spread all over the social media, so if you ever require my assistance to help deal with the infamy, please don't hesitate to give me a call."

"I will. Thank you, Yuuka," Sensei replied warmly.

As Yuuka turned to depart, an inexplicable warmth spread across her cheeks at the sight of the smile on Sparda-Sensei's face. She couldn't quite fathom why his smile had such an effect on her, but she dismissed any peculiar thoughts and continued on her way, making her way to the train station that would transport her back to Millennium.

However, a nagging thought lingered in the back of her mind, compelling her to steal a glance back at SCHALE. Sensei had already disappeared into the building, but that wasn't what captured her attention.

The vice president's words echoed within her mind as she quietly muttered to herself, "If Sensei had been granted authority over the Sanctum Tower... then, couldn't he have issued those permits without requiring the General Student Council's approval?"

o-0-o

Sparda surveyed the lobby of the building, taking in the intriguing scene that lay before him. Despite the recent turmoil outside, SCHALE had remained surprisingly unscathed. Although some of the furniture had been hastily rearranged to serve as makeshift barriers, there was no discernible lasting damage. The building had weathered the storm with an unexpected grace.

Silently, Sparda found himself extending his apologies to Ayane, Hasumi, Iori, and Yuuka. He had hurriedly ushered them home due to his sense of a dangerous presence lurking within SCHALE – a presence teeming with bloodlust.

Trusting his instincts, he ventured deeper into the building, where darkness had descended due to a power outage. Navigating through the obscurity proved effortless for him. In fact, the lack of illumination allowed him to move discreetly and keep his presence shrouded.

Within a minute, he found himself in an open, spacious area, standing before the source of the ominous bloodlust. Taking cover behind a pillar, he observed the enigmatic figure with caution.

In the center of the area stood a long-haired girl with fox ears. She was adorned in a furisode, asymmetrical leggings, and boots, and her face was concealed by a kitsune fox mask. Above her head hovered a halo featuring a black cherry blossom encircled by a combination of sniper sights and anarchy symbols. A bayonet rested on her shoulders, and she appeared lost in her thoughts.

A name escaped Sparda's lips, perplexing him.

"Wakamo."

...

...

...

"Huh?"

Sparda couldn't help but wonder why he felt so certain that the girl before him was Wakamo. Furthermore, who was Wakamo? Even though the girl wore a fox mask and fox ears, leading him to believe she was the notorious 'Fox of Calamity,' he couldn't explain why the name 'Wakamo' immediately sprang to mind.

"Hmm?"

The masked girl turned her attention toward Sparda, her gaze seemingly able to pierce the darkness and lock onto his hiding spot.

"My? It seems a rat managed to slip in without me noticing," Wakamo remarked with a sweet tone, albeit underscored by an aura of danger.

With a resigned sigh, Sparda realized there was no point in continuing to hide. He stepped out from behind the pillar, moving closer until they stood in plain view of each other. Despite the dimness, it was as if they could see each other perfectly.

"You are…" Wakamo began, leaving room for Sparda to start the conversation.

"You seem to like this place," Sparda commented, trying to initiate a conversation. "I find it rather cozy, though it could use some sprucing up. If you have any suggestions to make it more inviting, I'm all ears."

...

No response. It seemed a different approach was necessary.

"Oh, forgive my rudeness. My name is Sparda. I've been appointed as Sensei today. If you have any problems that require my assistance, please feel free to come to me."

...

Still, there was no reaction from the girl. She was proving to be quite enigmatic.

Sparda was on the verge of trying a different approach when he noticed tears streaming down the girl's mask.

"Are you... crying?"

"I—what?"

"Are you alright?"

"I—umm, I'm al—waaaahh!"

Sparda was taken by surprise as Wakamo suddenly burst into uncontrollable wailing and crying.

"Oh, um..." Sparda found himself at a loss. He wanted to offer comfort, but he had no understanding of why she was crying in the first place.

The intensity of her crying caused her mask to fall off, revealing a girl whose face was a mess of tears and snot. Her eyes reflected confusion and sorrow, as if she herself didn't know why she was crying.

"I—I'm sorry!" Wakamo hurried past Sparda, leaving him alone to ponder the strange turn of events.

"What in the world?" Sparda mumbled, utterly bewildered by the unexpected and mystifying circumstances.

He wanted to follow Wakamo and learn more, but the sound of an aircraft landing made him realize that disappearing abruptly might not be the best course of action.

As if on cue, footsteps could be heard descending the stairs from the upper floor. The emergency lights flickered to life, revealing Rin's arrival, with her gun holstered at her side.

"Hey, Rin, you're late," Sparda greeted her casually.

Rin instinctively moved her hand to her gun. "Forgive my tardiness, you scum."

...

...

...

"What did you just call me?" Sparda inquired, unsure if he had heard it correctly.

"Scum, you scum," Rin repeated, her voice oozing with venom.

"Uhh, I don't understand," Sparda scratched his chin, genuinely perplexed.

Rin pushed up her glasses, glaring at him and said, "I saw the Fox of Calamity run out of the building, crying and looking like a mess. And since you were the only one here..."

"No, wait a second! Don't jump to conclusions! It's definitely not what you're thinking!" Sparda pleaded, though his defense did little to alter Rin's impression of him.

o-0-o

Sparda slumped into the sofa in the basement, feeling utterly drained after enduring his second round of questioning by Rin. The intensity of the interrogation left him wondering what had triggered such suspicion and scrutiny. He pondered what he might have done to warrant this level of distrust and whether Rin was genuinely wary of him. Their earlier banter, which he had believed was all in good fun, now seemed to have been taken more seriously by Rin.

"Sensei..." Rin's voice broke the silence.

Sparda's eyebrows raised slightly as he responded, "Oh?"

He had considered making a lighthearted comment about Rin no longer referring to him as 'scum,' but he decided against it when he noticed her holding a device that closely resembled a smartphone but on a larger scale.

"Do you know what this is, Sensei?" Rin asked, her tone curious.

Sparda, somewhat cautiously, replied, "...A big smartphone?"

Rin let out a sigh of exasperation, marking the second-most significant one he had heard from her today.

"Sensei, this item here is the Shittim Chest. And, no, it's not a smartphone; it's a tablet," Rin clarified.

Sparda nodded, taking in the new information. "Oh, so this is the Shittim Chest. I thought it was like a giant treasure chest or something. What am I supposed to do with it?" he inquired, genuinely curious.

Rin suggested, "Why don't you try turning it on?"

"Sure..." Sparda pressed his finger against the tablet's surface, causing it to spring to life. However, it immediately prompted him for a password.

Sparda was on the verge of admitting that he had no idea what the password was, but almost instinctively, his fingers began typing on the tablet's surface.

We long for the seven wailings. We bear the koan of Jericho.

Password accepted.

Welcome to the Shittim Chest, Sparda-Sensei.

"It's working."

"I see…"

"Where are you going?"

"My job here is done. I'll step away so as not to interfere," Rin said, leaving Sparda alone in the basement.

Sparda turned back his attention to the Shittim Chest, and noticed that a change had occurred.

The screen transitioned to a loading screen, indicating that the tablet was establishing a connection with something. The nature of this connection left Sparda genuinely puzzled, and he couldn't help but question how he even knew the password for this tablet. The whole situation left him in a state of genuine perplexity.

Question after question had dominated Sparda's interaction, casting a veil of uncertainty over his role in this bewildering city. Clarity remained elusive, and answers proved elusive. The enigmatic screen danced to another transition, revealing the interior of a timeworn school building, its backdrop a picturesque beach and the endless expanse of the ocean. A solitary occupant rested within, a young girl with cerulean locks cascading to her shoulders, adorned with a white ribbon, slumbering soundly on a weathered table.

"Munnyaaaa~," she softly murmured.

Sparda found himself at a loss for action, though a strange sense of recognition tugged at the corners of his mind. With a tentative touch, he pressed a finger to the screen, jolting the slumbering girl from her dreams.

"Wawawa! I'm not sleeping!" she proclaimed, her eyes wide with surprise. "Eh...?"

"Good morning," Sparda greeted.

The girl's eyes widened in delight. "Wah...since you're here, could you be Sparda-Sensei?"

"I am," he confirmed.

A joyful exclamation followed, "Waaah! Nice to meet you, Sensei! I'm so happy to finally meet you!"

"Likewise," Sparda replied, a smile tugging at the corners of his lips.

"Oh, I wasn't sleeping just now, okay. It's just since there's nothing to be done while waiting for your arrival, I was... I was... going into energy-saver mode!" the girl explained, her laughter echoing through the screen.

Sparda chuckled warmly, intrigued by her quirky demeanor. "I don't know what that means, but good for you, I guess?"

"Ehehehe~!" The girl's laughter held an enchanting note, further deepening the intrigue of the moment.

Amidst their banter, Spard steered the conversation back to the matter at hand. "Anyway, Arona, can you help me restore control of Sanctum Tower?"

With wide-eyed enthusiasm, she responded, "Of course, Sensei! It's easy peasy! I just need your biome...wait—Sensei, have I introduced my name to you?"

Sparda was momentarily taken aback, his mind racing to piece together the mysterious puzzle before him. Arona had, indeed, never disclosed her name.

"You—" Sparda began, but he checked himself before confirming her observation. No, she hadn't introduced herself.

"Sensei..." Arona's voice trembled as she gazed at him with a mix of curiosity and awe. Then, her eyes sparkled with intrigue. "As expected of Sensei, you're amazing! You must have done extensive research beforehand, haven't you? Or, or, perhaps you have psychic abilities? Like seeing the future or giving you answers to any questions you ask?" Arona's excitement brimmed as she voiced her fantastical speculations.

Sparda played along with a wry smile. "Sure, let's go with that," he replied, masking his inner unease. His inexplicable knowledge of individuals he had never met before was becoming an unsettling pattern.

Deep down, a growing concern nagged at Sparda. First with Wakamo, and now with Arona, he possessed information he couldn't recall acquiring. The enigma surrounding his own mind left him unsettled, and he pondered whether it might be wise to take up Yuuka's offer of an examination at Millennium Academy or whatever its name was.

"Sensei?"

Sparda took a deep breath. "As I said, please restore control of Sanctum Tower."

"Sure! Sensei, please, place your finger on mine," Arona requested, extending her finger toward the screen.

Sparda, unsure of the significance of this gesture, obliged and placed his left index finger on the screen.

Arona's determination was palpable as she murmured, "Mmmmmmmmmmmmmmmmmmmmmmmmmmm!"

"Arona?" Sparda sweatdropped as he observed the young girl's efforts.

With a triumphant grin, Arona announced, "Biological Authorization complete! Congrats, Sensei! You now have full access to Sanctum Tower!"

As the lights flickered back to life and the hum of machinery filled his ears, Sparda realized that Sanctum Tower had indeed sprung back to life. Or, at least he assumed it had, a realization that prompted him to consider confirmation with Rin once this interaction concluded.

But his priority remained unchanged. "Thank you, Arona. Next, I want you to transfer control of Sanctum Tower to the General Student Council."

"Ehh? Sensei, you don't want to keep it for yourself?" Arona inquired, her surprise evident.

"Arona... I just learned how to use a smartphone today. What makes you think it's safe to leave something this complex in my hands? Besides, this is their city. They should be the ones to decide how it is run," Sparda reasoned.

Arona pondered his words for a moment, then shrugged. "Well... if you say so, Sensei..."

"Ah, however," Sparda added, "Arona, can you implement terms of use? There needs to be safeguards in place to prevent a repeat of this chaos."

"Umm... sure, it's possible," Arona confirmed.

"Good, now listen carefully..."

And so, Sparda found himself immersed in crafting the terms of use for Sanctum Tower, a process that spanned nearly two hours. Arona's difficulties in comprehending the technical and legal language that flowed from Sparda's mouth were the primary cause of the delay, though it was a necessity to ensure clarity and safety.

Rin found a rare moment of respite in the lounge of SCHALE, the warmth of a hot chocolate cup cradled in her hands. Weeks of unrelenting tension and stress seemed to gradually release their grip on her as she received reports from Ayumu. The revelation that control of Sanctum Tower had been entrusted to the General Student Council by Sensei marked the beginning of their journey to restore Kivotos to its former glory. The burden of gratitude weighed heavily on Rin, and she contemplated expressing her thanks to Sensei for his trust.

However, Sensei remained ensconced in the basement for more than two hours, his activities hidden from her view. Although curiosity nibbled at her, she decided to resist the urge to investigate.

Suddenly, the lounge door slid open, revealing a fatigued Sparda-Sensei. His tired visage was unmistakable, and his raised eyebrow as he noticed Rin's presence elicited a response.

"You're still here?" he questioned, a hint of surprise in his voice.

"Is that a problem?" Rin inquired, her tone reflecting a touch of disappointment.

Sparda-Sensei poured himself a cup of coffee and replied, "No, I'm glad to have some company. So, what's next?"

Rin mirrored his question, "What do you think is next?"

Sparda-Sensei savored his coffee and answered, "I'm not entirely sure, Rin."

A soft smile touched her lips. "Then, allow me to express my gratitude for your hard work, both as the representative of the General Student Council and as Nanagami Rin."

Sparda-Sensei's response was nonchalant. "It wasn't a difficult task."

Rin refused to undersell her appreciation, despite his attempt to downplay his contributions. "Even so, if you weren't here, we would still be grappling in the dark about what to do," she confessed, drawing a scowl from Sparda-Sensei.

"Don't underestimate your own capabilities, Rin," he encouraged. While Rin appreciated his effort to boost her spirits, she acknowledged that without his presence, they would still be ensnared in the tumultuous aftermath of the president's vanishing act.

With a final matter to discuss, Rin revealed her intentions. "Oh, there's one more thing. Please accompany me; I'd like to introduce you properly to the Federal Investigation Club."

Rin beckoned Sparda-Sensei to follow her, and together, they ascended to the second floor. Their footsteps echoed in the hallway until they reached a door adorned with a sheet of paper and a nameplate bearing the inscription 'Independent Federal Investigation Club S.C.H.A.L.E'.

"It's been vacant for quite some time, but now it finally has an occupant," Rin reflected, her fingers brushing against the nameplate.

Rin swung the door open, offering Sparda-Sensei a welcoming smile. "Sensei, welcome to SCHALE."

Author's note:

I'm exhausted. This chapter was supposed to be split into two: Prologue Chapter 2 and Prologue Chapter F. But, for whatever reason, my hands just wouldn't stop typing.

The format of the chapter will be following similar format as in with the game, which will be [Volume Name] [Chapter] [Number] (e.g. Abydos Chapter 1), unless if it's the final chapter of the volume where I will instead use the word 'F' to indicate that it's the final chapter.

Ps. If you have ever read future diary, you'll know how scary and far reaching a psychophatic stalker's love could be.
