Yang's room was a perfect reflection of her personality: vibrant, slightly chaotic, but ultimately cozy. Yang and Jaune were sitting on bean bags in front of the Tv screen playing a game, controllers in hand, utterly engrossed in their current match.

"Ha! Eat that!" Yang crowed as her on-screen character landed a devastating punch, sending Jaune's avatar tumbling off a cliff.

Jaune groaned, slumping back dramatically. "Oh, come on! Who puts a pit right next to the spawn point?"

Yang grinned wickedly. "Someone who knows you'll fall for it every time."

Jaune muttered something about unfair terrain as the next match began. This time, he played more cautiously, his character dodging Yang's aggressive attacks. The game, Infernal Showdown 4, was a chaotic mix of fighting, strategy, and supernatural themes, with demon lords and heroes battling it out in elaborate arenas.

"Who's returning to hell this time?" Jaune quipped as he dodged another attack. "Neo?"

Yang rolled her eyes while mashing buttons furiously. "You forgot about the doctor and his obnoxious assistant? It's those two."

"Oh, right…" Jaune sighed, his shoulders slumping. "I thought they were done with their role. They haven't shown up in a while."

Before Yang could respond, Ruby burst into the room, her silver eyes sparkling with mischief. She didn't even knock, nearly tripping over a pile of Yang's discarded boots as she barged in.

"Hey, hey, Yang! Junior's here!" she announced cheerfully. "Did you tell Jaune about my idea yet?"

Yang blinked, momentarily distracted as Jaune's character took the opportunity to knock hers into a lava pit. "Wait, what idea? Oh… oh right! Yeah, since the doctor's headed back to hell, Ruby wants us to visit her house."

Ruby clasped her hands behind her back, bouncing on her heels. "Yep! Come on, Jaune, it'll be fun! I'll give you guys the grand tour of my mom's castle. It's got secret passages, spooky towers, everything!"

Jaune yawned, stretching lazily. "I don't know, Ruby. Between work at the club and trying to catch up on sleep, I was planning to crash before my shift tonight."

Ruby's smile turned sly, a glint of mischief flashing in her eyes. "Ohhh, by the way, Jaune, Neo told me something interesting. She said if you refuse to come, she might tell Yang about the Maid Situation. You know what she's talking about, don't you? Because I don't know"

The color drained from Jaune's face faster than Yang could finish eating a plate of cookies. "M-Maid Situation?" he stammered.

Suddenly, Jaune's energy returned tenfold. He jumped to his feet, striking a pose that almost knocked over a lamp. "Oh, the underworld? Sounds amazing! Let's go, Yang! Time to embrace the demons!"

Yang blinked, utterly baffled. "Wait, wait, what is this about a 'Maid Situation'?"

But Jaune ignored her, grabbing Ruby by the shoulder and practically dragging her out of the room. "We'll have so much fun, Ruby. Lead the way! Yang, hurry up!"

Yang scrambled after them, clearly frustrated. "Hey, idiot! What the hell are you two talking about?"

Ruby snickered under her breath as Jaune maintained his determined march, pretending not to hear Yang's increasingly irritated shouts.

The sound of footsteps echoed down the stairwell as Jaune, Yang, and Ruby descended into the living room of the house.

Junior stood by the far wall, his arms crossed and a stoic expression plastered across his face. Neo lounged lazily nearby, twirling a parasol in her hands, a playful smirk dancing across her lips. Ciel was there too, leaning against a bookshelf, her face permanently stuck in a look of disdain. And then there was him—Merlot—floating ominously in the air like a wraith, black smoke trailing beneath him as he removed his wide-brimmed hat in what seemed like an eerily polite gesture of greeting.

The last, and perhaps most shocking, member of the group was Nora, sitting cross-legged on the couch, swinging her legs like a kid and grinning ear to ear.

Yang blinked, her face twisting into an expression of surprise. "What the—Nora? What are you doing here?"

Ruby clapped a hand to her forehead as if just remembering. "Oh, right. She got here about ten minutes ago. I kinda forgot to mention it."

Nora leaped up in her usual exuberant fashion, pointing a finger at Yang with mock challenge. "I'm here for my rematch, blondie! We're tied—one win, one loss. It's time to settle this properly, don't you think?"

Yang grinned, a spark of competitive fire lighting up her eyes. "Oh, I can definitely beat you again if you're that desperate to lose. Bring it on, Valkyrie."

Ruby interjected, her tone light and teasing. "Yeah, I ended up inviting her to come along. You two can fight in the royal arena at the castle. It'll be a great show."

Jaune leaned toward Ruby, his voice low and uncertain. "Hey, is it really okay to invite her? I thought this whole demon thing was supposed to be… you know, a secret."

Ruby waved off his concern with an easy smile. "Relax, Jaune. According to Yang, Nora already met one contractor a while back."

Jaune blinked, his mind snapping back to the words Nora had thrown at Yang during their last match. "Right… I guess she already knows something's off, even if she doesn't have the full picture."

"Pretty much," Ruby replied with a wink.

Nora bounced over to Yang, her grin never faltering. "So your sister said we're going to her castle or something? What's that about? Is she secretly a princess?"

Jaune froze for a moment, suppressing the thought that immediately rose in his mind. "Well, technically, Ruby is a princess… the princess of hell". He wisely kept that detail to himself, instead scratching the back of his head awkwardly.

Meanwhile, Junior, who had been silently watching the scene unfold, decided to cut through the chatter. "If we're going, we'd better move. Jaune and I still have work tonight, and we can't waste too much time."

Yang frowned, looking at the clock on the wall. "You've got, what, six hours before the club opens? That's plenty of time."

Without another word, Junior's body began to shift. The transformation was as sudden as it was unsettling—his human frame melting away into something far more otherworldly.

Ruby, brimming with excitement, was the first to act. Without hesitation, she sprinted toward Junior. Her cloak billowed behind her as she leaped into the towering demon's otherworldly form. The moment she entered, the celestial patterns on Junior's surface pulsed briefly with a soft, radiant glow, then returned to their steady shimmer. Neo was next.

Merlot followed shortly after, gliding through the air with his typical unnerving grace. He adjusted his wide-brimmed hat as he vanished into Junior, his form dissipating into dark smoke as he entered. Ciel was next, her expression unchanging as she walked briskly toward Junior. Her white doctor's coat fluttered slightly as she stepped through his towering figure, disappearing without a word.

Nora, standing a few steps away, watched the scene unfold with wide, curious eyes. A grin slowly spread across her face, but the incredulous tone in her voice betrayed her surprise. "I have no idea what's going on here, but this is awesome. He looks like some kind of creature from another dimension. Someone want to explain what's up with that?"

Yang chuckled, crossing her arms casually. "Well, he's a demon. Same as the rest of them. It's just you, me, and Jaune who are normal humans."

Jaune shot her a skeptical look, his thoughts racing. "Yeah, I wouldn't call you or Nora 'normal humans.' Pretty sure I'm the only one here who qualifies."

Nora's jaw dropped slightly, her enthusiasm as unrelenting as ever. "Wait, wait—like, actual demons? So they're super strong, right? This is getting better and better. Maybe I could have some fun with them."

Jaune let out a weary sigh, his thoughts laced with exasperation."Of course, the first thing she thinks about is fighting. She's way too much like Yang."

Yang smirked, clearly amused by Nora's reaction. "Well, I know Neo's pretty strong. I've always wanted to fight her. She annoys me to no end, but I've never had the chance."

Jaune couldn't help but think "Neo would probably wipe the floor with Yang. Sure, Yang has ridiculous strength, but she's still just human. Then again… maybe her contract with Ruby would even the odds. Huh. Now I kinda want to see that fight." He glanced at the group, realizing time was slipping away. "Oh, wait—we're wasting time."

He stepped toward Junior, motioning for the others to follow. "Yang, Nora, let's move."

Jaune entered Junior's form with a resigned expression, disappearing into the swirling patterns.

Nora tilted her head, a thoughtful expression briefly crossing her features before she broke into a grin. "This is as ridiculous as the kind of stuff my old teacher used to do. Think she was mixed up with demons too?"

Yang raised her arm, revealing the rose-in-circle emblem of Belphegor etched into her skin. "You said she had a mark like this, right? It's possible she had a contract with a demon."

Nora's eyes lingered on the emblem as her voice softened slightly. "Since I was a kid, I always thought that mark meant she was special—someone extraordinary. When I saw it on you, I knew you were the same, Yang. Just like her. Every time I watch you, I can't help but think of her. You're so much alike… except, you know, blonde. She had black hair."

Before Nora could continue, Junior gave a low, rumbling cough, clearly impatient. Yang smirked, placing a hand on Nora's shoulder. "Right. Let's go, Nora. We'll have our rematch in my sister's castle."

Nora's grin returned in full force as the two of them bolted toward Junior. Together, they vanished into his towering form, leaving the room empty and silent.

(…)

Yang awoke to an unfamiliar sensation—the strange weightlessness of floating. Her eyes fluttered open, and she blinked against the bright, shimmering light that stretched endlessly around her. She twisted her body, trying to get her bearings, but there was nothing—no land, no horizon, only an infinite expanse of rippling water in every direction.

"Is this… the ocean?" She murmured, her voice barely above a whisper.

Before she could process the surreal scene, a sudden splash echoed nearby. Yang's head snapped toward the source, and she caught sight of a figure breaking through the water's surface, gasping silently.

"Neo?" Yang called out, her voice tinged with confusion.

Neo, drenched and disoriented, flailed slightly before steadying herself. Her mismatched eyes darted around in a frantic search for answers, her usual smug demeanor replaced by something rare and unsettling—fear.

Yang frowned, concern tightening in her chest. "Neo, what the hell happened? Are we still in the human world? Did Junior screw up and dump us in the middle of the ocean or something?"

Neo froze mid-glance, her expression tense, and Yang felt her heart sink. This wasn't good. Before Yang could press further, Neo's voice reverberated inside her mind, clear and sharp as a blade.

"No… We made the journey. This is the demon world. But something went wrong with Junior's teleportation. I don't know how, but I do know where we are—and it's bad. This is Leviathan's domain. His kingdom"

Yang blinked, her golden eyes scanning the endless sea that surrounded them. It was just water. Nothing but water. She turned back to Neo, incredulous. "This is a kingdom? There's nothing here but the ocean!"

Neo didn't answer. Instead, she seemed to steel herself, the fear still lingering at the edges of her gaze. Without warning, she took a deep breath and plunged beneath the surface.

"Hey—Neo! What the hell are you doing?!" Yang shouted after her, panic creeping into her voice

.

Neo's figure disappeared in an instant, swallowed by the depths below. Yang cursed under her breath before taking in a shaky breath of her own. "Screw it." She couldn't let Neo just vanish on her.

Without further hesitation, Yang dove into the water, the cool current shocking against her skin as she descended. Her vision adjusted to the shifting blue, and she squinted into the murky depths. What she saw stole the breath from her lungs.

"What the hell…?"

A vast city sprawled out beneath her, ancient and otherworldly, its darkened spires reaching up like claws toward the surface. Structures of impossible design loomed through the hazy water, their edges sharp and foreboding. The city stretched for miles, as far as Yang's eyes could see.

Her mind raced, trying to make sense of it all. "Is this—an underwater city?"

The weight of the revelation settled heavily on her, a chill running down her spine that had nothing to do with the cold water.

(…)

Jaune's retching echoed through the dim chamber as he hunched over in a corner, his body still reeling from the tumultuous journey. Nora knelt beside him, her expression uncharacteristically worried as she lightly patted his back.

"Hey, John, you okay? Or do you need a minute to rest?"

Jaune wiped his mouth with the edge of his sleeve, letting out a shaky breath before muttering, "It's Jaune, not John." His voice wavered, but he pushed himself upright, straightening his posture despite his pale complexion. "And don't worry. The trip was just… rough. I'll be fine."

Nearby, Ciel stood with her arms crossed, surveying their surroundings. Her eyes moved over the grand hall they now occupied—a space that would have been magnificent if not for its oppressive, eerie atmosphere. To Jaune's surprise, there was an odd, almost smug smile tugging at the corner of her lips—something completely out of character.

"Then… this is the castle of Yang's sister?" Nora asked, standing up and looking around with visible curiosity. Her voice carried a faint edge of excitement, but Jaune's unease only deepened.

"I don't know," Jaune admitted, his eyes narrowing warily as he scanned the area. "Something feels wrong. It's just the three of us here, and we have no idea what happened to the others."

At this, Ciel turned to face them, her cold eyes glinting with amusement. "It's very likely that you'll all die soon," she said matter-of-factly. "But at the very least, try to serve as a distraction, will you?"

Jaune and Nora stared at her, dumbfounded.

"What are you—?" Jaune began, but his words were cut short when Ciel raised her right hand, her palm aimed toward one of the walls.

Jaune's heart skipped a beat as he noticed it—the faint shimmer of energy, pulsing and gathering in her outstretched hand. Before he could react, a blast of searing blue energy erupted from her palm, slamming into the stone wall. The explosion roared through the hall, shattering the structure in an instant and sending a shower of debris flying. A thick curtain of smoke and dust engulfed the room, blotting out everything.

Jaune coughed, waving a hand to clear the air, his mind racing. "What the hell—?"

When the smoke finally began to settle, Jaune's eyes darted around the chamber. Ciel was gone. She had vanished without a trace.

"Why would she do that?" Jaune muttered under his breath, his voice laced with frustration and confusion.

"Uh, Jauney? I think you might want to see this," Nora's voice cut in, her tone unusually serious.

Jaune turned to find Nora standing by a nearby window. Her gaze was fixed outside, her expression a mix of wonder and something darker—disquiet. Swallowing hard, Jaune hurried to her side. He looked out, and his breath caught in his throat.

Beyond the cracked glass, an otherworldly sight stretched out before them. The castle they stood in was submerged beneath the ocean. Faint beams of sunlight pierced the murky depths, illuminating schools of fish that drifted lazily through the water. Massive sea creatures, their silhouettes vast and haunting, swam in the distance, casting ominous shadows over the darkened seabed. The castle's exterior loomed in the gloom like an ancient titan. Its spires and towers were jagged and twisted, their architecture alien and gothic. Stone arches curled impossibly, almost like the ribs of a colossal beast, and strange runes glowed faintly along the outer walls, casting an eerie, spectral blue light across the seascape.

The water seemed endless—an abyss that swallowed light and sound alike.

"Oh no," Jaune muttered, his face pale with realization. "This… this doesn't look good."

Before Nora could reply, a sudden commotion erupted from somewhere deeper in the castle. They could hear frantic voices—shouts of alarm echoing down the corridors—and the heavy thud of footsteps as guards hurried through the halls.

"Sound the alarm! Intruders in the castle!" someone yelled.

Jaune's instincts kicked in. He grabbed Nora's arm, his grip firm. "We're leaving. Now."

"Hey, Jauney, wait! Maybe I could fight a little!" Nora protested, her grin returning, a spark of excitement in her eyes.

"Not happening," Jaune snapped, pulling her along as he darted toward a side corridor. He didn't let go of her for even a second, his mind racing with a sense of dread he couldn't shake.

"This isn't good", he thought, his breath ragged as they ran. "If they're calling us intruders, then this definitely isn't Ruby's castle. Nora's strong, sure, but I don't know how well she'd hold up against actual demons. She doesn't have a contract. For now, we need to hide and regroup."

His thoughts darkened further. "And Ciel… she did that on purpose. She wanted to attract the guards. Whatever she's planning, it's not good."

(…)

Yang stood outside an underwater restaurant, arms crossed as she leaned casually against the wall. Her gaze wandered across the bustling city square, though her expression betrayed a mix of awe and bemusement. Above the arching stone gates at the far end of a plaza, a carved inscription proudly proclaimed the city's name: Levia. Yang couldn't help but snort softly to herself.

"Seriously? Levia? In The kingdom of Leviathan? That's got to be the most unoriginal name I've ever heard."

The words felt strange on her tongue, not least because she was somehow speaking underwater. It was an uncanny sensation, though far less unsettling than the changes to her body. Yang lifted a hand to brush the faint ridges along her neck where newly-formed gills allowed her to breathe with ease. On her back, just below her shoulder blades, delicate, translucent fins shifted slightly with each movement. Courtesy of Neo, of course—who had procured a potion that granted them these aquatic adaptations.

Apparently, such potions were common among travelers and tourists who wished to explore the depths of Leviathan's realm. Yang still wasn't entirely comfortable with the changes, but at the very least, they let her breathe. That was better than nothing.

The city of Levia itself was a marvel—a place both strange and beautiful. Towering coral-like buildings spiraled upwards, glowing faintly with soft blues, greens, and purples. Bioluminescent plants lined the stone streets, casting shimmering patterns onto the cobbled pathways that twisted and curved in ways Yang couldn't quite wrap her head around. At every corner, arches and domes formed elegant tunnels of translucent material, allowing streams of light to filter down from above.

The streets teemed with life. The inhabitants of Levia bustled about in ways that, to Yang, almost mirrored the behavior of humans in the mortal world. Yet their appearances were far from ordinary. Many of them looked human at first glance, but on closer inspection, their fish-like features became apparent: shimmering scales tracing their skin, fins extending from arms and legs, webbed hands, and eyes that gleamed like polished pearls. Some individuals were far less subtle—full-bodied fish-like demons with broad, armored heads, elongated limbs, and mouths lined with rows of needle-sharp teeth. Yang even caught glimpses of siren-like figures lounging on ledges above the street, their glimmering tails flicking lazily through the water as they watched the city below.

And yet, none of these creatures seemed hostile. In fact, they barely gave Yang a second glance as they passed by, their attention fixed on their own affairs. Neo had explained that the potion worked not only to allow breathing underwater but also to grant them temporary physical traits that blended in with Leviathan's aquatic citizens. Yang's golden hair floated lazily around her face, her fins shifting in rhythm with the gentle currents, and it was apparently enough to make her look like she belonged—at least to those who weren't paying close attention.

For now, they seemed safe.

Yang sighed and tilted her head back, her gaze catching the upper levels of the city where graceful bridges connected buildings and creatures swam effortlessly through open spaces. It was beautiful, no doubt about it—otherworldly in every sense—but the fact remained that they were lost in an unfamiliar place.

A soft ripple nearby drew her attention. Neo emerged from the restaurant, stepping gracefully onto the street as if she hadn't just conducted whatever business she'd needed to inside. Her expression was calm, but there was something in her mismatched eyes—a flicker of tension beneath that veneer of confidence.

Yang pushed off the wall and straightened. "Well? What's the verdict?"

"I managed to contact Junior," Neo's voice echoed directly into Yang's mind—her usual method of 'speaking.' "He made it to Madam Summer's castle along with Lady Ruby and the doctor."

Yang felt a surge of relief at the mention of Ruby but frowned at the rest. "And Jaune, Nora, and that Ciel bitch?"

Neo's expression darkened slightly, her playful demeanor slipping for just a moment. "They're not there. Junior's injured—something happened during the teleportation. He's not sure what caused the problem, but it's clear that it split us up and sent us here instead of to the castle."

Yang's brows furrowed. "no good"

Neo shook her head. "He's certain they're somewhere in this realm, but finding them will be… difficult. Levia is big and there are other places, and we're not exactly on home turf here. For now, he just hopes they can survive on their own. Lady Ruby is a friend of someone from the royal family of Leviathan, she will ask that person to help find the others, while we search Levia to see if anyone arrived here."

Yang exhaled sharply, crossing her arms as she stared down the busy street. Her thoughts turned to Jaune and Nora. "Let's hope they don't get into too much trouble"

(…)

Jaune's boots pounded against the cold stone floor, his breath coming in ragged gasps as he darted through the labyrinthine corridors of the castle. Panic gripped him, the shouts of his pursuers echoing relentlessly behind him.

"I hope Nora's okay," Jaune muttered under his breath, his chest heaving. The chaos that had erupted earlier had separated them.

"Don't let the intruder escape!" A gruff voice barked, the sound dangerously close now. The thudding of armored footsteps grew louder, relentless in their pursuit.

"Shit, shit, shit" Jaune hissed, his heart pounding in his ears. His instincts screamed at him to move faster, to escape, but the endless corridors all seemed the same—stretching into the unknown like a nightmarish maze.

Then, at the edge of his vision, Jaune spotted it—a tall, elegant door set into the wall, its surface dark mahogany carved with intricate patterns of swirling sea creatures and delicate runes that glowed faintly blue. Without thinking, he lunged for it, shoving the heavy door open and slipping inside just as the guards rounded the corner. He pressed his back against the cool wood, holding his breath as the sound of boots thundered past.

"He went this way! Keep searching!" a voice barked.

Jaune waited, every muscle in his body tense, until the cacophony began to fade. When silence finally fell, he exhaled a shaky breath and allowed himself to slump against the door.

"Okay… safe for now," he muttered, running a hand through his disheveled blond hair. After a moment, he gathered the nerve to take stock of his surroundings—and froze.

The room was unlike anything he had ever seen. Despite being deep within a submerged castle, it radiated an air of solemn grandeur. The walls were carved from dark stone, their surfaces etched with elaborate motifs of swirling waves and ancient sigils, all shimmering faintly with the same eerie blue luminescence. There were no windows—at least, not in the traditional sense. Instead, a massive glass pane stretched across one wall, giving an unobstructed view of the underwater abyss beyond. Shafts of pale, refracted light filtered through the depths, illuminating the slow drift of silvery fish and the haunting silhouettes of monstrous sea creatures gliding in the distance. The outside world was endless and oppressive, an alien expanse that seemed to watch back.

At the center of the room sat a small, ornate table made of blackened wood, polished to a mirror sheen. Upon it rested a chessboard, its pieces meticulously carved from translucent crystal that glimmered faintly blue—like ice catching the light. A single chair sat on either side, one occupied, the other ominously empty.

And there she was.

At first glance, Jaune thought the figure at the far end of the room might be a doll, her stillness almost unnatural. But no—she was very much alive. The girl's presence was simultaneously ethereal and unsettling, her delicate frame draped in a simple white dress that hung loose around her like a shroud. Her skin was porcelain-pale, almost luminescent under the spectral light. Her face was heartbreakingly beautiful but unsettlingly vacant, as though carved from marble by some divine hand. Her long, dark blue hair cascaded like silk over her shoulders. And then there were her eyes—cold, bottomless pools of sapphire that fixed on Jaune with unblinking intensity, their emptiness pricking at something primal within him.

Jaune's throat went dry, a shiver crawling up his spine as her gaze seemed to pierce straight through him. He swallowed hard, forcing himself to speak.

"Oh, hey," he began awkwardly, raising his hands in a placating gesture. "Looks like I, uh… might've gotten the wrong room. Sorry for the intrusion! I'll just be… going now."

He reached for the door behind him, easing it open with trembling fingers, but before he could slip out, something cold and unyielding wrapped around his arm. Jaune's breath hitched as he realized she had moved. Her slender fingers gripped his forearm with surprising strength, her touch cold. Slowly, Jaune turned his head to face her.

"Oh… you," the girl murmured, her voice soft and melodic, yet devoid of warmth—like a lullaby sung by someone long dead. Her fingers tightened, and Jaune winced, the pressure more than he would have expected from someone with her fragile appearance.

"This feeling…" she continued, tilting her head ever so slightly, her empty gaze never leaving him. "You're a human i think. How curious. It's the first time I've seen one in the flesh."

With her free hand, she reached behind him, pressing the door closed with a hollow thud. Jaune's heart raced as panic surged through him, every instinct screaming at him to get away, yet his limbs refused to obey."Despite her frail appearance, this girl's dangerous. Just being this close to her is making my skin crawl. Am I going to die here?"

Before he could finish the thought, her other hand moved again, and Jaune flinched as her fingers brushed against his face. She cupped his chin gently, turning his head from side to side as though inspecting him—like he were some kind of specimen.

"What a curious creature you are," she murmured, her voice a whisper. "So weak, so insignificant… yet there's something intriguing about you. I assume you possess a degree of intelligence, yes?"

She finally released his face, though her grip on his arm remained firm. A ghost of something that might have been a smile flickered across her pale lips.

"Play with me," she said suddenly, gesturing toward the chessboard. "I'm bored of playing alone. It's no fun when I already know what the other side will do." Her sapphire eyes glinted with something unreadable. "If you entertain me… perhaps I won't tear you to pieces for intruding in my chambers."

Jaune's blood ran cold. He had no doubt that refusing her would mean a swift and painful death. With a jerky nod, he swallowed his fear and forced himself to answer.

"Uh, sure… I'll play."

Her grip loosened, and she let go of his arm, returning to her seat at the table. Jaune rubbed the sore spot absently, watching her warily as she began to reset the chessboard, her movements elegant and precise. The blue crystal pieces shimmered faintly in the dim light as she placed them back into formation.

"Come," she said, her tone cool and detached. "Sit. And while we play, you can tell me how you managed to wander into the castle."

Jaune hesitated, then cautiously moved to the chair opposite her. He lowered himself into it, every muscle in his body tense, as though expecting an attack at any moment. The chessboard lay between them, its pristine surface almost mocking in its serenity. "I am Crayiel Vasilias or Leviathan the III if you wish"

Jaune's breath caught as realization struck him. "Leviathan the III... If I'm not mistaken, Ruby is Belphegor the III. That means this girl belongs to demon royalty. I'm in serious trouble."

The girl's eyes remained fixed on him, cold and unreadable, as she finished arranging the final piece.

"Your move," she said simply, resting her hands in her lap.

Jaune stared at the board, his heart still pounding in his chest. "I don't know what I've gotten myself into, but if playing chess keeps me alive, then I'll play."

(…)

Nora Valkyrie sat triumphantly atop a heap of defeated demon guards, her vibrant orange hair slightly tousled and damp with sweat. Though small cuts adorned her arms and legs, she showed no signs of slowing down, her grin as wide and radiant as ever. Her knuckles were raw but steady, a testament to the sheer force of her physical prowess. Around her, the incapacitated guards—a strange mix of humanoid figures with fish-like features and others leaning grotesquely toward aquatic monstrosities—lay scattered in disarray. She stretched her arms overhead, letting out a relaxed sigh as if she had merely finished a warm-up.

"Geez," she muttered, tapping her foot on the chest of an unconscious guard beneath her. "These fish guys seemed tough at first, but they turned out to be real disappointments." She looked around with a curious tilt of her head. "Huh… I wonder where Jauney ended up."

The sound of heavy, deliberate footsteps interrupted her musings, and a menacing growl reverberated through the corridor. Nora's grin widened as a towering figure emerged from the shadows, its presence radiating power and malice.

The demon was monstrous in stature, standing nearly ten feet tall with a hulking, muscular frame that seemed carved from stone. Its skin was a deep, ominous blue, shimmering faintly as though perpetually slick with water. Jagged, bony protrusions jutted from its shoulders, elbows, and spine, resembling the cruel ridges of a predatory deep-sea creature. Its head was elongated and grotesque, with sharp ridges running along its skull and a gaping maw filled with jagged, uneven teeth that gleamed like broken glass. Two piercing yellow eyes glowed with an unholy light, their slitted pupils fixed intently on Nora.

As it stepped closer, its massive hands, ending in razor-sharp claws, flexed with anticipation. A long, sinuous tail swayed behind it, tipped with a jagged fin that cut through the air like a blade. The creature exuded an aura of dread, its every movement calculated and deliberate, as if relishing the impending confrontation.

It spoke, its voice a deep, guttural rumble that resonated through the hall. "This scent…" It paused, inhaling deeply through its flared nostrils. "To think that several of our guards were defeated by a mere human." It sneered, its lips pulling back to reveal more of its serrated teeth. "I am Nahtaivel, servant of the royal family of Master Leviathan and captain of the royal guard. For the crime of invading our territory, you shall be executed on the spot."

Rather than showing fear, Nora's eyes lit up with exhilaration. She stood, rolling her shoulders and cracking her knuckles, the cuts on her body seemingly forgotten.

"Ooh, now you look like a strong one," she said, her voice brimming with excitement. "My instincts don't lie. I knew tagging along with Yang would be fun, but this? This is even better than I expected." Her grin widened, and she clenched her fists, readying herself for the fight.

"I haven't even got my rematch with Yang yet, but I've already seen so many interesting things. And now," she continued, her gaze locking onto Nahtaivel's glowing eyes, "a formidable opponent like you shows up? I couldn't ask for anything more."

Nahtaivel wasted no time. The ground trembled with each of his thunderous steps as he lunged forward, his massive claw slicing horizontally through the air with lethal precision. Nora ducked low, her movements fluid as she rolled under the swipe. Coming out of the roll, she launched herself upward, her fist aimed directly at the demon's ribs. The blow landed with a sharp crack, though the demon's dense, almost stone-like skin absorbed much of the impact.

Nahtaivel snarled, spinning with surprising agility for his size, his tail whipping through the air. Nora jumped back just in time, the finned tip grazing the front of her tank top. "Whoa! That was close," she quipped, her grin unshaken. "But you'll have to try harder than that, fish-face!"

The demon's yellow eyes flared with annoyance. "You insolent worm!" he roared, lunging again. This time, he brought both of his massive fists down in a hammer strike. Nora crossed her arms and braced herself, catching the brunt of the blow with a shockwave that cracked the floor beneath her feet. Her knees buckled, and her teeth clenched as she absorbed the impact, but she remained standing.

Before Nahtaivel could retract his arms, Nora grabbed one of his wrists with both hands. With a shout, she twisted her hips, using his own weight to flip the hulking demon over her shoulder. The sheer force of the maneuver sent Nahtaivel crashing into the ground, shattering the tiles and sending debris flying.

The demon let out a guttural growl, his claws digging into the ground as he pushed himself up. "For a human… your strength is absurd," he admitted, though his tone was more irritated than impressed.

"Heh you're kind of weird" Nora shot back, bouncing on the balls of her feet.

Nahtaivel's lips curled into a sneer. "Enough games," he growled. His chest heaved, and suddenly, he opened his maw wide, releasing a powerful jet of water aimed directly at Nora. The high-pressure stream tore through the air with a sharp hiss, forcing Nora to leap to the side. The stream narrowly missed her, but the residual spray soaked her hair and clothes.

"Hey!" Nora protested, shaking water from her hands. "What's the big idea?"

The demon didn't respond, instead sweeping the jet across the corridor, forcing Nora to keep moving. She ducked and dodged with agility, her movements a blur as she avoided the destructive torrent. The water carved deep grooves into the walls, sending chunks of stone flying.

As the stream began to wane, Nora saw her chance. She charged forward, weaving through the remnants of the attack. With a battle cry, she leapt into the air, driving her knee toward Nahtaivel's chest. The demon caught her leg with one massive hand, but Nora twisted her body mid-air, using the momentum to slam her other foot into the side of his head. The impact caused him to stagger, releasing her as he reeled back.

Landing lightly on her feet, Nora smirked. "Not bad, huh? You're not the only one who can hit hard!"

Nahtaivel shook his head, his jagged teeth bared in a snarl. "You're skilled," he admitted grudgingly. "But I am not at full strength. I fought someone far stronger not long ago—a warrior of Lucifer's bloodline. Even in my weakened state, however, you should pose no challenge."

"Well, maybe you're just getting weaker!" Nora teased, darting forward again. She feinted a punch, drawing Nahtaivel's guard upward, then ducked low and delivered a brutal uppercut to his stomach. The demon's body jerked, and he let out a low grunt, though he quickly retaliated with a backhanded swipe. Nora managed to block the blow, but the sheer force sent her skidding backward, her boots scraping against the floor.

Despite her confident grin, Nora's arms ached from the impact. "Okay, I'll admit it," she said, shaking out her hands. "You hit like a truck. But I can still keep going!"

Nahtaivel flexed his claws, his glowing eyes narrowing. "You have spirit, human. But it will not save you."

The two combatants surged toward each other once more, their movements a flurry of attacks and counterattacks. Nora's strikes were precise, targeting weak points and exploiting openings, while Nahtaivel's blows were heavy and devastating, each one capable of cratering the ground. Their clash was like a storm contained within the corridor, the air thick with tension and the sound of fists meeting flesh.

Finally, their punches collided—a massive, resounding impact that sent a shockwave rippling through the corridor. Both fighters froze in place, their fists locked together, muscles straining. For a moment, time seemed to stand still, the two combatants locked in an unyielding stalemate.

Nora's eyes sparkled with exhilaration, her grin as wide as ever. "You're tough, I'll give you that. But I'm not backing down."

Nahtaivel growled, his yellow eyes blazing. "Nor will I, human. This is far from over."

(…)

Jaune shifted uneasily in his chair, his fingers brushing against the smooth crystal chess pieces on the board before him. Across the table sat Crayiel, her porcelain features unreadable as she watched him with an unblinking, almost predatory gaze. The room's ethereal blue glow only heightened the sense of otherworldly tension that hung thick in the air.

"Your name," Crayiel said softly, breaking the silence. Her voice was a melody devoid of warmth, like the hum of a distant tide.

"Jaune Arc," he answered, trying to steady his voice.

"Jaune Arc," she repeated, as if testing the weight of it. "A simple name. Tell me, do all humans possess such… unassuming titles?"

"Uh, not all of us," Jaune replied, scratching the back of his neck. "Some names are longer, more complicated. Mine just… isn't."

Crayiel tilted her head ever so slightly, a gesture that seemed more calculated than curious. "I see. And what occupies your days, Jaune Arc? What pursuits give meaning to your existence?"

"Well," Jaune began, his nervousness tempered by the odd normality of the question, "I like spending time with my friends. I read a bit, and I cook sometimes. I'm not bad at it."

"Cooking," Crayiel echoed, her expression remaining impassive. "A skill often overlooked yet fundamental. A human who can do that for the purpose of sustenance rather than war... intriguing." Her gaze lingered on him for a moment before she added, "Your favorite dish?"

Jaune hesitated, trying to gauge her intentions. "Grilled cheese sandwiches," he admitted with a sheepish shrug. "Simple, but they're the best. I'm not really a fan of pancakes, though."

A faint flicker of something crossed her face—perhaps amusement, though it was gone before he could be sure. "A practical preference," she said. "Pancakes are often overly sweet and lack the structural integrity of true sustenance. A curious creature, you are."

Jaune wasn't sure if he should feel flattered or insulted, so he settled for moving a pawn forward on the chessboard.

Crayiel responded with a calculated move of her own, her hand gliding across the table with an elegance that seemed inhuman. "And what," she said, her tone shifting subtly, "brought you to my family's castle?"

Jaune froze for a moment, his mind racing. He forced himself to meet her gaze, knowing hesitation could easily be mistaken for deceit. "A friend brought us here," he explained carefully. "We came with a demon who specializes in dimensional transfers. It was supposed to be a quick visit—just to see her home—but something went wrong. My group got separated, and I ended up here with two others. I don't know what happened to the rest."

Crayiel studied him in silence, her sapphire eyes piercing. Jaune could almost feel the weight of her scrutiny, and he hastily suppressed the thought of mentioning Ruby. If she's Leviathan the III, like she said, better not to mention that he is a friend of Belphegor the III.

"And yet you survive," Crayiel said finally. "Fate's currents are fickle. Perhaps there is a reason you were swept into our domain."

The game continued, with Jaune focusing intently on the board. Despite his nerves, he found himself gaining the upper hand, his pieces gradually boxing her into a corner. Crayiel's expression remained unreadable, but Jaune thought he detected a faint flicker of frustration when he moved his queen into position.

"Checkmate," he said cautiously.

Crayiel stared at the board for a long moment, her fingers resting lightly on her lap. Then, to Jaune's surprise, she leaned back slightly in her chair. "You've won," she acknowledged, her voice as calm as ever.

Jaune exhaled a breath of relief, a small smile forming on his lips. "That was… actually kind of fun. But I should get going. My friends are probably—"

He stopped mid-sentence as Crayiel's arm transformed in an instant. Her pale skin reshaping itself into a massive crab claw, its surface a mottled purplish-white, polished and lethal. Before he could react, the claw shot forward, gripping his neck with surprising restraint but unmistakable power.

"I could decapitate you now," Crayiel said, her tone almost conversational. Her sapphire eyes locked onto his, and for the first time, there was a spark of something deeper—a quiet satisfaction, perhaps, or the faintest trace of amusement. "But I find myself… entertained. I do not wish for this to end so quickly."

The claw tightened slightly, enough to make Jaune's breath hitch. "Another game," she declared, her voice unyielding. "You have captured my interest, Jaune Arc. And I trust you can imagine the consequences should you refuse."

Jaune's face turned pale as he nodded frantically, his thoughts racing. "Definitely in trouble. Definitely, definitely in trouble."

Crayiel released him, her claw retracting into its human form as smoothly as it had appeared. She gestured to the chessboard with an almost lazy elegance. "Reset the pieces," she said, her tone carrying the faintest hint of satisfaction. "Let us begin again."

Jaune swallowed hard, his hands shaking slightly as he started rearranging the board. "So much for escaping."

(…)

Nora staggered slightly, her breaths coming in short, labored gasps. Her body was battered—bruises blooming across her arms and legs, and a thin trickle of blood ran down the side of her temple. Despite the toll the fight had taken on her, her grin remained undiminished, even as her muscles screamed in protest.

"This bastard," she muttered under her breath, shifting her stance. Her fists trembled slightly as she raised them again, ready for whatever might come next. "He's got way more endurance than I thought." She chuckled, the sound tinged with both exhaustion and exhilaration. "Tch, I think I'm gonna lose this one."

Her grin widened, her eyes sparkling with the thrill of battle. She rolled her shoulders, ignoring the pain that shot through her. "Fights this exciting don't happen every day. So what if I lose?"

The thought of defeat—of death—barely crossed her mind. She was no stranger to threats, having grown up in streets ruled by gangs and petty criminals, their promises of violence as empty as their courage when faced with her fists. The weight of her current predicament seemed far removed from her carefree demeanor.

Nahtaivel loomed before her, unscathed save for a few superficial dents in his armor-like hide. His glowing yellow eyes locked onto hers with cold precision, his lips curling into a sneer. The air between them crackled with tension as he raised a massive claw, preparing to deliver the finishing blow.

Before he could strike, a commanding voice rang out from behind him, cutting through the charged atmosphere.

"That's enough, Nahtaivel."

The demon froze mid-motion, his hulking frame stiffening as though an invisible force had bound him. Slowly, he turned to face the source of the voice, his expression shifting from menace to deference. Upon seeing who had spoken, Nahtaivel immediately dropped to one knee, bowing his massive head.

"Young master," Nahtaivel rumbled, his voice filled with reverence. "Forgive me for the disturbance. I was about to eliminate this intruder."

Nora blinked in surprise, lowering her guard slightly as her gaze shifted to the newcomer.

A young man stepped into view, his presence commanding yet oddly relaxed. He appeared to be in his late teens, his tan skin glowing faintly in the dim light of the corridor. His striking blue eyes carried an air of sharp intelligence, though they also seemed to sparkle with a hint of mischief. His light-blue hair was styled into a messy undercut, strands falling carelessly across his forehead.

His attire was both regal and practical. A deep navy-blue coat, embroidered with intricate silver patterns resembling ocean waves, swept down to his knees. The coat was tailored to perfection, its high collar adorned with small silver clasps shaped like seashells. Beneath it, he wore a fitted white shirt with ruffled cuffs that peeked out from the ends of his sleeves. A wide black belt with a silver buckle cinched the coat at his waist, and slim black trousers tucked neatly into polished knee-high boots completed the ensemble. Around his neck hung a pendant—a sapphire encased in a swirling silver design that seemed to shimmer with an otherworldly light.

The young man's expression was calm but firm as he addressed the demon. "Go to the vault," he ordered, his tone leaving no room for argument. "Ensure that the treasures of the royal family remain secure. I will handle this."

Nahtaivel rose swiftly, towering over the young man even as he inclined his head respectfully. "As you command, young master." Without another word, the demon turned and lumbered down a nearby corridor, his heavy footsteps echoing through the hall until they faded into the distance.

Nora remained silent, watching the demon retreat with a mixture of curiosity and regret. She shifted her weight onto her uninjured leg, letting out a low whistle.

"Pity we couldn't finish that fight," she said, half to herself. Her grin didn't waver, though it took on a rueful edge. "I probably would've lost, but still, it was fun while it lasted."

The young man's sharp blue eyes lingered on Nora for a moment, a faint smile tugging at his lips. He inclined his head slightly, offering a graceful bow with a flourish of his hand.

"It is an honor to meet a woman as beautiful as you," he said smoothly, his voice warm and polished. "I am Neptune Vasilias, also known as Leviathan the IV—a member of the royal family that governs this kingdom. And may I have the pleasure of knowing your name?"

Nora blinked, caught off guard by the unexpected compliment. For a brief moment, her expression shifted from surprise to her usual playful confidence. Crossing her arms, she cocked her head to the side with a lopsided grin.

"Huh, I don't get compliments like that very often," she admitted. "But if you think you can flirt with me that easily, you're wrong. You'd have to show me your strength first." She jabbed a thumb at herself, ignoring the ache in her muscles. "Name's Nora. Nora Valkyrie."

Neptune's smile widened at her response, a glimmer of amusement dancing in his eyes. "Beautiful and brimming with strength," he said, his tone carrying a hint of admiration. "You're truly remarkable, Nora. I would love for you to become my contractor someday, but I suppose that's a conversation for another time."

Before Nora could retort, Neptune continued, his expression softening slightly as he spoke. "In any case, now that I've heard your name, I know you must be one of Ruby's friends."

At the mention of Ruby, Nora's face lit up with recognition. "Oh, Yang's little sister! You know her too?"

Neptune's gaze shifted toward a nearby window, where the light of the distant ocean depths filtered through the ornate glass. He smiled faintly, though his expression carried a weight of nostalgia.

"Ruby and I are old friends, you could say," he replied, his voice quieter now. "She called me not long ago, worried about some of her friends who went missing in our kingdom. I suspected the commotion in the castle might be related, and it seems I was right." He turned back to Nora, his demeanor regaining its earlier focus. "She gave me descriptions and names. Now it seems we're only missing two more: someone named Jaune and a demon called Ciel."

Nora's brow furrowed as she recalled the chaotic events that unfolded when they first arrived. "Eh, if I remember right, that Ciel person seemed like she was up to something. She drew the guards' attention as soon as we got here."

Neptune's expression darkened slightly, the corners of his mouth tightening. "Huh. Ruby has always been far too trusting," he murmured, more to himself than to Nora. "It's entirely possible that this demon, Ciel, was responsible for the situation that led you all here."

He straightened, his serious demeanor returning as he clasped his hands behind his back. "In any case, Nahtaivel should be more than capable of guarding the castle's treasures for now. Our priority is finding your blonde friend. If Ruby's descriptions were accurate, he's not exactly the fighting type. He could very well be in grave danger."

Nora nodded, her earlier fatigue momentarily forgotten. "Yeah, Jauney's not much of a fighter, but he's smart. We'll find him."

(…)

Jaune sat across from Crayiel, his fingers idly toying with a captured rook as he tried not to let his thoughts wander too obviously. "This is the tenth game. Ten games, and I've won every single one. Now that I think about it, she doesn't seem to have anyone else to play with. It makes sense… she's awful at chess." Of course, Jaune had no intention of saying that aloud.

Crayiel moved a bishop, her gaze fixed on him with that same unnerving intensity. "Seven sisters," she said, her tone tinged with incredulity. "It's incredible your family is so large. I, on the other hand, have only a younger brother—and I find him insufferable. My elder sister died long ago, so I am left to contend with a single irritation."

Jaune shifted his queen into position and studied her expression. As always, it remained unreadable, but within moments, her eyes flickered toward the board, and he saw the realization dawn.

"Checkmate," he said cautiously.

Crayiel stared at the board in silence, her hands resting lightly on the edge of the table. Slowly, she leaned back, her movements deliberate and measured. Without a word, she began resetting the pieces, her porcelain fingers moving with a practiced elegance.

"I'm going to run out of things to talk about at this rate" Jaune thought, watching her. "I need to get out of here. Hmm… maybe I can try something."

As she finished arranging the last of the pawns, Jaune cleared his throat. "Uh, I don't mean to interrupt, but… I'm starving. Any chance you could get me something to eat? If you want me to keep entertaining you, I'll need some fuel."

Crayiel paused, her hands hovering over the board. She seemed to consider his words carefully, her sapphire eyes narrowing slightly. "Huh. You're correct. A proper owner should ensure the well-being of their possessions."

Jaune decided to let that comment slide, focusing instead on the opportunity her departure might offer.

Crayiel rose gracefully, her movements as fluid as a predator stalking its prey. She approached the heavy door of the room, her steps echoing softly against the stone floor. "I will fetch something for you. But listen closely, Jaune Arc," she said, her voice cold and unyielding. "You will wait here. If you are not present when I return, the consequences will be far worse than anything you can imagine."

With that ominous warning, she opened the door and disappeared into the shadowed hall beyond, leaving Jaune alone.

The moment the door clicked shut, Jaune sprang to his feet, his heart pounding. "Yeah, I think I'll take my chances," he muttered under his breath. "She thinks I'm her possession? Not a great sign."

He bolted from the room, his footsteps muffled against the thick carpets as he navigated the castle's winding corridors. He was focused on finding Nora—or anyone, really—who could help him escape.

As he sprinted through a vast hall, a deafening crash shattered the eerie silence. He skidded to a halt as a monstrous creature burst through the nearest wall, sending shards of stone and crystal scattering across the floor. The beast sprawled on the ground, its massive form heaving as it struggled to rise.

Jaune's breath caught in his throat. Before he could react, a figure stepped through the gaping hole in the wall. Jaune's heart sank as he recognized her. "Ciel?"

The woman turned at the sound of her name, her expression cold and unreadable at first. But then, a sly smile spread across her face, sharp and unsettling. Her pristine white coat was gone, she seemed completely unscathed.

"So," she said, her voice dripping with amusement, "you're still alive."

Jaune's stomach churned at the glint in her eyes.

"I should kill you," she continued, almost idly. "But you and that other human have proven to be far better distractions than I anticipated. So, consider this your lucky day."

Her smile widened, and she extended her hand, revealing a strange, glowing green stone resting on her palm. Then, in a disturbingly casual motion, she lifted it to her lips and placed it on her tongue.

"Goodbye, Jaune Arc," she said, her voice laced with mockery. "With any luck, we'll never meet again."

As she spoke, a circle of intricate runes appeared beneath her feet, glowing with an intense green light. Jaune shielded his eyes as a pillar of light engulfed her, the force of it sending a rush of wind through the room. When the light faded, she was gone—vanished without a trace.

Jaune lowered his arm slowly, staring at the spot where she had stood just moments ago. His voice came out barely above a whisper.

"What the hell just happened?"

The demon Nathaivel groaned as he pushed himself off the rubble, his massive form trembling with barely restrained fury. His eyes burned with hatred as he slammed a clawed hand into the ground. "Damn it! That wretched woman stole one of the royal family's treasures!"

His gaze shifted to Jaune, who was still frozen in place, his heart pounding against his ribs. Nathaivel's scowl deepened, his expression twisting with murderous intent. "And you—another filthy intruder! I won't let a single one of you escape. I'll tear you apart!"

Jaune stumbled back, his voice caught in his throat as the demon charged. The first strike barely missed, the force of the blow shattering the floor where Jaune had stood mere seconds before. He dodged the second by sheer luck, diving to the side as the monster's claws raked through the air.

Panic overtook him as he scrambled to his feet, only to trip over a loose piece of debris. He hit the ground hard, wincing in pain as he looked up to see Nathaivel towering over him, a sadistic grin spreading across the demon's grotesque face.

"You're mine, human!" Nathaivel bellowed, raising his massive arms to crush Jaune like an insect.

Jaune's breath hitched as he closed his eyes, bracing for the end. But the blow never came. Instead, a deafening crash echoed through the hall as Nathaivel's enormous body was hurled backward, skidding across the floor like a discarded doll.

A cold, commanding voice rang out. "Do not touch what belongs to me, Nathaivel. You are a mere servant."

Jaune's eyes flew open, and his blood ran cold. Standing at the far end of the corridor was Crayiel, her sapphire eyes gleaming with deadly intent. Her right arm had transformed into a massive crab claw, its jagged edges glinting menacingly in the dim light. It didn't take much imagination to realize she had been the one to send Nathaivel flying.

Nathaivel scrambled to his knees, his face pale with terror. He bowed his head so low it nearly touched the ground. "M-my apologies, Lady Crayiel," he stammered. "I did not know the human was yours."

Jaune, on the other hand, felt every muscle in his body lock up as his gaze flicked between the enormous demon and Crayiel. His voice cracked as he forced out a nervous laugh. "Oh, uh… hey, Crayiel. I just, uh, needed to use the bathroom! Heheh…"

Crayiel began to stride toward him, her claw clicking open and shut with deliberate menace. Jaune's hair stood on end as a wave of killing intent rolled off her.

"I warned you what would happen if I didn't find you in my chambers," she said, her voice as cold as a frozen blade. "I won't kill you… but you don't need your legs to entertain me."

Her words sent ice through his veins. The sight of her claw snapping open and shut in a calculated rhythm made him break out in a cold sweat. Jaune wanted to move, to run, but his legs refused to obey.

Just as Crayiel loomed closer, her brother's voice cut through the tense air. "Stop, Crayiel."

The clicking of the claw halted as Crayiel turned her head, her gaze falling on the figure standing beside Nathaivel. Neptune stood tall, his expression calm but unyielding, with a confident air about him. Beside him was Nora, who looked worse for wear but unbothered, a faint grin tugging at her lips.

Crayiel's sapphire eyes narrowed. "Neptune, don't interfere. This human is my possession. I intend to discipline him, nothing more. And I assure you, I don't plan to kill him. I…think i like him."

Nora darted forward, throwing her arms around Jaune in a cheerful embrace. "Heheh, good to see you're still alive, Jauney! Though you were definitely in trouble, huh?"

The warmth of her energy pulled Jaune out of his terror, and he found his voice again. "Somehow, yeah, I'm still alive. But, Nora, you look awful! What happened to you?"

Nora pulled back with a sheepish grin, gesturing to the massive demon still kneeling on the floor. "Oh, I fought that big guy. It was pretty fun, but Neptune stopped the fight."

Jaune's attention shifted to Neptune, his curiosity piqued. "Who… who exactly is he?"

Nathaivel, clearly irritated, answered in a sharp tone. "Show some respect, human. That is Neptune Vasilias, or Leviathan the IV, the future Demon Lord."

Jaune's eyes widened in shock. "So… they're siblings."

Nora beamed at him. "And guess what? Neptune's a friend of Ruby's! He said he can help us get out of here."

Relief flooded Jaune at those words, but it was short-lived. Crayiel's icy glare and the oppressive wave of bloodlust she exuded snapped him back to reality.

"Move aside, little brother," she said coldly, her voice devoid of affection. "Or I will kill you. I will not repeat myself."

Neptune's voice rang with unwavering authority, his calm demeanor a sharp contrast to the chaos around him. "Nathaivel, take the humans to my chambers. There's a dimensional transfer stone there—it should get them out of here. I'll handle my sister. Go, now!"

The towering demon snapped to attention, his posture rigid with deference. "As you command, young master!" Without a moment's hesitation, Nathaivel turned sharply toward Jaune and Nora, his voice rumbling with restrained irritation. "You two, move! I'd gladly kill you myself, but the young master's orders are absolute. Follow me!"

Jaune didn't need a second invitation. His survival instincts screaming louder than any thoughts. Nora, however, lingered just a moment, flashing Neptune a grin brimming with fiery confidence. "Hey! Next time we meet, I want a fight. Don't die before then!"

Neptune allowed himself a faint, knowing smile at her audacity, though his focus remained firmly on the figure before him.

Nora spun and darted after Jaune, her laughter echoing faintly as the two humans disappeared into the shadows of the corridor. Their retreat left an uneasy silence hanging in the air, broken only by the faint, rhythmic clicking of Crayiel's claw.

She tilted her head slightly, her piercing sapphire eyes studying her brother with unsettling intensity. At his words, however, her expression shifted.

"Crayiel," Neptune said firmly, his tone calm but laced with warning. "Those humans are friends of Ruby. I can't let you harm them."

For a moment, the revelation seemed to catch her off guard. Her eyes widened slightly, but the surprise was fleeting. It melted into a chilling, predatory smile, one that sent a shiver through the stagnant air.

"So… Jaune is a friend of Ruby," she murmured, her voice laced with a quiet malice that made the hairs on Neptune's neck stand on end. A low, unsettling chuckle escaped her lips. "Heheheh. That only makes me want him more." Her porcelain features twisted into something almost feral, a dangerous glint sparking in her gaze. "You know how I loathe Belphegor the III. The very thought of her makes my skin crawl. To take something precious from her… to see her stripped of her smug little grin… Oh, how sweet that would be."

Her other arm began to shift, flesh twisting grotesquely until it hardened into a second massive claw. The transformation was seamless, unnervingly fluid, and the air around her seemed to hum with the weight of her barely restrained power.

Neptune remained unshaken, though his expression darkened slightly. "Crayiel, you're not thinking straight. You know as well as I do that if we fight at full strength, we'll destroy the castle. And if that happens, Father will kill us both without hesitation."

Crayiel regarded him with her usual vacant, icy stare, her lips twitching into a faint smirk. "Jaune Arc is the first human I've ever encountered," she said, her tone devoid of warmth but heavy with obsession. "And I liked him. He entertained me. Amused me. When I like something, I acquire it." Her words were measured, calm, but beneath the surface simmered an unyielding fixation. "I don't care if there are millions of other humans. He is the only one that interests me. And knowing he belongs to Belphegor the III… that only makes him more desirable."

She paused, her claws clicking ominously in the silence. "But you have a point. Destroying the castle would anger Father. I suppose… fighting at half strength will suffice."

Neptune sighed, a weary exhale that spoke of his endless patience being tested. He ran a hand through his hair, his gaze unwavering. "You're impossible, sister. Absolutely impossible." His lips twitched into a faint, resigned smirk. "Ruby's going to owe me big for this."

(…)

Nathaivel thundered down the corridor, his colossal footsteps reverberating through the stone halls. Behind him, the castle quaked violently, the fierce battle between Neptune and Crayiel shaking its very foundations. The air was thick with tension, the echoes of their clash growing louder with each passing second.

When the trio reached a massive iron-bound door, Nathaivel skidded to a halt, spinning to face them. His eyes blazed like molten fire, and his voice was a guttural roar of command. "Inside! Use the stone and get out of here immediately! Think of the place you wish to go, and it will take you there. Hurry, while the young master holds her back!"

Jaune and Nora hesitated for a heartbeat before rushing inside, the urgency in Nathaivel's voice leaving no room for argument.

Dominating the center of the room was an imposing bed, its frame crafted from blackened steel veined with shimmering streaks of silver. The canopy above was a translucent fabric that rippled like the surface of a tranquil sea, creating a serene, hypnotic effect. Nearby, a large, intricately carved desk overflowed with aged tomes, parchment scrolls, and peculiar devices.

It was on this desk that Jaune's eyes fell upon a small, luminous green stone. The glow was unmistakable, a steady pulse that seemed to beckon him. His heart leapt in recognition. "It looks like the stone Ciel had, so this is a dimensional transfer stone."

A violent tremor shook the room, and the sound of shattering stone made Jaune flinch. The furious battle was drawing closer. His chest tightened with panic.

"Nora!" He shouted, his voice cracking. "Quick—give me your hand!"

Nora darted to his side without hesitation, her usual carefree demeanor replaced by a sharp focus. She grasped his hand tightly, her grip steady.

As Jaune wrapped his fingers around the glowing stone, Nora's voice broke through the rising tension. "Hey, Jauney, don't forget what the big guy said. Think of a place—your house, maybe? That could work!"

Jaune swallowed hard, closing his eyes. "Home," he thought desperately. "Take us home."

The stone flared to life, its glow intensifying until the entire room was bathed in brilliant green light. In an instant, a radiant pillar engulfed them, the energy swirling around like a protective cocoon. The sensation was both exhilarating and terrifying—weightlessness combined with a rush of warmth.

When the light finally subsided, Jaune collapsed onto familiar floors. He blinked rapidly, his eyes adjusting to the dim, cozy interior of his family's house.

They had made it. They were safe.

Greetings, I take this opportunity to wish everyone a Merry Christmas, this chapter took me longer than I thought and I had to modify some things but I think it turned out well in the end, I really appreciate the reviews, I will probably publish one more chapter before the new year. And now I take the opportunity to respond to some reviews:

IRA Aston Impereticus: well Jaune won't stay away from Yang because he's a good guy and she's her best friend, he'll help her however he can, although right now he's not strong, he's the smartest human for now, about the other thing, I'm not sure if I'll include angels in this story, it is possible but it depends on how far I go in this story.

Guest1: Ren will appear in the next arc of this story.

Guest2: Thanks for the review and yes, Jaune has that talent of attracting dangerous women, sometimes it's a good thing but most of the time it will be bad. As for breaking the fourth wall, don't worry, only Deery and Jaune on rare occasions will do that.
