The Summer Solstice. The grand summertime convocation of the Greek gods of Olympus, held but once a year, a sacred day when their divine powers reach their zenith. It was a day of utmost importance for the deities, a day steeped in ritual and strategy.

As for Percy Jackson, it should have been just another ordinary day.

Keywords: Should have.

He fought the urge to sigh as he stood amidst the colossal forms of the Olympian gods, who bickered furiously in ancient Greek, voices echoing like thunder through the grand Hall of Gods. Though the language was foreign to him, Percy knew precisely what had stirred up such chaos.

He had been the one to deliver the news—the grim tidings of Kronos, his grandfather, on the brink of awakening once more.

The Olympians debated fiercely, their divine powers crackling in the air like an impending storm, but all Percy wanted was to be anywhere but here. Fatigue from his recent quest to recover the Master Bolt weighed heavily on him, his body aching for rest. His mind drifted to Annabeth and Grover; he couldn't help but worry if they had made it back to camp safely.

With another sigh, he wished silently, fervently, to be dismissed and allowed to leave this place of tension and divine politics.

"Is that what you wish for, Percy? To leave this place?" The voice came out of nowhere—smooth, resonant, and carrying a weight that made Percy shiver. Before he could even locate the source, the voice continued, "I could grant that wish… but I'm afraid I'll need you to stay a bit longer."

Instinct took over, and Percy spun around, eyes wide. "Who said that?!"

His outburst silenced the hall, the gods ceasing their argument to turn their gazes toward him. It was as if he had just declared war; they stared at him with a mixture of confusion and irritation.

"Percy?" Poseidon's deep voice broke the silence, tinged with paternal concern. "Are you alright, my son?"

Percy flushed, suddenly aware of all the divine eyes fixed upon him. "Sorry," he mumbled, rubbing the back of his neck sheepishly. "I thought I heard someone talking to me, but I don't see anyone."

The Olympians exchanged wary glances, puzzled. There shouldn't have been anyone else in the hall—at least, that's what they believed.

"If you're searching for me, I'm right here," the mysterious voice spoke again, amused.

All heads snapped up, and the collective breath of gods and demigod alike was drawn in sharply. There, floating cross-legged above them as if seated upon invisible air, was a figure entirely unlike any they had ever seen.

He looked young, no older than a mortal in his late teens, yet there was an agelessness about him, a timeless quality that transcended mere youth. His skin was pale, almost ethereal, as if carved from moonlight itself, and his hair was a wild mane of silver that seemed to shimmer with its own inner light. From his forehead sprouted two small, horn-like protrusions, lending him a distinctly otherworldly appearance. He wore flowing black garments beneath a long, white robe adorned with arcane symbols and patterns, the likes of which none of the gods recognized.

Behind him hovered ten pitch-black orbs, perfectly aligned in a circle, as though they were celestial bodies in orbit. In his right hand, he held a black Shakujō, a staff ringed with delicate chimes that seemed to sing a song of the cosmos.

But it was his eyes that struck the gods with the deepest unease—one was metallic silver, rippling like the surface of a still pond disturbed by a single drop of rain. The other was a blood-red eye with nine tomoe encircling its center, the pattern spiraling inward like the gaze of infinity itself. Yet, what was most unsettling was the sheer absence of presence. Though they could see him clearly, it felt as if he wasn't truly there, like he was merely an illusion formed from shadows and mist.

The enigmatic figure offered Percy a warm, almost playful smile. "Hello, Percy."

Percy, caught entirely off-guard, could only blink. "You… you sound like you know me. Who are you? Are you an alien or something?"

The man's expression shifted, his eyes widening before he erupted into laughter—loud, hearty, and entirely at odds with the tension in the room. The gods watched, their wariness intensifying, as if they were observing a dangerous predator toying with its prey.

Still chuckling, the man wiped a tear from his eye. "Me, an alien? That's priceless!" He shook his head, the laughter subsiding into a soft chuckle. "No, Percy, I'm not an alien."

"Oh," Percy replied, feeling heat rise to his cheeks. "That was probably a stupid question."

"Not at all," the man reassured him with a kind smile. "I once asked something quite similar myself." He turned his gaze to the gods, who now eyed him with open suspicion, their divine power simmering just beneath the surface, ready to strike.

The man raised a hand, palm out, as if to placate them. "I understand you're all curious about who I am," he began calmly, "and I'll answer your questions. But first, there's someone else who needs to be here."

With a simple snap of his fingers, the very fabric of reality seemed to warp, and Hades appeared, looking both bewildered and indignant.

"What in the name of Tartarus…?" Hades muttered, glancing around the hall before his dark eyes settled on Percy. "Perseus?"

"Uncle Hades!" Percy exclaimed, stepping forward. "What happened to my mom?!"

Hades regarded him silently for a moment, then sighed. "She's safe. I returned her as thanks for recovering my helm."

Percy hesitated, searching his uncle's face for any sign of deceit, but found none. Poseidon stepped closer, placing a reassuring hand on his son's shoulder. "You can trust him, Percy. Hades may be many things, but he's honorable."

Before Percy could respond, Zeus's voice boomed, the Master Bolt slamming into the floor with a crack like thunder. "Hades! You know you are not permitted here! Explain yourself!"

Hades scowled, his gaze hardening. "I didn't come here by choice, Zeus. One moment I was in my realm, the next I was summoned here."

"Enough!" The mysterious man's voice cut through the tension like a blade, his tone light yet commanding. He clapped his hands together. "I brought him here. We need him for what I'm about to say."

Zeus narrowed his eyes, his suspicions deepening. "And why would you do that?"

The man's smile returned, serene yet cryptic. "I said I have a reason for being here, and it involves all of you. Hades needed to hear this as well."

The gods glanced at one another, uncertain. It was Athena who stepped forward, her gray eyes piercing, calculating. "Very well. Start with your name."

"Naruto," the man replied, flashing a grin that seemed to light up the room.

Athena raised an eyebrow. "And why have we never heard of you before?"

Naruto's grin widened into a mischievous smirk. "Who's to say you haven't? Perhaps it's my brother you've heard whispers of."

"Your brother?" Artemis asked, stepping forward, her silver eyes narrowed with suspicion. "And who might that be?"

Naruto chuckled, the sound rich with hidden amusement. "My brother is the primordial aspect of Chaos."

A stunned silence fell over the hall. The very air seemed to freeze as the gods processed his words.

"That's impossible," Athena whispered, shaking her head. "Chaos isn't a person—it's the origin of everything."

Naruto sighed, a look of fond exasperation crossing his face. "You've got it wrong. He's very much alive… and a pain in the ass."

"If that's true," Athena began, her voice sharp and laden with skepticism, "then you, who claim to be the brother of Chaos—who exactly are you?"

Naruto tilted his head slightly, a playful smile curling at the corners of his lips, as though he were amused by her question. He didn't answer immediately, savoring the suspense that hung heavy in the air like a gathering storm cloud. "Come now, Athena," he said finally, his voice a melodic blend of amusement and challenge. "You've already pieced it together, haven't you?"

Athena's gray eyes narrowed. Despite her misgivings, she knew he was right. She had already formed a theory, and though it seemed impossible, the evidence stood before her in all its otherworldly glory. "But I suppose I can indulge you," Naruto continued, looking down at the assembled Olympians and their mortal champion, his gaze sweeping over them like a caress from the cold hand of the void.

He spread his arms wide, the staff in his right hand gleaming with an unearthly sheen as it caught the light. "I am the origin of all life and energy. The architect of law and the harbinger of peace. The Sustainer. The Enforcer." His voice grew deeper, each word vibrating through the room, sinking into their very bones. "I am—OOOH!"

The sudden cry of surprise interrupted the grandiose speech, as Naruto was unceremoniously kicked from behind, sending him sprawling forward in an undignified tumble.

"That introduction was way too long!" a new voice interjected, dry and biting, laden with sarcasm.

Every eye turned towards the figure who had delivered the kick, and the gods collectively tensed once more. Standing above Naruto, who was now face-down on the polished marble floor, was a man who looked like a dark reflection—a mirror image, but inverted in every way.

This man had the same chalk-pale skin, devoid of any blemishes or marks, save for the notable absence of Naruto's whisker-like scars. His hair, unlike Naruto's wild silver mane, was a deep, inky black, darker than the void between the stars. He wore a robe similar in style but opposite in color: where Naruto's was a radiant white, his was an abyssal black with a white interior. The magatama patterns were identical, yet they seemed to pulse with a different energy, one that felt like the echo of a silent scream lost in the void.

The gods felt a wave of primal fear course through them, instinctive and uncontrollable, as they locked eyes with this new arrival. He had the same mismatched eyes as Naruto, but reversed—the metallic silver eye was on his right, and the blood-red, tomoe-filled eye was on his left. The same ten black orbs hovered behind him, and in his left hand, he wielded a Shakujō with a crescent-shaped top, its dark rings clinking softly, like the chime of a funeral bell.

The man's lips twisted into a smirk as he looked down at Naruto with an expression that could only be described as smug satisfaction. "Naruto," he drawled, his voice dripping with mockery, "you never change, do you?"

Naruto groaned, pushing himself up from the ground with a scowl. "You could have waited, Sasuke!" he snapped, rubbing the back of his head. "You didn't have to kick me!"

Sasuke's smirk only widened, a glint of dark amusement in his mismatched eyes. "Oh, but I did. I wasn't about to let you drone on like the Rikudō Sage." He turned his attention to the gods, who were still frozen in stunned silence, and his expression shifted to one of mild disdain. "The name is Sasuke. Though you lot might know me better as… Chaos."

The Olympians, who had thought they could no longer be shocked, found themselves swallowing hard. The reality of the situation sank in like a stone plunging into deep water. This wasn't a mere boast. They could feel the truth in his words, in the oppressive weight of his presence.

Athena, ever the rational thinker, struggled to reconcile what she was witnessing. "But that would mean…"

"That this one over here," Sasuke interrupted, jerking his thumb at Naruto with a smirk, "is Order."

Naruto shot to his feet, glaring daggers at his counterpart. "The only thing unimportant here," he growled, his eyebrow twitching violently, "is your attitude!" In a blur of movement, Naruto appeared right behind Sasuke, his leg raised high. "IS YOUR ASS!" he shouted as he brought his foot down, kicking Sasuke squarely in the rear and sending him crashing into the floor with a resounding thud.

Sasuke rebounded quickly, flipping back to his feet and narrowing his eyes at Naruto, his expression one of pure irritation. "You bastard!" he snarled, swinging his staff in a wide arc. Naruto met the attack with his own staff, the chimes clashing in a discordant symphony of sound that resonated through the hall like the tolling of a cosmic bell.

The two clashed again and again, moving with a speed and fluidity that left even the gods struggling to follow their motions. Sparks of golden and black energy crackled and sizzled with each strike, creating a swirling vortex of light and shadow around them.

Meanwhile, the Olympians and Percy sweatdropped, watching the scene unfold like a bizarre, divine comedy. Artemis turned to her sister, rubbing the bridge of her flawless nose in exasperation. "Is it just me, or are all male deities complete morons?"

The affronted grumbling of the gods echoed in the background, but Artemis ignored them. Athena, standing beside her, gave a thoughtful nod. "I have a theory about that," she said, her voice laced with dry humor as she continued to analyze the scene. "Given the sheer amount of power they possess, it's possible their bodies had to develop accordingly to contain it all. As a result, there wasn't much left for brain development."

Artemis raised an eyebrow, surprised by Athena's rather uncharacteristic jest, but she couldn't help the small smile that tugged at her lips. "That… actually makes sense," she conceded, glancing over at Apollo, who was sitting on his throne munching on popcorn alongside Hermes. "It would explain a lot of Apollo's behavior, that's for sure."

Back in the fray, Naruto landed a solid punch to Sasuke's face, sending him skidding back across the floor. Sasuke's lips curled into a smirk even as he wiped a thin trickle of blood from his mouth. "Is that all you've got, Naruto?" he taunted.

Naruto's grin was wide and feral. "I'm just getting started!"

Before they could launch into another round of their cosmic brawl, a voice cut through the air like a blade of reason amidst the chaos.

"Uh… not to interrupt or anything," Percy called out, sounding equal parts exasperated and impressed, "but weren't you guys here for a reason?"

The Olympians turned as one to stare at Percy, a new sense of respect dawning in their eyes—even Ares had to admit, if only silently, that the kid had guts. It wasn't every day a mortal interrupted two primordial forces mid-fight.

Naruto straightened, letting out a sheepish laugh. "Oh, yeah! I got a little carried away." He stepped forward, clapping Percy on the shoulder so hard that the demigod nearly stumbled. "Thanks for reminding me, kid!"

He turned back to Sasuke, who had reappeared beside him with an eye roll. "Let's get to the point then, shall we?"

"Yes," Sasuke agreed, his voice as cold and unyielding as the void. "It's time they understand why we're really here."

Together, they raised their staves and slammed them into the ground. The hall dissolved in a flash of brilliant light, and in the blink of an eye, the gods found themselves suspended in the vastness of space, floating high above the Earth.

The stars glittered around them like a sea of ancient jewels, their cold light bathing the assembly in a spectral glow. Even the most seasoned Olympians, who had seen countless wonders, could only stare in awe at the cosmic vista unfurling before their eyes.

They found themselves enveloped in a transparent, shimmering barrier, shielding them from the icy vacuum of space. Around them, celestial bodies floated majestically—planets, moons, and the blinding brilliance of the sun itself. It was as if they had stepped beyond the veil of the sky, into the true universe that lay hidden from mortal sight.

"What… is this place?" Athena breathed, her normally sharp, calculating voice softened by genuine wonder.

"This is space," Naruto answered with a gentle smile, his tone devoid of its earlier playfulness. There was a quiet reverence in his voice, as though he were showing them something sacred. "The true universe, beyond the dome of the sky that you know."

Artemis, her silver eyes wide with childlike awe, looked around as if seeing the heavens for the first time. "The moon…" she whispered, her gaze locking onto the celestial orb that hung in the shadows of the Earth. "Is that really…?"

Naruto's smile softened as he turned to her. "Yes, Artemis. That is the true moon, the very one that orbits your world."

The Moon Goddess blinked, processing his words. "But my chariot…" she began, glancing back at the small, glowing orb she held, the manifestation of the moon that mortals saw every night.

"That's just its avatar," Sasuke interjected, his voice cutting through the silence with a cold clarity. He gestured behind them with a casual wave of his hand, drawing their attention to the vast expanse of planets and the radiant sphere of the sun. "The chariots of Apollo and Artemis are merely reflections, avatars designed to move within the boundaries of your world. But the real celestial bodies exist here, beyond the sky's barrier."

Apollo, normally brimming with smug confidence, stood frozen, his golden eyes darting between the sun and the miniature version he held in his hands. "But how…?" he stammered, for once at a loss for words.

"How indeed," Athena murmured, her mind racing as she tried to make sense of it all. "If the sun and moon we know are only avatars, then why is the real sun hidden beyond this… dome?"

Naruto's expression turned somber as he looked out into the infinite void. "It's not a matter of 'why,' but rather a matter of 'how.' The dome of the sky was constructed to isolate your world from the rest of the universe. It serves as a barrier, a shield."

Athena frowned, her brow furrowing in deep thought. "A shield? But from what?"

Sasuke's mismatched eyes narrowed, the silver one gleaming like a polished blade, the red one glowing with a malevolent light. He stared unblinkingly at the moon, half-hidden in the Earth's shadow. "It's time you understand the true reason we brought you here," he said, his voice as cold and dark as the void itself. "Look closely at the moon. It may be shrouded in shadow now, but once it fully emerges…"

He paused, and Naruto joined him, turning to face the assembled Olympians. Their expressions were grave, a stark contrast to the lighthearted banter from earlier. Together, they spoke in a unified, ominous tone that sent shivers down the spines of every god and demigod present.

"…This world will face its end."

A heavy silence fell over the gathered deities, the weight of their words sinking in like lead. Even the mighty Zeus, King of the Gods, found himself at a loss. For a long moment, no one spoke, as if the very stars had paused in their cosmic dance to listen.

"End?" Poseidon finally managed, his voice hoarse, the sea-green of his eyes clouded with disbelief. "What do you mean, the end? Are you saying our world is doomed?"

"Doomed?" Naruto echoed, his lips twisting into a sad, almost regretful smile. "Perhaps. But it doesn't have to be. That's why we're here. To warn you, and to prepare you."

"To prepare us?" Zeus thundered, his eyes flashing with lightning, barely-contained fury simmering beneath his calm facade. "Who are you to speak of such things? To presume to warn us?"

Naruto's smile vanished, replaced by a look of stern resolve. He held Zeus's gaze without flinching, the swirling patterns of his eyes seeming to pierce through the King of the Gods' very soul. "I am Order," he declared, his voice ringing with an authority that made even the heavens tremble. "I was there when the universe was born from the primordial chaos. I have shaped the laws that bind reality itself."

Sasuke stepped forward, his dark presence a stark contrast to Naruto's light. "And I am Chaos," he added, his voice low and dangerous. "I am the void from which all things emerge and to which all things return. We are the balance that holds existence together."

The Olympians felt a chill run through them, an ancient fear stirring in their hearts. It was not merely the words these beings spoke, but the power they exuded, the sense of raw, unfiltered cosmic authority that dwarfed even the might of the Olympian Council.

"Then why now?" Athena demanded, her voice cutting through the silence like a blade. "If you are the balance of the universe, why reveal yourselves now? What has changed?"

Naruto and Sasuke shared a glance, a silent conversation passing between them that seemed to span millennia. Finally, it was Naruto who spoke, his tone gentle, almost sorrowful.

"The moon," he said simply, pointing once more to the celestial body that loomed large above them. "It is not just a barren rock, as you believe. It is a prison. And what it contains is beginning to stir."

The gods exchanged uneasy glances, the implications of his words sinking in like the cold touch of the Styx. Artemis, her voice barely above a whisper, asked, "What… is imprisoned within the moon?"

Sasuke's eyes darkened, a flicker of genuine fear passing through his normally impassive gaze. "The one who was sealed away long ago," he answered, his voice barely more than a breath. "The one who sought to consume everything and remake it in her image. The one who was once our equal."

Naruto closed his eyes, as if recalling a distant memory. "Kaguya."

The name echoed in the void, resonating like the toll of a death knell. The gods recoiled as if struck, the very mention of the name sending ripples of dread through their divine forms.

"Kaguya…" Zeus muttered, his expression uncharacteristically shaken. "But that's just a myth, a tale whispered in the dark ages…"

"A myth?" Naruto repeated, opening his eyes, the silver ripples in his left eye gleaming like the surface of a turbulent sea. "No, Zeus. She is very real. And her power is beyond anything you have ever faced."

Sasuke's lips curled into a grim smile. "The eclipse will mark her awakening. When the moon fully emerges from the Earth's shadow, her seal will shatter. And then…"

"…the world will burn," Naruto finished, his voice a whisper carried by the void.

Welcome back to... Irregular Descent. I've decided to take over this story and just do it on my own for now. Thank you.
