The battle between Seo joon and Seo Rin, a clash between two titans among the S rankers , unfolded in a room filled with blood and corpses of both deceased rankers and monsters, set within the haunting, cavernous walls of the supposed to be s rank dungeon that was nothing more than a play ground for seo joon where he could play god. It was not just a contest of power but an expression of their deepest selves, as warriors, as family members and as people shaped by the brutal world they lived in.
The atmosphere was thick with tension, almost suffocating, as the two combatants faced each other. The ground beneath them was cracked and froze, the remnants of countless battles fought and forgotten. Seo joon stood with an air of calm, his usually serene expression now tinged with a dangerous resolve, his slender form poised with the grace of a predator waiting for the right moment to strike. His long, dark hair swayed gently in the air, though there was no breeze to stir it. He held his blade, Dominion, with both hands, his fingers tracing the edge of the blade, almost lovingly. The weapon was no longer just a tool of battle—it had become an extension of himself.
Rin, in contrast, was a whirlwind of raw, tamed energy, so tamed that he doesn'tknow his full potential. His beautiful, organized hair framed his face, his scarred body gleaming with sweat and the anticipation of violence. The ever-present, grin stretched across his face as his eyes locked onto the masked man as he didn'tknow who was behind the mask. He reveled in the thrill of the fight, his cold aura practically radiating off of him. His ??? Blade , which had become more of a symbol of an ice age than a weapon of purpose, rested lazily at his side, waiting for its turn to sing through the air.
The clash began without warning, the sound of their blades meeting echoing through the chamber like the ringing of a bell, loud and harsh. Rin's movements were swift and precise, every strike calculated, each one designed to test the limits of his strength and resolve. Seo Joon, however, was a force of nature, his swings wild and savage but clean, driven by his insatiable hunger for combat due to corruption of his mind. He relished the pressure of Rin's attacks, each one fueling his madness, pushing him to strike harder, faster, more recklessly.
Rin's skills were nothing short of extraordinary. He moved with a fluid grace that belied his years, his attacks both beautiful and deadly. He danced around his dad's brutal strikes, his sword flashing in the air like a serpent striking from the shadows. He wasn't just fighting him— he was learning from his dad. He was pulling at the very core of his being, forcing his dad to confront the darkness inside himself, the part of him that had been honed and sharpened by years of violence and madness. Rin's style was methodical, like a surgeon cutting away the rot. But even he could not ignore the relentless force that was Joon.
Joon, unbothered by the precision of his attacks, laughed wildly. The sound of it was a mixture of madness and exhilaration, a desperate cry for more. He reveled in the fight, his instincts dictating the flow of the battle as he swung his blade with reckless abandon. Every strike was a testament to his sheer power, the weight of each blow enough to shatter mountains. For all his strength, he was a greater match for Rin's mastery. He knew it, felt it deep within his bones— Rin before him was no ordinary opponent, it was his blood after all. He was his equal, in ways he had never imagined.
Then, in a moment that shifted the very atmosphere of the battle, Rin revealed the true extent of her abilities. With a flick of her wrist, ??? Blade transformed into human form. The blade in human form released its full power, unleashing a wave of ice energy so intense that the ground beneath them trembled. The space froze crackled with ice energy as ???'s form shifted.
Seo joon once serene presence becoming an embodiment of bloodlust, his true nature revealed. He was not just a mere space user or a dimension creator —but a force of nature himself, capable of carnage on a scale that few could comprehend.

Rin, sensing the yawning gulf between them, whispered to the ??? Blade. "Assist me… in blade form. Don't let me be powerless here."
The weapon pulsed once, as if in solemn agreement, and its cold presence wrapped around his soul.
Seo Joon answered not with words but with will. He shifted the battlefield itself. Nightfall spread like ink, shadows stretching long and trembling beneath the strain of two titanic auras colliding.
Rin's spirit blazed with the heat of defiance, his breath steady, his gaze unbroken. Across from him, Joon's presence was calm yet suffocating—an ancient sovereign whose aura warped the very threads of space. The air itself bent under him, dense and unsteady, as if time hesitated to move forward without his command.
Steel met space.
The silence shattered. Their blades collided in an eruption of force that shook the cavernous dungeon. Rin, propelled by loss and loyalty, unleashed every fragment of his being—each swing, each surge of ice, a testimony to his humanity's unyielding will.
Joon answered in kind. His blade Dominion carved through reality itself, bending space and phasing effortlessly through Rin's attacks. Where Rin carved with conviction, Joon rewrote the battlefield, each step a reminder that even the laws of existence bent before him.
Rin's blade was more than steel. It was conviction. It rang with the echoes of every burden he carried—his friends, his scars, his ancestor's shadow, and the fragile hope of the future.
But Joon's counters carried the weight of inevitability. Dominion sang with an authority that quivered through reality, as if every strike had been decided long before the battle began.
And yet—Rin pushed.
Every clash carved open cracks in the script, proof that even fate could be challenged by a heart that refused to yield.
For a single suspended breath, the world seemed to hold still. Darkness clung to them. Ice crackled against rifts in space. Father and son stood poised, the battlefield quaking beneath the pressure of their wills.
When their blades finally fell in unison, the world erupted—frost and distortion tearing through the dungeon in a storm of ice and collapsing stars. The clash was not just steel against steel, but hope against destiny, longing against inevitability.
---
The air warped, fractured lines of reality bleeding across the battlefield.
Seo Joon raised Dominion with a casual flick, and space itself screamed. Dimension slashes rippled outward, thin as hair, lethal as gods. They shredded stone, air, and even sound itself.
Rin darted between them, frost trailing his steps like rivers of starlight. One strike cut too close. He whipped his blade upward—and the impossible happened.
The dimension slash froze.
Like glass catching the light, the distortion hung suspended, locked inside a coffin of ice. The air snapped and groaned as frozen space fought against severed space, a stalemate that split the dungeon's foundations.
Then the world twisted.
The battlefield dissolved into black smoke. Rin blinked once and found himself standing somewhere else entirely—an alien void of pale stone, skyless yet infinite.
High above, on a throne sculpted of shifting void, sat Seo Joon. Dominion lay across his knees, humming faintly with power. His crimson eyes glowed like dying stars as his voice carried across the dimension.
"Here," he said, each word heavy as fate itself, "I am God."
The black sun overhead began to fall.
The void quaked as the celestial mass descended, heat consuming everything. Mountains bent. Rivers boiled. The very earth liquefied into molten rivers.
Rin roared, his blade pulsing. Ice surged in frantic waves, freezing the world from the ground up. Frost climbed mountains, spread through rivers, and reached for the burning star above. The black sun shrieked as frost gnawed at its surface.
Step by step, Rin raised his sword, pouring everything into his strike. Veins burst beneath his skin, blood freezing the instant it touched the air. His lungs burned, his heart staggered—but still he pushed.
The sun froze.
Shards of burning ice fractured, suspended in midair, an impossible contradiction—flame and frost entwined. For a heartbeat, the dimension itself seemed to pause, unable to process what had just occurred.
Rin collapsed to one knee, breath ragged, vision darkening at the edges.
Seo Joon appeared before him in a flicker. One moment on his throne, the next standing so close that the heat of Dominion seared Rin's cheek. With no hesitation, the blade pierced forward.
Pain blossomed white. Dominion carved a hole straight through Rin's chest.
His heart shattered.
Rin's body convulsed, life draining in torrents. Seo Joon lifted his blade again, ready to take Rin's head in one clean motion.
But then—his left hand moved.
It clamped over his right wrist, halting the swing mid-air. The mask cracked. Half of it crumbled away, falling to the ground like broken porcelain.
Through the jagged break, Rin saw it.
A tear slid from Seo Joon's revealed eye. Silent. Shining. Human.
"F… father?" Rin's voice was barely a whisper.
His body collapsed. Vision swam. Blood soaked the frozen ground.
And then—the ??? Blade screamed.
It wasn't metal. It wasn't sound. It was grief made manifest, a wail that shook the very marrow of the dimension.
The ??? Blade trembled where it lay, its edge continued screeching like a wounded beast.
Frost erupted
In a shimmer of frostlight, it shifted—slender steel unfolding into the form of a young girl. She fell to her knees beside Rin's fallen body, her small hands pressing desperately against the gaping wound in his chest.
Tears streamed down her pale cheeks, freezing the moment they touched her skin. "Don't leave me," she whispered, her voice breaking as she clung to him. Her fingers traced the hole in his chest, trembling, before pressing into it as though she could shield his heart with her own.
The world stilled.
And then—darkness.
In the hollow of Rin's chest, veins of ice coiled, bones wove together, a heart of crystal forming in the void where his human one had been. The wound sealed, pulsing with new rhythm—cold, eternal, alive.
In his mindscape, Rin stood within a storm of snow. The blade's voice filled it, sharp as a sword-edge yet soft as a whisper.
"I will not lose another father. If flesh betrays you, then I will become your flesh. If your heart fails, I will beat as your heart. From now on—we are one."
"Why… why do you always fight like you want to disappear?" she sobbed, voice raw.
Rin managed a faint smile, lifting a hand to brush the frost-wet strands of hair from her face. His touch was weak, but steady. "Hey… don't cry. I'm still here, aren't I?"
Her lips quivered, eyes wide with grief. "But you're slipping away. I can feel it—"
"No." His voice grew firmer, quiet yet unyielding, like the edge of his blade. "You've carried me this far. You're not losing me. Not now, not ever."
The girl froze, her sobs caught between disbelief and hope.
"You're my partner," Rin whispered, his gaze steady despite the blood trailing down his chin. "If you're still here, then so am I. So… trust me. Calm down. I won't let go."
The trembling in her hands slowed, her tears softening into silence as she pressed her forehead against his. For the first time, the fear in her eyes dimmed—replaced by a fragile, fragile trust.
Rin's eyes snapped open.
Power flooded him, cold as creation itself. His aura towered, stretching to the edges of the void. His form shifted, robes of shimmering frost wrapping around his body, hair streaming white-blue like winter banners. His eyes glowed with a glacial light that pierced through existence.
The Frost Monarch had risen.
Seo Joon froze. For a moment—just a moment—the tear in his eye glimmered, the mask half-broken, the man beneath revealed.
But the Scriptwriter did not allow peace.
Crimson light swallowed his gaze, drowning it in madness. His body stiffened, then convulsed. Dominion howled, space folding in on itself. His aura warped into something grotesque, endless, berserk.
The father's hand fell limp. The sovereign's eyes went dark.
The Scriptwriter had taken full control.
And the real battle had just begun.
Codex Record Update — Frost Monarch Rebirth
Designation: Soul-Fused Entity — Transcendent Tier
Bearer: Seo Rin
Status: Reborn through Symbiosis
> Annotation:
The ??? Blade, long burdened with centuries of grief, has broken the boundary between weapon and master. No longer a tool, no longer merely a partner, it has entwined itself into the very flesh and spirit of its chosen bearer.
Rin's mortal heart ceased to beat. In its place, the blade gave itself—crystal, ice, and will—becoming the eternal rhythm that sustains him. Flesh and steel are indistinguishable now; every breath he draws is mirrored by the pulse of frost that echoes through eternity.
This is not an evolution of power. It is a union, irreversible and absolute. From this moment, Rin and the blade are one: the Sovereign of Eternal Winter, a monarch whose heart is no longer human.
As a result of this fusion, due to the fact that the ??? Blade is Indestructible and immortal, the same applies to Rin's heart and the portion where the hole existed, but it doesn't make him completely immortal, only that he can regenerate.
"My master… my partner… my heart. Until all stars freeze, I shall never let you fall again."
