[Appraisal Activated]
Light burst from Asura's palm — clear, radiant, refracting like crystal through the air.
The fragment in his hand trembled, resonating with his mana, and for a moment the entire room seemed to hum in response.
Runes flared across the walls, reacting to the weapon's divine energy.
Then the system window appeared — elegant, intricate, glowing with a depth that pulsed like a living heart.
Item: Yōken no Kesshō (Crystal Blade Fragment)
Type: Katana Core – Exotic / God-tier / Evolving Weapon
State: Awakened (Recognized)
Requirements: True Demon Lord Awakening – 100% (Fulfilled)
Bound Owner: Asura Satomi
Soul Resonance: 1% (Bond Initiated)
Description:
A divine katana core born from the crystallized will of an ancient god-slayer.
Forged beyond mortal realms, its essence is not of steel but of divine soul matter, condensed into crystalline form.
The Yōken no Kesshō chooses no master by blood or title—only by resonance.
It mirrors the heart of its wielder, shifting its form, abilities, and purpose through emotion and growth.
Once fully awakened, it will forge the Yōken no Tsurugi — the Sword of the Infinite Dawn.
Hidden Potential:Unlocked
Divine Spirit Link (Passive): Weapon grows with the wielder's soul, gaining sentience and adapting in power.
Soul Compression Field (Active): Condenses divine and demonic mana into a blade strike capable of slicing through laws of reality.
Crystalline Ascension (Passive): The weapon can evolve into higher divine states, unlocking new forms and elemental alignments.
Resonant Memory (Hidden Skill): Grants the wielder access to past battle echoes of those who wielded divine arms before him.
???: [Requires further synchronization.]
Skills:
[Divine Edge – Akarion Vein] (Active): Channels divine energy through the blade, creating a cut that severs both matter and spirit.
[Soul Reverb] (Passive): Each strike amplifies resonance between wielder and weapon, increasing attack potency by 1% per chain hit.
[Echo Severance] (Active): Temporarily fractures reality within the blade's path, bypassing all physical defense and partial barriers.
[Evolving State – "Kesshō Arise"]: When synchronization surpasses 10%, the fragment reforms into its first blade state.
Asura's golden eyes widened. "This… this is insane…"
Every line pulsed with power — divine, ancient, and personal.
This wasn't just a weapon. It was alive.
It remembered.
He felt its pulse through his fingers — a quiet heartbeat echoing his own.
The crystal's glow shifted, almost brighter now, and the faint voice returned — soft and melodic, echoing in his thoughts.
"Now you see me as I am… not as what was left behind."
"Yeah," Asura whispered, smiling faintly. "You're… incredible."
The system chimed again, overlaying the luminous window with a new prompt.
[System Notice]
Recognition complete.
Soul synchronization confirmed.
Evolving Weapon detected: Yōken no Kesshō (God-tier Core).
Would you like to awaken this weapon's true form?
[YES] OR [NO]
Asura exhaled, pulse quickening.
The fragment in his palm shimmered brighter, responding to his heartbeat — as if it, too, were waiting for his answer.
He stared at it for a long moment — feeling both the gravity and thrill of the decision.
Then, slowly, a grin crept across his face.
"Guess it's about time."
He raised his hand toward the window.
"System—"
"Yes."
The moment the word left his lips, the air exploded in light.
The crystal blazed, spinning midair, shards of mana scattering like glass across the room.
Runes ignited along the walls, ceiling, and floor — the entire chamber transforming into a radiant sphere of divine energy.
Yamikami no Tsurugi hummed at the foot of the bed, reacting violently as its sibling weapon came alive.
Asura shielded his eyes against the burst, feeling the power wash over him like a storm made of light and memory.
"Then awaken me, Asura Satomi—Heir of Twilight.
Let this blade once more sing the name of its master."
✦ The Birth of the Yōken no Tsurugi
The room erupted in light.
Mana surged like a tidal wave, rippling across the obsidian floor and splitting into ribbons of gold and violet that swirled around Asura.
The Yōken no Kesshō rose from his palm, spinning faster and faster until it hung suspended in the air — a miniature star pulsing in rhythm with his heartbeat.
Asura took a step back, eyes wide.
The walls of his room groaned as magic pressure filled the air — dense, divine, and almost suffocating. The faint markings on his skin glowed to life, tracing thin lines of molten red light across his arms and collarbone.
"Our bond is forged," the voice whispered — clearer now, no longer a faint echo but a resonant presence that filled the room.
"Your soul sings with mine, Asura Satomi.
Now, behold the reflection of your own essence."
The crystal cracked.
Once.
Twice.
Then shattered outward into countless fragments of light.
Each shard hung frozen midair, spinning slowly, weaving runic circles around him. The sigils weren't demonic or divine — they were both, overlapping in impossible harmony.
Gold and black energy intertwined like threads of dawn and dusk, forming the outline of a blade.
The temperature dropped. The air tasted of ozone and burning starlight.
Asura could only stare, breath caught in his throat as the fragments converged.
The mana condensed — solidifying, reshaping — until the light faded, revealing what stood hovering before him:
A katana — slender, elegant, and utterly breathtaking.
Its blade shimmered with a mirror-like surface that reflected both light and shadow, golden veins running through the metal like living circuitry. The edge itself was faintly transparent, as though forged from condensed mana rather than steel.
The hilt was wrapped in deep violet cloth, traced with thin, glowing lines of crimson that pulsed gently in sync with Asura's aura. At the base of the guard, a circular crystal core gleamed — the same hue as the original fragment — now fused seamlessly into the weapon.
Along the blade's spine, faint inscriptions glowed with divine script, shifting constantly like living runes.
It was no longer the Yōken no Kesshō.
It was the Yōken no Tsurugi — the fully awakened Crystal God-Blade of the True Demon Lord.
The air around it hummed in reverence.

Asura exhaled slowly, eyes wide in awe.
The weapon floated closer, its tip lowering until it hovered just before his outstretched hand.
He reached forward — hesitated for half a second — then grasped the hilt.
The moment he did, a surge of energy flooded through his veins.
It wasn't pain. It was power — clean, endless, electric.
His vision flared white for an instant as his aura resonated with the blade's, filling the entire chamber with golden light.
When it finally dimmed, the blade pulsed once in his grip, settling quietly.
The voice spoke again, but now it sounded softer — closer.
Almost… proud.
"Our fates are bound, Asura Satomi.
I am your blade, and you… are my reason to exist."
Asura smiled faintly, lifting the katana so the light caught its mirrored edge.
"Then let's make this world remember our name."
The Yōken no Tsurugi thrummed in answer — a low, melodic hum that felt like a heartbeat.
At that moment, the young True Demon Lord stood bathed in the glow of his first divine weapon — heir to a throne, a curse, and now, a sword that could split the heavens themselves.
And as the last pulse of light faded from his room, the crystal fragments scattered like dust into the air, vanishing into his shadow — marking the true beginning of his legend.
✦ The Keeper's Realization
The last pulse of golden light had barely faded when the door burst open.
"Asura Satomi—what did you do this time!?"
Selene's voice hit like a shockwave before the mana in the air even settled. Her boots clicked sharply against the floor, black hair shimmering with residual magic as she stepped through the threshold—then stopped dead.
The entire room was glowing.
The walls still pulsed faintly with golden runes. The air itself hummed.
And in the center of it all stood Asura, calm as a morning breeze, holding a blade that radiated both sanctity and destruction.
Selene blinked once. Twice. Her voice dropped several octaves.
"…Tell me that's not what I think it is."
Asura smiled sheepishly, scratching the back of his neck. "Depends what you think it is."
Her eyes narrowed dangerously. "If it's the god-forged katana core your grandfather gave you as a gift for completing your first mission and told you not to awaken without supervision—"
"—Then it's definitely that."
Selene exhaled a slow, murderous sigh. "Wonderful. I was just thinking this morning lacked existential danger."
Asura raised the sword a little, its mirrored surface catching the light like a shard of the sun. "But look at it, Selene. Isn't it beautiful?"
"It's glowing, Asura. And humming. And leaking enough divine resonance to wake the entire castle!"
He tilted his head, pretending to inspect the blade. "Yeah, that's the cool part."
She threw her hands up. "Cool!? You nearly destabilized the citadel's wards!"
"Keyword: 'nearly.' No explosions this time."
The vein in her forehead pulsed. "I swear, one day—"
The rest of her scolding died in her throat as the aura around the weapon settled. The oppressive, holy-demonic pressure that had filled the room receded, leaving behind a calm hum that felt… alive.
Selene stared quietly for a long moment. The weapon wasn't just a sword—it was an extension of him. The same golden light glowed faintly behind his eyes, perfectly synchronized with the pulse of the blade.
Her irritation softened into something else—pride, awe, and a small, weary affection.
"You really did it," she said quietly. "You awakened it."
Asura smiled, genuine this time. "Guess it was waiting for me."
"Or waiting for the world to regret existing," she muttered, though her lips curved despite herself.
She walked over, examining the weapon with cautious fascination. "So this is the Yōken no Tsurugi… I can't even begin to imagine what kind of readings the Academy's instruments will register when you walk through their gates."
Asura blinked. "You think they'll notice?"
"Notice?" She gave a short laugh, half disbelief, half warning. "Asura, the moment you set foot there, every detection ward within fifty miles is going to start screaming."
He grinned, swinging the sword lightly. "Then I'll make a good first impression."
Selene pinched the bridge of her nose. "Oh, you'll make an impression all right. I just hope they have enough insurance."
He raised an eyebrow. "Insurance?"
"Never mind," she said quickly, turning toward the window. The dawn light poured through, tinting the room in rose and gold. "You leave in an hour. Try not to summon any more divine anomalies before breakfast."
As she reached the doorway, she paused, glancing back at him with a small, helpless smile. "You know… I almost feel bad for the Academy."
Asura blinked. "Why?"
Selene's grin widened just a little. "Because they have no idea what's about to walk through their gates."
She clasped her hands together in mock prayer. "May the instructors of Obsidian Fang have strong hearts… and stronger health insurance."
Asura laughed. "You make it sound like I'm dangerous."
Her tone turned mock-serious. "Oh, no, young master. You're not dangerous."
Then her expression softened, equal parts affection and dread. "You're a catastrophe with good manners."
He laughed harder, the sound bright and unrestrained.
And as Selene left the room, shaking her head but smiling, the blade in his hand pulsed once more—quietly, almost like it was laughing with him.
✦ The Demon King's Farewell
The citadel's grand hall blazed with crimson luminescence. Runes etched into its pillars throbbed faintly, like a slumbering heart remembering how to beat. Every step Asura took toward the throne echoed with quiet gravity, and two blades — one black as an eclipse, the other radiant as dawn — hung at his sides.
Yamikami no Tsurugi, the Blade of Shadows, pulsed with a soft, low hum — cold, calm, and infinitely heavy.
Yōken no Tsurugi, the newly awakened Blade of Reversal Dawn, shimmered faintly in gold and violet hues, its mirrored surface reflecting the light like liquid crystal.
Together, they gave off an aura that bent the air — divine and infernal energies coiling, merging, and canceling one another in perfect harmony.
The obsidian doors closed behind him.
Every knight and servant in the hall dropped to one knee.
The throne sat upon a dais of molten stone, and upon it — cloaked in flame and crown — sat the Demon King himself. His gaze met Asura's, and for the briefest instant, pride softened the cosmic weight in his eyes.
"So," his deep voice rumbled, shaking the marble beneath their feet, "you've chosen to carry both."
Asura rested a hand lightly on each hilt. "They chose me."
The Demon King's grin curved slow and dangerous. "Spoken like a true ruler."
He rose from the throne. The air thickened — heavy, royal, eternal. His steps boomed softly as he descended the stairs, and even the flames lining the walls bowed in his wake.
When he stood before Asura, the difference in their stature was like mountain to comet — yet the older demon saw the same fire in the boy's golden eyes that he once carried himself.
"You've grown," the Demon King said. "And yet… your recklessness grows faster."
Asura grinned. "Inherited trait, I guess."
A deep chuckle shook the hall. "Perhaps."
Then silence — a silence that carried centuries of memory.
The King reached out, resting a massive hand on his grandson's shoulder.
"Listen well, Asura," he said quietly. "The world beyond these walls doesn't see balance. It fears what it doesn't understand. And you…" — his eyes drifted to the twin blades — "you carry both judgment and salvation."
Asura's expression steadied. "Then maybe it's time the world learned both."
For a moment, pride cracked through the king's composure.
"Your arrogance would make the gods themselves nervous."
"Good," Asura said, smirking. "They should be."
The Demon King laughed — a deep, thunderous laugh that rolled like distant thunder across the chamber.
Then, with a wave of his hand, a massive crimson portal spiraled open behind the throne, its surface glimmering with layered divine-demonic runes. Energy poured from it in waves — hot, radiant, alive.
"Obsidian Fang Academy," the Demon King said, his tone turning solemn. "The cradle of our future generals. Your enrollment has been arranged. Learn what you can… and try not to burn it down."
Selene stepped forward from the side, arms crossed, expression torn between amusement and dread.
"Try not to burn it down," she repeated. "Not destroy, not reshape, not accidentally level a mountain — burn it down. That's the goal, apparently."
Asura chuckled. "No promises."
The Demon King smirked faintly, gaze softening one last time.
"You are my blood, Asura Satomi — the bridge between the abyss and the heavens. Do not forget that."
He lifted his hand; the twin blades at Asura's hips thrummed in unison, their resonances intertwining like two heartbeats sharing one rhythm.
"Go, Heir of the Infernal Veil," the King declared, voice echoing through the pillars.
"Let the realm witness the harmony of shadow and light."
Asura bowed his head respectfully. "I'll make you proud, Grandfather."
"I am already proud," the King said softly. Then his eyes gleamed. "Now make me entertained."
Selene sighed. "That's not what a responsible monarch says."
The Demon King grinned. "I've never been responsible."
He raised his hand — and the portal flared open like a scarlet sun.
Wind and mana howled through the hall as Asura stepped forward, both swords glowing faintly in response.
Selene called out, voice cutting through the storm.
"Asura—! Try to act normal!"
He looked back, flashing a mischievous grin. "I'll try… but no promises!"
And with that, he stepped into the light.
The portal sealed behind him in a flash of crimson, leaving only the lingering hum of twin sword auras.
For a long while, the hall stood in silence.
Then Selene exhaled, pressing her palms together.
"May the Academy's instructors survive the week," she muttered. "They have no idea what's coming."
The Demon King chuckled deeply, sitting back upon his throne.
"They'll learn soon enough… that my grandson doesn't attend classes."
