Chapter Text
“You can’t be suggesting that—”
“It’s your decision. Always.”
“Go to hell, damn it,” Chuuya spat, furious. He was shaking as he stripped off his gloves, something eerily close to fear tightening around his chest. He opened and closed his hands, feeling naked, exposed. Dazai caught the gloves midair and pressed them to his chest. “You’d better stop me in time.”
The corner of his mouth curved ever so slightly.
“Of course, partner.”
The bodies of their subordinates painted a macabre picture as far as the eye could see, and death loomed over them like a starving beast. They were at the end of their strength; they were out of ammunition, and communications were down.
He dug his nails into his palms, and a traitorous tear slid down his cheek. Losing control, surrendering it like this… it was horrifying. He took a tentative step forward. Everything reeked of desperation. And yet, later, he wouldn’t remember what had ever made this enemy worth Corruption.
Wasn’t that pathetic?
And still, it was his duty—to unleash the god from its chains and turn its fury loose upon his enemies. To prove to himself, and to those who had done this to him—who had split him open and sealed something ancient inside—that he was far more than a failed experiment, far more than a weapon programmed for destruction.
He swallowed. Fear crawled up his spine, stretching its long fingers toward his throat. There was a bitter taste on his mouth, earthy and metallic. Slowly, he drew in a trembling breath and prepared to shape the words that haunted him—words that would damn him, heavy against his tongue.
His shoulders shook, and it had nothing to do with the cold clinging to the old warehouse.
Every time he loosened the leash, he was one step closer to not coming back. But Dazai would reach him, that bastard always did. No matter how hard it was, no matter the insurmountable distance between them—miles, at times. The damn sky. He always made it to him. As Chuuya shrugged off his leather jacket and crossed the battlefield, an infuriating little grin danced across his lips. “I’m here,” it seemed to say. “I’m gonna kick your asses, assholes.” No more than a flimsy shield—one he used against himself and against the world that had pushed him to the brink—but a shield he had no intention of discarding.
Ten minutes.
“Oh grantors of dark disgrace—”
He started counting as soon as the first words slipped from his lips, ancient and powerful, burned into his code. For a single second, silence swallowed the world whole, and it bowed toward him, begging for mercy.
“—do not wake me again!”
And then, a shrill sound cut through the air.
Or maybe it was a laugh—the madness of something ancient gnawing at his insides. A god. A singularity. Did it even matter? A monster without a leash.
Ten fucking minutes.
His bones shattered to make room for gravity. His muscles tore apart, unable to contain the fury ripping through him, and his skin seared from within, tongues of fire and black blood carving grooves, spirals, runes—perhaps a language older than humanity, or perhaps just another flaw in his programming.
The cry of exultation that tore from his throat echoed against the warehouse’s fragile walls. They wouldn’t be enough to hold him, but he hoped, his mind’s fraying threads on the verge of snapping, that they would last long enough to end this.
His lips stretched into an impossible smile, and he curled his fingers—broken, claws eager to rend skin, muscle, bone—to bend gravity to his will. Soon, control would slip through his grasp. He had never told anyone, but he could feel it—the God, or whatever it was, coiled within his skin, whispering poisoned promises into his ears, and this, these first few seconds.
Ten seconds.
Two craters formed at his feet as he leapt, the ground buckled, and gravity answered his call. Bodies vanished beneath the weight, pressed into the earth, erased.
Eight seconds.
This was the point of no return—the moment where names stopped meaning anything.
A black hole bloomed between his fractured fingers, hungry and alive, and the screams that erupted made his skin prickle. Men were dragged across the ground, their boots scraping, hands clawing at air, until gravity claimed them entirely.
Five seconds.
It flared—the desperation lodged in his chest, the unbearable certainty of lives ending under his will, and the last remnants of a humanity that had never belonged to him. His consciousness began to slip, surrendering to the vast, impersonal force pouring through him, and gravity yielded to him, absolute and unforgiving.
No, he had never told anyone.
Not even—
Dazai, he thought—or maybe screamed in silence. Dazai. Dazai. Dazai.
His anchor.
His executioner.
His ruin.
His—
And he never would.
Don’t be late, bastard. Don’t you dare.
Black spots flooded his vision, clawing at his mind and twisting his senses—perhaps the god tearing control from him, or perhaps the abyss that heralds the awakening. The storm.
Just nine more minutes.
…until the show ended.
A smile touched Dazai’s mouth—small, reflexive, wildly inappropriate.
Corruption was efficient. Unquestionably so. It was also—though he would never say this aloud—beautiful.
Whether it was the terrifying elegance of Chuuya dismantling a battlefield, or the absolute trust implicit in allowing himself to come apart like this, Dazai didn’t bother sorting out. But watching his partner suspended between gravity and annihilation, body operating on instinct alone, was always astonishing.
He kept his distance, though. That lesson had been learned early. This power did not discriminate. Neither did debris, once gravity stopped pretending it mattered.
Chuuya hovered at the centre of the devastation.
The warehouse was gone now—structures disintegrating like wet paper, concrete screaming as it tore free beneath the red hue pouring off him in violent, rhythmic surges.
Then—behind him—that familiar silhouette unfurled.
Not wings. Never wings.
There was no lift to them. No elegance. Only mass. Pressure. Power forced into a shape because it had nowhere else to go. Darkness folded outward, vast enough to make the sky look fragile, pulsing as Chuuya rose higher—out over the open water of Yokohama Bay.
There was nothing left to contain him.
Control him.
Nothing that could—but Dazai.
And for a brief, obscene moment, everything reorganised itself around Chuuya Nakahara and the thing wearing his outline.
A beast.
A God.
And unmistakably—
Human.
Eight minutes.
Chuuya’s humanity had never been guaranteed.
That was the part everyone preferred to fixate on—how quickly Corruption hollowed him out, stripped him down to instinct and violence and momentum. How willingly Chuuya handed himself over to it, fully aware of the cost.
Corruption didn’t preserve him.
It erased him.
And still—
Dazai watched, expression neutral, and let certainty settle where doubt failed to take root.
Corruption might take Chuuya’s voice. His restraint. His hesitation. It might burn through his identity like fuel.
But no matter how vast the power became, or how inhuman the silhouette grew—the core remained unchanged.
There was no one more stubbornly, aggressively human than Chuuya.
And that was what mattered.
Seven minutes.
Dazai exhaled slowly, each breath a beat, a count.
He never used a timer. Corruption had a rhythm—predictable, almost polite, if you respected it.
Like holding your breath underwater.
There was a limit.
You didn't cross it.
Too early and the work got sloppy.
Too late and—
That wasn’t happening.
Everything was proceeding exactly as designed.
Gravity obeyed. Matter complied. Structures collapsed. Shockwaves rippled outward, pulverizing what little resistance remained. All that was left was to let Chuuya burn hot enough to break the enemy’s spine. Let him exhaust the excess.
Then step in. Touch. Nullify.
Oh—and catch him when he falls.
Six minutes.
Dazai tilted his head. The frown came a second later, faint and unwelcome.
Something felt… off.
Not the power. That was familiar. He knew its violence, its weight, the way it bent reality under its grip. He’d learned to read it like weather. Chuuya had always been predictable in his destruction.
This felt like momentum.
Like the instant before freefall.
He catalogued it automatically.
Angle.
Spread.
Density.
Still within tolerance. Still acceptable.
Five minutes.
Pressure spiked hard enough that Dazai felt it in his bones now.
Sudden.
Nauseating
He kept his hands loose at his sides. Shoulders easy.
Watching—
—Chuuya twisted midair.
Cut through space with sharp precision.
Too sharp.
Each impact landed a fraction too soon. Not wrong—just early.
But the red glow didn’t stutter.
If anything, it compressed. Burned denser.
And the darkness—
that flared wider—
not outward, but inward, collapsing toward the core in a way that—
Four minutes.
—wasn’t burn-off.
Or how this was supposed to feel.
His stance adjusted—habitual, unconscious.
Not forward. Just—closer.
Just incase—
No.
The timing—his timing—was right.
He knew it.
Corruption still held. The rhythm hadn’t broken. Chuuya was still moving with intent. With control.
He was—
Three.
—fine.
Chuuya was—
The scream tore through the air.
The red waves ruptured.
The dark wings imploded.
And a body fell.
Small.
Limp.
Horrifyingly human.
Dazai saw it immediately—
the distance.
the open water.
the empty span of air
where he should have been standing.
For half a second, he did nothing.
Calculation stalled. Timing shattered.
There was no clean solution left.
Because he was—
two—
—far.
“Shit—”
He knew it the instant his feet left the ground.
ran.
Knew he wouldn’t make it.
Knew the spacing was wrong,
the angle worse.
Hands reached anyway.
Fingers stretching, burning, desperate—
because he had to reach him.
Because he’d promised—
O n e.
Chuuya hit the waterfront with a sickening sound.
A brutal, final impact—flesh and force meeting water at terminal velocity—as the harbour surged up and closed over him, swallowing red light, swallowing movement—
—swallowing him.
Dazai jumped—
The angle was wrong.
The distance unforgiving.
There was nothing left to solve—no timing to salvage, no correction to make.
—and dove.
Hit the water hard enough to rattle his teeth, cold punching the air from his lungs as the harbour closed over him too, dark and choking and absolute.
No calculation.
No plan.
Only the terrible, undeniable truth settling in as he sank after the empty space where Chuuya had disappeared—
that for the first time since Corruption had scared his skin…
Dazai Osamu had not been there to catch him.
