The sky over Shirogane District had been blue for exactly one hundred and forty-seven days.
Not the pale, washed-out blue of winter mornings, but a deep, almost defiant blue—the kind that felt like the universe was trying too hard to prove it still remembered how to be normal.
Kai Ren stood on the rooftop of the rebuilt Ryujin High, uniform jacket flapping in the late-spring breeze, and stared at that sky like it might change its mind any second.
It didn't.
Below him, the courtyard bustled with students. Laughter echoed off new concrete. Banners for the upcoming inter-district aura tournament snapped in the wind. Someone was practicing a low-level flame burst near the training field—bright orange sparks that died harmlessly against the reinforced barriers.
Everything looked… fine.
Everything felt wrong.
Kai's right hand twitched. Under the sleeve, the faint scars where the Nine Seals had once burned were barely visible now—just pale lines, like old burns from a childhood accident no one remembered. He flexed his fingers. No heat. No pulse of ancient fury. No wings threatening to rip out of his shoulder blades.
He was fifteen. Human. Ordinary again.
And he hated it.
"Still waiting for the sky to bleed?" a voice asked behind him.
Kai didn't turn. He didn't need to. The footsteps were light, precise, carrying the faint chill of winter even in May.
Aria Mitsuki stepped up beside him, silver hair catching the sunlight like frost on steel. She wore the school uniform with the dark armband of the discipline corps, short-blade concealed beneath her blazer as always. Her ice-blue eyes scanned the horizon, then flicked to him.
"You're late for class," she said.
"I know."
"You've been late every day this week."
"I know."
She was quiet for a moment. Then: "It's not coming back, Kai."
He finally looked at her. "You don't know that."
"I know you haven't slept in three days. I know you flinch every time the sky clouds over. I know you check the news feeds for 'color drainage incidents' before you even brush your teeth."
Kai's jaw tightened. He turned back to the sky.
Aria sighed. "The world didn't end. You stopped it. Let yourself breathe."
He wanted to. God, he wanted to.
But every night he dreamed of red threads pulling galaxies apart. Every night he heard that patient, endless voice counting down three heartbeats that had somehow stretched into months.
And every morning he woke up reaching for power that wasn't there anymore.
The bell rang. Students below began filing into buildings.
Aria nudged his shoulder. "Come on. Hayato-sensei's subbing for combat theory today. He'll notice if we're both missing."
Kai followed her down the stairs in silence.
The hallway smelled like new paint and floor wax. Lockers slammed. Someone laughed too loud. A girl with minor wind aura levitated her books to her friend. Everything normal.
Kai's locker opened with a soft click. Inside: textbooks, a half-eaten rice ball from yesterday, a photo taped to the door—Aria, Caelum, Reina, and Hayato standing around him in the grass the day he woke up after crushing the Eye. All of them smiling like they'd won something permanent.
He stared at it too long.
A shadow fell over him.
"Hey, Ren."
The voice was casual. Friendly, even.
Kai turned.
A boy he vaguely recognized—third-year, tall, used to run with Daiki's old crew—stood there with a easy grin. His aura flickered faint gold, mid-tier Earth-rank. He'd filled out since last year. Looked stronger.
"Been meaning to say," the boy continued, "what you did last year… taking down that thing in the sky? Insane. Respect, man."
He held out a fist.
Kai stared at it like it might explode.
The boy's grin faltered. "Uh. No pressure. Just… yeah. Respect."
He lowered his hand awkwardly and walked away.
Kai closed his locker.
Aria watched from a few steps down the hall, expression unreadable.
"See?" she said quietly. "People aren't afraid of you anymore. Some of them even—"
"Don't," Kai cut in. His voice was rough. "Just… don't."
He walked past her toward class.
She followed without another word.
Combat theory was held in the new auditorium—the old one had been vaporized during the final battle. Sunlight streamed through reinforced glass windows. Students filled the tiered seats.
Instructor Hayato Kurogane stood at the podium, charcoal suit immaculate, ponytail tied low. The dragon-sword emblem glinted at his collar. He didn't look like a man who had once stood between a war demon and a crown prince of ruin.
He looked like a teacher.
On the screen behind him: a frozen frame of the Day the Sky Bled. The massive crimson eye hanging over the city. A tiny figure in the center—wings of ash and iron, fist raised.
The class fell silent as Kai and Aria slipped in late.
Hayato's eyes flicked to them. He nodded once. No reprimand.
"Today," he said, voice calm, "we discuss aftermath."
He clicked the remote. The image zoomed in on the tiny figure.
"Most of you lived through this. Some of you fought in it. All of you carry the scars—visible or not."
A few students shifted uncomfortably.
Hayato continued. "The entity known as the Crimson Eye was classified as an Omega-level existential threat. It was defeated by a single student. Kai Ren."
Every head turned.
Kai felt the weight of fifty stares. He kept his eyes on the floor.
Hayato let the silence stretch. Then: "But defeat is not the same as destruction. Questions remain. What happens when something that old… adapts?"
The screen changed. News clips: a child in Europe healed of terminal illness by a "red-haired angel." A village in Africa saved from drought by sudden crimson rain that revived crops overnight. A warlord in the Middle East executed publicly by his own soldiers after a teenage figure whispered in their ears.
All incidents linked to the same description: androgynous teen, shifting crimson hair, eyes like dying stars.
The class murmured.
Hayato clicked again. A grainy photo: the figure standing in a hospital ward, hand on a dying patient's forehead. The patient's wounds closing. The figure smiling gently.
"This individual has been sighted on every continent in the last four months," Hayato said. "No name. No demands. Only… miracles."
A girl in the front row raised her hand. "Is it… him? Ren?"
Kai's stomach twisted.
Hayato's gaze flicked to him, then back. "No. Kai Ren is here. In this room. Attending class."
Laughter rippled—nervous, relieved.
Hayato didn't smile. "But the energy signature in these incidents matches residual fragments of the Crimson Eye. Conclusion: it did not die. It scattered. And something is collecting the pieces."
The auditorium went still.
Hayato turned off the screen. "Your assignment: research historical precedents of defeated entities returning in new forms. Due next week."
The bell rang.
Students filed out, whispering.
Kai stayed seated.
Aria lingered by the door.
Hayato approached slowly.
"You felt it," he said quietly. Not a question.
Kai nodded.
"Last night," he whispered. "In my dream. The threads… they were moving again. Like they were looking for something."
Hayato's expression darkened. "The Wardens have been tracking the miracles. They believe the fragments are seeking a compatible vessel. A human one."
Aria stepped closer. "Why human?"
"Because we beat it with humanity," Hayato said. "Stubborn, messy, refusing-to-die humanity. If it wants to understand why it lost… it needs to wear that."
Kai's hands shook.
Hayato placed a hand on his shoulder. "You burned out your channels to destroy it. You're safe. It can't use you again."
But Kai heard the unspoken: Someone else.
The rest of the day passed in a blur.
Lunch on the roof alone.
Training field after classes—punching bags until his knuckles bled, trying to summon even a spark of the old power. Nothing.
Walking home through streets that looked too bright, too colorful, like the world was overcompensating.
His apartment was empty. Mom working double shifts at the rebuilt hospital.
He cooked instant ramen. Ate half. Stared at the TV.
News anchor: "—another miracle in Seoul today. A teenage figure reportedly revived a coma patient—"
Kai turned it off.
He went to bed early.
And dreamed.
He stood in a vast red plain under a starless sky.
Threads floated everywhere—thin, crimson, pulsing.
They wove together slowly, forming a shape.
Human.
Teenage.
Beautiful.
The figure opened its eyes—galaxies dying inside them.
It smiled at Kai.
"Thank you," it said, voice soft, layered, ancient. "You showed me how to dream better."
Kai tried to scream.
Couldn't.
The figure reached out.
Its hand passed through his chest.
When it pulled back, it held a single red thread.
Kai's heart stuttered.
The figure tilted its head.
"Almost ready."
Then the dream shattered.
Kai jolted awake, gasping, covered in sweat.
The clock read 3:17 AM.
His phone buzzed on the nightstand.
Unknown number.
A video message.
He opened it with trembling fingers.
Grainy footage—security camera in a hospital ward.
A child on life support. Family weeping.
A teenage figure in a hooded jacket enters. Hood down: shifting crimson hair, face androgynous and perfect.
The figure places a hand on the child's chest.
Monitors flatline.
Then beep steadily.
The child opens their eyes.
The family sobs in joy.
The figure turns to the camera—as if knowing it's there.
Smiles gently.
And speaks directly to the lens.
"Hello, Kai Ren."
The voice was everywhere. In the room. In his skull.
"I've been waiting to meet you properly."
The figure's eyes flare crimson.
Behind them, for a split second—an enormous eye opens in the darkness.
Then the video ends.
Kai dropped the phone.
His heart hammered.
And for the first time in one hundred and forty-seven days…
…the voice returned.
Not as a roar.
Not as thunder.
Just a low, familiar growl—tired, proud, and very much awake.
**Well, boy. Looks like the bastard learned to knock.**
Ravnos.
Kai's breath hitched.
**You burned us both out crushing it. But blood remembers. And so do I.**
A pause.
**Get up. Training starts tomorrow.**
**Because it's back.**
**And this time… it's wearing a face.**
