Chapter Text
The first thing Isagi notices is the hum.
Not loud. Not mechanical in an obvious way. Just a low, persistent vibration in the walls — the kind that settles into bone before you recognize it as sound.
He opens his eyes slowly.
The ceiling above him is white — but not painted white. It’s seamless. Glossy. Like a single poured surface of enamel. No seams. No cracks. No light fixture. Yet the room is illuminated evenly, shadowless.
The bed beneath him creaks in a way he recognizes—Blue Lock’s standard dorm frame. Industrial, minimal. Identical to the one he slept in during the project.
But the project ended.
Didn't it?
His pulse spikes and sits up too fast. The dorm looks the same...also not.
The sheets smell like antiseptic and something faintly metallic, like cold air in a hospital hallway. The desk is in the same place. The locker sits against the opposite wall.
But there’s no window.
There should be a narrow reinforced window near the ceiling, instead, there is only wall.
Flat. Endless. White.
Isagi swings his legs over the side of the bed. The floor is cold against his bare feet — colder than it should be. Polished concrete, but almost damp with chill.
The door is still there. Heavy steel, matte black. A small digital panel beside it.
“Hello?” His voice sounds smaller than he expects.
No answer.
He stands slowly and moves toward the door. The digital panel is dark. No green light. No red.
Just black.
He enters the numbers anyway—
299
Red light flashes. Incorrect.
A thin line of unease slides down his spine. “Okay,” he mutters to himself. “Okay. Think.”
This has to be some kind of extension program. A test. A simulation. Blue Lock always thrived on psychological strain.
But—
He doesn’t remember coming back.
He remembers the last match. The cheers, the stadium lights, remembers going home.
Then—
His thoughts snag like fabric on wire.
There’s a gap. A soft blank space where memory should be.
The fluorescent light above flickers just once, then steadies.
Isagi turns, and that’s when he notices the clock above the desk.
06:00.
He stares at it for a moment. The seconds aren't ticking. No digital glow.
Just a printed “06:00” behind the glass, as if someone placed a photograph there.
A screen flickers to life on the wall opposite his bed. He swears it wasn’t there a moment ago.
Isagi jerks back, startled.
The wall pixels ripple like liquid, forming a rectangular monitor embedded seamlessly into the surface.
Static crackles, then a face appears. Sharp glasses. Crooked grin.
“Good morning, Blue Lock.”
Isagi exhales a breath he didn’t realize he was holding.
Ego Jinpachi.
The relief is immediate. Irrational. Automatic.
Ego tilts his head. “You look confused.”
The audio glitches slightly — a fraction of a second delay between lip movement and sound.
Isagi frowns. “Where are we?” he mutters, though he knows Ego can’t hear him.
“Welcome," Ego continues, "to Stage One.”
The words hang strangely. Stage One?
“Blue Lock will now enter its final evolution.”
The screen flickers. For a split second, the image distorts — Ego’s eyes stretching vertically before snapping back.
Isagi’s stomach tightens.
“From this point forward, advancement will be earned through survival.”
A pause.
“Survive to evolve.”
The screen glitches again. Static bleeds across Ego’s face. “Pairings have been assigned. Those who cannot evolve,” Ego says, “will be recycled.”
Assigned? Recycled?
“Doors will unlock in five… four…”
The countdown distorts at “three.” The number flickers between 3 and 8 and 0 before stabilizing.
“…two. One.”
A heavy metallic thunk echoes through the room. The door panel flashes green. The hum in the walls lowers slightly, like a breath released.
Silence follows.
Isagi stands frozen for five seconds. Then he reaches for the handle and pulls. The door opens outward with a hydraulic hiss.
The corridor beyond is—
White. Brighter than the dorm. Longer than it should be.
Blue Lock’s hallways are concrete gray, industrial, sharp-edged. This one curves gently, vanishing around a bend he’s never seen before.
Footsteps echo from the left.
He turns to the sound.
Bachira steps out of his own dorm room across the hall, blinking like someone waking from anesthesia.
“Yo, Isagi.”
His smile is present, but doesn't quite reach his eyes.
“Is it just me,” Bachira says softly, “or does it feel… off?”
Isagi doesn’t answer. More doors open.
Chigiri emerges, hair disheveled, eyes scanning sharply. Kunigami steps out behind him.
Karasu leans in his doorway, already frowning.
Barou exits with visible irritation, glancing around like he expects someone to challenge him.
Reo appears down the hall. Nagi follows behind, yawning.
More familiar faces. Hiori. Yukimiya. Shidou. Kaiser. Ness.
And then—
Rin.
He stands several doors down, expression already sharpened into suspicion.
Their eyes meet for half a second. Rin looks away first.
“What the hell is this?” Barou growls, scanning the corridor.
“Did you hear that announcement?” Chigiri asks.
Isagi nods slowly.
“Stage One,” Hiori murmurs. “That’s not terminology Blue Lock used before.”
“Yeah,” Karasu mutters. “And what the hell does ‘recycled’ mean?”
A metallic click reverberates above them. All heads tilt upward.
Cameras. Small, black-domed surveillance cameras slide out from the ceiling panels.
They rotate simultaneously. Each one locks onto a player. Isagi feels the lens settle on him. He suppresses the urge to step backward.
“Ah,” Ness says quietly. “We’re being watched.”
“Obviously,” Kaiser replies lazily, though his eyes flick briefly toward the nearest camera. “It’s Blue Lock.”
“But the project ended,” Kunigami says.
Silence. They all remember. They all know it ended.
“Maybe it didn’t,” Shidou grins. “Maybe this is the fun part.”
“Shut up,” Yukimiya snaps.
The corridor lights flicker once. Then an alarm chimes overhead. A mechanical female voice fills the hall.
“Pair assignments have been determined. Please proceed to central atrium.”
Arrows light up along the floor, glowing faint blue. They lead down the strike white corridor.
No one moves at first.
Then Barou clicks his tongue and starts walking. The others follow.
Isagi falls into step automatically. Rin walks two paces behind him.
He notices, but doesn’t comment.
The central atrium is larger than it used to be. Or maybe the walls are farther away.
Or maybe—
No. Something is definitely wrong.
The ceiling arches higher than he remembers. Too high. The glass roof above them doesn’t show sky. Just a plain white ceiling.
The doors seal shut behind them. Then a giant monitor descends from the ceiling. Ego’s face appears again.
“Stage One: Trust Calibration.”
Names flash across the screen. Pairs align one by one.
Bachira / Barou
Chigiri / Kunigami
Nagi / Reo
Kaiser / Ness
Karasu / Shidou
Hiori / Yukimiya
The final names apappear.
Isagi / Rin
A strange silence falls.
Rin exhales slowly through his nose. “Of course,” he mutters.
Isagi’s stomach tightens. He doesn’t know whether to feel relieved or terrified.
Rin meets his gaze. There’s something unreadable in his eyes. Not anger, not rivalry either.
“If you slow me down,” Rin says quietly, “I won’t carry you.”
Isagi forces himself to hold eye contact. “Same goes for you.”
For a moment, something almost like a smile threatens Rin’s mouth. Then it disappears just as quickly.
Ego speaks again. "You will be escorted to your designated rooms.”
Doors slide open around the perimeter of the atrium, dark corridors beyond them.
“Failure,” Ego says softly, “will be educational.”
The monitor glitches. For a split second the image fractures into jagged blocks of static. Ego’s face stretches unnaturally wide, his smile dragging across the screen like a wound being pulled open. Then it snaps back.
No one laughs.
No one speaks.
The silence in the atrium grows heavy enough to feel physical.
“Please proceed,” the mechanical voice repeats.
A dull chime echoes from the open corridors. Isagi notices something then. The doors are not identical. Each corridor is marked with a number burned directly into the metal floor.
A pair of numbers appears beside each player name on the monitor.
The numbers beside Isagi / Rin read:
03
A low buzz vibrates through the ground.
“Guess that’s ours,” Bachira says quietly, pointing toward Corridor 01 where the floor number pulses faintly. Barou cracks his neck and walks off without another word.
Chigiri and Kunigami exchange a brief look before heading toward Corridor 02.
Nagi yawns loudly. “Reo, if this turns out to be annoying, I’m blaming you.”
Reo sighs. “You blame me for everything.”
Their footsteps fade.
Soon only a few players remain in the atrium.
Kaiser stretches lazily. "Later, Yoichi," he says before drifting toward Corridor 04, Ness already trailing him like a shadow.
Karasu whistles softly. “Well, partner,” he says to Shidou, “this should be entertaining.”
Shidou grins. “Hope there’s blood.” They disappear into Corridor 05.
The room grows quiet.
Only two players remain.
Isagi.
Rin.
And the faint hum of machinery somewhere deep inside the building.
Isagi looks toward Corridor 03. The lights inside it flicker faintly, illuminating a long hallway that curves slightly to the right.
He swallows.
“Well,” he says. Rin doesn’t answer. He’s staring at the ceiling.
Isagi follows his gaze.
The cameras. They’re moving again. Not scanning, but watching. Each lens adjusts slowly until they point directly at the two of them.
Rin’s expression tightens. “Let’s go,” he says. His voice is flat.
They walk. The moment they step into Corridor 03, the atrium doors slam shut behind them. The sound reverberates through the hallway like a gunshot.
