Pain did not wake Kaito.
Silence did.
Not the absence of sound, but a silence so complete it erased the idea of noise altogether. Even his breathing felt distant, as if it belonged to someone else.
He opened his eyes.
Or thought he did.
The world around him was pale—washed of color, washed of texture. He stood barefoot on a smooth surface that reflected nothing, a horizon that refused to curve or end. Above him, the sky was a blank sheet of white, unmarked by clouds or light.
— This again…, he murmured.
The training space had swallowed him.
Or perhaps—
he had fallen inward.
His left eye burned softly, not in warning, but in recognition.
— You always come here when you're about to break.
The voice came from behind him.
Kaito turned.
His mother stood a few steps away.
Not as he remembered her in photographs.
Alive.
Breathing.
Her hair tied back loosely, sleeves rolled up, a faint smear of grease on her cheek like she had been working on something mechanical. Her eyes were tired—but warm.
Kaito's chest tightened violently.
— …You're not real.
She smiled gently.
— Neither is this place.— But you still listen when you're here.
His legs gave out.
He fell to his knees, hands shaking, fingers digging into the white surface that felt cool and solid beneath his skin.
— I tried to stop it, he said, voice cracking.— I tried to keep it from ending.
She knelt in front of him, close enough that he could smell oil and metal—familiar scents from his childhood.
— We know.
His father appeared beside her.
Taller. Quieter. His eyes sharp, calculating, always watching the space between things. He placed a hand on Kaito's shoulder, firm and grounding.
— That's why this hurts, his father said.— You're doing it right.
Kaito shook his head violently.
— I'm not strong enough.— A Warden almost killed Ryuji.— The Association—
— —is not one enemy, his mother interrupted.
The white space shifted.
Lines appeared beneath their feet, forming a massive diagram that stretched outward in all directions. Circles. Arrows. Layers stacked atop one another.
— It's a structure, his father said.— Not an army.
The diagram lit up.
At the bottom: Observers.Above them: Collectors.Above that: Regulators.Then: Wardens.
And above even that—
A space deliberately left blank.
— The Ten don't rule the Association, his mother said quietly.— They enforce its limits.
Kaito's left eye throbbed.
— Then who decides?
His father's expression darkened.
— Those who never fight directly.
The diagram shifted again.
One symbol appeared near the top.
Not a circle.
Not a triangle.
A vertical line, intersected by a faint zero.
Kaito's breath caught.
— That mark…
— That is a designation, his father said.— Not a name.
His mother reached out, touching the symbol.
— A role given to someone who should not exist.
The white space trembled.
A second figure appeared at the far edge of the diagram.
A boy.
Older than Kaito by a few years.
His face was turned away, features obscured, but Kaito felt it instantly—like a missing limb suddenly aching.
— No…, he whispered.
The boy didn't look back.
A black band wrapped around his arm, etched with a codename that burned itself into Kaito's vision.
SUBJECT: AXIS-13
— He was never meant to be a weapon, his mother said softly.— He was meant to be a solution.
Kaito surged forward—
—and the world shattered.
He woke up screaming.
The sound tore from his throat, raw and uncontrolled, echoing through the layered training space. His body convulsed as if dragged back into itself too fast. Every nerve screamed in protest.
He collapsed forward, hands digging into rough stone this time—not white nothingness, but the scorched ground of the training construct.
His vision blurred.
Sweat soaked his back.
His left eye burned like it had been peeled open.
— Breathe.
Iori's voice.
Calm. Present.
Kaito sucked in air, chest heaving, lungs burning as if he had been underwater too long.
— You saw them, Iori said.— Not memories.— Constructs.
Kaito forced himself upright, shaking.
— My parents.
Iori didn't correct him.
— And something else, Iori continued.
Kaito looked up slowly.
— You know.
Iori crouched a short distance away, coat brushing the ground, eyes sharp but not unkind.
— I know of him, he said.— Not who he is.
He tapped the incomplete Key hanging at his side.
— The Association assigns roles long before it assigns names.
Kaito clenched his fists.
— Axis-13.
The name tasted like iron.
Iori nodded once.
— A codename used for individuals placed at structural crossroads.— Not Ten.— Not Wardens.
— Then what?
Iori's gaze hardened.
— Anchors of inevitability.
The words hit harder than any blow.
— He ensures outcomes converge, Iori continued.— When even the Ten fail.
Kaito's left eye pulsed violently.
— You're telling me he's my enemy.
Iori tilted his head.
— I'm telling you he exists.— And that the Association does not deploy him lightly.
Kaito's jaw trembled.
— Why tell me this now?
Iori stood.
— Because training without context is cruelty.— And because if you meet Axis-13 unprepared…
He didn't finish the sentence.
He didn't need to.
The training space shifted violently around them. In the distance, Kaito felt the pressure of Ryuji's trial spike—raw, furious resistance pushing against something overwhelming.
— Your friend is breaking his limits, Iori said.— Not winning.— But refusing to collapse.
Kaito wiped blood from beneath his eye.
— That's what we do.
Iori studied him.
— That's why you scare them.
The symbols in the air around Kaito reorganized subtly—less chaotic than before. More deliberate.
— This dream wasn't an accident, Iori said quietly.— The Keys didn't just open this place.
— They opened you.
Kaito closed his eyes, steadying his breathing.
— Then next time…
He looked up.
— I won't just delay the ending.
Iori's lips twitched.
— Careful, Zero.— That's how stories stop being survivable.
The training space surged again.
Somewhere deeper within it, something ancient listened.
And far away, within the Association's highest layer, a single record updated.
AXIS-13 – STATUS UNCHANGEDZERO – DEVELOPMENT DEVIATING
For the first time in a long while—
The system hesitated.
