The hallway still smelled like antiseptic and fear.
It clung to the walls, the floor, the people who walked through it like ghosts pretending to be alive.
Kenji stood at the end of it.
Still.
Watching.
The nurses hadn't returned.
Not after what happened in the room.
Not after the monitors screamed—
and then stopped.
He looked down at his hands.
Steady.
Too steady.
That feeling returned.
The ripple.
The echo.
But now it was clearer.
Not just inside him.
Around him.
The lights above flickered.
Once.
Twice.
Then—
they went out.
Darkness swallowed the hallway.
Silence.
Then—
a sound.
Not footsteps.
Not movement.
Breathing.
Behind him.
Kenji didn't turn.
"…you're not supposed to be awake."
The voice was low. Calm. Controlled.
Too controlled.
Kenji tilted his head slightly.
Not fully looking.
Just enough.
A man stood at the far end of the corridor.
Black coat.
No badge.
No reflection in the glass beside him.
That was wrong.
"You died," the man said.
A pause.
"So why are you still here?"
Kenji turned fully this time.
Eyes locking.
"I was going to ask the same thing."
The man smiled.
Not friendly.
Not hostile.
Interested.
"…good," he said.
"Then you're already thinking."
The air shifted.
Subtle.
But real.
That ripple again.
Stronger.
The man stepped forward.
Slow.
Measured.
Each step felt heavy—
like the world was aware of him.
"You felt it, didn't you?" the man said.
"That moment."
Kenji didn't answer.
The man continued.
"When everything stopped."
"Not your heart."
"Not your body."
His gaze sharpened.
"Something else."
Silence.
Then—
Kenji spoke.
"…the echo."
The word slipped out.
The man's smile widened.
"There it is."
Another step closer.
"You shouldn't know that word."
The lights flickered again—
but this time, they didn't come back.
Darkness pressed in.
The man stopped just a few feet away.
Close.
Too close.
"You came back wrong."
A beat.
"Do you know what that makes you?"
Kenji didn't move.
Didn't blink.
"…alive."
The man chuckled softly.
"No."
A pause.
"Alive is what you were."
The air tightened.
"Now?"
He leaned in slightly.
"You're something that shouldn't exist."
The echo surged.
Violent.
Kenji staggered—
just a fraction—
but enough.
The man noticed.
"Ah," he whispered.
"Still unstable."
His hand lifted.
Slow.
Not threatening.
Not yet.
"But that's fine."
Another step.
Now face to face.
"We have time."
Silence stretched between them.
Then—
"…do you want to know why you came back?"
No hesitation.
"Yes."
The answer came instantly.
The man studied him.
Then smiled.
"Good."
He straightened.
Turned slightly.
"Then don't die again."
And just like that—
he was gone.
No footsteps.
No sound.
No trace.
The lights came back.
The hallway returned.
Empty.
Like nothing had happened.
But the echo remained.
Louder now.
Kenji stood there.
Breathing.
Thinking.
One question looped in his mind.
Not fear.
Not confusion.
Something else.
If I wasn't supposed to come back…
His fingers curled slightly.
…then what brought me back?
The echo answered.
Not in words.
But in presence.
Watching.
Waiting.
Awake.
