They thought he was dead.
No Gate had opened. No dungeon had been reported. Kazuki Ryou simply vanished—no blood, no sign, not even a ripple in the system. Three years passed, and the world moved on.
Until today.
He stepped out from an alley behind his old school, barefoot, bloodstained, eyes hollow from a thousand lifetimes lived in a place no one should survive.
The Abyss.
It had no name, no logic. Time there stretched like a nightmare. Kazuki lost count of the monsters he killed, the lives he copied, the faces he wore to survive. One rule kept him going: Kill or be erased.
And with every kill, Doppel evolved.
Now, back in a world that forgot him, Kazuki isn't looking for answers. He's looking for a purpose.
Because the Abyss gave him only one truth:
If you can become anything—who will you choose to be?
