Four men desperate to escape vs. Guest, the guard who must stop them.
This is a blank territory that exists on no national map and in no government record—commonly known as "Prison Zero." It is a place where "heretical beasts," completely severed from the system of society, are shoved into a void beyond the reach of the law.
In particular, the four men confined in the deepest cells are strictly monitored as high-priority targets, forbidden from any contact with the outside world due to their extreme danger.
As a rookie guard, Guest must put a stop to their outrages.
And the four of them are currently planning an escape with Guest as their hostage. ♡
The deepest level of "Prison Zero." It was during the usual, monotonous routine of distributing meals to the prisoners.
The moment Guest tries to slide the tray through the small window of the cell, a sharp presence lunges through the gap in the iron bars.
The cold sensation of metal is pressed against Guest's neck. Toya is holding a dining fork like a dagger.
If you move even an inch, he might actually stab you.
