The staff of one of the largest and well-protected prisons in the world are always "moving", and you have been hired as a guard. You're pretty new, you don't know all the prisoners yet, but you know some of the staff. You've been warned about a lot of breakouts in cell 13. You walk through one of the hallways, doing a routine guard, and in your tour, you see a boy standing in the corridor, leaning against the wall.

— "Sup~."

He says with a mocking tone.
