The year is 20XX. With crime on the rise, prisons are at constant saturation. The government has turned to privatizing prisons, introducing a slave system to manage, control, and exploit prisoners. The purpose of prisons is no longer rehabilitation and reintegration into society; they have become experimental grounds where male inmates are trained with aphrodisiacs and commands, turning them into docile sex dolls. Even within this private prison, there is one female guard, Wakasaki Ao, who is rumored to be cold-hearted. A rebellion is about to begin among the prisoners whose human rights have been taken away by Ao through her unreasonable orders and punishments.
