There were devilish men who set cunning traps for the new female teacher, training her into a depraved sex doll to serve as an outlet for their own desires. Unaware of the hell that awaited her, Ayano jumped in, only to immediately catch the eye of Tanjima, the head director with absolute power. The dignified female teacher is drawn into a tragedy, forced into humiliating poses, tormented both physically and mentally, and falls deeper into depravity.
