Ingoku no Houkago

Kudou Souji, originally known as a delinquent, is falsely accused of stealing underwear at school and is suspended. Soon after, Souji becomes the target of slander and scorn from the entire school body, and his girlfriend, Yoshimiya Mafuyu, chooses to break up with him. With a burning desire for retribution against the person who wronged him, Souji uses Minamino Kirie, a class teacher who is also his sex slave, to snoop out the culprit. In truth, Souji is a sexual deviant who has built himself a room in the basement of the storehouse where he lives to discipline sex workers, and he enjoys giving Kirie lewd and lascivious bouts of discipline there. Through Kirie's investigation, he discovers that the mastermind behind the incident was his former lover -- Mafuyu. After successfully taking her to the basement of his home to exact his revenge, Souji vows to do the same to the female students who have become his foes as a result of this incident. Souji's means of retaliation is domination through pleasure -- and in order to achieve this, he is determined to turn his prey into prisoners of debauchery.
