Discipline: Record of a Crusade

The story revolves around Takurō Hayami, a transfer student to a mostly female populated boarding school St. Arcadia. After being admitted because of his sexual powers, Takurō moves into the same dorm as Saori Otokawa, Yuuki Miyagishi, Luli Nonomiya, and Maiko Kaneda, where Yuuki discovers that he has a special capability - an "Ultimate Sex Power," when they have sex in the bath. Having knowledge of Takurō's powers, Leona Morimoto wants him to be part of the Social Club, to which she is the leader of, with the intent of making him her own personal sex slave.

Leona tries to pressure Takurō into joining her group by kidnapping Saori, but with the help of the other girls, she and Takurō are able to escape Leona and her club. After capturing Maiko for her in Saori and Takurō's escape, Leona has her have an orgy with her and some men, where they are no match for Maiko's sexual prowess. As punishment, Leona's sister, Reina Morimoto, the head of the school, has her wear a chastity belt. At that time, a series of sexual assaults has left a number of female students catatonic from pleasure, and it is discovered that an exchange student has been responsible, to which Leona poses a challenge, if Takurō can over come her, Leone will not tear down their dormitory. After Takurō's "victory," Reina decides to test Takurō's sexual powers herself, and gives him high marks.

When Takurō and Saori decide to consummate their relationship, they find they cannot, since all the sexual activity he's undertaken has left him with premature ejaculation. At that time, another member of Saori's club has infiltrated an orgy organized by Reina and Leona, which consists of several select female students being forced to service CEOs' and Politicians. After escaping the orgy, the club member discovers that the Morimoto family blackmails employees to send their daughters to St. Acadia in order to pimp them out to the rich and powerful.

While curing his premature ejaculation, the head nurse tells Takurō that she was rejected by the Morimotos for not being pretty enough, and wants to take them down. As Saori and her friends try to find the blackmail list, she and Takurō are captured, with Saori being given an aphrodisiac, so as to not oppose getting raped. The nurse frees Takurō, who then finds Saori, and they make love after Leona and her goons escape. After leaving their prison, Saori and Takurō find that the blackmail list has been turned unreadable after it got wet from when they used the system to escape, but Takurō's ending narration states that the Morimotos are unaware of that fact.
