Yuichiro Date transferred schools after a devastating betrayal. At his previous institution, he intervened to stop students raping a female teacher, only for the victim to falsely confirm the perpetrators' accusation that *he* was the assailant. This trauma shattered his good-natured personality, replacing it with profound hatred towards all female educators.

Driven solely by vengeance, Yuichiro arrived at his new school with a calculated objective: systematically entrapping female teachers in sexual bondage. He employed manipulation and coercion, deliberately targeting instructors he assessed as vulnerable. His campaign succeeded in enslaving two teachers before he set his sights on Honoka Todo as his next primary target.

The school itself operated under a disturbing normalcy of sexual interactions between students and faculty. Yuichiro encountered a group of bullying students engaged in routine sexual misconduct. While executing his revenge, he discovered a rival figure pursuing parallel goals who asserted dominance over the campus territory. This secondary antagonist directly challenged Yuichiro, creating intense conflict over control of the environment.

The narrative concluded within the original OVA, depicting Yuichiro's ongoing revenge campaign significantly complicated by opposition from both institutional authorities and this rival perpetrator.
