At a school now ruled by the powerful Morimoto group, the traditional academic environment has been replaced by a strict hierarchy and hedonistic chaos. While new students like Yuuki are lured into illicit encounters in the showers, Reona Morimoto transforms the Social Club into a den of sexual stamina tests and submission. By manipulating both students and faculty, the Morimoto sisters establish their absolute dominance over the campus.
Leona and her associates expand their influence across the academy, shifting their focus from the sports clubs to the culture clubs. After a hedonistic encounter at the Tea Club, Leona asserts her absolute authority as the school's superintendent, punishing those who fail her. The episode culminates in the forced submission of a drugged student named Saori, cementing Leona's total control over the institution and its social circles.
