After demonstrating "sex education" to the Kendo Club, Hajime turns his attention to Sakura's mother, Tsubaki. By manipulating her into believing that providing a live demonstration of conception is a mother's duty to her daughter, Hajime seduces Tsubaki and eventually draws Sakura back into the fray. The two women quickly succumb to his influence, competing with one another to conceive his children and surrender completely to his dominance.
