The second OVA adaptation of Yoshiyuki Uba's Harem Cult, an adult academy role-play about an information war between a corrupt student council and its enemies. In Harem Cult 3: punish your crime, faculty adviser Ringo Mashiro identifies herself as a collaborator and informant for the Punisher, enemy of the Student Council Union controlling private Karin Academy. She invites Tatsumi, chosen as Hatorishima's second collaborator, to an explicit private lesson in the counseling room. In Harem Cult 4: If Words Can Kill — Hotori, Hatorishima and Tatsumi are captured in a ruin. Delinquent ringleader Hotori questions Hatorishima's reasons for opposing the council and challenges him to a one-on-one contest for dominance. The rule first states that touching Tatsumi means defeat, then shifts until surrender itself determines the loser.
