Haitoku no Kyoukai

Kisaragi Miyuki projects an aura of absolute authority. Cool, overly serious, and perpetually stoic, she maintains a strict distance from her students, refusing to tolerate jokes or casual familiarity. To the outside world, she is an unapproachable educator who commands respect through sheer severity. However, whispers circulate among the student body suggesting that her rigid professional demeanor masks a startlingly different reality. According to these rumors, away from the school grounds, Miyuki transforms into a clumsy, scatterbrained woman entirely unlike the imposing figure standing at the front of the classroom. This intriguing contradiction captures the attention of Miwa Itsuki, one of her students. Possessing a deeply problematic personality, Itsuki harbors a compulsive urge to tease women he perceives as flawed or hypocritical, and his teacher’s rumored double life presents an irresistible target. The opportunity finally arises when he spots Miyuki shopping at the convenience store where he works part-time. Confronted with the chance to witness her unguarded private persona firsthand, Itsuki finds himself unable to suppress his sadistic tendencies any longer, setting the stage for a tense and boundary-pushing encounter between student and teacher.
