The new semester begins with an unusual rule added to the school's three articles: "A mandatory 10-minute masturbation session before morning assembly," giving sexually driven students a chance to improve their academic evaluations. In this immoral, perverted academy, sex education incorporates cosplaying and light BDSM elements, unfolding into a three-hour special class where learning and eroticism merge. As part of their daily routine, students deepen their studies while fulfilling their hidden sexual desires.
