Ranma breaks up another one of Happosai's panty raids, and Happy takes his revenge by slipping Ranma a Shujyugan Obidience Pill. The pill has a strong magnetic attraction and causes Happosai and Ranma to stick together. The two are inseparable unless the pupil (Ranma) defeats the master (Happosai). Happosai refuses and dodges all attacks Ranma throws at him. Finally, Ranma enters the girls' locker room and covers Happosai so he can't see them changing. Happosai throws a fit and crashes into the boys' locker room, and Ranma easily defeats the horrified Happosai and the two are separated.
