Koichi is confessed to by a girl named Yukako Yamagishi, who turns violent at the thought of being turned down, leaving behind some of her hair. The next day, Yukako becomes irritated with the class rep after she badmouthes Koichi, using remotely controlled strands of her own hair to burn the rep's hair until Okuyasu saves her. Realising Yukako is a Stand user, Josuke and Okuyasu advise Koichi to act like a terrible person in order to make her give up on him. This tactic backfires, however, as Yukako kidnaps Koichi in order to discipline him into becoming a model man.
