Hatanaka, a former swimming club coach, and Makoto, his student, met through club activities at school. Although Hatanaka was dismissed six months ago, Makoto, who worshiped Hatanaka as a leader, rushed to Hatanaka's house and asked for guidance. However, Hatanaka's guidance, which led a rough life, goes in a distorted direction... Hatanaka repeats obscene acts called training in front of the true body that has been toughened, but Makoto happily accepts such behavior of Hatanaka and blooms his masochistic talent.
