■Takeda Makoto, a perverted and obedient athlete who is in love with ginger seeding

Former swimming coach Hatanaka and his pupil Shin met through the school's club activities. Although Hatanaka became a disciplinary dismissal six months ago, Shin, who worshipped Hatanaka as a leader, pushed to the house of Hatanaka and asked for guidance. However, the guidance in the field that lived a rough life progressed in a distorted direction. In front of a truly trained body, Hatanaka repeats the obscene act called training, but sincerely accepts such action in the field and blooms Mazo's talent.
