Hamaji Youhei, a high school student, spends his days mindlessly lounging around. He can't keep up with his schoolwork, he's terrible in sports, and he can't stick with anything for long. Aside from that, he's a pervert who is always rejected by girls. A sophomore persuades him to join a club where he may lunge at females and fondle and touch them all he wants. As a result, he joined the Water Polo Club. Can Youhei, who never stays committed to anything for long, find his place in this club?
