Kaname Okiura, a student of Prefectoral Umineko Shougyou High ("Umishou" for short), joined the school's swimming club in order to learn how to swim, but the club is filled with weirdos, let alone who can teach him swimming. Then, a sunny, happy-go-lucky girl named Amuro Ninagawa who transferred from Okinawa joined the club. Her extraordinary underwater speed and unorthodox swimming style (plus her personal habit of nude swimming—a powerful magnet to teenage boys) surprised every club member, especially Okiura, because she reminds him of a mermaid-like creature he saw only once in his early childhood.

Kotesashi Kouyou possesses outstanding skill as a masseur. He aspires to become a sports doctor and wants to get a scholarship in medical school.

There he encounters high school girl athletes with various problems. Kotesashi's job is to take care of them physically and mentally and be the hostel manager.

There are twisted tales and twisted tales, but few are as twisted as poor Sado's, who's just realized that he actually likes being made miserable. Of course, knowing that only makes him more miserable, which in turn... well, you get the idea. Desperate to break the circle, Sado volunteers for a special club where he hopes he can work through his issues only to discover that the other members have equally... complex... issues to deal with. For example, the hyper-aggressive club president Isurugi not only has a violent fear of cats, but also believes herself to be a god! Then there's Yuno, who's terrified of men; the Nurse, who forces other people to perform cosplay; and Hayama, Sado's best friend and a compulsive cross-dresser, who's also the girl that Sado is infatuated with.

Tsuda Takatoshi is about to begin his first year in Ousai Academy. His decision to enter Ousai was based upon it being close to his home and he paid no heed to the fact he'd be among the first boys to enter the recently gender-integrated school. On his first trip to school, Takatoshi is surrounded by girls; the train has nothing but girls, the walk to school has nothing but girls and once he finally arrives he is approached by a group of girls and summarily appointed vice-president of the student council and, as expected, he is the only boy there. Now Takatoshi finds himself surrounded by crazy girls who do nothing but horrify him with their candid conversations about feminine hygiene products and, what's worse, assume he's the worst kind of man, the kind who doesn't clean himself and watches porn all day long.
