Hantsu x Trash

High school student Yhei Hamaji is viewed negatively since the females don't like him. He is persuaded to join the school's water polo team by perverted upperclassman Nakajima on the grounds that they get to practice together as a coed squad and are free to touch each other as much as they like. Chisato Hagiwara, the girls' star player, berates Hamaji, but because she is one of the females who genuinely cares about him, he develops a crush on her. Then, in an effort to gain her affection, he starts to take water polo seriously.
