Kenko Zenrakei Suieibu Umisho
Kaname Okimura, a student of Prefectoral Umineko Shougyou High ("Umisho" for short), joined the school’s swimming club in order to learn how to swim, but the club is filled with weirdos, letting him alone teaches himself to swim. Then, a sunny, happy-go-lucky girl named Amuro Ninagawa who was 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 Okimura, because she reminds him of a mermaid-like creature he saw only once in his early childhood. With much expectation, she joined Umisho, with Amuro in the team and many other members Umisho now aims towards the Katou Tournament, and eventually the inter-highs. GO UMISHO!
