Shimogami University Swim Club

Shimogami University Swim Club Members include:

The Shimogami University Swim Club is a university-based swim club that helps competitive swimmers continue to develop their skills while participating in inter-collegiate tournaments, as well as preparing to compete for a place at the All-Japan Invitational, where the top two swimmers in each event are granted permission to compete at global-level competitions.

The club successfully recruits Ikuya Kirishima and Hiyori Tono onto its team. Upon seeing Ikuya at a university-level tournament, Haruka Nanase tries to restore contact, but is rebuffed. Ikuya seems annoyed and Hiyori forbids the junior high school teammates access. Even with the help of Makoto Tachibana and Asahi Shiina, Hiyori is dismissive and even rude to the three former friends without good reason.

Over time, each one resolves his misunderstanding with Ikuya and makes amends. It is also revealed that Hiyori has been left on his own to care for Ikuya's fragile health and training while Natsuya travels the world earning free-lance competition money. Finally, after being rejected by Rin Matsuoka's coach (Mikhail Makarovich Nitori) in Australia and getting some sound advice from best friend Nao Serizawa, Natsuya returns to Japan and releases Hiyori of his burden and apologizes to both Ikuya and Hiyori. Ikuya is then free to resolve his own issues with Hiyori and re-connect with his former teammates.
