Free! Eternal Summer

A year after its creation, the Iwatobi High School Swim Club is struggling to attract new members. With seniors Haruka Nanase and Makoto Tachibana, along with their younger friends Nagisa Hazuki and Rei Ryuugazaki, facing graduation, they must find a way to recruit more members to keep the club from closing. While they work to save their club, Haruka and Makoto also grapple with uncertainty about their future career paths, unlike their friend Rin Matsuoka, who is determined to become a professional swimmer.

The situation becomes more complicated when Sousuke Yamazaki, an old friend of Rin's, transfers to Samezuka Academy. Sousuke's arrival stirs tension between him, Rin, and Haruka, adding to the challenges the Iwatobi Swim Club faces. As they navigate these difficulties, the friends must strengthen their bonds and face the future together, all while pursuing their love of swimming.
