Released on year:2014
Despite the fact that the Iwatobi High School Swim Club has been in existence for a year, new members have yet to join. Haruka Nanase and Makoto Tachibana, along with their younger friends Nagisa Hazuki and Rei Ryuugazaki, are now senior students and must find a way to recruit new members. Otherwise, due to a lack of membership, the club will be forced to close the following year.
Meanwhile, with graduation approaching, seniors must make decisions about their future plans. Unlike their friend Rin Matsuoka, the new captain of the Samezuka Academy Swim Club, who is adamant about pursuing his dream of becoming a professional swimmer, Haruka and Makoto are undecided about their future careers.
When Rin's old friend Sousuke Yamazaki arrives in the city to study at Samezuka Academy, the newly scouted swimmer's arrival causes tension in the relationship between him, Rin, and Haruka.
