Synopsis
In the last summer before graduation, Haruka Nanase (voiced by Nobunaga Shimazaki 岛﨑信长), a third-year high school student at Iwatobi High School, finds himself lost and uncertain about his future after graduation. An extraordinary freestyle swimmer, Haruka; however, deliberates from becoming a professional competitive swimmer, because it goes against his beliefs. Haruka sets his mind on swimming the relay at the Nationals for one final time with his teammates Makoto Tachibana (voiced by Tatsuhisa Suzuki 铃木达央), Nagisa Hazuki (Tsubasa Yonaga 代永翼) and Rei Ryugazaki (voiced by Daisuke Hirakawa 平川大辅) of the Iwatobi Swim Club 岩鸢高中游泳部. His teammates notice a change in him, as he seems to have given up on individual freestyle swimming, which he loved. Makoto, especially, is worried about Haruka, but a misunderstanding arises between them, as they draw closer to the Nationals.
