Free! Eternal Summer

Four friends dive into summer, battling dreams and doubts to keep their swim club alive.

A year after the Iwatobi High School Swim Club's formation, the roster remains stubbornly thin. Senior swimmers Haruka Nanase and Makoto Tachibana, along with their spirited teammates Nagisa Hazuki and Rei Ryuugazaki, scramble to recruit fresh talent before the school forces the club's dissolution. Their efforts are tangled with the looming reality of graduation, as each member wrestles with the question of what lies beyond the pool. While their old rival Rin Matsuoka now captains the Samezuka Academy team and chases a professional swimming career, Haruka and Makoto drift in uncertainty, unsure whether to follow the same path or forge a different future. Complications surface when Sousuke Yamazaki, a promising swimmer and former acquaintance of Rin, transfers to Samezuka. His arrival reignites old tensions, pulling the three friends into a subtle rivalry that tests both their bonds and their dedication to the sport. As the summer heat intensifies, the swimmers must confront personal ambitions, lingering friendships, and the bittersweet prospect of parting ways, all while striving to keep their beloved club afloat.
