The Iwatobi Swim Club heads to Tokyo for the national tournament that Rei and Nagisa are participating in. Rei is quite nervous, but an unexpected reunion with someone from his past gives him courage... Later, when he stands at the starting block for his race, his bonds with all of his teammates, old and new, bring him back to himself. And so ends Nagisa and Rei's last summer as high school swimmers...
He was already drawing attention 
as a butterfly swimmer,
،كان يلفت الانتباه سلفاً كسبّاح فراشة
Er hat beim Schmetterling
schon für Aufsehen gesorgt,
Ya llamaba la atención nadando mariposa,
Ya llamaba la atención nadando mariposa,
Il attirait déjà l’attention

All'inizio si era specializzato nello stile farfalla,
Ele já ganhava atenção no nado borboleta,
Он уже привлекал
внимание как пловец баттерфляя,
