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...
You know, being able to swim with 
all of you guys for all these years
السّباحة معكم جميعاً طوال هذه السنين
Wisst ihr, während ich all die
Jahre mit euch geschwommen bin,
Poder nadar con ustedes
todos estos años
Poder nadar con vosotros
todos estos años
Vous savez,
je me suis éclaté comme un fou
Sapete, aver potuto nuotare insieme a tutti voi
Sabe, ser capaz de nadar
junto de todos vocês esses anos
Знаете, возможность
плавать с вами все эти годы
