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...
I'm here to cheer on the guys 
from my old high school.
أتيتُ لتشجيعكما من مدرستي الثانوية القديمة
Ich feuere hier die Jungs
meiner alten Oberschule an.
Yo animaré
a los de mi vieja preparatoria.
Yo animaré
a los de mi viejo instituto.
Je suis venu soutenir
les nageurs de mon lycée.
Io sono qui per i kohai del mio liceo.
Eu vim para torcer pelos novos
alunos da minha escola antiga.
Я пришёл поболеть за ребят
из моей старой старшей школы.
