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...
Come to think of it, the high school 
nationals are tomorrow, aren't they?
على ذكر الأمر، البطولة الوطنيّة للمدارس
الثانوية تبدأ غداً، أليس كذلك؟
Ach ja, die Nationalmeisterschaften
der Oberschulen starten morgen, oder?
Ahora que lo pienso, el nacional
de preparatoria es mañana, ¿no?
Ahora que lo pienso, el nacional
de secundaria es mañana, ¿no?
D’ailleurs, le National des lycées
a lieu demain.
Piuttosto, domani ci sono le nazionali 
per gli atleti liceali.
O que me fez lembrar que amanhã é a
disputa do nacional do ensino médio, não?
Кстати об этом, завтра
национальные старшей школы, да?
