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...
The whole time I was in the 
water, my heart was dancing.
طوال فترة وجودي في الماء، كان قلبي يرقص
Während ich im Wasser war,
hat mein Herz Freudensprünge gemacht.
mientras estaba en el agua,
mi corazón no dejaba de bailar.
mientras estaba en el agua,
mi corazón no dejaba de bailar.
il mio cuore batteva forte dentro l'acqua!
Meu coração estava dançando o tempo
todo enquanto eu estava na água.
Пока я был в воде, моё сердце плясало.
