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...
If they keep improving, they should 
really be going places by next year.
إذا ظلّا يتحسّنان فينبغي أن يقطعا
شوطاً طويلاً مع حلول العام المقبل
Wenn sie sich noch weiter verbessern,
sollten sie nächstes Jahr aufs Treppchen kommen.
Si siguen mejorando,
llegarán lejos el próximo año.
Si siguen mejorando,
llegarán lejos el año que viene.
S’ils progressent encore,
ils iront loin, l’an prochain.
Di questo passo,
Se continuarem melhorando,
devem chegar longe no ano que vem.
Если продолжат совершенствоваться,
к следующему году многого добьются.
