Makoto and Nagisa watch with their breaths held as Haruka and Rin engage in an intense race.  However, they notice that Rin appears to be have changed. At the same time, Nagisa prepares to start up a swim club with help from Rin's sister Gou.
I swore to myself that I'd 
never put on a swimsuit again!
Ich habe mir geschworen, nie 
wieder einen Badeanzug zu tragen!
J’ai juré de ne jamais remettre 
de maillot de bain !
Mi sono ripromessa che a nessun costo
 avrei indossato di nuovo un costume!
Eu jurei pra mim mesma que eu 
nunca mais vestiria um biquíni!
Я поклялась себе ни за что
больше не одевать купальник!
