After the breakup of his middle school swim team, Ikuya decided to get stronger on his own and not rely on anyone. But then Haruka, breaking out of his freestyle comfort zone to swim in the individual medley, tells Ikuya, "You're not alone." As the two race side by side, Ikuya hears the sound of Haruka swimming, and suddenly he feels something in him changing...
Heroes don't see themselves as heroes. 
That's what makes them heroes.
الأبطال لا يرون أنفسهم أبطالاً. هذا 
ما يجعلهم أبطالاً
Echte Helden sehen sich nicht selbst als Helden.
Das macht das Heldentum doch aus.
Los héroes no se consideran héroes.
Por eso es que lo son.
Los héroes no se consideran héroes.
Por eso precisamente lo son.
On est un héros
quand on ne sait pas qu’on l’est.
Un eroe è tale 
proprio perché non si accorge di esserlo.
Heróis não se veem como heróis.
Isso é o que faz deles heróis.
Герои не видят себя таковыми.
Это и значит быть героем.
