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...
If you can swim freestyle the 
way you just did, we can win.
إذا سبحتَ سباحة حرّة بنفس الطريقة
التي سبحتها مؤخّراً، يمكننا الفوز
Wenn du so wie gerade Freistil
schwimmst, packen wir das.
Si nadas como hace rato, podemos ganar.
Si nadas como antes, podemos ganar.
Vu ton crawl, on devrait gagner.
Se riuscirai a nuotare come poco fa, 
la vittoria sarà nostra.
Se você conseguir nadar como
nadou agora, nós podemos vencer.
Если поплывёшь так же,
как только что, мы победим.
