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...
We'll just have to look forward 
to seeing what he transforms into.
سنتطلّع قدماً لرؤية ما الذي سيتحوّل إليه
Wir dürfen uns darauf freuen,
in was er sich noch verwandeln wird.
Habrá que esperar
a ver en qué se transforma.
Habrá que esperar
a ver en qué se transforma.
Oui, mais le plus palpitant,
c’est d’imaginer en quoi.
Quale sarà la sua forma finale
Só precisamos observá-lo
para ver no que se transforma.
Нам лишь остаётся смотреть,
во что он превратится.
