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...
A dream to take on the 
world with you someday.
حلم مواجهة العالم معك يوماً ما
Der Traum, mit dir eines Tages
die Welt herauszufordern.
De tomar el mundo contigo un día.
De tomar el mundo contigo un día.
J’aimerais t’affronter
aux Mondiaux.
Quello di combattere con te
sul palcoscenico mondiale.
Um sonho de conquistar o
mundo com você algum dia.
Мечта попасть однажды в мир с тобой.
