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 fight for my strength 
and pride, plain and simple.
حلم للقتال لأجل قوّتي وعزّتي، بكلّ بساطة
ein Traum, für meine Stärke
und meinen Stolz zu kämpfen. Ganz einfach.
un sueño de pelear
con toda mi fuerza y orgullo.
un sueño de pelear
con toda mi fuerza y orgullo.
Un sogno per cui combatterò con forza e orgoglio.
Um sonho de lutar pela minha força
e meu orgulho, simples assim.
мечта бороться за силу
и гордость. Вот так.
