Rin, now living in Australia, trains hard every day with swimmers from all around the world. Then a Japanese guy shows up where his team is training, challenging each of his teammates to races and beating them one by one. Even Rin is surprised when this newcomer reveals his identity...
You might end up being my 
little brother's rival, then.
قد تصبح منافس أخي الصغير في النهاية إذاً

Entonces, podría terminar
como rival de mi hermano.
Entonces, podría terminar
como rival de mi hermano.

sendo o rival do meu irmão mais novo.
Тогда ты можешь стать
соперником моего младшего брата.
