Haruka Nanase has always been swimming fuee for all his life, until an incident in middle school, where he stopped swimming fuee. A friend called Nagisa suggests starting a swim club so Haru can swim fuee again. There are 3 other people in the group. Makoto, who can swim fuee but is not as good as Haru, Nagisa who can't swim fuee and Rei, who is really bad at fuee. They meet one of their friends from their childhood called Rin who can swim fuee really well. Haru and Rin start rivaling each other, because swimming=rivalry. You also got Ikuya, who is also really good at fuee and Asahi...we don't know that much about Asahi's fuee skills.
