“From the second I lead eyes on him, Rin's been my hero.”
— Aiichiro to Sosuke, about Rin.

RinTori is the slash ship between Rin Matsuoka and Aiichiro Nitori from the Free! fandom.


Nitori is Rin's roommate in his first year with Samezuka. He has a tendency to follow Rin around and call him 'Senpai!'. During the first season, he was a vital teammate who helped Rin get back on the right track when he was going down a bad path. Even though Rin yelled at him, he followed him along and admired him. During Rin's isolation from his former friends, Nitori was the only person who would hang around him and try to reach through to him.

Nitori admires Rin badly, and can sometimes be jealous of the relationship Rin has with Haruka and the fact Rin calls Haruka 'Haru'. However, at the end of the first season Rin calls Nitori 'Ai' (his first name), which makes Nitori feel like a real teammate and friend.

In season two, Rin is no longer Nitori's roommate and the two of them interact less. However, Nitori still receives advice from Rin and talks about how much he admires Rin to other characters.

  • The director of Free!, Hiroko Utsumi, commented that, if you left Rin alone, he would be isolated without anyone, so there needed to be a character — more like a conversation partner — who would draw him out. The character who had been born out of this need was Aiichiro. Aiichiro's role was to draw out Rin’s heart. Because Rin could understand parts of Aiichiro that were like himself, he felt like talking to him.
  • Rin made Aiichiro the swim team captain after he left.
  • Rin's animal is a great white shark, while Aiichiro's is a duck.
  • Rin swims butterfly and freestyle, while Aiichiro swims freestyle and breaststroke.
