Rin Matsuoka is a student at Samezuka Academy, Iwatobi's rival team.
Rin is a good looking, fairly tall teenager, standing at 177 cm (5 feet, 10 inches). He has short, purple hair and red eyes. Like every male in the cast so far, he is a muscular bishonen. His hair in the CM is styled differently than his hair in the official PV (though this might be because there is a two year gap between the two promos). Rin's teeth are noticeably sharp.
Rin, Haruka, Makoto, and Nagisa were in the same swimming club during elementary school. The group won a relay just before Rin left to study in Australia. The trophy was buried in a time capsule at their swim club. He raced Haruka during a visit in the winter of the first year of middle school and took a devistating loss. He has returned home every New Year, but never made contact with his previous friends.
He previously came back to Japan after studying abroad.
- Rin was originally nicknamed "Pimp (-san, -kun, etc.)" by the fandom as a result of his flirty looking mannerisms in the CM.
- Rin's behavior is different in the PV, compared to the CM. This suggests that something happened while he was abroad, something that changed him from a happy go lucky flirty guy, to a more serious person.
- Fans speculated that he and Nagisa were related because of their similar eye shape and color in the CM.
