Rin Matsuoka (松岡 凛 Matsuoka Rin) is one of the main characters of the anime series Free! and the light novel High☆Speed!. He was the freestyle and butterfly swimmer on Samezuka Academy's swim team. After Seijuro Mikoshiba graduated from Samezuka Academy, Rin became the new captain and he is currently training with a professional coach in Sydney, Australia.


Rin Full

Rin is a muscular young man with semi-long, maroon colored hair, red eyes and shark-like teeth. His fall and winter school uniform consists of white trousers, a black t-shirt, a buttoned up white jacket and black shoes. During the spring and summer, his uniform consists of white trousers, a black polo with a pink collar, and black shoes. When swimming in competition, he wears black, long-legged swimskins with a red pattern. His school bag is a red messenger bag with the word "shark" printed on the outside. He is often seen wearing a baseball cap.


When young, Rin displays great passion and competitiveness for swimming, as well as teamwork.[5] As years passed, his ideals about swimming drastically change and he doesn't care much about the relay trophy he won during elementary school, becoming obsessed with competing and winning against Haruka Nanase.[5][6]

As a student at Samezuka Academy, he observes the Iwatobi High School Swim Club practicing and having fun together and is notably morose when he sees how happy they are together while he stands alone.[7][8][9] His isolation, however, is self-imposed due to his taking on the goal of meeting his deceased father's dream of becoming an Olympic swimmer.[10] At times, Rin displays a softer side, showing concern for his friends' well-being and acting as a mentor towards Gou Matsuoka (Rin's younger sister) and Aiichiro Nitori (Rin's temmate) [8]. Following graduation and beginning his training with Mikhail Makarovich Nitori in Australia, Rin seems to relaxed and playful, bringing his friends Australian souvenirs and sharing jokes with Sosuke.[11]


Toraichi Matsuoka (Rin's father) is a fisherman by trade who died during a storm that claims his life and his crew only three kilometers from shore when Rin was very young. Rin states that he has very few memories of his father and cannot even recall what his father looked like as he would be gone for days while at sea. Rin wants to become an Olympic swimmer because he believes that by following this path, he will be able to remember his father's face.[10] He also puts his swimming goggles in the same way his father used to do, by pulling the strap back and letting it snap onto the back of his swim cap.[6][10][12]Rin joined the Iwatobi Swimming Club in elementary school because that was his father's old swim club, where his father and his teammates won a relay. Rin wants to make a team and win a relay to emulate his father as he starts down the path to becoming an Olympic swimmer.[1]

Young Rin

"...I'll show you a sight you've never seen before!"

In elementary school, Rin is in the same community swimming team with Haruka Nanase, Makoto Tachibana and Nagisa Hazuki and he is instrumental in motivating the group to swim a relay. After winning the tournament, he leaves Japan to attend a school in Australia known for their strong swimming team.[1][13][12]

Rin enjoys swimming, but finds attending school and living in Australia to be a big adjustment. His homestay parents, Russell and Lori, are kind people who care for him and help him, even buying him a dog they name Winnie to ease his loneliness.

Rin graduates high school and returns to Australia to swim with a multi-national team there. He begins training with Mikhail Makarovich Nitori, a former professional swimmer and current professional swimming coach. He meets and gets to know Natsuya Kirishima, who informed him that he should watch out not only for Haruka, but his own younger brother Ikuya Kirishima as a rival for swimming glory. Rin returns to Japan to participate in the All-Japan Invitational, a competition that determines who will move on to compete on the global level. Rin qualifies by winning the 100m butterfly event.
