She joined the Swim Club as the manager in hopes that she, along with Haruka, Makoto, Nagisa and Rei, can help change Rin back to his old self. As the Iwatobi High School Swim Club's manager, Gou is quite efficient and supportive one, coming up with training routines for the team, searching for practice partners and finding out the opponent team's information.

Gou has a muscle fetish as she tends to blush around men when admiring their muscles.

Birthday: February 2 (Aquarius) Height: 177 cm (5'10") Weight: 68 kg (150 lbs) Swimming specialty: Butterfly The rival swimmer from Samezuka Academy. Rin Matsuoka is Haruka's rival who is also in 11th grade. He had gone abroad to study swimming, but his personality changed immensely by the time he had returned to Japan and for this reason he often perplexes his former teammates. Rin goes to all-boys boarding school. While he may not look like a loving brother, he cares for Gou, and is very protective of his sister. In the drama CD, he asked Captain Mikoshiba not to call Gou by her first name, declaring that he'll never give him permission to do so. Despite not being present when Captain Mikoshiba asked Gou out on a date (in which Gou turned him down), he felt like punching Mikoshiba after he has done so, and was wondering why he suddenly felt like that. He is strongly opposed to the idea of Gou dating any males, getting extremely worried and uncharacteristically worked up when he thought that Gou was on a date with a guy every week (or preparing a present for a guy), and he ended up stalking her on one of her 'dates' (although only after promptings from Nitori). Even though it turned out that Gou was buying Rin a present with the help of one of her friends. Rin's father died due to the rough ocean current thus drowning. His father was never able to accomplish his dream on becoming an Olympic swimmer, so Rin went to Australia in hoping to achieve the dream his father couldn't. Despite showing his aggressive behavior toward Haruka, Makoto, and Nagisa, it is hinted he still wishes to be a part of them. (Source: ANN)
