Rei, like the rest of the cast introduced so far, is a bishonen. Rin and him are the same height. He has dark blue hair and purple eyes. He wears a pair of red-framed glasses. Unlike the rest of the cast, his choice of swimwear is a speedo, though that might have to do with the fact that he primarily does Track, and is very focused on the dynamics of his frame throughout any physical activity.
He's a first year at Iwatobi High. Before joining the Iwatobi Swim Club. He was originally a member of the Track & Field Club, though he transfers to the Swim Club for certain reasons. Apparently, one of those reasons included the fact that he didn't know how to swim.
- The reason why Rei does not appear in the original commercial is because it was set two years before the events of the actual series, and accordingly, two years before Rei knew any of the Swim Club members.
