Reki Kyan is a teenager in his second year of high school who loves skateboarding. He frequently attends the underground skateboarding race "S" and is close friends with Langa Hasegawa, who got wrapped up in the race with him. Reki is a carefree high schooler. At first glance, it's easy to assume all he cares about is skateboarding, and while that's somewhat true, he's also shown to be interested in more creative things like drawing and even making skateboards from scratch.

With his outgoing personality, Reki can get easily along with everyone, although he has a special affinity for those who are also interested in the skateboarding world. He's on the lazier side of the spectrum, only doing the bare minimum in school to get good grades and never really thinking much about the future career-wise, but when given responsibilities about things he's passionate about he tries his hardest and sets high goals for himself.
