Ryunosuke Tanaka!

As a teenager, Ryūnosuke was of average height for his age and was quite thin. He has a considerably muscular physique with highly defined abs. He has a shaved head, accompanied by his grayish-blue eyes - although in the manga they look golden brown -, which gives him the appearance of a juvenile delinquent. His complexion is fair and he is almost always found making strange faces to try to scare or intimidate those who bother him or his opponents in the middle of matches.

He is an airhead and is always yelling, plus it is easy to make him angry at anything. Despite that, deep down he is a good person: he cares about the games and his teammates, he is usually friends with everyone and is considered someone fun and crazy. He also gets easily excited when someone younger than him calls him "senpai." On the other hand, he has the tendency to take off his shirt every time he wins or scores a point.
