Wenge Kong (nicknamed China by everyone else) is an extremely skilled table tennis player who travelled to Japan to start anew after he was kicked out of his home team in China. Originally his intention was to beat the local hero "Dragon," but he finds new worthy opponents after meeting Peco and Smile.
Smile is a member of the Katase High table tennis club, along with his best friend Peco. Unlike the other members of the club, Smile thinks of the sport as a job or a way to pass time. He does not try to enjoy it for fun and often lets less able players beat him out of consideration for their feelings. The other members of the club ironically nicknamed him Smile because he never does. It is later revealed that the name stems from the first time he smiled after winning a junior table tennis tournament with his childhood friends.
Dragon is the main member of the Kaio Academy table tennis club. He is highly respected by the other club members and is somewhat of a local hero.
