Shusuke Fuji

Fuji is known as a tennis tensai (genius). He's extremely famous among all the tennis players in the region. Fuji's skill is right behind Tezuka's. He also has a brother who goes to a different tennis school, mainly because he didn't want to be compared to his big brother - Fuji, who's already known as the tensai player at Seigaku. Fuji is always smiling no matter in what situation, this gives him a really friendly appearance, although in fact, Fuji is a deadly strong tennis player that most Junior high players should pray to never meet in the court.

Shūichirō Ōishi

Oishi is a really kind person who cares about all the other team members twice as much as a regular team member (according to Fuji). Oishi is a Tezuka's close friend and is the vice captain of Seigaku. He plays doubles with Eiji, together, the two of them are known as the undefeated golden pair who went to the nationals.

Golden Pair

Oishi, as a doubles partner he is the perfect complement for the acrobatic Eiji. Oishi is a doubles specialist and is perhaps one of the best doubles players in the series.

Tezuka Kunimitsu

Tezuka is the captain of Seigaku. He's well respected by all the teammates and also by the players in other top tennis schools. Tezuka also made it into the regulars as a freshmen, now he's in his third year and is about to graduate. Tezuka sees great potential in Echizen and taught Echizen the meaning of playing tennis by having a match with Echizen despite his arm injury. Even though Tezuka never smiles, he appears to be extremely popular among the female fans.

Ryoma Echizen

Echizen is the featured tennis player in the show. His father is a famous professional tennis player who retired really early but otherwise could have became the number 1 tennis player in the world. Echizen is the only 1st year regular player in Seigaku, since he short compared to the other members, he's been nicknamed O'Chibi (baby boy) by fellow player, Eiji. Additional info worth noting: Echizen grew up in United States and knows English very well (many classmates admires him for this).

Sumire Ryuzaki (竜崎 スミレ Ryūzaki Sumire) is the coach of Seigaku's tennis club, as well as one of the school's math teachers. She is the grandmother of Sakuno.
