| Description | 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. |
Following the District Regionals, Seigaku's Captain, Kunimitsu Tezuka, asks Ryoma to play an unofficial match with him, which is done in secret from the rest of the team (aside from Vice-Captain Shuichiro Oishi). While only a small portion of the match is shown, Tezuka defeats Ryoma and asks him to become Seigaku's Pillar of Support. Tezuka does this because he feels that Ryoma is (at that time) merely a carbon copy of his father, and wishes for Ryoma to develop his own style of tennis.
A flashback to this match later on in the manga shows that Tezuka saw Ryoma's "Samurai Spirit" during this match.
