Rokkaku Jr. High

Oji (I never knew his name) is the coach of Rokkaku. He is a wood worker from his early years up to present. He was the only one who created the playground near Rokkaku Jr. High, because of this children come to playing tennis the natural way. He's very unpredictable in everything, although, he's always deciding for the best.

Aoi Kentaro is a freshman at Rokkaku and at the same time, the tennis club Captain which is highly unusual. He has a very loud voice even when talking normally and he's easily excited when playing tennis. A passionate guy and has a great sense of control in tennis. He defeated Ryoma's Drive B and owns a hexagonal-shaped racket with hexagonal gut.

Saeki Koujirou is the vice-captain of Rokkaku's tennis club. He's a childhood friend of Fuji Syusuke. Has a great sense of playing tennis and at the same time has a keen eyesight when it comes to reading the opponents mannerisms that determine the action they'll be doing next.

Kurobane Harukaze or Bane-chan is the doubles partner of Davide. He specializes in strong serves. He's always the one who hears Davide crack some corny puns and takes it into himself to be the one to beat the crap out of Davide's corny puns by smacking Davide on his head or kicking him somewhere else. He's also great with kids.

Davide or could also be spelled "David" (I'm not sure, but I'm going with how the Japanese seiyuus pronounce it) is the doubles partner of Kurobane. He owns a long racket. He also defeated 100 Hyotei players which is quite a feat. You would always see him cracking some corny puns to lighten up the mood although he's always being kicked/slapped by Kurobane after cracking a terrible pun.

Itsuki Marehiko or Itt-chan is a very amusing player. Always breathing out through his nose and always asking anyone within hearing range, "nande nande?" or "why? why?". His specialty is to hit balls without any spin, therefore, sealing moves like Tsubame Gaeshi which needs some amount of spin.
