Yamabuki Middle School (私立山吹中学校 Shiritsu Yamabuki Chūgakkō) is a national caliber team that bases their strategy on two National caliber doubles teams, supported by the National caliber Singles player Sengoku. They try to use those three weapons to defeat opponents before the matches get drawn out. When their strategy was foiled in the previous year by Seigaku's Tezuka defeating Sengoku, they recruited a second dominant singles player Jin Akutsu, with the aim to eliminate that weakness. Yamabuki's regular sports uniforms are green jackets with yellow stripes with hoods, shirts of the same design, white shorts, and green warm-up pants.
