Teppei is relatively plain in appearance. He has glasses, black eyes, a somewhat prominent nose, and short, brown hair (dark green in the anime).
He's not quite as belligerent as Seo or Koyama, but he clearly subscribes to the belief that Class E is inferior to him, expressing great shock when he, Class A, or the baseball team loses to them.
- According to the Character Book, Teppei's father is the chief reporter of a major newspaper company, and Teppei takes after him in both pride and his ability to obtain and use information.
- According to the Graduation Album, Teppei finds employment at the major newspaper company, Dokunichi Shimbun.
- He's the announcer during Class E's baseball match and the pole-toppling game.
