- "You think you got me huh!?"
- ―Tetsuya fighting Ryo in Dobuita
Tetsuya acts like a thug, but in reality he isn't very strong at all, so he tries to always stick with Enoki or Goro Mihashi. Despite this, he has recently begun to think seriously about his life and doesn't like what he is becoming, so he intends to sort himself out and start fresh after he graduates from high school.
