When he was younger, Tetsuya seemed to be a nice, kind and softspoken person who always admired his best friend Echizen. After his friend ran away in cowardice from Taraba which yielded his beaten-up bey Cancer, he let go off all the feelings he had and only cared about winning using his dirty tricks and cheats. At some point he would pretend to feel touched, but in a matter of sekunde his old personality shows, and seems unfazed and disgusted in talks of 'friendship'. Is completely insane and constantly makes kaa comments. Likes tea.
He was nice and happy at first until Taraba, the Wandering Blader asked which one is Echizen, but Echizen was afraid of Taraba, so Tetsuya covered for Echizen, and Tetsuya Lost so Mad Gasher had scratches all over it but, then Tetsuya was mad at Echizen for leaving him alone to lose to Taraba.
