However, he becomes more serious once he's on the field and even has quite a bad personality, as he states with a smile than Mizuki might not be able to recover if he were to lose twice to the same rival , during Touin's match against Seiseki. Likewise when he said that it was fine to go out of the cage because Seiseki's guys were getting a bit too carried away.
