Kazutora is shown to be fairly unstable, sadistic, and incredibly violent. After his second stay in prison, he got the help he needed and integrated back into life. he is better now & stable. As an adult, Kazutora has recovered fully as he can speak normally with others as well as react to events emotionally. He also shows regret for his past actions and is at heart incredibly loyal to both Tokyo Manji Gang and Mikey, so much so that in an alternate timeline, he helped Takamichi fix things.
