Chuuya Nakahara can come off as blunt, irrational, temperamental, and arrogant. He revels in fights as he loves to show off his ability to other people. He takes great pride in having the best martial arts in the Port Mafia. He shows many signs of being insecure about himself, and despises rude remarks about his appearance. Despite being ruthless, he does not torture when it’s unnecessary. He is able to be reasoned with, despite his short temper. He seldom takes people’s lives for granted.
