At first glance, Chuuya seems to be a temperamental, rather arrogant, and sometimes rude person.  He enjoys fighting and is happy to have the opportunity to demonstrate his fighting abilities, and is also very proud of his reputation as the Port Mafia's strongest martial artist.  The mocking remarks are coupled with his pride, as he is not afraid to ridicule his opponents mid-fight.  As befits a member of the Executive Committee, he does not hesitate to eliminate the enemies of the Port Mafia.
