Black☆Star starts off as rather arrogant, loud, immature and egotistic. Although he fights as an assassin, he prefers to forget the Way of Assassination by shouting and making his presence known, the reason being that he is a massive attention-seeker. He cannot stand having someone else get more attention than himself. His arrogance stems from the fact that he seems to exhibit a superiority complex. He constantly refers to himself as 'BIG' and the other people around him as 'small.'
