At the beginning of the series, 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, and will proceed to beat down anyone more popular than him so he can be popular again. His loudness is often shown in his tendency to often shout when he speaks and his trademark cries of 'Ha Ha!' or 'Yahoo!' By this point, he is much kinder and sincere to others, but can still be very immature.
