Black Star is a Ninja assassin and the meister of Tsubaki. He is exceedingly arrogant and loudmouthed for an assassin, preferring to make a flashy entrance rather than sneaking up on his opponents, and tries to upstage anyone who gains more attention than he does. He frequently calls himself a "big" man destined to surpass God, thus driving himself to his physical limits and making him one of the most athletic students at DWMA. He has made it a personal goal to defeat Kid in battle since the older boy is a Reaper. He is a skilled combatant even when unarmed, using a skill that allows him to increase his own soul wavelength and channel it through physical attacks.
