Following a failed attempt at collecting the 99 souls of mobster Al Capone and his men, assassin Black Star and his weapon Tsubaki track them down to the residence of the witch Angela, only to find they have all been killed by Angela's bodyguard Mifune. Black Star fights Mifune, but is easily beaten due to his lack of skill as an assassin. When Mifune insults him, however, Black Star accuses him of trying to upstage him and successfully utilizes a surprise attack that defeats him. However, Black Star decides not to kill him or Angela once he discovers the witch to be a helpless young girl. In addition, he declines collecting the mobsters' souls since he himself did not defeat them.
