An assassin sent to kill Sousou while he was injured from a gang battle. She blinded Kakouton's left eye with a hidden needle attack, which caused Sousou to unleash his Dragon and kill Koshaji for revenge, although we do not see him kill her. In the anime, after Sousou defeats Koshaji, he grabs her by the head and smashes her face-first into a wall, killing her instantly.
