The sub-leader of Roushu. Her ability is 'Ice'—she gradually freezes the internal organs of anyone she touches. She has a bright and kind personality but occasionally makes psychopathic remarks. Like Kakuji, she is unconsciously cruel to humans. She is actually stronger than Kakuji, but because she likes him, she yielded the boss position to him.
