Sister-figure of Kagura Tsuchimiya who turned evil because of the power of the sesshoseki. Also, she was the person who killed Kagura Tsuchimiya's father. She was killed by Kagura herself and has turned completely evil in her afterlife. She was extraordinarily talented when alive and slaughtered over 70 ministry agents by herself, and defeated the head of the Tsuchimiya clan and his spirit beast, Byakuei. As an evil spirit, she becomes even more powerful.
