She is an accomplished swordsman her preferred weapon is a spiritual sword forged to specifically fight divine class spirits. While it cannot wound humans it can still make them feel the pain of getting cut demonstrated when she stabs Makoto. A weapon well suited for her morals and sadistic nature.
