The Maus Commander is a medium-sized girl with short brown hair and blue eyes. When not wearing the Kuromorimine Sensha-dō jacket and hat, she can be seen wearing the Kuromorimine school uniform. In battle, the Maus commander is aggressive and easily irritated. She also does not react well under stress, snapping at her subordinates, shaking in fear and even panicking when summoned by Maho Nishizumi for what she perceived as a strategy meeting.
