Brandish Mu is a young woman with striking green hair cut into a bob with bangs above her eyes, accented by two purple cross-shaped ornaments on her head and silver cross earrings. She wears a gold-colored bikini that reveals her generous bust, paired with a golden coat patterned with purple-indented flowers and a fluffy purple collar. Her demeanor is typically calm and logical, preferring to avoid unnecessary conflict, though she can be quite waspish when irritated. Despite her laid-back exterior, she has a surprising soft spot for fluffy things and is utterly fearless in the face of danger or interrogation.
