Similar to other werebeasts, Izuna has a combination of animal and human traits, with her having fox-like ears and a fluffy tail. She has dark purple hair and chestnut eyes (black hair and black eyes in the light novel). Her pupils are vertically slitted, similar to those of a cat. When Izuna uses her "Blood Destruction" ability, she grows a longer tail, and all fur from her body turns red. She also has a red symbol on her forehead.
