Mirko has an athletic build with muscular arms and legs. She has tanned skin, red eyes that slant slightly inward, and straight white hair that reaches down to her waist. On her head are a pair of long white bunny ears that point upwards with a slight curve. Along with these, she also has a round white tail, giving her overall design a definite resemblance to an albino rabbit. After the war against Shigaraki she has 4 prosthetics that replace her two arms, one leg and her severed rabbit ear.
