Mira is a Neighbor woman of medium stature with short, curled burgundy hair and eyes. She has chin-length hair styled in a bob cut, with short spiraling bangs framing the sides of her face and shorter, straight bangs covering her forehead. Like all other Aftokrator Neighbors, she has two horns on her head, hers being short and goat-like. She wears a black-and-red coat, short black daisy dukes, and also black transparent pantyhoses. In the past, she had longer hair. She is the only member in her expedition force not to wear a cloak, possibly due to not being supposed to be in battle.

(To Enedra.) "Such a tragedy. You were a brilliant kid. Goodbye, Enedra."

Sometimes the hand Mira uses to hold Speiraskia changes for no reason. For example, in Chapter 72, it is hovering over her left hand when she retrieves Vorvoros, but in the next page, it is floating over her right hand.
