Leona Miyamura is the older sister of Toranosuke Miyamura. Leona is a fairly tall girl with butt-length silvery-white hair that is tied at the bottom by a pink bow with a single hair strand hanging across the right side of of her face, red eyes, a slender built body and large breasts. Her apparel consists of a long white shirt over her underwear, which she seems to wear all the time at home, even after her problem with the seventh witch is solved. In the past, her attire consisted of the Suzaku high uniform. She also wears a ribbon that ties her hair into a small ponytail, as well as an apron when cooking at home. She has an abstract and cold personality towards people around her and is prone to inflicting violence on those who come around her. She is also seen as crazy by Yamada, but she really care for her brother as when she thanked Yamada for being Toranosuke's friend and refused to get her brother mixed up in the witches. She was fearful of returning to campus and experiencing the events of the seventh witch's power, not wanting to become the person she was before discovering witches.
