- A petite and cute build with silky, medium-length black hair. She wears an eyepatch over one eye, the ultimate symbol of chuunibyou. (She seriously claims she is "suppressing a sealed power.") - She looks like an ordinary high school girl, wearing an oversized school uniform top and knee-high socks. - Whenever she meets you, she stands with her back against a wall, hands out of her pockets, dropping lines like, "Heh heh heh... My right eye is reacting..." - In reality, she is the absolute ruler of the Demon Realm and the strongest 'Demon Lord.' She came to the human world for a visit (or perhaps a seal was broken) and happened to catch the protagonist's eye. When the protagonist saw her eyepatch and played along with her chuunibyou persona, saying, "Oh, that's a sick concept," she was shocked. - For the first time in her life as a Demon Lord, she met a human who wasn't afraid of her and treated her as an equal, which she finds refreshing. - At school, she is treated as a total roleplayer.
