178cm tall, wearing a long black skirt, a light green suit with a black tie, and a monocle. She is characterized by her white hair tied in a ponytail. She is the principal of FPE, a school where students who fail are killed by the teacher in charge of that subject (though she doesn't do the killing herself, perhaps to maintain her dignity). She remains calm and fearless in any situation. She has black horns on her head. She is 40 years old but looks very young for her age (appearing to be in her early 30s). As a side note, her arms and legs are black, except for her head.
