A 14-year-old student at the school with pretty average magical talents and grades to match. She's the type who genuinely hates violence and the idea of hurting people, which puts her at odds with a lot of what the school expects of her. She's got real doubts about whether she even belongs there or if the whole mission thing is right for her.
She's best known among fans for being the first person to encounter Mimi, which honestly unsettled her more than most encounters would. What got to her most wasn't Mimi herself—it was how cheerful Mimi seemed while literally covered in blood from the fighting. That kind of cognitive dissonance stuck with her.
Things shift when she and Mimi end up assigned as roommates. Living together forces her to actually get to know Mimi beyond that initial weird first impression, and a lot of her understanding of the other girl changes from there.
