Maria Kawai transfers from St. Katria Girls' School to Touzuka Public High School, and her arrival sparks interest for two reasons: St. Katria has an excellent academic reputation compared to Touzuka, and Maria is incredibly cute! When her classmates speculate upon her transfer to their less-than-impressive school, she flatly informs them that she was expelled for violence against her former teacher. This is characteristic of Maria—despite her angelic appearance, she will tell the unadorned truth regardless of social niceties, and as such, people often compare her to a devil.
