What About Mimi?: Sincerity Travers

A snobbish preppy teenybopper with pink hair who, sometimes, does not get along with Mimi. She and Mimi used to be friends years ago, but as they got older, their interests diverged, and they started growing apart. She is Mimi's rival in school, and although she does not get along with her, she admits that her ideas are pretty good and helps with some of her schemes. Even if she does not get along with Mimi, she has a resentful respect for her, showing that deep inside, Sincerity still considers her a true friend.
