Anna is a teen model who is a good friend and classmate of Maiko; she is similarly well-known and experienced in modeling. From early on, Anna makes it clear that she disapproves of Shūichi dressing as a girl, and even calls him a freak. Anna initially tells Maho she has no interest in her "weak" brother because of his femininity, though later dates Shūichi for a time after he asks her out. Furthermore, Anna's opinion of Shūichi's cross-dressing also changes, she saying that it actually suits him, and the two even go out together on a date with Shūichi dressed as a girl. She feels Shūichi is an interesting person, and once says he is like a cute little sister. Anna spends a lot of money on clothes, and enjoys modifying them.
