During PE class, Aoki notices Mimi's large chest. He starts thinking of a way to deal with it, and in the process, makes Hoin think that he's a lolicon. Later, Mimi goes shopping for a bra, but does not know anything about them, and ends up buying a bra that didn't fit her. Two boys at school make fun of her, so Rin and Kuro help Mimi purchase a bra by taking her measurements at Kuro's private clothing department. (Source: Wikipedia)
