One of Maki's shyer friends, who goes to a presumably rich, private school. Mina has ridiculously exaggerated, large breasts, normally used as a source of humor rather than fan service, and she is extremely self conscious about it. In addition to this, Mina is hopelessly in love with Maki, who is not sure how to handle the matter, making this the main reason her friends make fun of her. However, like Maki, she has her share of admirers as well; including Reiishi Mishima and many members of Kinjirou's Black Suit gang. She has been a fan of Nanjou Remon's novels since she was a kid.
