She lives in the mansion and attends Mihate High School. Maimi is strong-willed and doesn't like to give up. She gets high grades and is good at sports, being the top athlete in the tennis club after joining it two years ago. She is sloppy and tomboyish despite her looks. Kensuke calls her an "unfortunate woman" and "cute if she shuts up." She has a very low tolerance for alcohol, and gets drunk off the smallest amount from a piece of fancy chocolate candy. Because her birthday is August 31st (the last day of summer break), she has never had any friends celebrate her birthday, and she has always resented this fact.
