An 18-year-old high school senior, Miou is the club president of the Aogiri High School Survival Game Club. She came from a rich family and her beauty and charisma made her well respected in school. She seems to lack common sense and is quite forgetful. She was held back a year in high school because of misconduct, and thus the only club member old enough to apply for a license for the model guns the other members are too young to use.
