Fumio Daimido is the caretaker and dorm matron of Polar Star Dormitory. She cares greatly for the students that live in her dormitory. Though she is quite benevolent and patient, she is exasperated by the mayhem that the residents cause, such as Yuki Yoshino's wild animals running loose inside the dorm and Shun Ibusaki's smoke cooking. She holds great pride over the Golden Era of Polar Star, which made the dormitory into the self-sustaining dorm as it is today. Fumio values true tenacity and hidden potential. Needless to say, anyone that lives in Polar Star has great skill and boundless potential.
