Suzuno Himura
Her family's business has failed making her family poor, and to lessen the burden on her parents she leaves her expense private all girls school to the extremely cheap co-ed dorm for students with financial problems. Though that specific dorm is full of delinquent or "naughty" boys. Making her job as dorm manger and task of bringing order that much harder. Suzuno has a unique and/or unnatural ability; originally bringing nothing good, but now it's the only thing she has to defend/protect herself in this "City of crime" dorm.
