白川 紅

Hime's roommate and the only other human attending the Trinity School. Kou is a skilled swordswoman and wielder of speed-enhancement and wind magic that allows her to compete with the best of the other races on equal terms. She is very close to Hime, with whom she has partnered since her entry into the school due to their fundamental lack of allies in the current student body. She is cool-headed and ambitious in the sense that she has a strong desire to fulfill her dream of graduating (a feat no human has managed so far). Like Hime, she has adopted an attitude of nonchalant resignation when it comes to the prejudice they suffer from the other races.
