Nagi Kirima

Known as the Fire Witch, Kirima has made few friends due the way she distances herself from others: she knows that she is too dangerous for "normal" people to associate with. She has a messianic complex, and seeks to save the world from whatever may threaten it. As such, whenever there are unusual happenings within the city, Kirima can be found investigating what has happened. In the past, she had spent a period of time in a hospital. A combination of the events from that period of her life, as well as the death of her father, the famous writer Kirima Seiichi, brought her to follow this path in life. Extremely gifted both physically and intellectually, she has the basic tools she needs to carry out her self-appointed mission.
