15-year-old Chiaki lives on her own. She picks up a wounded guy, Ororon, who turns out to be a demon king. They fall in love, and he tries to protect her from monsters who want to eat her and angels who want to kill her because she is half-angel and half-human (her father was the archangel Michel).

Serialized in Wings.
