From Tokyopop: Lonely, but affectionate 15-year-old Chiaki, half-sided daughter of Archangel Mikhail and a human woman, takes in his house a sad devil Ororon, who undertakes to stay next to him forever. Both were excluded from their heavenly kingdoms: Chiaki, because his origin is unclean, and the Eagle, because he is the younger son of Lord Devol and, therefore, the threat to his senior brothers by the leadership of the underworld. While several celestial agents arrive to destroy the Angel Chiaki, it discovers that an incredibly powerful eraft is useful. And as a killer for a killer comes to eliminate Ororon, he discovers that Chiaki can teach him a valuable lesson about holiness of life.
