Chihaya is haunted by strange visions of black wings. Do they hold a special secret, or is it a disease that is prepared to claim his angelic life? Chihaya's search leads him to Sapphire, a black winged, fallen angel. Un- fortunately, Sapphire has become a rock star who lives in hiding and is tormented by a lethal drug habit.

The Great War between the Angels and the Earthians is over, but Dr. Ashino still lives. While Chihaya and Kagetsuya, are in the midst of rescuing two young angels from the doctor's horrific laboratory, they stumble upon Messiah. Messiah, a genetically engineered destroyer in the form of a beautiful young angel, only has eyes for sweet Chihaya.

Messiah is missing, and presumed dead. Chihaya, however, is convinced the angelic destroyer is very much alive, and his obsession with finding Messiah is endangering his relationship with Kagetsuya. Now Chihaya will not only lose Messiah to the mad Dr. Ashino, but he may lose his own life to the very one whom he cares most about.
