Demons, once trapped in the glacial ice of the Earth, have been unleashed on mankind after centuries of non-intervention. Only two men have the ability to stop them, the cool-headed Ryo, and the fearless Akira who, as Devilman, possesses the body and strength of a demon but with the heart and soul of a human. In Demon Bird, Akira is confronted by more deadly horror as obscene and twisted creatures struggle to take control of the world. Miki, his girlfriend, is brutally attacked by the fiendish water-demon Gelmar whilst Devilman takes on Jinmen, who carries the tortured souls of his victims embedded in his gruesome shell. But the combination of human and demon makes Akira a formidable force-- until he meets the vicious talons of Siren, the invincible Demon Bird!
