Akira Fudo, a shy and reserved teenager, goes on a mountain-climbing trip to the Himalayas with his father. Both die in a tragic accident. Afterwards, the demon soldier Devilman takes over Akira's body, using his human appearance to hide his true nature as he prepares to unleash destruction on Earth and pave the way for a demon invasion.
Before Devilman can execute his plans, he runs into Miki Makimura, his childhood friend, and quickly falls for her. Deciding to protect Miki and humanity, he turns against his fellow demons. Zennon, the leader of the Demon Tribe, becomes furious at Devilman's betrayal and dispatches his former allies to kill him. Once the other demons discover how much Miki matters to Devilman, he must defend both her and himself. Can love triumph over evil?
