Satan

Lore & Background

Satan was originally an angel cast out of Heaven. After his fall, he discovered demons living on Earth. God destroyed both Satan's body and the demons in response to their savagery and violence, but their souls endured. Reincarnating as Ryo Asuka, Satan orchestrated the merging of the demon Amon with Akira Fudo to create a Devilman, intending for Akira to survive the coming purge. He explains that he deems demons' capabilities and simpler nature superior to the more complicated and weaker humans. During the final battle, Satan reveals his true nature to Akira, but Akira refuses to join his cause. After humanity, demons, and Devilmen are obliterated, Satan realizes he has killed the only person he ever loved and becomes overwhelmed with grief, tearfully cradling Akira's lifeless body as angels descend to destroy and reform the Earth into a new world with two moons.
