DevilMan Japan

Devilman is a Japanese manga series written and illustrated by Go Nagai which originally started as an anime adaptation of the concept of Nagai's previous manga series, Demon Lord Dante. A 39 episode anime series was developed by Toei in 1972 and Nagai began Devilman as a manga in Kodansha's Weekly Shonen Magazine, barely a month before the anime series started. The series has since spawned numerous OVAs, manga, novels, and films.
