Devilman/Devilman Grimoire

Devilman (Japanese: デビルマン, Hepburn: Debiruman) is a Japanese manga series written and illustrated by Go Nagai. The manga focuses on a high school student named Akira Fudo who absorbs the powers of the demon called "Amon" with help of his friend Ryo Asuka in order to battle creatures hidden in human society, thus calling himself the "Devilman" in the process. The series was originally ordered by Toei Animation as a toned-down anime version of Nagai's previous manga series, Demon Lord Dante. However, Nagai wrote a darker-toned manga in order to alert readers of the dangers of the wars based on how dark the narrative becomes with each of Akira's challenges. Devilman G デビルマンG (グリモワール) (also known as Devilman Grimoire) is a manga written and drawn by Takato Rui for the 40th anniversary of Devilman to introduce younger generations to the franchise with a completely fresh tale from the original format.
