Devilman Grimoire Vol. 3 (manga)

The time of demonkind’s full revival draws ever closer, as more and more humans succumb to possession. Against them stands only the traitor Amon, in the body of human Fudo Akira. His deeds have not gone unnoticed. Lord Atrocious, the Monster Shogun–strongest of demonkind–demands Amon’s head! The strongest demons from across the world descend upon Japan, seeking Akira’s life, even Lord Satan himself! It’s one demon against the world–but Amon won’t hesitate to kill anyone who stands in his way.
