バイオレンスジャック
A month later after finishing "Devilman", Nagai would create a sequel to it called "Violence Jack" (ヴァイオレンス ジャック), another long-running series that spanned multiple volumes and dealt with a giant brute of a man fighting for justice in a post-apocalyptic setting where Japan has been devastated by a massive earthquake and isolated from the rest of the world.
