Might as well complete the quartet. Check out BASTARD!! It's way less serious than the others, but chock full of violence, over-the-top action, and meticulous art.
Also, while I haven't read it yet, one of Berserk's major inspirations was Devilman, which apparently influenced its explicit content, apocalyptic stakes, and epic character tragedy.
