VS Demon King

He's the Demon King, the worst being to have ever placed foot in existence, has made the worst of worst, he's a force of nature that one can't reason with, and only sees humans and other races as ants, not even searching them for pleasure, just to destroy them, not even that bringing him satisfaction. He's a Force of Nature which one can't reason with. Try to defend your planet... Or perish with the rest.
