Rukimedes Shodai

A millennium ago, this founding patriarch of the demon realm led a massive army of monsters in a sweeping invasion of the human world, only to be ultimately sealed away by the heroic warrior Creahion. As the root cause of all chaos within the story, the breaking of his seal directly sets the main narrative into motion. As the grandfather of the third-generation Demon King Ruky, he commands an immense reservoir of dark power and harbors an all-consuming ambition to dominate the world. While radiating an overwhelming villainous authority, he simultaneously embodies the signature absurdist comedy that defines this series.
