The Devil Butler is about a guy who used to be the Demon King. He gets betrayed and murdered, so that part of his career is over pretty fast. Then he comes back not in a mighty, fearsome body as you might expect, but as a lowly servant bound by a contract named Fan. It's a rough gig, especially since he's tied to Lady Luo and can't exactly walk away from his new duties. Most of the story is just him trying to claw his way back to power while dealing with all the mundane and not-so-mundane baggage of his new life. You can sense the danger lurking beneath his subservient exterior, but he's no longer in the position of absolute authority he once held. It's a reincarnation fantasy manhwa with a slow burn revenge flavor pretty straightforward and enjoyable for what it is.
