The Evil God Descends

He inexplicably became a vampire, then accidentally transmigrated to another world, where he ran into a horde of rats and was attacked by a giant rodent with his backside in danger. He passed out, but the villagers mistook him for a legendary summoner, and he became a supreme con artist who made the whole continent dance to his tune. A loser from Earth, he rose to fame in another world as the Gold Coin Reaper. Don't show off your wealth in front of him. They call him the Evil Duke, so don't bully him, or you'll wish you were dead. They call him the Noble Butcher, so don't assume your high status will keep him from coming after you! They call him the greatest con artist in history, and he'll blush and say, “I'm just a humble little vampire.”
