William Twining has it all - a sharp intelligence, dashing good looks, and a noble station in life. There's only one problem: he's broke. Searching through his uncle's mansion for something of value to sell, he comes across a mystical seal which he unintentionally uses to summon a demon. The demon's name is Dantalion, a Grand Duke of Hell, who informs the young nobleman of his destiny - that he is the new "Elector" whose sole responsibility is to appoint the next ruler of Hell in place of Lucifer. But William Twining is a realist whose views don't allow for the existence of demons, even when scores of demonic candidates begin to knock down his door and seek his favor.
