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. With no way to finance his prestigious education, William decides to search through his uncle's mansion for something of value to sell. But William's logical worldview is about to take a hit, when 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. Such news might drive a lesser man mad, but not William Twining. He's 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. None of this can possibly be real, can it? Besides, he's got bills to pay.
