William Twining has it all - a sharp intelligence, dashing good looks, and a noble station in life. With no way to finance his prestigious education, William decides to search through his uncle's mansion for something of value to sell. But when William comes across a mystical seal, 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. None of this can possibly be real - can it? - and besides, he's got bills to pay.
