Internet Demon

In Hell, there is this devil. This devils who is strong enough to rival the Satans. He arrived at the year 2007, and from there, he became collecting deals from poor devils who can't pay him back. And one of those devils, is Rias Gremory, who will have to pay getting of her wedding with Riser, and sadly... she can't follow her end of the deal. How amusing. Alastor Like Issei
