D.E.D. Exorcists, an Augmented Reality game taking the world by storm, had playerse taking on the role of 'Exorcists' to protect the world from Digitally Energized Demons (D.E.D.) who threatend their world. It was a popular game, with millions, tens of millions, taking part within the first week of its release.

However, it wasn't just a game. It was a front, to search out candidates to enroll in the weakening ranks of the Exorcists, to stand against the very real demonic forces coming from a different dimmension to feed on Earth's people, and, its matter. 

Henry, having downloaded the game just to see what all the hype was aobut, is quickly thrown into a world he never knew existed. He apparnetly has a potential to become one of the strongests Exorcists around. However, he's got to survive long enough to do so, and he learns things around him aren't as they seem. Not only that, time, it would appear, is not on his side. 

The D.E.D. are increasing their invasion attempts, the Exorcists are growing weaker, and other threats seem to lurk around every corner. What started out as just a game for Henry, now, becomes a race against time, and a battle with not only his life on the line, but that of the whole world.
