In an apocalyptic world taken by demons, one man is the only hope to save what's left of these ruins. Isaac Williams, the last Demon Hunter, must accompany the demon, Sarkany, on a journey to defeat the demonic ruler, Abaddon.
Demons live on earth. They are segregated and treated poorly, as if they were inferior. Hunting them has become a sport, capturing them, a game. The largest Hunter in the world has been killed by one of his own prisoners and one demon has been captured by the devil himself. Now, a journey into hell and back will decide the fate of the world, and possibly existence itself.
