In a world where the lines between Earth and the Netherworld have been blurred, a horde of demons have broken through. Much of Earth lies in waste, most of society driven back to Old West levels of technology. Enter Gideon, and those like him. Weilding a pair of six shooters with runic engraved bullets, he roams the deserts of the American west on his modified motorcycle, trying his best to return Earth to those who belong here. One demon at a time.
