Bullet Witch

First, there was the earthquake. Then the war, then the plague, then the riots. In the span of a few short years, humanity suffered every disaster imaginable — and all as a prelude to the one we couldn't have imagined. An army of literal demons marched straight out of Hell, trampling over the survivors wherever they found them. When they killed, they wore their victims' skins. When they conquered, they seized their enemies' weapons. Powered by supernatural evil and loaded with military hardware, they scattered us and ran us down.
