"Long time ago. Vampires were ruled over the world and used humans as slaves to feed their designer of human blood. Or children to make them an army. Only humans fight back by using demonic weapons to kill vampires and other monsters. It is up to you to stop the cold blood war. Or else nobody will stop the blood shed that spill the whole world."
