Yaomo Gui is a victim of circumstances. He grew up and was born in the wilderness of Hunan Province, in one of the small villages. It would seem that life was calm and nothing foreshadowed trouble. However, one night, the village was attacked by demons. A young boy stood over the corpses of his parents, in a trance of pain. The run was futile. He was caught, taken to the wilderness and turned into a demon. Since then, Yaomo has been serving as a herald of death, taking the life of every person.
