This is the realm of Xiutu where humans live. It is a doorway connecting to other continents. There are existences other than humans, including monsters, strange beasts, insect-eating insects and Aweizi. Demons lurk in the human world, taking human form and making a living by eating human internal organs. Human beings are helpless against the demons and can only turn to the magical organization Aweiz.
