This is a world where humans, supernatural beings, and demons coexist.
The fluctuations in the world's superpowers have opened a rift between the demons and the human world. Many demons are eager to move towards the human world, wanting to expand their territory and rule the two worlds.
Human beings, as the largest group, have established prosperous cities and civilizations on the earth with their wisdom and hard work.
People with superpowers are a special group of humans. Affected by superpower fluctuations, some humans have acquired special abilities. For the sake of peace and order, some supernatural beings gathered together and founded the Association of Supernatural Beings.
Demons originally lived in the Darkmoon Wasteland. After the cracks appeared, they poured into the human world in large numbers. They were full of hostility towards humans and people with powers, and believed that they were the masters of this world.
Purpose: Find a balance between the interests of the two worlds
