There are three realms in the world: humans, gods, and demons. The human realm is the foundation of the three realms. If the human realm collapses, the gods and demons will also be implicated. Therefore, the human realm is the best weapon to contain the two realms.
The God King and the Demon King are not the most powerful existences. There is an organization that transcends the three realms in the world, and that is - "Tianyi"! Tianyi is composed of four mysterious creatures. Some say they are exactly the same as humans, while others say they are monsters created by the Creator. In short, whether they are humans or demons, they control the fate of the world, and their mission given by the creator is to protect the three realms!
And what kind of stories do the four of them have?
Let's wait and see~~!
