The three realms (demons, immortals, mortals, etc.) Do not interfere with each other. Only after death can you travel to another realm (this is the setting of Three Lives and Three Worlds). In order to prevent chaos, there will be an inn that specializes in managing the souls after death. But for unknown reasons, an organization called the Black Crow frequently causes chaos, causing chaos in the three realms.
