Shinyuuchi are mystical realms that exist within other dimensions from the real world. They cannot be seen by normal humans, but neither by those with special abilities, unless with the aid of special means. Shinyuuchi are realms that affect the balance of nature within limited areas in the real world by affecting the enviroment. Shinyuuchi cannot be seen within the real world, but can be accessed through shrines or mystical objects that can be used as portals from the real world, or they can be accessed by gaining the approval of a shinyuuchi's guardian deity,or its god. Since shinyuuchi are linked to the lands of the real world, they can also cause trouble for it. For example, should the power of the shinyuuchi weaken over time, the effects of it could weaken the enviroments within the real world.
