This article involves a variety of elements: BL, BG, gods and demons, etc.
The background of this article is set in multiple parallel spaces, that is, "one earth, multiple worlds." There is also an organization called the "Double Thirteen Society" that controls the entire world "secretly". (Limited to the third parallel world)
There is also a second parallel world that has not yet been announced.
Finally, I'm new here, please give me some advice. (Laugh)
