[Don't come close, the life of gods is more chaotic than that of mortals]
Since the character relationships are too complicated (I have no choice but to do so at the strong request of some fujoshi~), in order to prevent readers from wanting to find me, the author who created such an "evil" thing, and give me a slap in the face, I will first sort out the general character relationships for you (of course, I will not go into details here for the kind of beautiful characters who pass by in a flash, I hope you understand~)
The levels of heaven are roughly divided into five levels
