The main antagonist is the god of the Simon Empire, Orobas. Orobas is essentially the devil in disguise and is trying to take over this world. The general lore of the story is that there are multiple worlds which are delegated to angels by the main God, and sometimes devils try to take over a world that is handed over to an inexperienced angel, like the world in the story that takes place.

the fact that multiple wishes were made and granted by God with heavy sacrifices, but all of those prices were sort of reversed. I wasn't expecting a particularly dark novel where there is an enormous price that one has to pay. I expected to some extent that the ending was going to be happy. In fact, I was hoping for a happy ending however, overall the author gets into a tendency of having characters pay a heavy price for a particular wish being granted by God and then, having that price, somehow, in some shape or formed reversed. It's sort of feels unfair that those around Cassia and Zester constantly have their wishes granted, but not anyone else. It's not surprising considering that the main God, Ra, is loves Zester and has come down to the human realm as Cassia without memories (doing this every life Zester is reborn). The novel doesn't really get into the philosophical nature of a God favoring certain existences over other existences. As Zester and Kasia's wishes are constantly granted. You wonder in the background, if you're like me at least, what about the other children who lost their mother? What about the other mother who lost their child? What about the other husbands and wives who had strange relationships because of weird misunderstandings in the beginning of the relationship. Essentially, you wonder these things because the author isn't committed to making his character or readers feel any cost to their actions.
