You keep saying this but what do Magic Gods have to do with it?Yeah, you are suffering some absolute brain rot to suddenly go "That's not the Great Will because there would be no conflict" when there is nothing at all stating The Great Will causes conflict. YHVH is just it's extension and it's explicitly stated by Atlus that a massive fucking in Reality caused Him to go even harder than his Old Testament self.
Secondly, you just proved the point right there so how the hell does To Aru benefit from shit in the Phase? Which is not connected to the Universe in the fashion you are coming up with.
Yes and thus, why would anyone scale from them in the first place? Especially when the Magic Gods exist?
They're former humans, and most of them literally based their ascensions off of the already existing myths.
