I am kind of surprised that SMT has never had a stink raised about it - like, I know it is niche, but it isn't that niche. I mean, it really throws a bunch of religions, mythologies, and folklore together - with little descrimination for what is or is not believed in. Persona 5 is really all over the place with its main story's mythological persona - we have some Greek, some Chinese, some Syrian, some Japanese, some Gnostic, some Roman, some Norse, etc. - but its compartively-mild to mainline SMT wherein so many different traditions can appear fighting on the same side of a singular war.
As a mythology nerd, I love the repurposing of mythologies this series does, but I don't imagine everyone would appreciate it.
