So I'm curious about this Tamamo's syncretism debacle, and I searched around.
Hoo boy, there's so much I don't even know where to start. There's a post in some forum explaining about her syncretism, and it involves many, many schools of thoughts with various cultures surrounding said religions, so it's complicated to explain for me. I'll just go and say some writers from Edo period got too creative on syncretizing her. Basically, there's actual basis behind her complicated background.
