Japanese mythology fanfiction? No, there are plans to include other mythologies like Chinese as well. If you hadn't realized, the first city in chapter 7 was Hong Kong.
I gave readers enough information to understand the story. There are times when I didn't include certain information because Adam doesn't know the answer. The story is written in third-person limited.
Also, I am not sure why you would want to read infodumps, but hey, you do you.
