wow good explanation masa!!
yeah I think I'm also a Shintou based person and I believe in the 3 characteristics of Shintou, however I'm also a Hindu and the main characteristics are similair to Shintou - I would say that Shintou and Hinduism are kinda similar - "There are many many gods in nature", "To wish good harvest and prosperity", and "To value purity very much". I believe in many gods and in prosperity and purity.
I also think that Ayu may believe in Shintou
