Ayu and Religion

[Chocho]

Isn't it like Japanese people aren't that strict on religions? Like Christians also go to Shinto temples to pray or the other way round. That's what I read somewhere.

I don't think she's a religious person. I haven't read an interview with her where she mentions her religion, or that she belives in a god.

Her crosses might be a fashion thing. And, as ImpactBreaker already mentioned, crosses aren't owned by the Christian Church. Just because you're wearing a cross or incorporating Christian things in your MVs or lyrics, doesn't mean you're Christian.
