She spent five years as a Shinto priestess.
Let's break that down.
Kami are... Kinda but not totally spirits/gods?
Seriously, @neilhimself is a genius just for making a culturally understandable translation of Princess Mononoke.
Shinto involves countless kami... and you may pray or appease them EVEN IF YOU DON'T KNOW THEY'RE NAME.
Be some spirits are nameless.
They're not D & D gods.
EVERYTHING could have a spirit.
Or talking cell phones and appliances she retires.
She's thanking the object kami in a very traditional way.
I just enjoy it when bizarre geeky knowledge gives insight into popular things.
It's neat to find the wonder and the weird in the otherwise ordinary.
Episode 1, only fifteen minutes in, and she's already kneeling on the ground, leading group supplications to the house.
Glad to see they kept the Shinto on the screen.
