Noriko

Noriko, Spirit of Tokyo of The Amatsukami.
Onetime member of Study Group.
First appeared in Season 2.
Noriko was murdered by Pecos Bill when he rode on Clearwater.
Riku Murakami and Fionn Corvin brought her ashes to Tokyo to lay to rest but discovered she was a spirit. She asked to help recreate her perfect day so Fionn went around Tokyo with her to an ice cream shop, a dress shop, ending at a small city playground she had loved as a child. 
There, she took the form of The Spirit of Tokyo, a goddess of light that protects the city.
