Shiranui Is beautiful. Many people tell stories of her but here is a short one I heard from the game: Shiranui is Amaterasu 100 years ago. Her markings are not seen to normal people, but to other gods much like her can see her markings clearly. Amaterasu transforms into Shiranui at the very end. when you finish the game 1 or 2 times, you get her markings.
