Anastasia

Saizo's childhood friend and as well one of the Sanada's 10 warriors.

A beautiful Russian girl and female member of the Iga ninja, she uses ice magic and is capable of freezing water and mist in an instant, thus earning her the name "Anastasia the Frozen Flower." She targeted Yukimura but was defeated, so she decided to join him. Both Saizo and Sasuke call her "Ana."

She is very playful and cunning in nature, but also becomes serious when the moment calls for it.
