Yaya

Yaya is Raishin's puppet who takes the form of a raven-haired teenage girl. She is abnormal in the sense that her appearance and personality strongly resemble that of a human. She adores Raishin and often teases him.

Yaya was named for her indestructibility. She is a Banned doll, meaning she is a puppet who has human components. She has real human blood and skin.
