One of the Tamamo Nine. After Tamamo-no-Mae raised her divinity through thousand-year training, she returned to a one-tailed fox and the other eight tails were cut off.  Each tail gained divinity of their own and became individual souls that could be summoned as Heroic Spirits. A crystallization of the (rather) pure side of Tamamo-no-Mae.

What we’re looking for: A cat-like quality to the way she speaks. 

Vocal Reference: Black Hanekawa from the Monogatari series. Here’s a link to her voice lines in the game as well.
