Each of her tails is left a portion of her divinity and becomes a Heroic Spirit. She is the crystallization of Tamamo's more pure and sincere aspects, as well as the more feral parts of Tamamo's nature. She is something like a wild cat that one cannot tell what it wants to do, nor what sort of mess it will make.

I am Archer of Inferno.

I am a teenage girl with purple hair that is tied in a side-ponytail which is held by a shuriken-like hair decoration of the left side and green eyes.

This serious side can also make me straight forward and stubborn to the point of not always admitting how I'm truly feeling.
