Tamamo no Mae

Tama is a Nine-Tailed Fox in the form of a small blonde girl with curls in the back of her hair and is also one of the three most powerful Ayakashi in Japan. Despite her cute and childish appearance, she is very powerful, though not nearly as powerful as she was before. To regain her power, she eats other Ayakashi, once devouring an entire countryside of them in her debut appearance. She has her eyes set on Himari, but when she first tastes her, she states that she wasn't delicious because she was holding back her true nature. She is displayed as a quiet girl, rarely talking and is always seen eating something, be it a demon or some sweets. In the anime, she is defeated by Himari's demon form but survives. Tama is last seen in Yuto's house eating lunch with the other girls. (Source: Wikipedia)
