Ninja girls horns are actually visually closer to a horned chameleon than a goat. Add in that her ponytail curls at the end like a chameleon tail and her skin is legitimately black with lighter spots (Chish took a screenshot and increased the brightness and saturation), and it all seems to be pointing at ninja girl being a chameleon Faunus.

I had the thought that maybe she was supposed to get caught, or at least spotted, and lead a pursuing Blake to a waiting Adam.
