On some sites which have ads I've been seeing the following image
possibly NSFW if you look hard enough
Now I've only seen up to episode 130 and I've never seen her before. However she kind of looks like Lighting (AKA Clare Farron) from Final Fantasy XIII.
I am wondering: is this girl really from Bleach? If so when would I see her in the series (which episode or chapter), and if not where is she from?
