She has a pony tail, too... Hmm not so sure about that for Rukia's look. Seems like they tried to go for a more realistic interpretation, instead of making it look just like the anime. Problem is, if you try to make it look just like the anime, it looks really weird sometimes, even the animes with more "normal" and "subdued" hairstyles and looks.
It's a no-win scenario, really.
