To be fair anime is a HUGE market in Japan etc, some 'men' even prefer anime women over REAL women (yeah I don't get that either).
This anime character isn't really aimed at the western market even though there are people (like myself) that enjoy anime.
I will say that I have seen worse anime characters and you should be thinking yourself lucky MS took this route and not the 'big boobs falling out of every top' look....
Now the 'firefox' character is kind of cheating because anime has a history of mixing a wolf (as in crossy's picture - thats Holo from Spice and Wolf), fox, cat (nekomimi - cat girls) or dog with female characters...
