My anime obsessed friend is driving me crazy!?

I have a friend and all she talks about is anime! Anime this, anime that...it is driving me nuts!!!! She always talks to me about it and I told her that I don't really care about it and she still talks about. She knows that I don't like animes but still won't stop talking about it!!! Whenever we are on the phone all I here in the background is Naruto! She is even trying to learn how to speak Japanese! I don't think that she will get anywhere just by listening to the theme song. OMG and one time she was even talking about getting a face transplan because she wants to look japanese but her mom thought that was weird. She has totally changed since she started watching animes. Her attitude has become more mean. I honestly have nothing against animes, but I have been putting up with this for too long. I try to talk to her about this but she just ignores me. I have been in other situations with her where I thought she had turned mean and when I try to tell her she just denys it. I really want our friendship to be back to the way it was. She is not even a little Japanese. Her profile thing on yahoo answers is "I love animes" and her description is something like "Anime is my life." Also, on her youtube thing her intrest is "Animes...only animes." Her about me thing on youtube has this decorative thing that says "I love animes." And it also says how she is obsessed with animes. She knows that she is obsessed with them, but she doesn't care. Like I said before, I want our friendship back to normal! What should I do! BTW she is really sensitive. If I try to save our friendship I might ruin it!
