An anime where a girl with pink hair, half naked (or completely naked), with supernatural power making limbs explode in the first episode In the first episode, a girl with pink hair, half naked (or completely naked), with supernatural power makes limbs explode. In the first episode or the second one, she's embraced (?) by someone. If I remember correctly, she's mentally like a child, or really lacks communication abilities.

Any help would be much appreciated! 

P.S. Sorry for the terrible description, it's just that I have vague memory about it.
I think you are talking about Elfen Lied. It's really crazy, especially the first episode.
