First thing, this anime is NOT FOR KIDS. I watched one episode and it does have a lot of gore and nudity,the animation is really good also. I havn' t seen much of it yet but it' s next on my list of things to buy (next to Geist).

What I know so far about the story is a girl who was being experimented on breaks free and escapes the facility. Upon doing that she kills many innocent people but when she' s almost out of harm, a sniper shoots her in the head (she had some type of helmet on though) and the helmet breaks knocking her into water. Then two people find her on the beach and all she can say is her name Nyu because she lost her memory. The two people (Brother and Sister) take her in.

I will tell more when I buy the DVD' s. Right now I think there is only vol. 1, the show is only 13 episodes also.
