An anime directed by Mamoru Kanbe.
Some mutant girls are born with horns, invisible arms and an insatiable desire to extinguish human life. A young boy makes friends with them.
When I looked up "anime with nudity", this is what came up. I thought it was alright. The plot was all jumbled up with tons of flashbacks and the characters were one dimensional. There was some nudity and lots of violence, including the typical Japanese style of spraying blood. I rate it adequate.
By the way, I'm going to be posting here again due to the amount of stuff that I watch and how much of it is available on youtube. I will not be providing links because of how transient and temporary the posted videos are on that site.
