For Kouta and Yuka, finding the bloody naked young girl on the beach would change their lives forever, for better or for worse. Unable to speak or function as a normal human being, she is named Nyu by the duo, and taken into their home in an effort to save her. But what neither teenager knows is that this innocent young girl is actually a killing machine -- an experiment gone terribly wrong -- and it is only a matter of time before the murderer in her awakens again...

Another show with an interesting concept. 2 youngsters that find a girl with red hair and horns on a beach, who has a split personality and a hidden mutation. One acts like a little kid that is trying to forget what she’s done in the past and the other side has become a killer due to other events that have happened in the past.

A military group tries to recapture the escaped girl with the help of girls with similar mutations as the escaped girl.

The main story development is pretty good and everything flows at a good pace. Although a lot of the characters have moments where they legit seem dumb. The characters themselves are pretty weak, the relationships between the characters are kind of awkward too.

The voices can be annoying at times, whispering doesn’t make a character innocent. Art-wise, it’s all pretty solid but I just can’t get behind the giant kid eyes. It feels out of place.

Some of the shock elements aren’t really needed. Other then that, the violence is done in a pretty effective way. I’m not a fan of replacing the chopped off limbs and bringing back characters that died.

So the story is alright, characters are pretty weak, the violence is pretty effective and there is some silly stuff that happens along the way that’s just not really needed. The strangest thing of all is how everybody thinks it’s okay to keep it in the family.
