This show is very good. Ray was shown as a kind girl at first as she wanted to help the bird. But, after i knew what she did to her parents and the way she kills anyone who enters that room.. my thoughts changed about her. But, she is still the best and nothing was her fault. And about Zack? I think he is the most innocent character in the movie. And his parents deserved everything that they got as a revenge and Zack got a reason for being a killer. And also, Isaac Foster is 20 and Rachel Gardner is 13. So it's not possible to ship them right now. But when she becomes 18 and Zack will be 25, i will ship them a lot. Zack is very strong.. nothing could kill him- but on the other hand, Ray in very intelligent. They belong to each other. I rate it 4 stars because.. i think Zack actually killed as he promised at the end. I am not sure.. but by his words i can say.. Well, other than that, i love this anime but it gets boring and very in interesting at the same time.
