I really don't know what really happend because they have switched everytime and I could not understand whats happening right now. First they showed us the class and then in the other episode there were just a girl and a boy. I also hated the reasons why they killed her, but it made the anime scarier. I wish she would take revenge from the class, but they did not show them. Also I think this anime is similiar to the Thai drama called "Girl from Nowhere", but the only difference is that "Girl from nowhere" made sense but this anime made no sense for me.Also the characters looked really ugly, also the art, but you know that its an old anime so I did not care. I think this would be so much better if the anime were longer but you just stopped in the most exciting scene and in the other episode it was about someone else.
