This anime is very sinister. It is not clear why the main character was left behind with the mark. After the attack on his class and him the only one left he is put into a confinement center. No trail or anything he just has to be guilty.
While in confinement strange things happen that is really confusing. This review may not be accurate and forgive me, but while watching this I did not comprehend everything that was happening. The boy was scared because he was in a place he shouldn't be for he was not guilty.
In confinement there are different type of torturing he indure each one worse than the last and none of it makes any sense because he shouldn't have to go through this and no one helps him.
