Description: In the center of the cosmos of Russ, a tower exists. The name of that tower is 'PRISON OF SON'. In this tower, the sons of man are sentenced to be imprisoned forever. The reason why they are sent there, no one knows, but one thing is for sure: you can escape, and bring an end to the eternal loop of false judgement that has fallen upon you. You are one of the prisoners, you don't know for what reason you are here. The only thing you know is that you want to escape and learn the truth. You must escape. You must do it because if you don't, then who will save you from the eternal doom?
