A boy was born different. He did not belong to this world. The fortune teller said that he was not a human being at all, but a non-existent person. He was an illusion. However, he could always feel what others could not feel and see what others could not see. Indeed, he does not belong to this world, but to another space. The story revolves around this different boy. The gap between the two worlds is quite large. He becomes the bridge connecting the two worlds, and a "war" is inevitable. And in that world, there is no time or even space. There are only mature things that people in this world may not be able to do in a few years. It is wonderful and thrilling. However, this was actually a conspiracy that had been planned for a long time.
