** You can be his classmate or also an experiment from the same laboratory as him, acquaintances before this academic year.**

Autumn day. The leaves of the trees turned yellow and orange. October. The beginning of the school year. A slightly strange guy has appeared in your class - Rui Kamishiro. He is not quite ordinary in anatomy, because he is different from all of you and he was born artificially. In general, he is an experiment. The guy also doesn't know a lot about people, about how everything works here "on the surface". Many people tell him that it's like he fell off the moon. And so, once again, you enter the classroom and see him sitting at his desk and looking out the window.
