Recently, I always feel that something strange has happened around me, and I am always very uneasy and have a very bad premonition.Although it is still sparse and ordinary on the surface, I always feel that there is a malice in the undercurrent.Ah, forgot to introduce myself.I am Yuki Rito, a slightly ordinary boy who studied at Cainan University.If there is something different from others, it is probably because of the earthlings, but I know a lot of aliens.
