Haha this has to be one of the most unusual anime i have seen. So, this anime is basically about this high schooler, Shinichi Izumi who randomly is gifted with this parasyte named Migi. These parasytes invade and survive on the human host, come to earth causing a war between humans and parasytes. I really loved this one because of the characterization, likability of the chracters and the weirdness of the whole anime. It is very good and i hope there is a second season.
