After ending up in a traffic accident on his way home from school, Kei Nagai discovers he is an Ajin (demi-human). Ever since, he has been chased by both police and the Ajin Management Committee. Whilst Kei is on the run, he is approached by Satou, a terrorist Ajin. In order to teach Kei a lesson, Satou hands him over to the Ajin Management Committee. However, his scheme ended in failure. Satou parts ways with Kei, and begins a large-scale terrorist attack on Grant Pharmaceuticals alongside other Ajin he recruited.

Now, in the present day, the fight between Ajin terrorist Satou and the Ajin Management Committee takes a new turn.

“The Second Wave will be purification.”
