(The 2nd Season of Ajin.) It all started 17 years ago in Africa. The American army was the first to catch an immortal also referred to as a 'Solider of God.' In that moment, the existence of an “Ajin” was confirmed. No matter in what manner they were killed, disease, accident, etc. their bodies regenerate immediately in perfect health. This is the dream of humanity; full of endless possibilities. From that incident, 46 have been discovered worldwide and two are in Japan. However, they are rare in form, and it’s even harder to know what they are made of. So the theory held is “until we kill them multiple times, we don’t know enough about them.” Due to this, it is believed that there are more in the world. One day while walking home after school, high school student Kei Nagai is killed. However, he is immediately revived and completely unharmed. This would make Kei the 3rd Ajin to have been discovered in Japan. Kei now has to avoid the Ajin Management Bureau as they come after him. To further complicate things, there is now a bounty on his head. He gets help from his childhood friend Kaito and runs away to the mountains to hide. However, the police have deployed emergency forces to try and find him and they are closing in. Kei hatches a plot to run away again. One of the two Ajin in Japan named Takana but nicknamed 'cap' had escaped from confinement and begins to implement a series of terror attacks. Tosaki, the head of The Ajin Management Bureau now has to find Kei and stop these terror attacks. He also has his eye on Kei’s younger sister, Eriko Nagai. However, to top things off, there is another Ajin who has sworn revenge on humanity and a strange black creature called IBM on the loose.
