Kei Nagai is a good student whose life turned upside down when he was struck by a truck. After this accident he discovers that he is an immortal (ajin). Feeling shocked and panic, he runs away to an isolated place. Now he can't trust anyone but his childhood friend Kaito.

Tosaki takes the pursuit of government by Ajin. Kei and Kaito are attacked by bandits in search of rewards.

Izumi fight against a being in Eriko's hospital room. After saying goodbye to Kaito, Kei receives a mysterious invitation.

With his job at stake, Tozaki takes drastic measures to find out more about Ajin. Sato takes his emphasis on putting into practice a new plan.

Tozaki make new discoveries. Neighbors Mrs. Yamanaka suspect Kei. Sato finalizes his plan.

Mr Keita reports Kei Nagai to the police to claim a reward. Yu Tosaki orders all available forces to the area to catch Kei. When Kei is confronted by the police, he uses his Black Ghost to delay them allowing him to escape into the woods. He uses Ko Nakano’s phone to throw the police off his trail, but Tosaki realizes it's a ruse and closes in.

Sato is able to assassinate another off of the list. Nagai and Tosaki begin planning their counterattack against Sato. Nagai begins to struggle with the behavior of his IBM, wondering if he himself has to change. Tosaki also let's Nagai know Kaito's current condition.

Tosaki has been captured. Izumi rushes back to the hideout and insists they rescue him. Initially refusing, Nagai ultimately leads a team to rescue Tosaki from the Americans.

Tosaki manages to get his team allowed into the building where Sato's next target is. Just as the clock ticks closer, a truck rushes in and sets off an E.M.P. bomb, rendering all electronics and new anti-Ajin guns useless. Sato charges in for an old fashioned gun fight.
