The Best Episodes Directed By Keisuke Ide

Ajin are humans that cannot die. Seventeen years ago, they first appeared on a battlefield in Africa. From then on, more of their kind are discovered within the human society. Their rarity in appearance means that, for experimental purposes, the government will generously reward anyone who captures one. In the present day, for what a certain high school student expects to be a typical summer holiday, his life is about to turn unexpected...

Unrest begins as Satō-san releases a chemical weapon onto the population. People begin trying to attack the families of Ajin. Nagai saves his sister with the assistance of Kaito. Nagai entrusts his sister into Kaito's care.

Although he was caught off his guard, Sato has one last plan: to kill the rest of the team.

Nagai and the group pursue the Americans and Tosaki. Izumi manages to catch up with them and ultimately rescue Tosaki. Unfortunately, this means they missed their window to catch Sato.

People from Satō's group desert and make contact with Nagai. The US plans on releasing the chemical weapons on Satō in the sewers. Tosaki is called and asked for assistance, which leads Nagai and the group to go after Satō once more.

Sato starts killing people in the lab. Kei tries to stop him and discovers that Ajin has a weak spot.

Sato prepares to attack. Ko discovers the hideout of Kei and begs for help. Tosaki gets a surprise visit.

Kei and Ko train their bodies and begin to develop strategies to fight Tosaki. Kei spends time talking about his IBM with Ogura, realizing Kei's ghost is an extreme abnormality. While they begin to strategize, Sato makes his next move taking down a plane with his second target.

Kei continues his training. Tosaki attempts to get the Minitser's schedule. The Minister refuses, which leads Tosaki to attempt to steal it. However, the American investigators interfere.

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.

Nagai and the group return after being defeated by Sato. Nagai struggles to deal with his failures. Sato continues towards his third and final wave, an Ajin run Japan. Tosaki tries to mobilize everyone once more to stop Sato, but Nagai refuses.

With the country all online assisted Tozaki employs a new tactic to deter Sato. Kei loses its disguise.
