Coppelion

Haruto informs the group that a massive and lethal Zone is approaching the Planet. With time running out, Ibara comes up with a last-ditch plan to evacuate everyone from the area using an old abandoned train.

While heading to the hospital, Ibara and her team run into Cleanup Crew members Kanon and Shion Ozu, otherwise known as the Ozu Sisters. But to Ibara’s surprise, the Ozu Sisters turn against their former classmate…

Ibara is critically injured after getting caught in a blast caused by the 1st Division’s tank. Thanks to the efforts of Haruto and Taeko, Ibara manages to pull through, only to learn that a guilt-ridden Aoi has now secluded herself.

Aoi’s careless action results in her being captured by the 1st Division. Realizing that the enemy is actually after the Coppelion and not the survivors, Ibara tries to rescue Aoi, only to be knocked unconscious by one of the men.

While heading to their next destination, the girls encounter a father and his pregnant daughter being attacked by a group of armed men.

The Coppelion succeed in bringing down the monster crow, which then crash-lands in one of the Zones. When the girls arrive at the site, they discover that a company named YELLOW CAKE is responsible for dumping high-level waste into the Old Capital.

Vice Principal Mishima learns from the rescued Tanizaki about a man known as the Delivery Man believed to be their leader. Meanwhile, the girls follow a lead that unexpectedly takes them to the Delivery Man himself.

The girls encounter a man searching for his missing child. Hearing that the child may have wandered into a dangerous area, the girls rush to find the child before it’s too late.

In the not-so-distant future, a catastrophic event has turned the old capital of Japan into a wasteland, forever changing the lives of its people. Decades later, three schoolgirls set foot into the now forsaken city.
