Coppelion

The Coppelion Healthcare Team, who are teenage girls who have been genetically engineered to be immune to nuclear radiation, are sent to an abandoned and contaminated Tokyo after a distress signal is received from the city.

The girls run into 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.

The Coppelions meet the man who's been delivering supplies and hazmat suits to the survivors, Dr. Denjiro Shiba; the girls also find out that he is the scientist who designed the Obaida Nuclear Power Plant.

Ibara manages to shoot down the jet, after which it crash lands into one of the Zones; as they investigate the crash site, they discover barrels of radioactive waste strewn around the area.

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

Aoi's careless action results in her being captured by the Ghosts of the First Division; realizing that the enemy is actually after the Coppelion and not the survivors, Ibara tries to rescue Aoi.
