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.

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.
