Sunset.
Episode Description:
After a wild chase during which the jet attempts to kill them, Ibara manages to shoot it down after which it crash lands into a lake stadium. When the Coppelions arrive at the stadium, the mercenaries had just died. As they investigate the jet, they discover barrels of radioactive waste in the lake, now realizing what was going on. The mercenaries were working with Yellow Cake, a recycling waste company who had secretly been dumping radioactive waste from around the world into Tokyo, knowing no one would be coming there, which ended up causing the recent rise in radiation levels. Ibara becomes angry upon learning about this, while Denjiro feels that everything is his fault and wants to atone for his faults. Fearing that Denjiro might kill himself, Ibara tracks him to a shrine only to find him removing his helmet. With only ten minutes before the effects of the anti-radiation properties of the Ether bullet injection are gone, the Coppelions quickly drive him to the airfield to be evacuated by Onihei. However, the helicopter has yet to arrive. Denjiro tells everyone to just let him die to atone for his sins, but Ibara refuses. With a few seconds left, Onihei's helicopter arrives. He throws another Ether bullet to Ibara in order to save Denjiro. As the helicopter gets Kamata and Granny Ayame on board, Onihei helps Denjiro get on board despite Denjiro being indirectly responsible for his family's death during the meltdown. Denjiro apologises to the girls for the world they now live in and gives them a list of the other survivors in Tokyo. As the Coppelions continue their mission, Aoi and Taeko assure Ibara that they will always be there for her.
