It's the little sisters to the rescue as Nepgear leads the charge against Arfoire's monsters. But with their older sisters sinking further into darkness every second, can they do anything in time to help?

The gang learns more about Plutia, and Neptune's very worst, most hated enemy appears.

Neptune's maybe having a tiny bit of trouble bouncing back, and Plutia's maybe getting a tiny bit irritated about it. Soon, though, Gamindustri finds itself facing a problem even bigger than Plutia's rage...

Eden acts on its bold proclamation and invades Planeptune, but Neptune is too upset to fight, leaving Nepgear on her own. The other CPUs aren't able to run much interference, though, because they've got Eden problems of their own too.

It's the final battle, and the fate of Gamindustri is on the line!
