Nepgear had a really rough time during the route of conquest and at the end between her and the Deity of Sin, much more was taken than originally thought but what happens after the battle? (I recommend that you know the series so you know what the characters look like as I'm not a good describer)

This takes place not to long after the True Ending of Megadimension Neptunia VII, the current Nepgear is away with the other CPUs on a training journey while Neptune decided to stay as Uzume decided to stay along with Neptune they see Nepgear in the Planeptune park, but is it really Nepgear?
