A grown up version of the series's main character, Neptune. Unlike the original Neptune, this version is a normal human. She first appears offscreen (voice only) in the true ending of Victory/Re;Birth 3, with her first proper appearance in Megadimension Neptunia VII.
This Neptune is from the Ultradimension, but never became a CPU. In the true ending of Victory/Re;Birth 3, she encounters and captures Croire. She later appears in Megadimension Neptunia VII, having used Croire's dimension travel ability to travel to the Zero Dimension.
