white heart is the Console Patron Unit (CPU) of Lowee and the tritagonist of the Hyperdimension Neptunia franchise. She represents Nintendo home consoles which is referenced through her appearance in both forms, her processor units, and some of her dialogue.

Neptune (ネプテューヌ Neputūnu), also known as Purple Heart (パープルハート Pāpuru Hāto), is the main protagonist and titular character of the Hyperdimension Neptunia franchise. She is the Console Patron Unit (CPU) of Planeptune. Neptune personifies a fictional Sega console, although her name was inspired by the Sega Neptune, which combined the Sega Genesis and 32X but was never released. Neptune personifies a fictional Sega console, although her name was inspired by an unreleased Sega console, the Sega Neptune.[1] The Sega Neptune was to be a Sega Genesis / Mega Drive combined with the 32X that was meant to be a stop-gap solution until the Sega Saturn was released; it was ultimately cancelled by Sega in October 1995, with Sega citing fears that it would dilute their marketing for the Saturn while being priced too close to the Saturn to be a viable competitor. In the Hyperdimension Neptunia games, Neptune does not personify this unreleased console - it was merely an inspiration for her name. It should also be noted that unlike the other goddesses in the game, Neptune's console has never been hinted to change, but rather the technology for it simply improves while the console itself remains unchanged. Another thing to note is that in the first Hyperdimension Neptunia game, for Neptune's second special attack she is seen turning into her console which in turns opens up and becomes a fighter jet that is capable of firing a Wave Motion Canon. In Hyperdimension Neptunia Victory, she is seen assuming the Fighter Jet form again in her Final Hard Form, but this time instead of the Wave Motion Canon she is shown to fire a barrage of missiles. However, during Plutia's Final Hard Form where Plutia becomes a Stealth Bomber, Neptune takes her jet form again and is shown to be firing a Wave Motion Canon alongside her. This shows that Neptune and the other goddesses are capable of assuming forms outside of their normal Human and Goddess forms. Neptune is the older sister of Nepgear. In mk2, she is captured along with Blanc, Vert, and Noire, so their sisters must step up and rescue them. Her dungeon ability, "Throw Herself" allows Neptune to throw herself into a obstacle to break any obstacle in her path in order to continue exploring(with the cost of some HP) or come by special items. Her default weapon of choice is a wooden stick in human form and an Katana when in her HDD form.
