The game continues off from its predecessor, Hyperdimension Neptunia. In the land of Gameindustry, there are four nations controlled by "CPU's". CPU's are the goddesses of these lands; Planeptune, Lastation, Lowee, and Leanbox. Tragically, the CPU's have been outwitted by the evil ASIC who now intends to control these nations with the dark power of piracy. Rendering the goddesses helpless in a trap of energy-sucking cables, their remains a glimpse of hope, as Nepgear, the CPU candidate of Planeptune, charges into battle alongside Uni, Ram, and Rom to free her older sister Neptune and the rest of the CPU's, in the hopes of restoring peace to Gamindustry.
