After years of relentless warfare among the realms of Gamindustri fueled by Share energy, derived from their people's devotion to goddesses, a peace treaty is finally forged by the ruling CPUs. This pact prohibits the use of military force to acquire Share energy, aiming to usher in an era of harmony and prosperity. However, despite the treaty, Neptune, the carefree CPU Goddess of Planeptune, neglects her responsibilities to indulge in games, causing her nation's Share energy to dwindle. Choujigen Game Neptune The Animation chronicles Neptune and her companions' quest to restore Share energy levels while confronting an ominous external threat that jeopardizes both the Goddesses and the very existence of Gamindustri.
