Neptune embarks on a journey to save Gamindustri by collecting the Key Fragments to free Histoire and defeating the former goddess known as Arfoire. It is then that she hears the call of Histoire, requesting for her help before waking up and finding herself in the nurse-in-training's apartment who goes by the name of Compa. Hyperdimension Neptunia follows the story of Neptune, who has become an amnesiac after being defeated by the other Console Patron Units (CPUs) in a 3-on-1 match and being banished from Celestia to the world below.
