In Neptunia: Sisters VS Sisters, you play as the Goddess Candidates, led by Nepgear, who awaken from a two-year-long slumber to a Gamindustri that has been upended by a treacherous threat called the Trendi Phenomenon. While they've been sleeping, the citizens of Gamindustri have turned to using a new device called the rPhone as their main method of communication as they've been unable to leave their homes while monsters lurk outside.
