Histoire's role is similar to the first game, being sealed away in a tome and requesting Neptune to find the four Key Fragments. Since the original goddess was not Arfoire, who is human in this game, Histoire was not created by Arfoire, but she helped Arfoire to raise the four CPUs. Unlike in the original, Neptune declines to have her prior memory restored, fearing it would damage the friendships she made with other CPUs while amnesiac. In Chapter 8, if certain Remake plans are completed, she will introduce the newly CPU Candidates to their respective sisters.
