Hyperdimension Neptunia Victory (2013)
Hyperdimension Neptunia Victory is a video game set several years after the CPUs and their younger sisters have prevented Arfoire's revival. All is peaceful in Gamindustri until one day, the CPU of Planeptune-Neptune-is sent to another dimension which resembles her own. This new world has only progressed to the Gamindustri of the 1980s and Neptune finds out that a group of villains called Seven Sages are trying to create a world without CPUs. With help from her new friends, including Plutia (the other dimension's CPU of Planeptune), Neptune embarks on an adventure to protect this alternate version of Gamindustri from destruction by the Seven Sages.
