For three years, the CPUs of Gamindustri and Nepgear, the younger sister of Planeptune's CPU Neptune, are all held captive within the Gamindustri Graveyard after a battle with CFW Magic ends with them being defeated. But when Compa and IF manage to enter the graveyard and rescue Nepgear, it is up to her to seek help from the CPU Candidates of Lastation and Lowee in order to free the CPUs, stop the ASIC, and ultimately defeat Arfoire once and for all.
