As a computer virus based on Pac-Man invades Japan, a group of doctors attack Genm Corp and begin a wave of terror using stolen Proto Gashats. Ghost and Ex-Aid find themselves at the center of the fight in an effort to protect those most important to them. But they aren’t alone, as Heisei Riders from the past join them to stop Dr. Pac-Man!

After chasing the mysterious Kamen Rider Dark Ghost, who had suddenly appeared, Takeru Tenkuji arrives at a strange village full of historical figures. Attempting to gather 100 Eyecons, Alain’s dead brother Argos - Kamen Rider Dark Ghost - wishes to create the Ultimate Eyecon and turn everyone on Earth into ghosts. Meanwhile, Makoto’s father Daigo Fukami is seen in the village. Transforming into Kamen Rider Zero Specter, is Daigo an ally or an enemy?

Takeru Tenkuuji, the son of a ghost hunter, is murdered by the evil Ganma and resurrected by a mysterious hermit and bestowns upon him the Ghost Driver and a Ghost Eyecon, an orb-shaped device which can see ghostly creatures like spirits of dead creatures, Ganma, and other Riders. The hermit tells Takeru that he has 99 days to gather 15 additional heroic Eyecons to be brought back to life permanently, and must fight the Ganma as Kamen Rider Ghost to obtain them.

During the events of Kamen Rider Ghost, the Prince of the Ganma reflects on his history and origins.
