In a giant castle in a mysterious world, two shady Majin, Gomah and Degesu, watch a monitor; they head to Earth to execute a certain conspiracy.

Goku and his friends, who have been turned small due to Gomah's scheme, prepare to go to the demon world; Goku collects his Nyoibo and looks forward to a new adventure; the mysterious young Majin Glorio appears.

Goku, Supreme Kai and Glorio search for Dende and King Gomah in the Demon Realm.

Forced to make their way through the Third Demon World on foot, Goku and his companions stop by a lone drive-in on the way; there they encounter some strange souvenirs and a rather chatty and quirky Majin woman and her husband.

The masked Majin who appeared before Goku and his companions is a young girl named Panzy; while Glorio gives her the cold shoulder, Panzy insists on acting as their guide.

After encountering the Gendarmerie, the wardens of the Demon Realm, the four are forced to camp in a cave where they encounter further trouble; the enigmatic Glorio unleashes lightning magic against Goku to resolve the situation.
