A giant castle in a mysterious world. Two shady Majin, Gomah and Degesu, watch a monitor. The monitor shows Goku and the others having a fierce battle against Majin Buu. Gomah and Degesu head to Earth to execute a certain conspiracy.

Goku and his friends have been turned small due to Gomah's scheme. They begin preparing to go to the demon world. Goku collects his Power Pole and looks forward to a new adventure. Then the mysterious young Majin Glorio appears!

Goku, Supreme Kai, and Glorio head out to the "Demon Realm" first. Their plane travels through space and a mysterious dimension. They arrive at the entrance to the Demon Realm, the "Third Demon World"!

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. The group reaches a suspicious castle!

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!

Goku and his companions continue their journey. But the Gendarmerie appear and bar their way again, perhaps due to them knowing the location of the Magic Collar around Panzy's neck. Can the bond with her friends save Panzy from peril?!

The fight with a Tamagami begins! The Tamagamis are the undefeated guardians of the Dragon Balls. Seeing Goku fight toe-to-toe with one, Panzy and the others are unable to hide their surprise. As the battle heats up, what will happen?!

Rumors of what Goku did in the Third Demon World spread across the Demon Realm. To avoid trouble, Goku wears a disguise at the hotel, but they can't let their guard down in the Third Demon World. Thieves see through his disguise!

Goku and his companions arrive at the mystic Second Demon World where a giant ocean spreads as far as the eye can see! The party is amazed at the new world but is immediately attacked by Gendarmerie that have been sent by Gomah!
