After the death of Dabura, Gomah becomes the new king of the Demon Realm. He and Dagasu, the younger brother of Shin are watching a recap of the events of Majin Buu Saga. Dr. Arisu, the sister of Shin and Degasu joins them to ask Gomah if he will give supplies for her research just like Dabura did and gives them the idea to use the Dragon Balls to make the warriors who fought against Majin Buu young in order for them to not pose any threat to the Demon Realm. Due to the Demon Realm's Dragon Balls being protected by some robot creatures named Tamagami, Gomah, Dagasu and the creator of Demon Realm's Dragon Balls, Neva go to Kami's Lookout, but when they were leaving the Demon Realm they learn that Dr. Arisu has gone to Earth some time ago. In Kami's Lookout, Neva uses his power to collect Earth's Dragon Balls. Dende tries to make resistance but is knocked by Dagasu. Meanwhile, the Z-Warriors are celebrating Trunks's birthday at the Capsule Corp. Dagasu summons Shenron and Gomah wishes for the warriors who fought Majin Buu to be turned into kids.
