The episode begins with a general retrospective of the series, covering Goku's trajectory from childhood to the Buu Saga. During this retrospective, we see Gomah and Degusu watching reanimated scenes from the Buu Saga, which last about 15 minutes and include all the fights and important moments. While studying the warriors and the Dragon Balls, it is revealed that, in Makai, they already have three balls, which are being guarded by super warriors; these balls are enormous, the size of people.
The party in question celebrates Trunks' ninth birthday, which indicates that "Daima" takes place in 775, one year after the Buu Saga, when Trunks was only eight years old. However, Kibito and Shin are unfused in this new arc, as Buu absorbed them, separating them in the same way that happened to Vegito; it is believed that this was done by Mr. Buu, Satan's Buu.
Gomah and Degusu use portals to reach Earth, but these portals have the ability to take them anywhere in the universe(s), which they refer to as the "outside world". They intend to grant specific wishes, although they have not revealed which ones, only mentioning that they are related to Dabura's father. To facilitate their plans, the duo visit Dende, accompanied by a Namekian named Neba, who possesses powerful abilities, such as gathering the orbs in just three seconds and revitalizing them, as they were deactivated due to having been used in less than a year.
One of the wishes the duo makes is to turn everyone into children. Meanwhile, Goku and Vegeta are involved in a fight that occurs during Trunks' birthday party.
