In a spectacular finale, Super Saiyan 4 Goku engages in an epic duel with the Hell King Gomah. The battle culminates in an overwhelming Kamehameha that not only pierces Gomah's body but also penetrates dimensions. Despite Piccolo's failed attempt to remove the Tertian Oculus from Gomah's forehead, the unexpected hero Majin Kuu delivers the decisive blow: three precise hits to Gomah's occiput deactivate the Oculus, allowing Glorio to destroy it. Gomah and his henchman Degesu are ultimately imprisoned in a special containment unit complete with a garden and games—an ironic fate for the former ruler of the underworld.

After the victory, Kuu is crowned the new Supreme Demon King. In a humorously political scene, he appoints Arinsu as the reluctant Vice-Queen and forms a council of ministers from allies like Duu, Neva, and Glori. Kuu ambitiously declares his intention to reshape the demon world into a "terrifying yet good place"—a balancing act between power and pragmatism.

Meanwhile, Vegeta reveals his resentment toward Goku for hiding the SSJ4 transformation. Goku admits to having trained in the form secretly after the Buu battle, sparking a typically heated exchange: Vegeta pridefully boasts about his "Ultra Vegeta 1" stage, while Goku counters with his SSJ3 achievement. In parallel, Dende plans to recruit Namekians from "New Namek" for the demon world, while Neva awaits an answer that could determine her future.

Back on Earth, Bulma eagerly hunts for "Beaut Bugs" at the Medi-Bugs Shop—rejuvenating beetles that restore skin by ten years. But the cheer turns to shock when the group discovers two more Tertian Oculuses in the store. The saleswoman reveals that a third Oculus was sold long ago—a cliffhanger hinting at new threats.

The episode closes with a touching tribute to the late Dragon Ball creator Akira Toriyama, whose death anniversary coincides with the airing date.
