Aeos, a former Supreme Kai of Time, forces fighters from every surviving timeline into a Super Space-Time Tournament meant to decide which single reality gets to continue existing. Goku's team draws on unlikely allies, including former rivals Jiren and Hit, as they face opponents pulled from alternate dimensions and eras across the Dragon Ball multiverse. Aeos is weighing the timelines on luck as much as on raw power, and her tournament is thrown off course when Demigra and his followers force their way in.
