Kaito,a brilliant but overworked astrophysicist, dies in a lab accident, only to be reincarnated as Kairo, a low-class Saiyan infant on Planet Vegeta, a decade before its prophesied destruction. Unlike his future rival Bardock's son, Kairo's power level is a measly 15, marking him for a short, brutal life. His only hope is the "Multiverse Mandate System," a mysterious power that binds him to a cosmic contract. The System offers a path to salvation and unimaginable power, but at a cost: he must complete perilous missions across 50 different universes (anime, games, manhwa).

His latent talent? A "Limit-Breaker" trait, similar to Saitama's ability to shatter natural caps on growth. For a Saiyan, this means his Zenkai boosts have no diminishing returns, his potential has no ceiling, and his strength can grow infinitely with every battle, every mission, and every breath. Starting from the absolute bottom, Kairo must navigate the cutthroat Saiyan society, gather power from countless worlds, and race against time to become strong enough to save his people, challenge gods, and ultimately, face the System itself.
