Three hundred years ago, spatial rifts opened, ushering Earth into the Age of Beast Taming. Poor student Brady Hill, to raise money for his sister Ellie Hill who suffers from Soul Freezing Syndrome, awakened only an F‑rank talent on Awakening Day. Yet he unexpectedly contracted a husky with ancient chaos bloodline—also named Brady Hill—and activated the "Mind‑Break System." By making opponents collapse and break their defenses, he could collect emotional energy to add points and evolve his beasts. Relying on his husky's demolition, taunts, and mental pollution, Brady Hill turned the tables and earned money in school competitions, the Underground Arena, and Wilderness Trials. As the Beast Cult's conspiracy to create Beast Hordes surfaced, he led his quirky divine pets to protect the city and save his sister, eventually gaining admission to Metropolis University and embarking on a greater beast‑taming journey.
