Jyu-Oh-Sei: Planet of the Beast King

After their parents are murdered, 11-year-old twins Thor and Rai Klein are exiled from their home world and awaken on Chimaera, a terraformed planet where carnivorous plants thrive. Human survivors are split into four rival factions called “Rings,” and the brothers soon cross paths with a young man named Zagi. On Chimaera, there’s only one way off: become the “Jyu Oh Sei,” the conqueror who unites the four Rings.

Determined to return home and uncover the truth behind his family’s death, Thor fights to endure Chimaera’s brutal rules and unforgiving wilderness. As he’s drawn into the Rings’ power struggles, the planet’s strange ecology—and the conspiracy surrounding his parents’ murder—begin to reveal ties to something far larger: the future of humanity itself.
