Jyu-Oh-Sei - S01

After their parents are murdered, eleven-year-old twins Thor and Rai Klein are forced to leave their home planet. They wake up on Chimaera, a terraformed world ruled by carnivorous plants and inhabited by humans divided into four factions called "Rings." There, they encounter a young man named Zagi and learn that only the "Jyu Oh Sei"-the one who overcomes all four Rings-can escape the planet. Determined to return home and uncover the truth behind his parents' deaths, Thor struggles to survive Chimaera's brutal environment. But as he navigates the dangerous politics of the Rings, he begins to realize there’s more to this strange world than he first thought. Along the way, he uncovers deeper secrets about his family’s tragedy-and humanity’s destiny.
