Jyu-Oh-Sei

After their parents are murdered, 11-year-old twins Thor and Rai Klein are forced to leave their home planet. They awaken on Chimaera, a terraformed world ruled by carnivorous plants and divided into four human factions called "Rings." There, they meet a young man named Zagi and discover that only the "Jyu Oh Sei"-the one who unites the four Rings-can escape the planet. Determined to return home and uncover the truth about his parents' deaths, Thor fights to survive Chimaera's brutal environment. But as he navigates the tangled politics of the Rings, he realizes there are deeper secrets hidden in this strange world-secrets tied to his family's past and the future of humanity itself.
