After the murder of their parents, 11-year-old twin brothers Thor and Rai Klein are sent away from their home planet. They find themselves awakening on the terraformed planet of Chimaera, where carnivorous plants dominate and the few humans who live there are divided into four groups known as "Rings." Soon after, they meet a young man by the name of Zagi, and the twins learn that only the "Jyu Oh Sei"—the one who conquers these four Rings—is allowed to leave the planet.

Driven by the desire to return home and discover the truth behind the death of his parents, Thor resolves to survive in the harsh, merciless environment of Chimaera. However, he quickly learns there is more than meets the eye in this strange ecosystem. As Thor is swept up in the politics that entangle the Rings, he uncovers more about his parents' murder, and ultimately, humanity's fate as a whole.

Not very well known or popular, Jyu Oh Sei is a hidden gem. A relatively short anime, this series went way beyond my expectations in nearly all respects.


Jyu Oh Sei dispels the myth that a series has to be long in order to be good. It's only 11 episodes but the plot moves very fast and a lot of stuff happens at a good pace.

The story starts off with two twin brothers barely into their teens abandoned on a prison planet after their parents are killed. It begins as a "survival tale" with Thor, the elder brother, being the protagonist, and swiftly transitions into read more

Jyu Oh Sei has stupid names for characters like Thor, Odin, and Zagi of Iliad, but if you can get past that ridiculous attempt at symbolism, and other miscellaneous missteps, you'll hopefully find yourself entertained by this fast paced epic adventure.

On a colony planet far from Earth, two brothers stumble upon their murdered parents and are knocked out by gas. They wake up on a planet loaned from whoever built the sets for King Kong and Little Shop Of Horrors. That's right; the jungle tries to kill you every five minutes!

Jyo Oh Sei is a good (maybe even great) 29 episode show squeezed into 11 episodes. The result isn't pretty.

The foundation of the plot is a big 'ole mess of second rate science fiction concepts, including The Plant Planet, The Prison Planet, The War Between the Sexes, and others that it would be spoilerish of me to reveal. Seriously, this story kept reminding me of the Golden Age SciFi I've read. The difference is, those stories (well, the good ones anyways) fully explored their concepts and were able make interesting situations out of them. And perhaps the Jyu-Oh-Sei manga manages to read more

Aw~~, Jyu Oh Sei...So special ...
To start, the story. I've never imagined that kind of story could exist.
Mixing Sci-fi with he...Hum...how to say it... with a "king of the "animals"", was very sought.
So: Thor and Rai, 2 little twins with blue eyes, pale skin and grey hair, discovered their parents, dead. Dispatched in an unknown planete -by important people (but who?That's a really important question in this story)-, where the law is simple: the stronger, who rule on every people on this planete (called Chimera), and rule on the "special" flora of Chimera, will be able to quit it...
After a little time to think, read more
