Thor and Rai are twins who live on an advanced space colony called ‘Juno’. Things take a nasty turn one day when they are kidnapped by the Federal Army’s Special Forces and abandoned on the hostile prison planet Chimera. A cycle on Chimera consists of 181 days of scorching heat and 181 nights of below-freezing temperatures – not to mention it is populated almost entirely by carnivorous plants. The convicts on Chimera have found only one means of survival – reverting back to the law of beasts. For the strong-willed Thor adjustment comes naturally; but for his naive and weaker brother Rai, things do not go as well. Thor must now use all his wits, strength and courage to endure life as a member of Chimeran society, rise above the rest, and take the only ticket off this planet: becoming the Beast King.

If you have ever read William Golding's Lord of the Flies, then you'll understand very quickly the classic theme this series is tapping into, namely survival of the fittest at the cost of humanity. However, Jyu Oh Sei swaps English schoolboys for convicts, and sticks and stones for beam-knives. As intense as it sounds, the show fails to reach its... read more

Planet of the Beast King could have made a great sci-fi / action / mystery / survival anime but because of bad storytelling it ends up being nothing but a superficial shojo romance for fangirls. Do not make the mistake of expecting action or adventure while starting this anime. The story begins with a pair of twins living in a high-tech colony, having their parents murdered and... read more
