In 2436 AD, two young twins-Thor and Rai-are living on the space station Space Colony Juno. Their entire lives are turned upside down when one day they discover their parents are murdered, and then they are kidnapped and sent to a forsaken planet-the 'Planet of the Beast King'-by unknown masked men. The two of them must fight for survival in this harsh world, infested with giant carnivorous plants and populated with criminal outcasts from across the galaxy. And they must confront the 'Beast King' if they ever want to even hope of leaving the planet!
