Jupiter is one of the Original Dozen, the group who first settled in Mars. He was the ruler of his own dome, until he was defeated and killed by Layla Ashley in a fair fight.

Mars has been colonized and is a world where children have been replaced by robot servents known as 'dolls'. Layla is a skilled fighter with a tragic past who travels about the world. Her companions are Nei, a strange and unique doll with some unknown ties to Layla, and Speedy, who is a doll breeder. The founders of Mars see the trio as a threat to their world, and each time they attack Layla and Nei a bit more of their mysterious past and future is revealed. <br>
