Sci-Fi/Adventure/Animals Titles

On a Mars covered in ice and oceans, people have learned to survive by building large floating city-ships in which they can live. And by using submarines to travel beneath the ice and harsh winds that rage overhead, humanity has been able to develop a global community. But during a distant galactic war, Earth looked to Mars as important water resource to support their war efforts. Now that the war is over, Earth still values the wealth of resources that Mars provides, and is reluctant to release their firm control over their smaller step-sister.

Takamachi Nanoha is a 3rd grader elementary school girl, who lives with her parents and her older sister and brother (last seen in Triangle Heart). One day after school, she hears a voice in mind, which leads her to rescue a small animal (a ferret?) in the forest. The animal is actually an archeologist-mage from another world, named Yuuno-kun, who is attempting recover 21 dangerous Jewels Seeds that are scattered across the Earth. Yuuno had been fighting a loosing and desperate battle with a magic beast that emerged from an activated Jewel Seed, and he asks for Nanoha's help (and magic) in assisting him to defeat the beast and in recovering the other Seeds. So, with Yuuno-kun's help, and by activating the magic in the jewel raging heart', Naoha can transform into a magic girl, complete with a magic-power-staff, to save her city from the dangers of the Jewel Seeds.
