Sci-Fi/Modern/Mahou Shoujo Titles

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.

Several months after Nanoha first became a Magical Girl, she still is unable to personally meet with her new close friend, Fate Testarossa, who is being tried in the Space / Time Administration Bureau for her association in the Lost Logia case. They still communicate through video-mail and hope to see each other in-person once again. Their reunion is not a happy one, unfortunately, as several people who call themselves "Velka-Type Knights" battle Nanoha above the city. Their objective is to fill the pages of the Book of Darkness by stealing the magical power of anyone they can find. Nanoha and Fate must once again team up to stop their plans and save the world.
