Nanoha Takamachi, a girl in 3rd grade at an elementary school, lives with her parents, who run a coffee shop, and her older sister and brother, who attend high school and university, respectively. Nanoha's regular life changes when she hears a voice calling to her on the way home and ends up rescuing an injured ferret. This ferret turns out to be a transformed boy named Yuuno, an archaeologist from a distant world, who enlists her aid to seal twenty one powerful artifacts called the Jewel Seeds. They come from his home world and have the power to grant wishes but are incredibly destructive when misused. To do this, Nanoha receives a crystal called Raising Heart that grants her magical powers. As the story progresses, Nanoha learns more about her own powers as well as the other parties who hold an interest in taking the Jewel Seeds for their own. The story is set in the first half of 0065, according to the Mid-Childan calendar.
