Magical Girl Lyrical Nanoha

The protagonist, Nanoha Takamachi, is an ordinary third-grade elementary school girl. While heading to cram school with her friends as part of their daily routine, she discovers Yuuno Scrya, a ferret from the alternate world Midchilda (also translated as Midgechilada). Through telepathy, he informs Nanoha that he came to this world to recover the Ancient Artifacts (relics of a highly advanced civilization in parallel dimensions) known as "Jewel Seeds" that he had excavated. To protect the town from potential destruction caused by Jewel Seeds going out of control, Nanoha decides to step in and recover them on Yuuno's behalf. Little did she know, this was merely the beginning of a series of events. They encounter a mysterious blonde magical girl who shares the same goal—recovering the Jewel Seeds. Who exactly is she...?
