In a world where magic is a reality, the young Louise is at the bottom of her class. Dubbed "Zero" by her classmates at Tristein Academy (due to her zero success rate for magic), Louise (along with all first year students) was charged with summoning a familiar; and instead of a cute magical creature, the familiar arrived in the form of... Saito Hiraga, a normal Japanese boy who was abruptly teleported from his own world?! Can both Louise and Saito come to terms with their new and complicated "relationship" and (more importantly) help Saito find a way home?
Full Metal Panic and Zero no Tsukaima have two things in common. First, they both have amazing humor, which is basically Girl getting mad at boy, for boy behaving totally inappropriate. The other is the perfect balance between action and story. Both have their moments of cool action, but also they dig really deep into the emotion life of the (main)characters. If you like either Full Metal Panic or Zero no Tsukaima, you'll definately like the other.
