An enormous cylindrical alien spaceship, which people call "the Bell", descends upon Earth one day. Multinational military forces attack it, but the Bell's defenses easily vaporize all human weaponry. The story takes place one year afterwards. The Bell, which seems to have no living crew, has begun sending out robotic probes to explore and analyze human civilization and all of the aspects of it. For most of the series, the Bell hovers quietly above the ocean, several miles from Tokyo. It had soon became apparent that the Bell's defenses only destroy whatever attacks it first. As such, most people have now adapted to the Bell's presence on Earth and are once again going about with their everyday lives, just making sure to stay out of the way of the Bell's probes when they pass by. A lot of people, however, due to a message sent by the Bell, believe the Bell may eventually attack and conquer Earth, and are working to figure out a way to stop it. Kitanohashi High School has a small group of students called "The Magic Users Club". Most people think the five club members only learn how to do regular parlor tricks, but only its members know that they learn how to do real magic. The president of the club, Takeo Takakura, started it when he found a box containing a grimoire in a cave by the ocean. Using the knowledge from the book, he was able to teach the other club members to perform magic. Takeo himself believes that the Bell will eventually attack Earth, and decides to combat the alien “menace” using this magic, despite inadvertently revealing the secret of the Magic Users Club's performing of real magic to a pair of journalists, who also want to stop the Bell, when they witness the club's first foray against it. These two become the only people on the outside to know about the club's secret. A young girl named Sae Sawanoguchi goes to Kitanohashi High School and belongs to the Magic Users Club, where she learns how to use magic that will soon become trade. The town that she lives in has never exactly been attacked, being in place in the city for a year to date. She has yet to discover the true strength of her magical ability, and because of her unintentional clumsiness, none of her friends realize it either. What would be really helpful to Sae would be that if something were to happen that would let her fine tune her talent, and the club's mission to stop the Bell may be her chance to do that.
