Description from AniDB:
An alien lifeform, in the shape of a bell, descends on earth. Although the entire world`s militairy hasn`t been able to defeat it, it doesn`t seem like it`s trying to bring anything bad to earth. Round `Bells` from about the size of a small house appear in the normal world, and they adjust themselves to regular life; waiting for a trafficlight before crossing the street, waiting in line at the supermarket, and so on.
The people in the Magic User`s Club don`t believe that it`s as innocent as it seems, and the club president goes off, together with his vice-president, and their three new members to defeat this Bell - not even mentioning that half of the users isn`t even able to fly yet!
