Louie is a student at a mage’s school, but secretly yearns for adventure. One night he meets a group of treasure hunters: Melissa, a Mylee priestess; Genie, a warrior; and Merill, a thief. They are in need of a mage so Louie volunteers to join them, but they decline his offer when they witness his poor mage skills. The next day, Melissa prays to her god to guide her to the hero she should serve. Her god replies that the next man she sees will be her hero, after which Louie literally falls down from the sky! Against her will, Louie is the hero she should honor and thus, Louie is accepted into their group. He is now a treasure hunter, mage, warrior, and hero?! With little expertise in anything, he can't possibly be of much use!
