In a distant world called Educity, everybody does nothing but study and work. Nobody has thought of changing the peaceful, orderly and rigid system; nobody has considered the meaning of life. This is why the Goddess appoints five twelve-year-olds to embark on a quest for true wisdom. They leave their homes and venture into an unknown world, where they go through precarious adventures, encountering everything from magic to ancient treasure. But at the end of it all, how will they save their silently suffering fellow Educitizens?
