Shichiri Tasuke is an average teenager, who lives on his own while his archeologist father roams the globe searching for ancient artifacts. One day, Tasuke receives a package that contains one of these artifacts, and from it appears Shaorin: a guardian spirit charged with protecting the person who brings her forth. Shortly thereafter, a second artifact arrives which contains another spirit, Ruuan, whose job is to bring her master happiness. Unfortunately, Ruuan and Shaorin are old rivals and they cause no end of trouble while vying for Tasuke's attention.
