Ruuan&#039;s role as opposed to Shaorin&#039;s is not to protect Tasuke but instead to make him happy which she does by giving inanimate objects life to do her bidding. In the manga she gets herself a job as Tasuke&#039;s homeroom teacher. Ruuan and Shao are sworn rivals and conflict often occurs as their roles of keeping Tasuke &quot;safe&quot; or &quot;happy&quot; aren&#039;t always equivalent    (Source: Wikipedia)

14-year old Shichiri Tasuke is your ordinary junior high school student- well, sort of. His life is a little lonely, since his family has left him alone at home while they go travel the world over, only occasionally sending letters and postcards. 
This lonely and uneventful life is shaken up the day Tasuke receives the magical Shitenrin ring from his father in China. From out of this ring appears Shao Lin, the Guardian Angel Getten. She proclaims that she is here to protect her new master from all forms of danger and will stay by his side forever. 
But having been locked in the Shitenrin for hundreds of hears, Shao knows nothing on the modern world. Sometimes it seems she causes MORE problems than she solves. Now, Tasuke must learn how to handle this beautiful, naive and magical angel.
