This novel presents an alternate setting in which the world of GJ-bu is a story written by Kyouya Shinomiya, a member of the KB, a club where every member writes stories. All characters from GJ-bu appear in the world of KB-bu, though their personalities differ slightly from those in GJ-bu. Mao writes action stories and does not bite Kyouya's head; Shion writes erotic doushinji and is more assertive toward Kyouka; Megumi writes stories featuring an evil princess as the main character; and Kirara, who is shy and quiet, creates picture books.
