Fictional portrayals are thus inconsistent with history, fact, or plausibility. In a traditional narrow sense, "fiction" refers to written narratives in prose – often referring specifically to novels, novellas, and short stories. More broadly, however, fiction encompasses imaginary narratives expressed in any medium, including not just writings but also live theatrical performances, films, television programs, radio dramas, comics, role-playing games, and video games.

The stories are linked only by the number 9 in some way, typically taking the form of a door marked with the number 9, and a brass hare statue that is in the background of all episodes.
