Extremely Small Fandoms, Anime & Manga

As of 2017, my Extremely Small Fandoms Post needs to split, as it was getting ridiculously long. So, while backdated, this post is a creation from October '17, and houses the specific genres of Anime and Manga for which I have five or fewer fic recommendations.
EDIT: 2020: I have a lot of catching up to do! Adding Kids on the Slope, Next Life as a Villainess, Cells at Work!, Ace Attorney, Given, Trigun, Death Parade, Appare-Ranman, Blood Blockade Battlefront.

( So much fighting and friendship (at the same time, even)... )

Extremely Small Fandoms, Literature

Mostly, this is for the kind of small book fandoms where I either loved the canon and thought fanfic wasn't too necessary, or I disliked something about canon and went looking for fix-its. If it has both a literary and television presence, then whichever form of media I prefer determines which post it goes in - it won't be in both. 
*Yes, literature includes comics if I don't follow the movies/television version(s). 
**Literature also includes mythology, as long as it isn't explicitly from Hercules/Xena fandom.
***Created in October '17 and backdated to keep all Small Fandom posts together.
****I don't have anywhere better to fit in the "fandom" for FAQ: The "Snake Fight" Portion of Your Thesis Defense. And to ignore these fics would be a crime!

( Why isn't time-travel more useful? )

Extremely Small Fandoms, Movies

I don't have too many small Movie fandoms, but they deserve their own post as of October '17, rather than being crowded into the Television post. If there's five or fewer fics, the fandom goes here. 

( View with caution... )
