Although I know that Akame ga kill is popular. I have seen a decent amount of fanfics and a lot of fanart of the main cannon characters. But what I found really peculiar is the scarcity of Original Characters by fans. Something like akame ga kill that is fairly popular is usually bound to have OC's made by the fandom. Now I can understand why, some people would dislike Original Characters because of their bad experiences with Sues/Stues. But then against even sturgeons law applies to character creation as much as any other type of medium.
Of course I am in the middle of making a earth born OC for a AGK fanfic myself. But I have to ask you guys, why are OCs so rare in this fandom. what kind of advice would one give to make a OC for a AGK fanfic. The Idea for my oc comes from various similar good/decent fanfics and the agk fanfic strange worlds.
