Choosing a character and which character outfit to cosplay from Fate/Grand Order is like walking into a huge store and not worrying about not having enough choices. It’s not easy to run out of characters and character versions to cosplay. Nevertheless, it is not impossible that cosplayers may end up finding themselves in the same outfit because when it comes to favorites everyone’s pretty much into the same thing.
One of the most cosplayed and photographed characters of Fate/Grand Order is Shuten Douji. The character is described as the assassin servant allegedly known to be one of Japan’s three great monsters. She is obviously not human but a demon. There may be less cosplays of this in conventions for obvious clothing reasons, but evidently there are plenty of photoshoots from different cosplayers an here is another one from weibo user, 妖少you1 .
