I am a fanfiction writer that is currently in various fandoms, and writing refer inserts for a lot of them. I even end up drawing for said stories so I have actually begun to put time and effort into much of what I've written. 

Not only that but I am in a lot of other fandoms such as JJBA (JoJo's Bizarre Adventure's), BOTW (Breath of the Wild),  TWST (Twisted Wonderland), Promare, Haikyuu, Little Nightmares, Houseki no Kuni (Land of the Lustrous), Jujutsu Kaisen, MHA (My Hero Academia), Ninjago, and a few other fandoms. So it's likely that I make a crossover fic at some point.
