a snake fujoshi's realm

for international fanworks day 2023, i decided i was going to make a #ficrecs of some of my fave fusions and crossovers over twenty years of fangirling. unlike most of my other rec lists, these will be sorted by themes and not by rating. also, i'll note if a fic is complete or incomplete or ongoing (i.e. updated within the last year). ten recs have a ✵ which are ones i really, really, really fucking enjoy and hope you will too!
