I wonder why 50% of all MHA doujins seem to be gender-bender. I don't think I have ever seen such an overwhelming number of rule 63 works for any other franchise.
@Nonamewalker I'd wager it's probably due to Izuku's personality and behavior, especially in the first season, skewing people's perception of him, his emotional tendencies and propensity to cry coming off as more feminine.
It could also be just because people like it, I mean, Bowsette was a thing after all lol
