Everybody believes the character to be a beautiful female ~~courtesan~~ (EDIT: teahouse worker, got two characters mixed up) literally up until the last page of the most recent chapter, but reveals they're actually a man, and a master swordsman, but, in their own words, "a female at heart".    Unlike other characters, this one wasn't done to an extreme stereotype to "show" they're different. Other trans characters are pretty heavy on the stereotypes. Google "Bon Clay" or "Emporio Ivankov".
