Okay, I genuinely don't know how to feel about this chapter. On one hand, this chapter easily lands as one of the cutest Genderbender/Trans Girl chapters I've read in a long while. On the other, when did Hikaru become a girl!?
Like I know the gender swap was always a thing, but Hikaru has always been a guy forced to be a girl, as opposed to say Kaede. And I know that the whole "forced to be a girl" is a core trope in GB works, but usually the character in question actually likes being a girl and is merely in denial.
The best comparison I can think of is contrasting Ranma and amnesiac Ranma. Same person, same curse, but you can just tell one is a guy cursed to be a girl and the other is a girl cursed to be a guy.
