@Ixiaz Didn't Rance already did this exact scenario?
As Akiko have mentioned, Kenshin being a women was a historical possibility or to be frank, conspiracy theory. The evidences presented are akin to flat earther pointing out evidences that fit their theory and ignoring everything else. It does spawn quite a peculiar trend in Japanese fiction. I'm not complaining however, I like Akiko's works. If conspiracy inspires her to create, I would donate to conspirator.
