Well, Benjamin, there were a couple of nice things about this story.
The ending was touching, obviously the whole point of the story.
However, I really, really hated your statements that housework and
pacifism are female qualities, and that if Ranma became a woman in mind
as well as body that she would automatically assume these
characteristics. That is extremely sexist, and flies in the face of
what Ranma 1/2 is all about: challenging our beliefs on gender roles.
Your story is big step backwards in that respect, in that being a woman
means you like doing housework and hate violence. In fact, nothing
could be further from the truth.
Also, how is that this affected Ranma and not Genma? Since Genam was
cursed at the same time as Ranma and Ryoga, it should have affected him
too.
There were some nice moments in this story. You could do a good story
based on this premise, if you would only avoid the sexist views on what
gender roles are.
All of the above is, of course, just my opinion.
