I pretty much agree with what Lurker (uh, the other Lurker ^_^) said
about this one... just want to add a few specifics.

<Thoughts>

This is completely unnecessary. Your readers will figure this out from
context.

   <Finally!  I got it!  And the wish!  The last wish is all mine!>  
Onna-Ranma grinned in anticipation at what she thought would be the end of 
her cursed days.  In a perfect imitation of Kuno, Onna-Ranma proclaimed in a 

Whoa, GIRL Ranma imitating Kuno's voice perfectly? That's a little hard
to believe.

   So the sword could grant wishes.  That didn't make it a smart sword.  The 
third wish was valid.  That much it knew.  Being a magic sword, it could feel 
the magical properties of the curse emanating from Onna-Ranma.  So it knew 
how to cure Ranma.  But, it really had no idea of what the curse was.  So it 
did what seemed logical.  It followed the exact specifications of the wish.

This reads more like a direct explanation to the readers than a
narrative. Try to show this in a way that fits more as part of the
story.
