Perhaps the translation of 'young girl' is a fanfic convention? ^_^

  Viz calls it that in their dub, and the same thing appears in the Viz
translated manga.
  I've also heard it translated as "virtous" girl, and well.. you can
think of that as you want to.

  With Ryouga I simply assume that he turns into an adult pig that is
normally that size.  Not every pig is a huge beast.
