Hi!

Thank you for another chapter.  This is one my favorite ongoing
stories.  I don't have a lot of C&C but here are a couple of
'problems' (well, to me anyway) I saw:

Ok, let's see what you've got...

     "Ryouga is a fine martial artist, and a good teacher.  He has
the patience to train, and the ability to push them to their
limits,"  Cologne looked out the window again.  "Not everyone has
the drive or skill it takes to master the techniques that he knows.
And considering how depressed the boy is most of the time, it's
just as well he has an outlet for that,"  Feather looked confused
at her statement.
     "What do you mean?"
     "Depressed people often turn self destructive.  Ryouga's
spirit is too strong for that, so he found purpose for himself
through martial arts,"

A comma?  Is this just a typo or did you leave something out?

Something like ". . . through martial arts, " Cologne said,
speculatively, her eyes half closed in thought.

Originally, I'd say it was an escaped typo, but your wording there
adds a little character to it.

     "Wow, I didn't know he got depressed that easily," Cologne
turned back to Feather.

And who is speaking here? Feather or Cologne?  Normally, if I see a
comma-endquote-space then a proper name it usually indicates the
person doing the speaking.  But that doesn't make sense from the
context.

I'd try it like this:  "Wow, I didn't know he got depressed that
easily, " Feather sighed, softly.  Cologne turned back to Feather.

I see what your saying.   It was obvious to me who was talking...

     They broke apart, and then returned to the rapid exchange of
punches and kicks.  They were so engrossed in their battle that
they didn't notice how close to the door they had gotten.  With a
startled yell, they fell outside into the rain.  Akane stifled a
giggle when she heard the loud complaints Ranma-chan aired.  Akane
stopped giggling when she heard an unfamiliar female voice answer
Ranma-chan.  Akane and Feather rushed to the door and looked out
into the rain.  Sitting next to Ranma-chan was a blond haired girl
that had the same expression of disgust on her face.  Akane was
about to ask who it was when she noticed that the girl was wearing
the same clothes Ryouga was during the fight.  Ranma-chan looked up
at Akane's expression, and then cast her gaze over to Ryouga-chan.
     "I guess the moon ain't full anymore, eh Ryouga?"

I don't like excessively long paragraphs.  Comes from have to
constantly read dull, wordy, sleep-inducing government regulations,
SOP's, manuals, et cetera.  Also you're use of proper names is
repetitive.

It is a bit long of a paragraph isn't it?  I'll be sure to use the
revisions you
mentioned before posting to the RAAC.

All of this is, of course, only my opinion.  Take what you can use
(if any of it) and toss the rest.  I look forward to the next
installment.

You have given me a good deal of stuff to work with, not only for this
chapter, but it will help me polish future chapters even better.
Chapter 9 is underway, and may be out next month.
Thanks for reading and for your comments!
