An interesting premise couched in okay prose. The fic isn't laden with
too much filler, and remains focused and interesting from beginning to
end.

The idea that the Axis won a world-wide victory is ridiculous beyond
words, but the alternate world is interesting. It needs to be fleshed
out more, but mind you don't get distracted.

The Axis didn't.  This is some kind of alternate world where Japan 
started expanding instead of going isolationist, and thus was a 
participant in the Age of Colonisation along with Britain and France.
Note that among the divergences is the defeat of the ever-despised 
American rebels (possibly because the French were too engaged with some 
kind of conflict with the Japanese to give the rebels any support)

The possibilities of this fic could have been explored better--a direct
personality exchange would have been more conductive to what you were
doing in these chapters, and it would have provided a great vehicle for
that world description I mentioned earlier. Perhaps you can work that in
in later chapters. Don't limit yourself to Ranma, get the whole cast
involved.

Gonna be tough when he has to work within the limits of his plot device.

You're off to a good start. Don't lose the trail. I would like to see
this fic continue.
