Well, there is a lot to say about Kendo Girl, but nothing sums it up quite like "wicked".  I am a big fan of adult themes in video games and this mod is very much for adults only.  I'll start with the major down side first, the quest is a little linear, in fact there is very little room for variation in it's play, but hey it's a home made mod you need to cut the writer some slack.  Other than that one issue the mod is excellent.  The story is dark and sexy, and the items granted from the quest are wonderful.  Also it adds a companion who is head and shoulders above most of the other companions available out there.  I would highly recommend trying this mod out.  Just remember it has a lot of required mods, so take the time to make sure you have all of them first.
