This is really, really cool. I've trained in a little bit of Kendo, mostly through Aikido, but I never got into anything of Musashi's style or teachings. This is very, very interesting. It's just the slightest bit front-loaded, and as it is I don't see anything that provides for the ability to move/full attack, which most TWF classes should have access to IMHO. I could just be oblivious, but still.

Also, there's another class already called Kensei. Some variant fighter, I believe. I truly believe this deserves the name more than its predecessor, but if you care that much, well, now you now.

Overall: Applause. That is all.
