What I was getting from ElfTengu's earlier posts was why don't the Koryu "get with it" and train to prepare for real, MODERN fights or somesuch. Fair question.
In my opinion, that way lies death for Koryu. "Getting with it" is exactly why the martial traditions of Renaissance Europe died out. There are no longsword masters alive today, no Ringen masters, not even any rapier masters. Koryu are already dying out in places, because the Japanese aren't learning from the history of European martial arts. There's no need to find more nails and coffins. The idea is to preserve the ryu. Nothing else matters. When you make modernity your goal, then you lose the longsword and get stuck with foil, sabre and epee. I'd rather have all of it.
