Shinko-ryū (真古流, Old School Style) is a kenjutsu organization founded and headed by Isurugi Raijūta with the intended purpose of revitalizing Japanese kenjutsu through force. Despite its posturing as a "school", it would be more accurate to describe Shinko-ryū as a league of skilled swordsmen who have been drafted from all over the country regardless of which styles they use or from which schools they hail--swordsmen discovered to be of sufficient skill are given the choice to either join the organization or be slain by it. Those who choose to assimilate are privy to Shinko-ryū's true aim: the forceful eradication of the five-hundred existing schools of kenjutsu and kendo so as to make room for a new army of swordsmen whose satsujinken skills match those of the ancient "whirlwind masters"
