My Budo (trans. "Way of War") is "Dux Ryu" that as its founder and head of family I have the authority to issue a document of transmission in my way Dux Ryu... Ninjutsu is again a 20th Century umbrella term denoting ancient rooted and stylized "tradecraft." There exist no Menkyo for NInjutsu in and of itself is what I was referring to, understand better? Here's the example a person says "Im a 10th Degree in Karate... and have a Menkyo for Karate in and of itself without naming which style aka Budo is a red flag. Someone says they have a Menkyo in a particular form of Karate (Goju, Kyokushinkai, etc.) is more appropriate.
