Well, if you follow the link it seems that not only is the school not ninjutsu, but the name and such is bogus. It is kind of what a lot of us have been saying for a long time. This art was put together in the 20th century. He does not seem to have been taught a family art. He instead took a little of this, a little of that and knowingly lied about where it came from. Ninjutsu sold and so he made up a story about it. Not someone I would trust or learn with even if I had not heard about the incident between him and Donn Angier.
