David J. D'Antonio is a known fraud. He has been presented with questions many time to simply prove his claims of being the 16th inheritor of Koga Ryu Wada Ha Ninjutsu. Any professional practitioner would be happy to present their credentials. If you cannot earn your students' trust up front, how ever are they supposed to trust you?
Mr. D'Antonio claims to have access to Fujita Seiko's (the reputed 14th inheritor), yet the very scrolls he lays claims to are known to be in a museum in Japan (my apologies for not knowing the name of the museum, but it is researchable).
Many people have asked Mr. D'Antonio to substantiate his claims only to get continually evasive answers. If evasive answers alone can make one a ninja, then he, indeed, is a "grandmaster."
