What Chris said! Frankly you are just training and right now your training has nothing to do with any form of Ninjutsu so you should just drop that idea. Unless you go to a Training Hall of the Bujinkan, Genbukan, Jinekan or as Chris said a legitimate off shoot then you are not training in this system or lineage. That is the current reality! Now that is not implying that your training is not good just that you are not training in this lineage. Now if you are sincere and really want to train in one of the X-Kan's then you will find a way to make it to one of their dojo's and learn from a qualified instructor. There simply is no other way!
