Real Ninja (Authentic 忍者-間者 materials)

These are a "little" of what I know about authentic Ninjutsu I share with you. I hope you research and discover the way of life and the methods of real Ninja as taught to me.

I understand the censorship annoys some of you. But a real PATIENT person would seek and also watch and be able to come to an understanding. That's what Ninja do...research and also INVESTIGATE
rather than talk trash and become a poor theorist and that's the truth...Forgive me.
RATE if you want more clues and hints. Thank you
