【ようつべの朝鮮忍者コメントより】I have made a video in the past about metal forearm guards and also using leather as gaunlets but the rocket scientist is to busy talking out of his ???(where the sun doesn't shine) and acting like there is only 2 ways. Isn;t he a genius? As for the rolling and what Koreans use. You have nothing to say because you don't know anything about it Dr. Dean. You say I talk out of my anus? When will you "the authority of Korean" and "Sayaga Kooka Ninjutsu" stop talking out of where the sun doesn't shine?
