Koden Ryu is been around for a long long time. I understand it must SUCK for you who purposely blind yourself because you hate Koreans and to also find the oldest shurikenjutsu method was from KOREA (culture thief?) again. But that's just the truth popping out it's head again.
Is it a surprise they have KUNAI gata? You tell me who the authentic Shuriken practitioners are. I'll ask them to show me the authentic throws along with it's history and I shall also share what was taught to me along it's real history. Lets compare and educate one another. Fair enough?
