From video serie of Kuro-obi world by sensei Naka. He shows four sequences of bunkai out of the heian yonand (pinan yondan) kata with the actor Joey Tee. Very simple an direct application for real self defense use.
This is a very interesting kata demonstration of the old kata Bassai Dai for Shotokan with the young girl Mahiro Takano and Shito-Ryu with Rika Usami. Both have a high level reached. We can see one karate family with her sisters, oss.
