This is a multi-degree black belt teaching Sunsu kata bunkai for self defense. This is Grand Master Shimabuku's personal kata, which is supposedly the most advanced empty hand kata in Isshinryu karate. Note the hyper-extended opponent's elbow, and then the reverse elbow to the opponent's kidney. This would probably end an MMA fight in one maneuver, and it will certainly end any street fight.

There's more than one interpretation of this sequence in the kata, but they are all devastating, and some of them are banned in MMA.

For example, the low hand in the sequence can be grabbing a man by the testicals and lifting and throwing him by gripping his nuts, which will be both crippling and permanent injury.
