Your partner

grasps your right forearm with both hands, his right hand round your wrist. Step back to your right corner with your left foot. Your right hand follows in the same direction. Catch the finger of his right hand with your left and lock them against your arm. Make a big circle, coming back into him with your right arm. Your hand now goes over the top of his wrist and pushes him to his right side so as to bend his elbow. Begin to move backwards at the same time bearing on his wrist. Bring your right hand towards your own stomach and he will crumple on the ground. You can immobilize him as in Nikkyo 12th form.
