As I see your left hand deflect mine I activate my byakuugan aswell. And before you move your right hand I punch you in the face using my momentum to increase my speed. As my punch connects with your face, since there is noway to block it since you are throwing one of your own and I have longer arms and moved before you you take the hit. But my momentum carrying through I turn my body so I glide past you and then jump back keeping low to the ground away from you.
*as your punch hits me I use the momentum to spin and strike you with the back of my fist as you glide past me*
(im taking it you hit with your right hand)
*I then jump backwards and regain my stance*
Not bad, but now its my turn
*I run towards you and throw a dummy jab towards your face, as you naturally go to block it I step outwards to kick your left knee with my right leg causing your knee to buckle.* (stepping outwards generates momentum and power)
