Ditto on the Byakugan
*Renji watches the approach of his adversary and upon the movement of his opponents arms he prepares himself. As Kirito's arm thrusts forwards, Renji drops his, allowing the back of Kirito's palm to pass over his arm before performing a swift upwards jab with his two forefingers, applying a sharp burst of chakra to a point on his opponents arm, causing Kirito's arm to fly upwards and feel a sensation of numbness due to the shock.
Renji then swiftly turns his hips, stepping forwards with his rear right leg and thrusting forwards with his right palm, aimed at his opponents solar plexus. Renji's strike delivers a blunt force of chakra which knocks his opponent backwards and leaves him slightly winded*
