Yoruichi noticed her opponent's movement forward so she parts her arms from being crossed, Mashiro's left hand starts the fight by bolting forward, she simply leans back quickly so that the jab was out of reach of her face. From her left side she could see the right hook coming around, and so by countering stepped back with her right whilst also crossing it behind her left simultaneously raising her right hand up and twisting her body so that it flanks Mashiro's wrist and grabs onto it. She moves swiftly to the left by stepping with the respective foot to the side of her adversary keeping a tight grip on the wrist placing her left palm on the elbow of her opponent, and then shoots out her arm so that it straightens out Mashiro's, applying enough pressure this would cause pain on the joint. Yoruichi circles around Mashiro whilst holding her arm in this position, now being slightly to the right behind her. She didn't apply too much force as to break the arm, her adversary dropping a level was turned against her when Yoruichi claimed the arm and kept her crouched like this using the pain in her arm.
