Although Sango's body was sent flying away abrasively, he was able to prevent himself from falling into an awkward position by having his palm on the ground to steady his body.
When he stopped, he ended up in a posture where he had his five right fingers steeled to the ground and the claw marks that showed how he had slid to where he was now.
As for his body, they were bent down in a kneeling position while he had his head faced to the front, toward Kian.
"I don't know what you are talking about". Sango replied, getting himself up and dusting away the ground particles that had gathered on his body when he had fallen.
"Don't feign ignorance Sango. I can feel it, your body movement and the way you respond to attacks. It is almost as if you have no control over your own body. What explanation can there be for that except you pulling back on your punches".
