Now I can say with to much detail can also confuse someone and that's just going off real life so that could be the same in the rp I would expect.
GodItachi looking at his sensei waving him over. Starting on his left foot he burst towards his sensei. Scared; he wouldnt be at all. He is an Uchiha and has a strong chakra at the same time so this could be even fight for them both but then again he doesnt have the full sharingan developed at this moment. His hands are dragging behind him as he makes his way towards his sensei. Once getting into range of he can punch his sensei he bring his right hand forward with the momentum this would be fast and strong behind the punch.
