Speaking of the first Chu invasion, Sei trusts Shin to handle it, over Ousen. I'm sure that in the manga Sei's trust issues for Ousen will be highlighted as a factor in that decision.
Still, Shin being made the supreme commander of the mission that should have brought Chu down...that's really huge. So at this point of the manga, will he already be considered the best (or most accomplished) Qin Six outside of Ousen?
