Yeah, it was Book of the End I was referring to. Looking back, I agree that it wouldn't make sense for him to be able to affect Byakuya's distant past, but since he can insert himself into any point of his victim's life that he wants, he could just change something around that happened within his life span. I'm not so sure that Byakuya's personality or outlook on things would even matter - Shukuro was able to turn a cruel, manipulative ally into a selfless enemy. Unless some kind of definite limit is confirmed on the ability, I'd say that only Kyoka Suigetsu is more broken. Of course, out of all the fights going on, I see Byakuya losing as the least likely conclusion possible. And thinking on it again, Byakuya would be a very boring villain anyway.
