All I have to say about Kisenosato is I didn't support him initially, I disagree with some of the things he's said, I think he has a spotty record which points in both directions, but now that he's yokozuna, I support him as an American and hope he does well.
Hakuho really has it out for Tochiozan, he had that "really? it was that easy" look today, and that cat clapping thing a while back, and just overall screwing with him.
Mitakeumi and Ikioi avoid touching the belt almost all the time, but don't really push-and-thrust, or at least don't actively seek it. A strange middle ground, where evidently Shodai and Hakuho don't want to be.
