Sanada didn't even use SoSA against Atobe, but the results probably would have been the same. I still rank Atobe higher than Sanada, as for Shiraishi, he is around their level, if not ever so slightly lower because he doesn't have many special moves. Fuji is better than Shiraishi with his new moves, he just spammed Gatekeeper of the Hekatoncheires, he didn't even change it up until the last hit. It was like when Ryoma faced Fuji and he spammed Higumo Otoshi, course he told Ryoma to try and break it, I think this was sort of the same thing. I was probably more of a test than anything, to see how good the Gatekeeper of the Hekatoncheires really was. If he changed it up, I bet he would have beaten him, not giving Shiraishi the chance to become to familiar with any of the counters.
I think Renji will have improved about as much as Inui, but Kirihara is probably on par with Shiraishi, considering he has SoSA and has improved normally. I can almost bet on it that Kirihara is better than Renji now, and could beat Sanada if he uses SoSA and Sanada doesn't. But the ordering for Rik vs. Sek will be messed up now it seems. Tezuka or Ryoma v Yukimaru, Sanada v Fuji, but what about the other matches?
I just think it like it is.
