1) Sanada would show HJnK while playing Fuji.
2) Sanada would show Kuu (his 5th style) while playing Echizen:
"Singles 1: Echizen vs. Sanada
A rematch between these two, with Sanada being serious from the start this time.
Both use the SoSA right off the bat, but Sanada's experience and physical abilities give him access to more techniques so he starts in the lead. Echizen starts mixing in his own shots, including Cool Drive, after which Sanada starts trying his Fuurinkazan styles one after the other, gaining a bit with each until Ryouma finds a way to counter it. It looks like Sanada has shown all his cards and Echizen is in control, but then Sanada unleashes "Grasp like the Void" (I guess that would make it Fuurinkazankuu? Or Kuufuurinkazan? Whatever). Sanada enters a mental state (this is a mental ability as opposed to the other four being physical) where he feels no pressure and has extreme concentration at the same time, which combine to give him a grasp of everything happening in the match. One result is that he starts anticipating Ryouma's moves and uses Tezuka (Sanada) Zone. He also starts placing his shots in Ryouma's blind spots like World of Ice (Void). Ryouma's only answer to this is to reach the Pinnacle of Perfection and win the match."
Remember folks! You heard it here first! Now all Mr. Konomi has to do is have Nagoya win to ruin my day. >_<
By the way, my standing on this is still the same. Nationals Atobe is a better player than Kantou Sanada, but if Rikkaidai beat Nagoya Sanada will be better than Atobe was.
