Ah, someone beat me to it. Oh well, there's plenty more spoilers to go around, even if text only.
Spoiler for Spoilers:
-Apparently Funaq and Sera are talking about how Usuzan's 4th and 5th players are the only ones who are really nationals-tier. So yeah, Usuzan is indeed side B's Shindouji, but without the awesome and bro as hell vanguard.
-The red head apparently named Shishihara Sawaya. It's a pity about the not-national tier thing, guess Mako won't be seeing much action till the finals.
-The confirmation sentinel is talking about comes from the fact Sawaya actually quotes the bible. Won't get stronger evidence than that.
-The Kuro look-alike is apparently called Maya Yukiko. Fun fact: She's a 1st year.
-And here's Rinkai's choice to tear Mako a new one.
