The hand gestures between Onokatsu and Shishi were a little weird, right? And is that "bounce" that Shishi was doing at the start kinda uncommon? Maybe I'm reading into it, but it seemed like the officials' expressions were even more grim at the end. I wonder if he got a talking-to at the end of the day. Well, Shishi's in the tourney leader group with 4-1 tho.
Shishi definitely has a unique way of setting up before the tachiai. Not sure if it's against any rules but of course the sumo board doesn't generally like anything new.
