Outside of Sayuri skipping a hefty rock across a lake to bludgeon someone, I'm surprised how tame things have been since Rina's episode. I was really expecting Mai's backstory and episode to be wilder but there's still the resolution for her trauma affecting her bowling.
I wonder if this is going to be the catalyst that leads Mai and co. demanding that they solve the issue through bowling rather than bloodshed, resulting in a match between the bowling club and their ancestors. Though, we don't know much about how well Anzu or Suguri can bowl.
