i dont know if its bad, but Ishii should still be a starter, Mayu seems tensed and she just cant pass through the block. While Ishii did well on the 3rd Set.
They should try to put back Kurogo as an open hitter and have Nagaoka as a starter. Miyu's slowly getting back from where she left off before her injury and I think thats a great sign for Japan.
Koga played well too, I have seen her talk during one of the time-outs, she's like calling the shots for the team and that's good for her, that was Saori's role a couple of years back.
Hayashi too, her aura made me think she was Risa ☺️☺️
