OMG that's one of those things that's so obvious/good I can't believe it didn't enter out conversation earlier
By process of elimination, if there is a secret weapon, it has to be Hayashinnabe at OP. It's the only thing we haven't seen.
I just hope Nagaoka is up to it. I haven't seen Hayashinnabe hit a ball from the right side of the court in years. I think it bums out Kurogo to be stationed there, although she does play that position with Toray. I think she's much better from the left
i stopped worrying for nagaoka she just does her thing. but it would be bad if kurogo wasn't effective on that side since nagaoka will never be a starter so if they have other options they should test it out already especially hayashi.
