Mayu will be fine people….She learns, makes adaptations. Japan is in its first year with Manabe (yes second go around), Mayu has never been the focus of a team’s offense and nor should she be. She’s learning how he wants to play and what needs have to be met.
Hayashi hasn’t really set the world on fire either, let alone any one else in the last OH/OPP spot. Hayashi is basically the other big OH for JT Marvelous after Drews (now gone).
