I get the frustration but on the other hand they did really well coming into this tournament. Even though I for one doubted them after the match with China but eventually they proved everyone wrong.
I still think the liberos could be better, neither did it for me personally. Manabe wants to make Uchiseto happen so bad but she's just not it. Sato was also terrible all through out. They should also rethink Airi's role and maybe amplify it.
Next stage for Koga should be an overseas experience.
