I was going to ask the same thing in regards to the back dancers.
Hikaru has really improved dance-wise!! There's times where she's very awkward or seems like she's not sure how to place herself or where she should be or whatever but overall she's doing so well.
As a Miya fan though, I have to be honest - I'm surpised by her but in a slightly negative way. In Berryz, she kicked ass vocally, it was rare to hear her sound off or out of shape, and her dancing was decent especially in dance shots or important performances where she'd kick it up a notch and not let herself get too slacky about the moves. Now though, she's really slacking in both areas - she's sounded pretty rough to me in all of Pink's recent performances, like the Love Candy one... especially when comparing her to her Berryz and Buono! days. I can't be the only one noticing? I mean, Miya's energy in dancing slowly declined over the years and so I'm used to her not being as energetic as she used to be (like pre-2012) but I feel like now she's barely dancing half the time and almost doesn't seem like she cares to be there. Like in their recent Malaysia concert footage, during Kirei Kawaii Mirai it was really noticeable.
I'm not saying this to hate on Miya, 'cause I love her as much as the next Miya-fan (she got me into H!P in the first place with Buono!), but I'm just worried because she doesn't seem like herself performance level-wise lately. Maybe I'm the only one feeling this way.
