Well to be totally honest I'm not too thrilled with the covers, I think the straight-forward cute covers they have been doing are just fine, but with this type of covers they'll be perceived even less as an idol group. Hopefully it's just a one-time deal due to the anime tie-in.
I expected Kaoru not be included in this single since she's still back home under house-arrest, I'm beginning to feel that they are just delaying the inevitable of her leaving the group due to some kind of contractual situation either with FujiTV or her own agency. It's too bad if that happens but this group had to deal with premature departures before with #10 and #18, so I guess that's nothing new really.
Yeah I can't wait for the PV, it will have quite an impact for better or worse.
