what a sweet PV, its really cute and fitting to the song. I love the concept of the PV, not only you get to see almost all the member at all time, their interaction to the screen is interesting too.
However, when I look at the drama thingy in the middle I can't help but to be reminded of Amimi's cheesy C grade PV in Hanjuku Girl Sora~Ami Hour. Funny as hell.
the coolest part for me in this PV though, is at 00:02:14. Tachibana, Puni Puni and Yazawa doing wotagei~
epic win~
edit : funny how they didn't put Sakacchi in the same lineup as the OLs and the College girls
