The PV is awesome. Fits in well with SDN's style, a little retro, but managed to be super sexy while not too raunchy. Cindy wowed me with her hotness. I didn't think she could pull it off so well.
Yukari and Meetan also did great.
Serina was also pretty nice, the rest were too. The song is still a little... DDRish, but the PV does make me like it a bit more. Awesome stuff!
