I watched some parts, and I gotta say two things:
Spoiler:
1) WHY HASN'T SHE RELEASED BRING IT ON ALREADY???
It was the best part of the encore for me, hands down. Also, while watching it, I though of a PV in which Kuu was dressed like a cheerleader, and it happened to me... Has she already shot a PV in a cheerleader outfit? I think there was a CM, but not a PV...
2) That medley on the second block was FUCKING AWESOME, but Crazy 4 U and TABOO were so damn short
