^I was mostly wondering specifically what they cut, if anything besides her talking. Her chatting, then walking off stage to change into that outfit is a bit of an odd unexciting way to do a costume change, which would be very unlike Kuu. Some of the Extra footage shows Kuu coming out in that last outfit and everyone surprising her for her birthday singing Birthday Eve with that giant cake. However, there's even a bit missing in-between that.
EDIT: Oh, and check this out. I Kumi-fied my phone using one of those First Press stickers that came with the Kingdom album. Don't worry, I got an extra one of this same sticker.
What you all think?
