Jill, Yiji-chan, Min, Aly, K, Tsubaki-chan and Kate do AWESOME cosplay at Waicon 07, and an AWESOMELY entertaining skit to boot. Regardless to say but for those who weren't there and don't know these kids, they won best performance ;]
Only like 2 minutes of this video are of the skit xD but the questions afterwards are awesome too.
