I don't know if I need a spoiler for this, but the two-handed heart gesture the girls made during the OP dance is a signature move for Morning Musume
, requently made by two of the "cute" members, Michishige Sayum
i and Kusumi Koharu
. The gesture is also part of Kusumi Koharu's PV dance for "Balalaika", the OP of the extremely popular young girl's anime, "Kirarin Revolution
I guess everyone knows that KyoAni OP/ED dances are parodies of Hello! Project
groups, right? I was playing the 2006 Momusu concert as I was building my home gym last night and boy, I would guess that the great majority of the Wotas at the concert probably watched both Haruhi and Lucky Star. There's must be a huge overlap between idoru otaku and anime otaku.
