OH MY GOODNESS! That guy doing the dance with them in RR21 is Hyadain, AKA Maeyamada Kenichi, who writes a lot of the music for Momoiro Clover Z, Shiritsu Ebishu Chuugaku, Aso Natsuko and his own solo stuff. I'm a big fan of his, so it'll be fun to see the full clip!!
And it will be fun to see ABCHO on Happy Music; we know that both Kashiwagi Yuki and Watanabe Miyuki (of NMB but in Manatsu no Sounds Good) are huge fans of Rika's, so I hope they play that up!
Excited for this single! I love Me wo Tojitte Gyushiyo and Kuusou Discotheque sounds excellent. Very glad I preordered the LE!!
