I think the only appropriate response to the passion that is rock would be:
Rock on, Death Devil.
The other thing I forgot to mention is Ho-kago stalkers.
@sunwen: yes, Yui led Sawa-chan astray big time. It was all a setup, just as how that the cake is a lie.
Seriously though, if anyone is going to make Sawako act, it'd be Yui. With her cavalier attitudes running completely against the image and the notorious name of Death Devil, made worse with her bumbling antics on-stage, Sawa-chan is doomed to face the music.
