It rocked. And without question, it was metal even as it was also catchy and entertaining. Frontwoman Su-Metal has the strut and style of a veteran rocker, a mass of contrasts in a red and black costume that combined ballerina, anime character and rock goddess.

Rocking out to a song about the guilty pleasure of chocolate, chirped by smiling maidens? Yep.
