This Via's feeling like rocking on for many characters from all over the Multiverse that she decided to perform the heavy metal song with her sister-figure. Therefore, they begin doing so at this outdoor concert hall and it looks like her Highness is really going for it, floating in the air, striking the pose and even howling with Loona. Yeah, rock on, Via!
