Miku sounds pretty nice in the song here--it's interesting hearing older Vocaloid songs, Miku really does have a sort of robotic sound that is very enjoyable. Very 'classic Vocaloid' sound, if that makes sense? As for the music video itself, it's nice. It's short and cute enough. Magical girl fans may get a kick out of it. It's basically all the juicy parts of a magical girl show--the mascot, the transformation, the battle, the dance sequence--crammed into its own little no-context plot-minimal space, like watching an AMV for a magical girl show you've never seen. For people who don't care for the magical girl genre, itdoesn't have much else to offer. The animation is a bit stiff at times, specifically in the dance sections, but it is far above the bar if the standard is 'Vocaloid Music Video circa 2013'. The times it remembers it is a makeup commercial pass by reasonably painlessly, though some bits have framing that makes it hard not to go 'oh right, this is an ad'.
