Holy crap, that just knocked my socks off.
The PV is really, really cool. Although the song is quiet, it still gives off a lot of dynamism. Making the bass so quiet was an interesting decision - it was too quiet to catch my attention, but it was laud enough to define chords and assist with the dynamism. Did I mention how cool the pv was? This could possibly be the first vocaloid work I've seen that uses a vibraphone, too.
