Iemitsu continues its barrage of PC-98 vocal arranges with this; Dream Express, Mystic Square's first ever stage theme. There's only one word to describe this song:

LOLI-TASTIC.

It really does sound like Night Lights, as you can see...or rather, hear. Dream Express is a considerably good theme despite being made fit for Stage 1. Well, no one can blame ZUN for putting such BGM in such a position, as it DOES PLUG A HOLE in Mystic Square's opening; from a mellow, fun-filled adventure to a dramatic and epic fight in the depths.
