One thing I really love about this song is that everyone gets utilized. All 4 girls sound beautiful in this song. The verses were distributed well, although the group vocals in the refrains are dominated by Riyu to the point where I color-coded them as her. In concerts they sing the lines more in unison than this version, where the refrains are more like Riyu + BeForU .

The song itself is great, though. The lyrics are actually a group effort this time, credited to BeForU and not just Riyu. They did a good job of writing it, too (though I must admit this one was tough for me to translate!).

This album version is a definite improvement vocally from the original DDR version (and also much better than the new version that was on the KI-SE-KI single). I'd recommend anyone to listen to this version over either of those.

Overall, Firefly, especially this album version, is a great group song!
