Extra Stage theme
"A high-paced theme (?) which is unusual in the Touhou series. It's obvious from the stage that the tempo and enthusiasm are the keys to this song. The tone turns around about 112 degrees in middle of the song which is where Extra really starts (heh)."
This was made after Yukari's stage theme instead of the other way round because this one contains more notes. How are high-paced themes unusual in the Touhou series nowadays, anyway? Even Highly Responsive to Prayers has a bunch of ridiculously fast arpeggios.
