Song Production Information[1][]


This is the first time I've done an instrumental song for pop'n. When I was trying to figure out what to make for a demo, Haya-P told me, "Make something fa~st!", so I made this with only that in mind.

Maybe this isn't as fast as it might be at 150 BPM, but it's fast enough for me. Besides, it's really nice to be able to make a fast song that's almost two minutes long. Next time, I'll try for 180 BPM...

So anyway, the chart for this song was written by "Papehina". He says the EX chart we anticipated (demanded? forced?) had the most notes in a chart he'd ever written, so that's pretty cool.

Let's face today with fighting spirit as well.

The end.
