Windmill

I cleared this even back when I was an 11-level player.

I don't think it's quite low-level, but since it has a lot of simple drills, I think it's a song you can clear quickly as long as you have the stamina. Since there are more complex drill songs like Violet Perfume, it's a bit hard to see this as a standard 13.

Because of the speed itself, it's not a low-level chart for locals.
