Desaparecer

The run density is substantial. Since runs at a speed that's hard to maintain pour down, you need to manage your stamina well. In terms of technique, it's easier than Vanish 17, but the song length eats that up.. Therefore, it seems to be on the easier side among the mid-highs, and separately, the gimmicks have no effect on clearing.

The half-twist section = danger zone. It's difficult, but not top-tier. The song is long, so you need to manage your stamina.

Depending on whether you can mash through the Sarabande run or not, the clear difficulty varies significantly. The run is very easy to twist your feet on, so you need to hit it accurately at least a few times to increase your clear chances. Be careful with the holds; if you play them loosely because your stamina is low, your gauge will vanish instantly. While the difficult sections are specific, they aren't short, so it's a song that surprisingly requires stamina.
