Desaparecer

It feels like a 23 because you can clear it by mashing 4-notes without thinking, but if you hit the on-beats, it can hold its own against 24s.

I think it's a mid-high level, on par with Crankie.

It's manageable since it only comes out in 6-half, making it easy to save stamina.

It's important to fill the gauge where you need to (including the twist runs) and mash properly where you're supposed to mash.
