Mental Rider

Whether you're a local or not, if you have no prior knowledge, you can get a 12-second cut. The "Devil's 12 Seconds" is level 17, and while the rest is easier than a high-level 16, patterns that are easy to make small mistakes on keep coming down, so don't let your guard down just because you passed the 12-second mark. Since the BPM of the 12-second section is lower than the subsequent sections, if you go at your usual speed, you're likely to misread, stumble, and lead into a terrible dance, so it's better to preview the sections where the beat breaks. After that, especially the section immediately following the 12 seconds, try not to get a miss even if you get a bad until your gauge is recovered.

Also, the BPM is a bit fast, and there are a lot of twists, and the stamina requirement is somewhat high, but after that, if you can handle the runs until the very end, the battle for this song is over. It might feel like a level 17.

It might be hard for locals to do.

I think it would be mid-to-low even if it were a 17.
