Binary star

It starts off calm and then goes wild at the end, a clear build-up. Huff puff

It's a crossover but it's not a crossover, what is this? / It's a stamina chart.

Watch out, the run at the beginning drains your stamina like crazy. Also, for the second half, I found it easier to hit if I played with the mindset of extending my legs more than I thought.

It features twist elements that my body rejects and a dense run style. You might feel a bit of resistance toward the late spike starting at 1:33 in the official video, but since you can build up 50 combos each on the red hold and the single-note section before entering, I don't think it has a huge impact on clearing once you actually try it.

If you conserve stamina, you're fine. The ending is confusing but all in all a good chart. Conflict and Gargoyle are good prerequisites for this imo.
