STORM

There's definitely the example of Switronic, and if Milk is mid-low, this one also seems to fit mid-low... However, since patterns where runs dominate the board like this are rare up to 14, I wouldn't recommend it to users who just hit 15; I suggest practicing it when you're a mid-level user who wants to raise your skill. Since there are no twists in the runs and they're slow, it's even better if you practice stepping lightly by optimizing your movement as much as possible.

If you've survived Switronic at the same level, you must grit your teeth and learn the runs. In future charts, runs intended to raise the difficulty will start at least at this BPM. Unlike the same-level S21, there are quite a few elements that can ruin your judgment, so stay focused.

Top tier among the previous works. The late-game fast runs (compared to the drills and Switronic) are quite long, making it easy to break off from exhaustion. It feels harder than Switronic but less stamina-draining than Re:End. Around the middle of mid-low.
