And I didn't even beat it. That stage is way too hard.
You can basically beat anything with enough glass stacks. The start is a little rough, but after like 3 stacks, it should be very doable. You just have to get Yu to almost the curse node, then quickly switch to Mei to grind powerups. After the first curse node has been cleared, you should have plenty of wiggle room to juggle between getting powerups and refilling Yu's bar between the fast and slow parts of the song.
Also, vending machine powerups help too. Having the one for crits prepared usually helps me out, but if you need more than that you can try rerolling for a better set.
