I think v7.3 changed this boss | SSS Rimestar 47856 (39880) | SS0 FV / SS0 HTr / SSS CN / 4* Kiana
I did this run before https://youtu.be/40FRsxPseuM but I honestly think something changed in v7.3 that made the old way actually impossible.
In this run Ai does things slightly differently from last time that makes the score possible again.
At 0:33 while Bronya is shooting her gun, hold down + left or down + right depending on the camera angle while mashing ult to turn Bronya around before she transforms. This will make Ai's QTE backflip move her closer to Rimestar. After her QTE use one basic attack to turn her around to face Rimestar, then do evasion without any direction to perform a backflip to parry all three chakrams. Fu Hua's punch combo should start while the timer is still at 4:58. Remember to hold a direction (any direction) when she is coming down from the uppercut while mashing ult; this should make the ult come out earlier. The ult should be right after the timer changes to 4:56.
I highly recommend picking up the HP pack first before doing Bronya's combo and ult at 1:09, it will make things easier because it will be one less item for Ai to pick up later. After Ai's QTE at 1:20, do one evasion followed by one basic attack and ult immediately after the 3rd ping. It is possible to go slightly too fast and Ai will ult while Rimestar is still invulnerable and the run will fail, but if the ult hits then it should be a guaranteed win. Fu Hua's parry attack should be able to hit while the clock is still at 4:53.
