Floor 24 f2p
Floor 24 cleared without much SSR characters, momo and yaga is used to buff yuji (watch Ur ce usage), momo's recollection bit with her evade skills can help reducing a lot of damage, stack Yuki's shield 3 times before taking the ult damage, and you should be able to finish the boss before your team dies, I hope this helped those stucked on this floor.
