Note that even with that setup, you will need a lot of tries and luck on skill activation/crit and evasion. I tried the two stages to be sure and I loose on lack of luck. Even with full rainbow team and maw everything, thoses monsters are able to oneshot every girl (even Kerria with ampies, lvl85 and +105% DEF).

And I didn't put that much effort don't worry. I wanred to present this squad for a while. It was the perfect occasion
