Multiple Kerrias would do it for sure, and quickly, if somebody ran them.

Don't know about DMM, but Kerria is the best flower knight that exists here in my opinion. Now we know why Alpinia got counter, dodge and absorbs HP on Kerria is OP and we don't get two of them.

This boss gives Saffron a beat down like shes a 2*

Others that have this combo and can survive are 5* and while very good, cant match the damage queen Kerria puts out
