yes kikuri require a insane amount of BC for her SBB, mariudeth 6* SBB its only 3 hits so you not gonna get many BCs out of that.

best option if you want to do unlimited SBB would be zellha instead of kikuri or of course SGX instead of mariudeth and another wather unit of your choice,

be sure you use a friend that boost BB gauge Felneus Uda Dia are great because their SBB boost BC drop rates, if you face 1-2 enemies use the BC+ drop skill first
