max level them first , then u need lvl 2 or 3 on yuyu because u need her skill at a certain point.

Also u need to place yuyu 1 or 2 up earlier , so awakening yuyu , or having an awakened jerome will help.

The difference between yuyu and belinda is that belinda can deploy her skill faster because shes a plat...o u kinda need to compensate by placing yuyu earlier
