under Currency, you can see how much BCs you get for the girls.
and under Wares, you find the stuff you can buy with BCs and how much they are (if nutaku don't change anything).

i have to say, that i don't use my FGs for the gachas anymore, the chances are too low. if you don't spend NG you should probably collect FGs for gacha.

thanks for the information

seeing as I don't get much 4* and higher, and that 3* are not uncommon at all, I think I will try the gacha
