I didn't either before lvl 20.
This is more a question to the community developer, can we get a drop chance rate on the girls in the bosses squads because I've fought them probably 100 times at this point and have yet to get a girl :'(
Damn, I should restraint myself to roll the great pachinko everytime I have 35K golds...
Now, I have 3 girls max affection waiting for the 45K gold upgrade to rank 3 because I waste monney everytime
It seems like half the time I spend 35k I make it back. Or end up with more than I had before.
