Thread: Drop Rate for Girls

I started playing a few days ago and I've fought the World 2 Boss (Dark Lord) over 50 times but have yet to get any of the girls from his harem as a drop. Is there anyway to increase the drop rate since it's going to take weeks to get the 3 girls from a single world boss at this rate.

Also, is there any way to set cash collections from the girls to be automatic?

Thanks
