That where double khobans would come to play, during that event ya get double the amount, so if ya get 75 khobans, you get 175 instead as example, an same with cash!
I mean one week of double the money as an experimental idea, then if it does good once a month, an have event that let ya get all ladies ya dont have, an finish various stuff ya missed!!
Do you want the ladies in your harem to become a single one an when ya get new after maximizing their level an stats, they join into the merged one, what ya think?
It means say ya did not finish a past event ya get chance to finish them or event ya missed before ya played game, or say ya want a certain female an such in event or pachinko ya would get better chance at that by having it all as one!
