Can somebody please advise why anybody would do a x10 pachinko in this event, and not save until the next legendary event? I look at that arcade machine it has no legendary girl's?

Thankfully the boss girl drops had increased in this event. It took no real effort gaining the two tanned girls both dropped in 3-4 goes. Although curiously it had caused a nightmare gaining their other normal girls. Unless the normal drops have everything to do with up'ing the harem level and upgrading their stars?
