No, they don't. It's a standard medal-count event again, with a minimum of 7 medals to get the girl (lvl 1, no skills/equipment) upto 24 medals for the lvl 30 girl with everything unlocked.

In the campaign screen on the Special tab, click on the event bar (the one with the pretty graphics) instead of the bar that takes you directly to the phase. On the advertisement screen you should get, click on "Event Details" in the top right.
