Last day of the event and I finally finished with 24 stars. Been farming for Lauren for 15+ runs already in Fierce Island Battle and so far got none. Strange since I got him pretty easily before but I used up all 3 Laurens to CC Spica. Guess they spam drop him for a short while and then make him scarce or I was just lucky to have gotten him 3 times. And Alissa never seems to drop anymore after getting her once in Fire Fight.
