i'm stuck on the mission "Bring Icas to Me". Not too sure how to do this. I know i'm suppose to get "a bunch of pretty girls" but the only people I can currently get in my party are marica and those two girls that act as an Sup slot in my party and I can only add one of them. Accepted this quest before going to attack the place Cougar came from. Read several gamefaq's walkthroughs and they said something about doing it after a castle upgrade? When is that?
