It's mine, too! I absolutely love the series, it's a shame it's not more popular.
In order, Raven was my first...kinda. I was playing the game on hard, so when I got to the final dungeon, I actually managed to start and finish a new game on normal and marry Karina (lol, no idea why I said Evelyn, I guess it's been a while :P) before beating the final dungeon on hard. I married Pia third, though I don't know why it took me so long, since I really enjoy her character! (And her hate for squid)
