Luna is the strange girl in Ravenclaw. Ginny is the quidditch-champion in Gryffindor. Sure Luna and Ginny know who eachother are, mutual aquantinces some might say, plus they're both in fifth year. But that's where it stops...well it should've stopped there ;) [AUTHOR'S NOTE: I'm using the personality of Book Ginny because they ripped her off in the movies also I'm just having fun with is so please don't judge. I know in the books Ginny and Luna are super great friends but I'm starting them off as just like aqquantences]
