Rikku fans scare me. She's like what, 14? shiver. Personally out of FF-X, Lulu is more my style - she's dark, she's got that smouldering look, we won't even talk about the rack - Girls like that are demons. But in a good way.
After that... probably Tifa because I like her attitude. Unlike most FF heroines she can definately take care of herself
Finally I would probably toss in a vote for Rinoa. She's against my type basically, but she's the glue that keeps everyone together. You have to admire that in someone.
Ok, I just realized what I typed and now I am terribly ashamed at myself. Time to go look at real girls now ><
