Another IV/IX fan, hooray! Anyway, stamping. I did see some Soldier, but overall, as the rest have already said, I'm going to go with Thief. They're generally the kind of people you'd want as a friend, and they tend to have a pretty good sense of humour - or at least are good-natured enough to take a joke. As people have already mentioned, the more-introverted side of you fits very well with Ninja - and quite a few Thieves/Ninjas have a bit of a tendency to boast. (I thought of Edge when you said that in your application, actually, so...)
