I'd start off with my classpects for the individual Strawhat pirates, but that would end up being like 12 pages of prattling. So I'll just start with the fact that Luffy is the quintessential Lord of Breath if caliborn is anything to go off of for Lord characteristics. Luffy is a character who is ALL about freedom. The freedom to live, the liberation of the oppressed, the freedom of choice, the freedom to dream. He exemplifies change, each and every place he goes to is struck by profound change, and leaves with profound joy (which is arguably one of the minor traits of breath shared with a few other aspects) and he even has his own "felt" in his crew (and the Strawhat Grand Fleet to a lesser extent). If a Lord is a fiercely determined person who despite all odds grips their dream by the testicles and forces it to come true, I could think of nothing better for Luffy. There's a shitload more I could say on him but I'll save that for later hee hee hoo hoo haa haa.
