So what you mean is that you want to be the first Justice ranger since when you started. I think that's quite different than being the first Justice ranger period.
In your credit, though, I will say that when Maui was a Justice ranger, the Justice cabal just started, so of course it was a lot easier to get in. Also, he eventually quit Justice because he didn't feel like it anymore (chasing down criminals, etc.) instead of, say, living a normal Justice life (whatever that means). So...perhaps...I don't know...you could aspire to be the first really good Justice ranger?
