Here's my riddle, I hope it's all right. I've never written one for FFVI, and the feel of it is a bit different. This'll either be super easy or rather vague and difficult.

I'm one of a kind,
You'll not see my better,
I'm first of my class,
Right down to the letter.

There are others who'll come,
With fancier moves,
But if you stick with me,
Then I'll only improve.
