When I went to pick up BlazBlue at a local gamestop, I planed on maining Jin. He looked like a high ranking military official out to spread justice at any cost. Sort of a badass cop. I played him for quite a bit, but after beating his story and arcade a few times, he didn't really seem like the kind of character I had originally envisioned.
I tried out Arakune and fell in love with his playstyle almost instantly. A sporatic, very mobile character. I still didnt very much enjoy his description though, so he's ended up as my sub. :8/:
While trying out every character, I eventually picked up Hakumen. Everything I was looking for in Jin, with what I would describe as a twitchy and heavy hitting playstyle. His defense is amazing once you get used to his drive, and his offense is equally impressive if you learn how to chain his specials (half a lifebar in a combo:yaaay:). So I've ended up with him as my main.
