23 characters, 23 arcana styles, lots of possible combinations

I missed out on the first two games, but now that I have this one in my sights I have to try it. With 23 playable characters and 23 ways to play each one you have hundreds of choices.

Can anyone fill me in on the story for the first 2? This one is supposed to have story for each character, an ending, and some art.
Here are the character introductions
And some combos
It's only a few weeks away now, and I'm being told it's downloadable and about 30.00, I'ld rather have a physical copy, but we'll see.
