Supposedly, the title itself is one of Mori's double meanings, where the second meaning is in the way it is pronounced. Like for example, when Hakumen calls himself Jin (Just), the other meaning is that he is Jin.

BlazBlue sounds like BraveBlue (in Japanese), so it would mean that the story not only revolves around the BlazBlue, but also around the Brave of the Blue (in this case, Ragna, while in Bloodedge Experience, it follows Naoto).

Taking into consideration the novels, Celica is the closest to the main heroine, but if only the games, then it would be Nu/Lambda (as a tragic heroine), as the final parts of each game has an important event with her (not to mention that her fate is closely tied with Ragna's). Of course, that's only my opinion.
