Can't say anything about Es, since we know nothing about her CF story, but Naoto and some other characters talk about BE stuff without explaining it. So, if this game won't have a short story or some sort of a flashback explaining the novels, it would be necessary to read at least a summary of it to understand what they are talking about in the game. We have this summary on the wiki, look at the pages of BE characters.

Of course, if you want to understand the full story of BlazBlue, then you'll have to read the novels and play XBlaze.
