So... Prior to SV (unless she's not in that outside of DLC either) or SK2, was Daidouji kind of pointless, or is it just me?
As far as the games go (basically just Burst), I'm not sure why she exists, really. All you really have is a "legendary" senior who refuses to graduate, is really strong, and that's it. At least the Suzune being Rin makes sense, even though they didn't do anything with that either.
Also, I'm talking only Burst here, to clarify, since she was made out to be a big deal, but I can't think of how she really was one in the context of that game.
