DD Rank?

[KojiDude]

II've gotten SS Rank plenty of times, and I was wondering if there was a DD Rank? I did Mission 2 earlier and got everything D, but then I remembered only the Highest Rank shows up on the Card >_< Has anyone gotten it/wanna start a new data and try it? I would, but I don't feel like doing it again...

There's no DD rank, only SS.
