By SG, you mean Shadow Gallade, right? I think he's still with us, I just haven't heard much from him.
Me, Psycho Cut, and Vandslaux are already going to be division leaders(oh, right, Psycho Cut is also the "main brain", so he's going to run a division and the entire clan, so change 5 co-leaders to 4, that was a mistake). Soperman is up for consideration, though. I already voted for him.
