Hm...This is a tricky one, eh? Because that was the best idea I had towards resolving this issue.
Well, there's always a Senate kinda thing I suppose, with Canus, Yumemi, and the like.
Canus gets to keep a position of relative power, while Yumemi also gets the same. And if Canus tries anything, there's gonna be more folks to block him. Same goes for the others.
