It really does seem that it won't be a continuation of MGI and II, seeing as how Kuumin AKA Dance is there in MG3, its likely that Kuumin's role there isn't as Dance, but as someone new, so likely, there will be a possibility that the other members will appear, just that in a newer role and less prominent then the the first two. I was kind of hoping for a continuation when the theme wasn't said, but after knowing the theme being a
'prison' I gave up with the thought of it being a continuation. It's good, MGIII, it seems interesting, I'll still watch this, seems like its gonna be entertaining, especially with it being in a prison, how the
'school' part will happen, I want to know too though...unless they give me a plot route that entitles the prisons to place the girls into Majisuka Gakuen for correction purpose, then okay...
