But people have talked about her being promoted ever since she was revealed as a research student. She's popular from before joining, so it's only a matter of time.
The things Nacchan and Yonechan did have taken place over a long period of time - 4 years for Yonechan at least - so ...well, all I want to say is I don't want people to attack Kaworu if she's promoted in any team (whenever that is really).
Just like when Yui joined Team K and took over Erepyon's position, and Shihorin took over Maachan's position in Team B, and so on since the group got formed. Kaworu should be judged on who she is, what she does, and only on that, and not bring in conspiracy theories and such
Please don't direct any frustration at Kaoru kuz of this scandal. Not just her but the girls who are to take those empty spots.
I don't believe she will be promoted that fast. She hasn't performed a stage yet, and the 6th anniversary don't count.
