On April 1st, 2024, Matara announced her podcast with Mint Fantome. By the end of that month, Matara mentioned having met her "rosie friend" during her trip to Japan.
As everyone knows, Mint had already signed with VShojo at this point, so she scouted fellow idol lover Phoebe and a third, undisclosed member. However, considering how Niji members were being poached by VShojo at the time, we can try to pinpoint who it is based on evidence. And that evidence is right here, in LK-san's message:
>>86515618
>>As we're nearing the end of the year, there are two more graduations planned: one in October, one in November.
>>As for the graduations per se: one of them won't really be surprising at all while the other one might shock even those who aren't fans of the branch anymore. You'll be hearing about one of them really soon.
We already know October's graduation was Vivi's (announced October 24th), and it wasn't surprising at all considering the writing was on the wall. However, no graduations were announced in November 2024.
From this, we can infer that it was likely canceled or postponed at the liver's request, especially since the VShojo idol group project wasn't going anywhere. Graduations need to be decided a few months in advance for arrangements to be made, including the announcement date and the effective graduation date. However, these can be canceled or postponed if both parties agree to extend the contract.
Now, what about... let's say, Rosemi? In her case, a graduation announcement at the end of November 2024 would have fit perfectly, as she would have graduated after MCing and hosting the NijiTekken 8 Tournament on December 6th, 2024:

Not to mention, she wasn't giving any signs of leaving ("Neversemi Leavinglock", amirite?), so that, combined with the fact that she's loved both inside and outside of NijiEN, would have made for a truly shocking graduation.
We also have another tidbit that confirms LK-san's claims are true enough:
>>There are no graduations planned for December, but things might change depending on certain "circumstances", liabilities if you will.
We now know these "circumstances" and "liabilities" were Twisty and Aster, hinting that management was about to throw one of them to the sharks by December if things didn't calm down behind the scenes—most likely Twisty, after the massive cover-up operation to try to save Aster's ass.
tl;dr:
1. Rosemi was looking to leave Nijisanji as early as April 2024
2. Rosemi was scouted by Mint's idol group and was in talks with Matara Kan around the time Mint signed with VShojo
3. Rosemi would be the only surprising graduation whose schedule would fit the bill in LK-san's post
4. ?????
5. PROFIT
