Legitimately, she will be the last one because she can't be an idol anywhere else.
Gura has had one foot out the door for 3 years now and frankly, might be the next one to go depending on how the Ame graduation goes. She knows she can coast and Cover will never do anything to her because she's THE biggest sub number and therefore a mascot.
Ina, I honestly wouldn't be surprised to see her go soon either. In a recent stream, she basically said how she was able to balance her work, gaming, and social life before joining Holo because she didn't have a social life, but now between Holo, her priestess duties, and being in Japan where she has a social life with other Holo talents, she's finding it harder to balance everything. She's not going to give up her priestess duties, and she wants to be a functioning adult with a social life, so that kind of leaves Holo as the breaking point.
Mori is probably the last before Kiara to go, but I think if her roommate got a decent musical career offer, she might hit the door instead of letting Cover keep taking a cut of her money for her music.
