I feel like if there's some sort of impending graduations that are being held back due to a financial report it'd be a "wave" (where we get a list of names and dates set out anywhere from 1-3 months from now) of them like ex-ID/KR. Which- in my opinion would be more damaging PR-wise (what little is left, anyway) than just letting them trickle out like normal.
It'd be really bad For NijiEN if Vivi and Kunai graduate because that's literally 2 people out of a 3 person wave that recently debuted leaving.
