The Addendum in the Wisdom Rotary description adds some ambiguity to whether it's answering Hara's quesion at all. We can probably be sure it's being accurate that Azu will die in one year.I think that actually answer the question
On assumption, what the phone is telling is a truth.
It could mean she will realize in one year later that she has to let Anzu die to return normal.
Or, if SIA knew they had to be taken down after they became more powerful in one year.
As it is, SIA seems barely have reason to kill them from understaffing.
