Kiara guessed right.
When answering the previous question, she had already surmised that some department had taken notice of her abilities and wanted to recruit her.

"I'm personally very fond of a saying, 'What peaceful years we have only exist because someone is carrying the weight in places we can't see.' Our department is just such a place. To ordinary people, we are like characters out of legend, and we might never appear in the public eye in our lifetimes—so the kind of problem you're worried about, not being able to speak well in front of people, doesn't exist."
Many people don't even realize that such a group exists, quietly making sacrifices. Put simply, it's a think tank.
