For characters who have established relationships with the locals beforehand, it will be much easier to re-insert themselves back into their old positions over time. The past month has been stressful for everyone (have a look at the updated World Status page for more info) but things are improving as some distance is put between the current date and when the attack occurred, so Kyoko should be able to return to work without too much issue, so long as she doesn't do anything crazy to startle her coworkers. (eg. kicking down a door and violently proclaiming her support for the attack would probably not net her any leading roles.)
