Nightwatch: Closer

Today is the first time you're on nightwatch, still a stranger to everything.
In a dark, quiet little post, you feel something strange.
Is it because of your first time? Or is there really something here?
The senior who came with you fell asleep before you knew it, and you are the only one who is awake in this narrow space...

You have to hold out until the shift worker comes by preventing threatening anomalies.
Anomalies appear randomly under the influence of factors such as mental level, noise level, brightness of the room, and time.
Try everything you can: shine a flashlight, look carefully, interrogation, approach, run away.
If you keep your head straight, there's no anomalies that you can't stop.
