Wait, HOW? You literally get introduced to her in an unavoidable cutscene at one point, she's the naked lady with long purple hair in the Recollection Room XD Granted that time she mostly explains and teases about what her true role is, but after that you gotta actively seek her out: Every time you go into the rec. room at night, you have to go to the small building on the left side of the area, Administrator will be sitting there and if you talk to her she will give you clues about the overall story/future and reveal how she has been the main culprit behind a lot of shit.
