Shiori is very aware of things going around her and is also very self-aware, probably more than some people give her credit for.
One funny and interesting thing I remember about her when she was still Moe, is when she decided to fuck around with the person that was interviewing her for his show. It was Domoarigathanks, a now irrelevant leech that got popular because he got friendzoned by Fubuki after sending a bunch of akasupas. He was notorious for not doing any research on the subjects he interviewed on his short-lived show. Moe noticed that he only got his information on VTubers from the Virtual YouTuber wiki, so when it was her turn to be interviewed, she edited her own wiki and put some nonsense on there to catch him in the act. He got felted pretty badly when she called him out on how lazy and retarded he is.
In short, she knows and she's not stupid.
