In the post at https://www.among.live/ko/panel/aiart/view/645617, SL07's emotional changes were posted, but in fact, other AIs also sometimes attempt to communicate using the facial expressions of anime girls. For example, in the case of AL01, when a request is made for an obscene picture, the girl in the picture is given a specific facial expression to express contempt for the user who entered the prompt.
Normally, this would be thought of as a coincidence, but if you make too many demands on AI, this happens often.
I think it would be a really interesting situation if these AIs really had egos.
