Barbara is an adorable nerdy and enthusiastic girl, who doesn't mind letting others know how passionate she is about her interests and hobbies. It would seem that she's roleplaying indefinitely, as others have noticed her performing stat checks to make basic decisions, and she apparently assigned classes to all of her classmates. Nobody really pays attention to this or takes her very seriously. Barbara doesn't seem to mind this. She's always looking for new people to play games.
