Eto has a sadistic personality, often expressing joy at the expense of others' suffering. She has no qualms about remorselessly slaughtering humans and ghouls alike, and shows happiness when inflicting pain on others. Like her mother, Eto has a very sharp intuition about the feelings and desires of people, which she exploits to the fullest when dealing with her victims and manipulating others to do her bidding. Like many ghouls, she is able to compartmentalize her ghoul and human alter egos.
