A young girl who can read minds, Anya is the only one who knows the overall situation of her family but conceals her talents and her awareness, both out of excitement over Loid's and Yor's jobs and for fear of abandonment. She claimed to be six when she read Loid’s mind and learned that he needed a six-year-old for his mission, although she appears to be around age four or five. Her true age is currently unknown. She was originally an experimental human test subject dubbed "Subject 007" (被検体007, Hikentai Zero Zero Nana, lit. "Test Subject 007"). The only confirmed details of her past is her name "Anya" and that she had been adopted by several families, only to be returned to the orphanages each time. Due to her ability Anya is not good with crowds, and because Anya has not received a proper education she is not good at studying. She tends to read other peoples' minds for test answers. However, she cannot use her psionic ability during a new moon. Anya's favorite food is peanuts, she likes the spy-themed cartoon Spy Wars, and thinks anything involving "secrets" and "missions" are exciting. She is really flexible and quick-witted for a child her age, and from time to time she is able to trick Loid. She also appears to have talent in Classic Literature.
