Anya is Lisa's pen pal in another country.
She sends Lisa a letter about how the president of her country was overthrown and replaced by General Krull. However, as Lisa reads, Anya's replaced by a man (heavily implied to either be one of Krull's henchmen or Krull himself) who praises the "benevolent" general. The letter was signed "little girl" instead of her name. It is probable that it is because the other writer did not bother to find out her name.
