The Female Titan arc
Petra is introduced as a member of Squad Levi. She later participates to the expedition outside the Walls where she is killed while battling the Female Titan.

While the Survey Corps go back to Karanes District, Mr. Ral approaches Levi to discuss with him about a letter his daughter sent him. Mr. Ral speaks of Petra's wish to devote herself to Levi and puts the emphasis on his own worry as a father.
