The Rall family (ラル家 Raru-ke?) is one of several families that live within the Walls. It is the family where Petra Rall of the Special Operation Squad hailed from.
Petra Rall is first introduced as a member of the Levi Squad.
She later participates in the 57th expedition outside the Walls where she is killed while battling the Female Titan.
When the Scout Regiment return to Calaneth District, Mr. Rall approaches Captain Levi to discuss with him about a letter his daughter sent him. Mr. Rall speaks of Petra's wish to devote herself to Levi and puts the emphasis on his own worry as a father.
