Fay Yeager

Grisha's sister. She is the paternal aunt of Zeke and Eren. At the age of 8, she went out with Grisha and, after witnessing an airship, they left the internment zone, where they encountered Marleyan authorities Kruger and Gross. While Grisha was receiving punishment for both of them from Kruger, she was taken away by Gross, who told her to go home. Later, she was found dead by the river the next day instead of returning home.

Subsequently, the truth was revealed to Grisha by Grice of the Eldian Restorationists, uncovering that she was actually attacked and devoured by Gross's sons' pet dogs. Upon learning the truth, Grisha began to act as a member of the Restorationists.
