Eren was born to Carla and Grisha Yeager in Shiganshina District within the southern region of Wall Maria. He grew up in the town with his parents and foster sister Mikasa, who moved in with the Yeagers as a child. Eren spent most of his time with Mikasa and their mutual best friend Armin Arlert, whom the pair often defended from neighborhood bullies. Eren is a passionate, determined, hardheaded, and impulsive young man. When they were children, Armin showed him a book depicting the wonders of the outside world. Eren grew to share Armin's curiosity of the world beyond the Walls and resolved to see it for himself. This dream inspired his admiration of the Survey Corps and his desire to join their ranks as soon as he became eligible for enrollment. When the Titans suddenly broke through Wall Maria into Shiganshina, Eren was forced to watch on as his mother became trapped under the rubble of their house and eaten by a titan. Forever changed from this event, Eren vows to kill every last titan.
