After her parents were murdered by human traffickers, Mikasa was rescued by Eren Yeager and lived with him and his parents, Grisha and Carla, before the fall of Wall Maria. She is the last descendant of the Shogun clan that stayed on Paradis Island, thereby related to the Azumabito family, and holds significant political power in Hizur.
 
Stoic, loyal, and deadly. Mikasa rarely shows emotion, even around people that she cares about. She seems to have dedicated her whole life to protecting Eren, perhaps in return for saving her when she was a child.
