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 where they have died. Mikasa is emotionally withdrawn and sometimes is noticeably dangerous, intimidating her enemies or even comrades. She is quite stoic and level headed, rarely seen to lose her cool or be at a loss of what to do, no matter how bleak the situation seems to be. Her will is also remarkably strong.
