After her biological parents were murdered by human traffickers, she was rescued by Eren and lived with him and his mother and father for approximately a year before the fall of Wall Maria.

Mikasa's bond with Eren is undoubtedly her most important relationship, and one that defines Mikasa. For Eren's sake, Mikasa has expressed a variety of emotions such as compassion, anger, embarrassment, sadness and tenderness. She has openly wept tears of relief at his safety, and developed vengeful grudges towards those who harm him. asa blushed when it was insinuated she and Eren were lovers, and has suffered crippling distress at the thought of losing Eren forever. Mikasa also wears the red scarf Eren gave her when they first met, holding on to it as a source of strength and comfort when she is upset. [From Shingeki no Kyojin Wiki]
