"There's only so many lives that I actually care about. My enemies made deciding that easy six years ago. So... you're mistaken to seek any compassion from me. Because right now, I'm all out of time and room in my heart to care."

Mikasa Ackerman is one of the two deuteragonists of the series, along with Armin Arlert.

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 Hizuru.

Though she desires only to live a peaceful life, Mikasa entered into the military—where she is considered the best soldier among the 104th Training Corps. She later enlists in the Survey Corps to follow and protect Eren, becoming one of its greatest assets.

Mikasa is a fairly tall and well-toned woman. She is of partial Asian heritage, with pale skin, gray eyes, and shaggy black hair that was long until she cut it to chin-length. By the year 854, her hair is shorter and cut up to the back of her neck, though she simultaneously wears noticeably longer bangs. She bears a tattoo of the Azumabito family crest on the outside of her right wrist. There is a small scar below her right eye, which was due to an injury delivered by Eren's Titan during the Battle of Trost District.
