Azumabito family (Anime)

The oriental clan (東洋の一族) is a bloodline within the Walls originating from a land in the far east.

Battle of Trost District arc
During the Battle of Trost District, Mikasa Ackermann recalls the time from her childhood when her mother and father were killed by human traffickers who were hoping to sell her and her mother to potential buyers in the underground city. She is rescued by Eren Jaeger, killing two of the traffickers before Mikasa kills the third with her awakened Ackerman abilities. After the death of her mother, Mikasa Ackerman becomes the last surviving member of the Asian bloodline known to exist within the Walls.

Trivia

 * In the manga, the oriental clan possesses a special tattoo-like brand passed down from generation to generation, which Mikasa receives from her mother shortly before her parents are murdered. In the anime and the visual novel, this brand is replaced with a unique stitching method.
 * Due to the etymology of Mikasa's name, it is likely that the oriental bloodline is based more specifically on the people of the Japanese islands, though Hajime Isayama has stated that the "East Sea" of the Attack on Titan world is different than the East Sea of the real world.
