The Asian clan originated from the Asian inhabitants of Hizuru near the eastern sea. During the Great Titan War, some of them joined the Eldian refugees inside the three Walls on the island of Paradis.
When the First King erased the memories of the Eldians inside the Walls, the Asian clan was unaffected due to not being Subjects of Ymir. After turning against the Royal Government alongside the Ackerman family and rejecting the King's offer of nobility, the Asian bloodline was exiled from society and hunted down. By the year 844, it was said that the Asians had been hunted down to near extinction within the Walls.
During the Battle of Trost District, Mikasa Ackerman 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 Mitras. She is rescued by Eren Yeager, 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.
In a conversation with Levi Ackerman before their confrontation with Kenny Ackerman and his subordinates, Mikasa mentions how her mother's family lost their home, possibly due to their Asian heritage.
- In the manga, the Asian family possesses a special tattoo-like brand passed down from generation to generation, which Mikasa received from her mother shortly before she 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 and of Hizuru, the Asian clan may have been based specifically on the people of Japan.
