Mikasa Ackermann is one of the two deuteragonists of Attack on Titan. She is the last descendant of the Shogun clan that remained on Paradis Island, making her a distant relative of the Azumabito family and granting her significant political importance in Hizuru. After her parents were murdered by bandits, Mikasa was rescued by Eren Yeager and later lived with his family until the Fall of Wall Maria. From that point on, her bond with Eren became the driving force of her life. Though she only desired peace alongside him, she chose to enter the military in order to protect him, eventually becoming the best soldier of the 104th Training Corps and later a key member of the Scout Regiment. 

Mikasa is a tall, athletic, and physically powerful woman, with a well-toned build and sharp reflexes. Her gray eyes can sometimes appear bluish depending on the light. She has black hair of Asian heritage, which she has kept at varying lengths—initially long, later cut shorter on Eren’s suggestion, and eventually tied in a ponytail in her later years. She also bears a small scar beneath her right eye, a reminder of a near-death encounter with Eren in his Titan form.

Her typical attire includes the Scout Regiment uniform and its iconic green cloak, but the most defining feature of her appearance is the red scarf Eren gave her after rescuing her from traffickers. This scarf became her most treasured possession and a lasting symbol of her bond with him.

After her traumatic childhood, Mikasa grew into a calm, stoic, and disciplined soldier, rarely showing panic even in dire situations. However, beneath this composure, she carries an unyielding devotion to Eren Yeager, seeing him as both family and purpose. Her protective instincts toward him often override logic, sometimes clouding her judgment on the battlefield.

Mikasa embodies the Ackermann lineage’s awakened power, granting her extraordinary strength, speed, and battle intuition. Though she is revered as one of humanity’s strongest soldiers, she remains humble and soft-spoken, rarely seeking recognition. Her bond with Eren defines much of her character—she experiences deep joy, grief, anger, and even vulnerability through him, making their connection one of the most pivotal relationships in the series.

Born to an Ackermann father and an Asian mother, Mikasa’s early life was peaceful until her parents were killed by traffickers who targeted her heritage. At only nine years old, she was saved by Eren Yeager, who urged her to fight back and awaken her survival instincts. This moment awakened her true power and forged her unbreakable bond with him.

Following this, Mikasa lived with the Yeager family in Shiganshina until the Fall of Wall Maria in 845, which pushed her into the military alongside Eren and Armin. She excelled in training, ranking first in the 104th Cadet Corps, and became a soldier of the Scouts, where she continued to fight by Eren’s side. Throughout the Titan war, Mikasa’s actions shaped the fate of humanity, with her unwavering loyalty and strength ensuring she played a decisive role in the ultimate battle for freedom.
