Mikasa Ackermann is the adoptive sister of Eren Yeager, the childhood friend of Armin Arlert, and the last descendant of the Shogun clan that stayed on Paradis Island. She is a member of the Survey Corps, an elite military branch that fights against the Titans, giant humanoid creatures that devour humans.

Mikasa Ackermann's Personality

Mikasa is a calm, stoic, and rational person who rarely shows her emotions. She is very intelligent and observant, able to quickly assess situations and act accordingly. She is also very brave and determined, willing to face any danger and overcome any obstacle to protect her loved ones and achieve her goals. She is loyal to her comrades and respects her superiors, but she will not hesitate to disobey orders or challenge authority if she believes they are wrong or endangering Eren.

Mikasa’s personality was shaped by her traumatic childhood, when she witnessed the murder of her parents by human traffickers who tried to kidnap her. She was rescued by Eren, who killed two of the kidnappers and gave her a scarf, which she cherishes as a symbol of his kindness and warmth. Eren also taught her to fight for her survival and freedom, and to never give up hope. Mikasa developed a strong bond with Eren, and became his adoptive sister after his parents took her in. She also befriended Armin, who shared Eren’s dream of seeing the outside world beyond the walls.

Mikasa’s life changed drastically when the Colossal Titan breached the outermost wall of their hometown, Shiganshina, and unleashed a horde of Titans that invaded the district. Mikasa witnessed the death of Eren’s mother, who was eaten by a Titan, and escaped with Eren and Armin to the inner wall. She then joined the military training corps, where she excelled in all aspects of combat and graduated as the top of her class. She followed Eren into the Survey Corps, where she learned that he had the ability to transform into a Titan and use it to fight against the enemy. She vowed to protect him at all costs, even if it meant going against the military or the government, who viewed Eren as a threat or a weapon.

Mikasa’s personality has evolved throughout the series, as she faced various challenges and conflicts. She became more independent and confident, as she learned to trust her own judgment and skills. She also became more expressive and compassionate, as she showed more emotions and empathy towards others. She developed friendships and bonds with her fellow soldiers, such as Levi, Sasha, Connie, Jean, and Historia. She also grew to respect and admire Erwin, the commander of the Survey Corps, who sacrificed himself for the sake of humanity. She also learned to accept and support Eren’s decisions, even if they conflicted with her own, and to respect his freedom and choices.

However, Mikasa’s personality also has its flaws and weaknesses. She can be overprotective and possessive of Eren, sometimes to the point of obsession. She can also be stubborn and reckless, often putting herself in danger for his sake. She can also be cold and ruthless towards her enemies, especially those who harm or threaten Eren. She has a hard time coping with loss and grief, and tends to isolate herself from others. She also struggles with her identity and purpose, as she questions her role and place in the world.
