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 village was attacked by pirates. She is the last descendant of the Shogun clan that immigrated from Wano, thereby related to the Azumabito family, and holds significant political power back in the flower capital.
Though she desires only to live a peaceful life, Mikasa entered into the marines—where she is considered the best cadets from the 16th Branch. She later defects to join the Revolutionary Army to follow and protect Eren, becoming one of its greatest assets. She is currently serving as an officer in the North Army.
Appearance
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 time she turned 19, 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 a stray bullet during a fight against a pirate crew.
Personality
Before living with the Yeager family, Mikasa appeared to be a cheerful, outgoing, and gentle child. Her innocence allowed her to push anxious thoughts to the back of her mind, continuing to live with her parents and loved ones happily. Growing up, Mikasa has become emotionally withdrawn and noticeably dangerous, sometimes intimidating her enemies or even her comrades. She is quite stoic and level headed, rarely seen to lose her cool or be at a loss of what to do, no matter how bleak the situation seems to be. Her will is remarkably strong, demonstrated when she managed to remain so outwardly calm when Eren was presumed dead; only Armin could tell that she was battling with the pain of losing him.
Mikasa cares deeply for her friends and caretakers, seeing them as the last remnants of a family she cannot afford to lose. She also appears to have a soft spot for children, evidenced by her bowing to a young girl she saved and her instantly saving a pirate apprentice from the Marley crew, despite the latter having earlier killed one of her comrades. Mikasa is not completely immune to the effects of her emotions, however: Her strong feelings for her beloved ones, particularly when they are in harm's way, does at times cloud her judgment in fury—sometimes to the endangerment of herself and others. A notable example was when Mikasa briefly gave in to her grief over Eren's apparent demise and lost the will to live, forgetting her responsibility for the lives of her fellow cadets she took upon herself to lead in the process. However, she was reawakened by her memories of Eren and a made decision to never give up again, as her memories would die with her.
From an early age, Mikasa was unusually perceptive, aware of the harshness of nature by witnessing the manner in which predators hunt and kill weaker prey. Her peace was shattered when a band of criminals brutally murdered her parents before her eyes in a failed kidnapping attempt, only saving herself and her rescuer when she managed to abandon all inhibition and hesitation to kill one of her assailants. Following this traumatic event, Mikasa would gain a generally cynical outlook on life and accept the world as a cruel place where only those who are strong are able to survive. Her determination to protect her beloved ones as much as possible has contributed greatly to her phenomenal skills as a soldier. Though being among the best of the best, she remains humble and refrains from putting on airs or displaying arrogance.
Mikasa has a strong sense of right and wrong, doing everything she can to make her most impulsive friends follow what she thinks is the right track. In spite of this, she is well aware that she cannot always sway them in decisions and makes it a point to follow them wherever they go, just so that she can be around to help out when trouble arises. The sole reason she enlisted in the Marines and joined the Revolutionary Army after defecting was to keep an eye on Eren, despite the fact that she truly wished to live out the rest of her days in relative peace back in the East Blue alongside him.
Mikasa's bond with Eren is undoubtedly her most important relationship and the one that defines her. Her personality as a teenager was very much influenced by Eren, who told her she stood no chance of survival if she did not fight for it. His words continued to stay with her, and she automatically recalled them to spur her on when she was close to death. Mikasa wears the red scarf Eren gave her when they first met, holding on to it as a source of strength and comfort when she is upset. She had openly wept tears of relief at his safety and developed vengeful grudges towards those who harm him, from enemies to her own superiors. She blushed when it was insinuated she and Eren were lovers; furthermore, after he insulted her and stated that he had always hated her, she was visibly hurt and eventually left behind the scarf he had given her.
While she would regain the scarf from Louise, Mikasa would not wear it again until moments before confronting Eren following his initiation of the Mariejois invasion. Mikasa's sacrifice of a life with her beloved Eren and choosing to defy and kill him is ultimately the reason why the Revolutionary Army was able to retreat after the first attempt at taking down the Celestial Dragons. Mikasa grieves for Eren as she visits his grave, and would continue to regularly visit it with her new family for several decades until passing away of old age while wearing the scarf.
History
Mikasa was born to a mother from Wano, and her father was a member of the D clan. She lived peacefully with her parents in the farmlands of the Conomi islands, helping them since a young age. Mikasa underwent a painful scarring ritual from her mother, who cut into her skin the mark of their family.
Being from Wano made her mother and Mikasa high value targets to robbers. When she was only 9 years old, a group of traffickers killed her parents and attempted to kidnap her for the purpose of selling her in the human-trading market of Sabaody Archipelago. Frightened and shocked, Mikasa was rescued by Eren Yeager, the son of her family's doctor. He tricked and killed two of the kidnappers, but he was overwhelmed by the third trafficker and on the verge of being strangled. Eren desperately urged Mikasa to fight to win, who came to realize that the world can be callous and merciless before dispatching the robber from behind, who was trying to kill him.
When Grisha Yeager arrived with members of the Marines, Mikasa was given the scarf by Eren and accepted into his family. This event awakened her Observation Haki even if she didn't know what it was at the time. Mikasa then went to live with Eren's family until Cocoyasi was raided by pirates.
Abilities
Strength
Owing to the need to protect Eren who often runs off looking for trouble, Mikasa had honed herself to be a talented fighter at a very young age. She often threw boys bigger than her with ease and scared them enough to run away upon seeing her despite their superior numbers. Having undergone intense training, Mikasa is strong enough to lift Eren and several equipment boxes off the ground without effort.
Haki
She can use Observation and Armanent Haki.
Relationships
Mikasa's mother and father - Mikasa shared a loving bond with her parents, and was happy with the simple life they shared. Being from a prominent clan from Wano, Mikasa's mother had Mikasa undergo a scarring ritual involving the engraving of their clan's mark on her right forearm. She praised Mikasa for receiving the mark without making a fuss and encouraged her to carry on the legacy with her own children. Mr. Ackerman was a kind father to Mikasa, and she was very relaxed around him. She was not shy of asking either parent anything she did not know, and trusted them completely. The day a trio of robbers attacked and killed her parents in front of her, Mikasa lost all hope and believed her world had gone cold until Eren's father decided to take her in.
Grisha Yeager - Though he initially hoped Mikasa would get along with Eren as a friend, in the end Grisha took in Mikasa after the brutal murder of her parents. He treated her kindly as if she were his own daughter, and for that Mikasa respected and gratefully relied on him as a father figure.
Carla Yeager - Carla took care of Mikasa during her stay in the Yeager household. Much like her husband and son, she treated Mikasa as a family member and took care of her. The two seemed to have an implicit understanding between them when it came to keeping Eren out of trouble. Carla urged Mikasa to look out for Eren and give him help when he needed it. During the pirate raid on their village, she desperately tried to lift the roof beam preventing Carla from running away from the danger. Despite Carla's pleas, she tearfully refused to leave her and could not bring herself to watch as a pirate eventually shot and killed her.
Eren Yeager - She always wears a scarf, given to her by Eren, as a token of the moment when he first wrapped it around her in an attempt to comfort her when she had first lost all hope. From the time he saved her life and accepted her into his home, Eren had been a great source of strength and comfort for her, and when she had thought him dead, she very nearly allowed herself to die as well, but kept living on to remember him, and when he turned out to be alive, she bursted out in tears of relief. She became distraught when learning Eren had been abducted, wrapping the scarf over her face to hide her sadness. Because he was the only family she had left, she would go to any lengths to ensure his safety, and vowed to follow him wherever he may go, stating her only wish was to remain by his side. Due to Mikasa's protective nature over him, Eren often became annoyed and told her not to treat him like her baby brother. Because of her intense devotion to him, several people, from Ian to Jean and even Levi, are confused about the nature of their relationship. Interestingly, Mikasa only ever blushed when Eren was involved. Examples of this include her embarrassed blush when Ian mistook him for her lover during their time as Marines, Armin leaving her alone with Eren after they officially defected from the Marines, and, when she believed she was about to die, thanked Eren for everything he had done for her. After arriving in the New World, Eren asked Mikasa about what he meant to her. Mikasa stammered a little before replying that he was "family," as the others arrive and interrupt them, disappointing Eren. Their relationship somewhat suffers after the Battle of Sabaody; seeing Eren seemingly dismissive of her concerns about the numerous innocent civilians he killed prompts Mikasa to see that he had become colder and more detached, worrying her about his overall state of mind. Their bond was, at least temporarily, tested once Eren seemingly fully committed to the Yeagerists and insulted her, claiming he had always hated her. During the start of the Mariejois invasion, Mikasa recalled back to Eren's question of their bond, wondering if things would be different had she given a different answer. She was determined not to kill Eren and simply bring him back to his senses; however, when Eren stated that the only way to stop him was by fighting and killing, Mikasa was extremely torn by this revelation. Mikasa would continue to mourn Eren while visiting his grave for decades with her new family until passing away of old age while wearing his scarf.
Armin Arlert - Mikasa is a very close friend of Armin's. She frequently helped Eren fend off the older boys who bullied him when they were children. Mikasa recognizes Armin's ability to reason out the best solution and come up with the best strategy during dire situations, and is faithful to him and trusts him deeply, as shown when she refused to leave him behind to his death during their first mission as revolutionaries. She encouraged him to have more confidence in himself whenever he doubted or criticized himself. Her faith in him, along with Eren's, were responsible for Armin's boost in confidence from the time he attempted to convince a hostile brigade of Marines of Eren's value as a Marine. Additionally, when Armin was dying from being almost burned to death she is seen breaking down because Levi would not give Armin the Hormone injection, staging a mutiny to get Armin revived, demonstrating how much she cares for his well-being, and when he is brought back, she smiles with tears flowing down her face. Years later, after the Battle of Sabaody and Eren's betrayal, Mikasa has come to rely on Armin for emotional support and reassurance, the pair often accompanying one another.
Hannes - it is implied that Mikasa was grateful towards Hannes for rescuing her and Eren from being killed by the pirate that killed Eren's mother. Despite admitting to his cowardice in front of her, she did not resent him for failing to rescue Carla, and she valued him as one of the few people left with whom she shared memories of more peaceful times. Hannes comforted her when she was depressed over losing Eren, and also encouraged Mikasa not to give up, which snapped her out of her grief. When she was seriously injured, Hannes defended both her and Eren from the higher-ups of the Marines, only to lose his life in the end. Retreating to the safety of Baltigo, Mikasa appeared to be in anguish over his loss, and still grieves for Hannes with Eren and Armin.
Annie Leonhart - Mikasa had a rivalry with Annie when they were both part of the Marines. This would turn into outright animosity once Annie was confirmed to be a spy from the pirate crew who had raided their village as kids and Eren's attempted kidnapping. Mikasa is likely jealous of Annie's relationship with Eren, since she throws Reiner bodily on top of Eren and Annie in order to interrupt their training when Annie is demonstrating how to do a throw. It appears that her hatred towards Annie has cooled off considerably once she escaped from Impel Down and joined the Revolutionary Army; Mikasa would even console Annie as the latter would comment how she was done fighting for people who have treated her poorly all throughout her life.
Reiner Braun and Bertolt Hoover - It is not known if Mikasa had any interaction with either Reiner or Bertolt but after it is revealed they were members of the crew that raided Cocoyasi, Mikasa has shown nothing but rage and anger towards them. However, Mikasa realizes that when she attacked both of them after Reiner revealed their identities as spies, she hesitated and was unable to finish them off. She agonizes over this failure, recognizing that she should have been able to kill them with her level of skill. When she finally caught up to them, she flew into a murderous rage, threatening Ymir and even Krista when they came between her and the traitors. Calling them a "plague upon humanity," and stating that there is no reason to care what their reasons and motivations might be, she also encouraged the others to kill them without mercy. However, her rampage was stalled by Bertolt's emotional confession. While it is currently unknown if her feelings towards the two have changed over the following years, it is known that Mikasa has at least temporarily put aside her animosity towards Reiner and is willing to work alongside him once he joined the Revolutionary Army.
Jean Kirstein - Her primary interactions with him relate to his rivalry with Eren, and it is unclear whether she is even aware of his affections for her. When he grimly admonished Eren for attacking her, Mikasa felt Jean was attempting to discredit Eren, and quickly became defensive on his behalf. It is implied that he continues to harbor feelings for Mikasa, as he lost his composure when he saw a Celestial Dragon had grabbed her and declared that she was to marry him, and furiously attacked the man head-on in order to save her.
Sasha Blouse - Though the two have distinct personalities. Mikasa respected Sasha's instincts. Sasha and Mikasa get along really well as the two have been roommates since their cadet days. Even though Sasha snores in her sleep, Mikasa does not seem to mind. The two joked around and were close enough for Mikasa considers to her be one of her closest friends besides Eren and Armin. When Jean told the others about Sasha getting shot and that Sasha would not make it, Mikasa ran out of the room to be by Sasha's side. When Sasha died Mikasa shaked Sasha's body in a vague attempt to ring her back. Sasha's death distressed her immensely. After Sasha's funeral Mikasa stayed by her grave and started talking about what had to be done for her friends to live freely.
Louise - After Mikasa saved a young Louise and her mother from Pirates, Mikasa left an indelible impression on the girl. After this, Lousie began idolizing Mikasa, which ultimately became her primary reason for joining the Marines. Years later, Mikasa reunites with Louise but is slightly put off by her constant idolization and also disapproves of how she has decided to follow Eren and his plan to eradicate the Celestial Dragons. Nevertheless, Louise continues to look up to Mikasa for strength and leadership, wanting to get closer to her. When Mikasa came to a hospital for her scarf where a dying Louise was in, the latter revealed her motivation of how Mikasa inspired her to join the Marines and devote her heart. However, Mikasa demands her scarf back and silently leaves, remaining indifferent to Louise's integrity.
Levi D. Ackerman - Their relationship began in a negative fashion, as she witnessed him beat Eren during their time as Marines. She once swore to make him pay for his abuse and lashed out at him when a disguised pirate managed to kidnap Eren after slaughtering Levi's squad. Regardless, he expresses an understanding of her and is wounded saving her life—while temporarily sidelined, he repeatedly offers her advice, and she herself agonizes over causing his injury. It is unknown if she still bears a profound grudge against him, though she eventually comes to accept his leadership. They both share the last name Ackerman, although their exact relationship is unknown.
