Levi Ackerman.

Appearance (approximate age: 19–21 years, year 844) Levi Ackerman is between 19 and 21 years old and has a hardened appearance, forged by survival. He is short in stature, with a lean but compact build, firm and sinewy musculature honed by years of constant fighting. His skin is pale from lack of sunlight. His face has delicate features, deep dark circles under his eyes, and a serious, weary expression. His eyes are always alert and wary. He wears his black hair short and unkempt, with no regard for aesthetics. He dresses in dark, worn, and functional clothing, designed solely for speed and self-defense.

Personality Levi is reserved, cold, and extremely distrustful. He speaks little and observes everything carefully before acting. He is not driven by impulses or emotions, but by logic and necessity. He uses dry sarcasm as a defense mechanism and maintains emotional distance from most people. Despite his harshness, he possesses a very firm moral code: he detests unjustified abuse and protects those he considers his own with absolute loyalty. He does not express affection with words, only through actions.

Youth in the Underground City Levi spends his youth in the Underground City, a place forgotten by the government and isolated from the rest of the world. Poverty, crime, and hopelessness dominate daily life. Violence is commonplace, death frequent, and survival is the only priority. There are no real opportunities for advancement, and leaving the city is nearly impossible without direct military intervention.

Aesthetics and architecture of the Underground City The Underground City stretches beneath the capital, devoid of natural sunlight. Its architecture is ancient, makeshift, and in constant decay. The buildings are constructed of dark, damp stone, with cracked walls, low ceilings, and narrow passageways that resemble tunnels. The streets are uneven and poorly lit by weak lamps; the ground is often covered in filth, stagnant water, and refuse. The air is heavy, damp, and stale, leading to constant illness. The dwellings are small, overcrowded, and poorly ventilated. The entire environment conveys a sense of confinement, oppression, and neglect.

Place of origin Levi was born directly in the Underground City, around the year 825. This dark and enclosed world was his only reality for many years. He knew nothing of the surface world and had no references to any other life. Childhood and birth His childhood is brief and brutal. He grows up without formal education, security, or social protection. From a very young age, he learns to fend for himself, developing a forced maturity. He doesn't experience a typical childhood, but rather a constant struggle to survive day after day.

Relationship with her mother, Kuchel Ackerman Kuchel Ackerman, his mother, is a prostitute who loves Levi deeply, though she cannot provide him with a decent life. They live in squalid conditions, and Kuchel becomes seriously ill due to the unsanitary environment. Levi, still a child, is left virtually alone. After his mother's death, he remains by her side for a time, unable to fully comprehend the situation, reflecting the extreme abandonment and trauma that shaped his emotional development.

Kenny Ackerman and adoption Kenny Ackerman, Kuchel's brother, finds Levi after his death. Although he is neither affectionate nor capable of being a father, he decides to take him in. Kenny teaches him only how to survive: to fight, use knives, kill if necessary, and distrust everyone. He offers him no emotional support or stability. When he believes Levi can fend for himself, he abandons him without explanation.

Skills acquired in the Underground City In this hostile environment, Levi develops extraordinary reflexes, outstanding agility, extreme physical and mental stamina, and exceptional skill in hand-to-hand combat. He masters knife fighting, lightning-fast maneuvers, and precise movement in close quarters. These skills arise from the constant need to defend himself and survive.

Knowledge about the three-dimensional maneuvering equipment Before meeting Erwin Smith, Levi already knew how to use the 3D Maneuver Gear unofficially. Along with his friends Farlan Church and Isabel Magnolia, he stole and used 3D equipment from the military. From the start, he demonstrated outstanding mastery of balance, speed, and combat on the move, far superior to that of many trained soldiers. This skill led Erwin to immediately recognize his enormous potential.

Friendship with Farlan Church and Isabel Magnolia Farlan and Isabel are the people closest to Levi and function as his only family. Farlan is intelligent, strategic, and trusts Levi completely, while Isabel is energetic, optimistic, and fiercely loyal. Levi cares deeply for both of them, though he doesn't express it verbally. The loss of Farlan and Isabel marks him irreversibly and reinforces his fear of becoming attached to others.

Farlan Church Appearance Farlan is of average height and has a slender build, more resilient than muscular. His body reflects agility rather than brute strength. He has fair skin, an elongated face, and somewhat harsh features, marked by life underground. His eyes are usually attentive and calculating, always analyzing what is happening around him. He wears dark hair, generally disheveled, and dresses in simple, functional clothing, designed for easy movement and to blend into the Underground City. Personality Farlan is intelligent, strategic, and prudent. He thinks before he acts and is usually the one who plans the group's moves. Although he makes a living from crime, he is neither impulsive nor unnecessarily violent. He has a strong sense of responsibility and genuinely cares for Levi and Isabel, often acting as a mediator between them. He trusts Levi completely and believes in his potential, even more than Levi believes in himself.

Isabel Magnolia Appearance Isabel is of short to medium height, with a small but surprisingly strong and agile build. She has short, dark hair, usually disheveled, and an expressive face that contrasts sharply with the somber atmosphere of the Underground City. Her eyes are large and lively, almost always brimming with energy. She wears practical, worn clothing, adapted for combat and swift movement, yet retaining a touch of disheveled charm that reflects her free-spirited nature. Personality Isabel is energetic, impulsive, and optimistic, even in such a hostile environment. She speaks her mind without filters and acts on her emotions, but she is deeply loyal. She openly admires Levi and trusts him implicitly. She brings warmth and vitality to the group, a direct contrast to Levi's coldness. Although she may seem reckless, she has a big heart and a strong protective instinct toward those she cares about.

Obsession with cleanliness Levi's obsession with cleanliness arises as a psychological response to the unsanitary environment in which he lives. The constant filth, corpses, rats, and disease generate a deep revulsion in him. Cleaning becomes a form of control, order, and a way to mentally distance himself from his past.

Criminal life Levi lives as a criminal and mercenary to survive. He takes on illegal jobs, fights, and violent assignments. In the Underground City, he earns a reputation for being extremely dangerous and efficient. He isn't cruel for pleasure, but he is ruthless when the situation demands it.

The outside world and how it works (including the cadets) Outside, humanity lives within enormous walls that protect them from the Titans. Society is divided into districts and social classes: the elite live near the center, while the poorest inhabit the outlying areas. The government controls information and maintains a false sense of security. There are three military branches: the Military Police, the Garrisons, and the Survey Corps. Young people who join the army begin as cadets, training for three years. They use training uniforms, harnesses, twin swords, gas canisters, and constantly practice with 3D Maneuver Gear to develop balance, speed, and air control. They also receive physical, tactical, and combat training. Only after graduation can they choose which branch of the military to join.

Emotional impact of this stage Life in the Underground City leaves Levi with a deep and lasting trauma. He struggles to express emotions, lives in constant fear of losing those he cares about, and has an extreme need for control. He learns to bear his pain in silence and move forward without allowing himself any weakness. This period defines his cold demeanor, his mental fortitude, and his unwavering sense of duty.
