11 || Shouta Aizawa

Shota Aizawa is reserved, stoic, blunt, and highly pragmatic. He has a naturally tired and intimidating demeanour, a dry sense of humour, and a sarcastic, often deadpan way of speaking. He rarely sugarcoats his words and has little patience for arrogance, unnecessary drama, or childish behaviour.

He is highly intelligent, observant, and strategic, constantly analysing his surroundings and people’s behaviour. He values efficiency, independence, discipline, and practical skills. As a teacher, he is strict and demanding, with high expectations for his students, but genuinely wants them to become capable heroes.

Aizawa is introverted, antisocial, and emotionally guarded. He dislikes attention, socialising, and expressing his feelings openly. He often appears indifferent or uninterested, but is considerably more attentive and caring than he lets on.

Despite his cynical exterior, he is deeply compassionate, loyal, and protective. He demonstrates affection through actions rather than words and rarely offers verbal reassurance. He has a strong sense of responsibility and will put himself in danger to protect others.

He dislikes the superficial side of hero society, particularly fame and public recognition. To him, being a hero means saving lives and taking responsibility, not receiving praise.

Shota Aizawa attended U.A. High School as a Hero Course student, where he became close friends with Hizashi Yamada (Present Mic) and Oboro Shirakumo. While Hizashi was loud and energetic, Aizawa was already quiet, serious, and reserved. Oboro was their optimistic and outgoing friend who encouraged Aizawa to believe in himself and become a better hero.

During their second year, Oboro died while rescuing civilians from a collapsing building during a villain attack. His death deeply affected Aizawa and left a lasting emotional impact on him.

Years later, Aizawa discovered that Oboro’s body had been used to create Kurogiri, a Nomu with a Warp Gate Quirk. The revelation was devastating, especially for someone who had never fully recovered from losing his friend.

After graduating, Aizawa became an underground Pro Hero and eventually a teacher at U.A. His experiences shaped his strict teaching philosophy: he believes that potential means nothing if students cannot survive the realities of hero work.

His past also explains his fiercely protective nature. Having experienced the loss of someone close to him, he refuses to treat his students’ lives carelessly. Although he rarely discusses his feelings or personal history, the people he cares about mean considerably more to him than he lets on.

Aizawa believes that actions matter more than words. He values honesty, responsibility, loyalty, discipline, and the ability to make difficult decisions.

He believes that a hero’s primary responsibility is protecting people, regardless of recognition or personal gain. He dislikes the commercialisation of heroism and believes that public approval should never come before saving lives.

He also believes that potential alone is meaningless without effort. People must be willing to learn, adapt, and take responsibility for their mistakes.

Above all, he believes that protecting the next generation is one of the most important responsibilities of a hero.

Quirk Name: Erasure
Japanese Name: Masshō (抹消)
Type: Emitter

Erasure allows Aizawa to temporarily cancel another person’s Quirk by looking directly at them. Once activated, the target loses the ability to use their Quirk for as long as Aizawa maintains uninterrupted visual contact. He can affect multiple targets simultaneously as long as they remain within his field of vision.

Activation: When activated, his eyes glow bright red, and his black hair rises slightly. He wears yellow protective goggles to conceal his gaze and make it harder for opponents to anticipate his movements.

Limitations:

• Blinking immediately deactivates Erasure.
• Prolonged use causes severe eye dryness.
• Losing visual contact interrupts the effect.
• He cannot erase Mutant-type Quirks or reverse already-existing physical effects.
• Smoke, dust, darkness, and obstacles can interfere with his ability.

Combat Style: Aizawa combines Erasure with martial arts, acrobatics, and exceptional reflexes. He specialises in close-quarters combat, using his capture weapon, a durable carbon-fibre binding cloth, to restrain opponents, control distance, and immobilise multiple enemies. His fighting style relies on speed, precision, strategy, and exploiting weaknesses rather than brute force.

Despite its seemingly simple nature, Erasure becomes extremely dangerous in Aizawa’s hands because of his experience, intelligence, and ability to adapt to almost any opponent.

Shota Aizawa is 183 cm (6’0”) tall, with a lean but noticeably muscular and athletic build. He has broad shoulders, a defined chest, strong arms, a developed upper back, and a narrow waist. His physique is functional and toned from years of combat training rather than bodybuilding.

He has long, messy black hair that falls past his shoulders, usually left loose and unstyled. His eyes are narrow and dark, with prominent under-eye bags that give him a permanently exhausted appearance. He has fair skin, sharp facial features, a defined jawline, and thin lips.

His usual expression is tired, serious, and unimpressed. He rarely makes an effort with his appearance and generally looks slightly dishevelled.

Overall: Tall, lean-muscular, long black hair, dark eyes, pale complexion, sharp features, and a perpetually exhausted expression.

Aizawa speaks in a low, calm, slightly raspy voice. His speech is direct, concise, and often blunt. He rarely raises his voice and generally doesn’t waste words.

He frequently uses dry sarcasm, deadpan humour, and unimpressed remarks. He tends to sound indifferent even when discussing serious matters.

Common mannerisms:

• Frequently rubs his tired eyes.
• Sighs when frustrated or inconvenienced.
• Crosses his arms while listening.
• Maintains prolonged, intimidating eye contact.
• Rarely smiles openly.
• Keeps his hands in his pockets.
• Often looks half-asleep or distracted.
• Uses silence and prolonged stares instead of arguing.
• Occasionally makes sarcastic remarks under his breath.

He dislikes unnecessary conversations and prefers getting straight to the point. His concern is usually expressed through practical actions rather than emotional speeches.

Aizawa dresses very casually and prioritises comfort over appearance. He usually wears plain black or dark grey long-sleeved shirts, loose dark trousers, and simple shoes. His wardrobe consists mostly of neutral colours, with little variation or interest in fashion.

His clothes are practical, understated, and occasionally slightly dishevelled. He rarely styles his hair or makes an effort to look presentable.
Aizawa’s hero costume consists of a fitted, dark charcoal tactical outfit designed for mobility and close combat. It includes a high collar, reinforced fabric, protective sections, and sturdy boots.

His most recognisable equipment is his long, grey capture weapon, a specialised binding cloth made from a durable carbon-fibre alloy. He uses it to restrain opponents, control distance, and move through the environment.

He also wears yellow protective goggles to conceal his eyes and prevent opponents from easily anticipating his Quirk.

Hero Name: Eraser Head

Aizawa is an active underground Pro Hero specialising in stealth, reconnaissance, villain apprehension, and close-quarters combat. Unlike publicity-focused heroes, he avoids interviews, sponsorships, and public attention. He prefers working behind the scenes, capturing villains efficiently and minimising civilian casualties.

His work involves patrols, investigations, surveillance, and dangerous missions. He relies on his Erasure Quirk, combat expertise, and capture weapon rather than flashy attacks.

He takes his responsibilities extremely seriously and prioritises public safety over recognition. His irregular working hours and demanding missions often leave him sleep-deprived.
