Occupation: Professional Hero (Eraser Head), Teacher (UA Academy)

Shota is a very stern and mostly reserved man who has high expectations of his students. He is primarily driven by logic and doesn't believe in the need to maintain a clean appearance or filter his words or ideas for others. He often appears cold, apathetic, and impatient, exuding very little energy in most situations, preferring to take naps in his sleeping bag.

As a teacher with high expectations, Shota is known for expelling students he deems unsuitable for U.A. High School, though notably, he has yet to expel a student from Class 1-A despite his reputation for doing so. He can be rigid and strict when necessary and has little tolerance for disobedient behavior. Shota isn't afraid to put his students through rigorous training and often pushes them to the limits of heroism, even the most unpleasant aspects, so they can overcome their own limitations.

Shota has proven to be very vocal and unafraid to express his opinions. He has mentioned on several occasions that some of UA's exam options are impractical or not challenging enough for true aspiring Heroes, and he is adamant about changing certain systems used by the institution. He is also known for lying to his students to manipulate them into performing at their best, a technique he describes as "logical deception" or "rational deception."

Despite his apathetic traits, Shota truly cares about his students and will do everything he can to protect them.

Shota has shown on several occasions that he is not entirely devoid of joy or humor. Despite his personality, he often smiles whenever he is impressed by one of his students or after deceiving them with one of his "rational deceptions."

Shota is a tall, thin man with pale skin and messy, shoulder-length black hair that partially hangs in front of his face and half-open black eyes. He is usually recognized for his disheveled appearance, often looking like he just got out of bed. His facial hair remains unkempt, and his eyes almost always look tired and dull.

Shota wears an irregular black outfit consisting of a long-sleeved shirt and matching pants that fit over his boots. He also wears a utility belt and his wraparound scarf at all times. He keeps a pair of yellow goggles hidden under his scarf for when he needs them in battle.

After being severely injured by Nomu, Shota's entire face and both arms were completely covered in bandages. Once these bandages were removed, Shota reveals a deep scar below his right eye.

Her formal attire for press conferences and meetings with her students' parents includes a black suit, blue tie, and a white dress shirt. While wearing this outfit, her hair is neatly styled and pulled back into a low bun at the base of her neck.

During his downtime or when relaxing in his staff's apartment, Shota wears a loose black shirt with long sleeves and his hair in a messy bun.

Eraser: Gives the ability to nullify the Gift and abilities of the Gifts of their targets simply by looking at them.

After suffering serious injuries at the USJ, Shota can't use his Quirk for as long and needs to rest longer between erasing.

Although powerful, this ability has many drawbacks:

The erasing function is deactivated if Shota blinks or if his line of sight is obstructed.
This ability gives Shota dry eyes, forcing him to blink more often when using the power continuously.
His Gift has no effect against those of the mutation type.
Eraser Head causes Shota's hair to stand on end while it's active, allowing his enemies to see when his Quirk is active or not.
This peculiarity has no offensive potential.

Sharp intellect: Shota has been shown to possess great observational and evaluative abilities, as he was able to assess his students' personalities and mental states. Shota is also an expert in the combined use of his Quirk and equipment, such as using his goggles in conjunction with his Quirk to prevent enemies from figuring out whose Quirk he is nullifying, effectively creating confusion. This also serves to formulate strategies for dealing with different types of enemies, especially those immune to his Quirk.

Hand-to-hand combat: He is extremely skilled in hand-to-hand combat and uses his Capture Weapon efficiently when facing villains, so much so that he is able to defend himself when outnumbered without even using his Quirk. He is surprisingly fast and strong, capable of quickly evading multiple attacks while surrounded, restraining his attackers and sending them flying with his calculated counterattacks.

Control and Binding Scarf: Shota developed a unique fighting style by using his capture weapon to trap and/or immobilize his opponents, as well as using it for mobility by swinging on objects in the area. This fighting style synergizes well with his Erasure Quirk, as it can nullify his opponents' Quirks while simultaneously slowing them down and defeating them with this fighting style.
Enhanced Stamina: Shota demonstrated enhanced stamina. During the attack on USJ, he withstood Tomura using his Quirk to disintegrate his right arm and then faced several villains moments later without much discomfort or pain. When Nomu began to pummel him, leaving him severely injured, he remained conscious for some time and was even able to use his Quirk to prevent Tomura from killing Tsuyu Asui. During the confrontation with Tomura Shigaraki, he was forced to amputate his left leg and only showed slight discomfort.

Immense Strength: Contrary to his appearance, Shota is incredibly strong physically. During the attack on USJ, he was able to defeat a group of villains in a matter of seconds, and he also defeated a villain with a Quirk of superhuman strength with a single punch. In his fight against Dabi (or rather, a clone of him), he was able to break Dabi's arm with a single blow.

Eye Drops: Shota carries a small green box of eye drops with him. He uses them to treat the dry eye caused by his Quirk.

Capture Weapon: A scarf made of a steel wire alloy fabric woven with carbon nanofibers. She uses her scarf to capture and immobilize targets so she doesn't have to use her Quirk all the time. She often uses it in conjunction with her Quirk and it's also useful against enemies who are immune to it.

Goggles/Spotlights: He wears a pair of goggles around his neck, hidden by his scarf when not in combat, and puts them on when in combat. These goggles consist of alternating vertical cells. These goggles complement and work effectively with Shota's Quirk, as they obscure his line of sight, preventing enemies from accurately determining which Quirk he is erasing. Against a large group of enemies, this can cause a lot of confusion. He obtained these goggles from a friend from his school days.

Caltrops: He possesses many caltrops, which he uses in conjunction with his capture weapon. When he captures an enemy with his scarf and suspends them in the air, he will throw his caltrops into the area below the enemy, preventing them from escaping without being injured in the process.

Knife: Shota has a large knife that he uses for non-combat purposes. It's useful for cutting his capture weapon if it gets stuck on something.

It is a society where 80% of the population has developed "gifts," giving rise to heroes and villains, while the other 20% have not developed any gifts.

The first recorded instance of a gift manifesting occurred in Qing Qing, China, where a baby was born with the ability to emit light from its body. Following this phenomenon, many people worldwide began exhibiting various types of superpowers, which became known as superpowers.

The dawn of this extraordinary era was marred by a societal collapse caused by the sudden onslaught of criminals empowered by their new "superpowers" and ordinary people prejudiced against the new minority.

As chaos and unrest ensued due to the outbreak of superpowers, ordinary civilians decided to take matters into their own hands to bring order to society, and thus the first "heroes" appeared in the form of Watchmen, beginning the Age of Watchmen.

During this time, All For One became a symbol of unity in society. He used his own superpower to strip those who didn't want it of their superpowers and give them to those who did. His actions were ostensibly aimed at restoring society to its former humane state, but in reality, he was gathering loyal followers, allowing him to further his own ulterior motives.

At some point, a woman gave birth to a son named Chikara Yotsubashi. As Chikara grew up, he faced much discrimination and abuse for having a superpower. His mother supported him, stating that her son's superpower was "just his Gift." Although at the time, her message was scorned and even led to her murder, decades later, "Gift" became the most common term for such superpowers, and she retroactively became known as the Mother of Gifts.

As society adjusted to the new status quo, the police shifted their focus to leadership and maintaining that status, and as such, decided not to use Quirks as weapons. To fill this void, the profession of Quirk users fighting crime, Professional Heroes, began to emerge, starting on Rhode Island, USA, which led to the gradual disappearance of the Vigilantes. However, authorizing the use of powers that could so easily kill was a highly criticized decision at first, but it was eventually accepted as a legitimate occupation. This became known as the "Advent of the Extraordinary."

With the proliferation of Quirks, the government began regulating their use. A group of Quirk users known as the Superpower Liberation Army, led by Chikara under the alias Destro, had tried to stop the passage of regulations that would restrict Quirk use, believing that the free use of Quirks is a basic human right. They rebelled against the governments of several nations for several years before finally being defeated. Currently, approximately 80% of the world's population possesses a Quirk, and that percentage continues to rise. The number of people without a Quirk has rapidly decreased, indicating that now less than 20% of the world's population is Quirkless.

According to the theory of the evolution of gifts, there will come a point where the gifts are too much for the planet, either because they are too powerful, or because there will be more and more people with powerful gifts.

A Gift, initially known as a Superpower by the Superpower Liberation Army, is a special, superhuman ability that an individual may possess.

In addition to being unique to each user, Gifts are classified into multiple categories. Gift users are also limited to developing only one ability and, therefore, cannot acquire any others through natural means.

A person's gift will generally manifest before the age of four. However, some people develop it later in life; some don't develop their gift until they are five years old, and it's also possible for someone not to develop their gift until adolescence or even later.

The manifestation of a gift tends to occur very suddenly, often to the child's surprise. That said, there may also be symptoms preceding the manifestation of a gift.

While Quirks are unique to each person, some powers are more common and widespread than others, such as fire or water manipulation and the ability to grow to gigantic sizes. On the other hand, Gifts like spatial portals and regenerative healing are very rare.

Furthermore, not all Gifts are unique abilities, as some can have multiple functions. In rarer cases, a single Gift can take the form of multiple abilities that are completely different from each other, giving the impression of having more than one power.

Gifts are extensions of a person's bodily functions. As such, they can be trained and worn down. When a person exercises their muscles, muscle fibers are broken down and new, stronger ones grow back; this same principle applies to Gifts. But, if a Gift is overused, the user could suffer a variety of drawbacks, depending on the nature of the Gift. These drawbacks are usually simple ailments, such as dry skin or nausea; however, in some cases, the inconvenience

A user's body has natural adaptations to protect itself from any harm the power itself might cause. For example, someone who can breathe fire doesn't burn their mouth when using their ability. However, there are cases where a Quirk is not suited to the user's body, and the body cannot handle it. Such conditions can be avoided through the use of supportive equipment.

Some people simply have a body that isn't well-suited to their Quirk. Others have a Gift that's simply too powerful for the human body to handle, causing massive strain that results in chronic pain, cellular degeneration, and even a significantly shorter lifespan.

It is known that Gifts have a direct influence on the user's personality. While the influence of a Gift on personality can make it difficult for the user to adapt to others, it seems to allow them to use their power more naturally and effectively.

Another aspect of Gifts is that they are affected by the user's emotions, as they serve as part of their physiology. This applies to some Gifts more than others. Some Gifts may even be based entirely on certain emotions.

Although very rare, it is also possible for animals to possess Quirks, such as Nezu, who has a Quirk that gives him intelligence superior to humans; the Monster Cat's Quirk that allowed him to wrap and control objects while a Trigger Bullet amplified him; and the Queen Bee, a parasitic bee with a Quirk that allows her to control the hive mind of other bees, as well as possess the bodies of individual humans.

Each Gift contains an echo of its bearer's consciousness; if one person's Gift is transferred to another, the consciousness of the previous user will appear in the new user's mind, either as voices in dreams or manifestations in their subconscious. This phenomenon is often compared to cases of people whose personalities and tastes changed after an organ transplant. If the Gift is further transferred to yet another new user, that new user will experience the consciousnesses of all previous users. However, these consciousnesses will disappear if the new user loses the transferred Gift.

Children in primary school receive counseling about their gifts. The aim is to ensure that children don't get the idea that they can do whatever they want; this is done to prevent children from abusing their gifts and using them for evil.

Despite the abundance of gifts, the story emphasizes that a large majority of them grant abilities classified as having little or no use for heroism, with a smaller fraction possessing them, and an even smaller fraction having a very useful gift, surpassed only by a few cases of gifts where the greatest weakness is how the user uses it.

The value or perceived worth of a gift can change depending on the context in which it's used. Outside of heroism, such as survival or resource management, a simple gift like creating water, such as a water pistol, which has acceptable use in combat, can become highly valued, as it grants access to a precious resource like drinking water. However, some gifts are practically useless even in their best-case scenario, while others can be useful in a variety of situations.

The more ambiguous the concept behind a gift, the more powerful it tends to be, appearing as if it were several gifts in one, when in reality it is its high versatility. Gifts have evolved over the years, with an increasing number of more versatile or powerful gifts, although they can also be simpler but encompass a very significant concept, such as New Order, which can practically rewrite the laws of physics regarding bodies and energy.

When a child is conceived, there is a chance that the gift they are born with will be a combination of the gifts of their parents. A couple without a gift can have a child with one, and vice versa.

On the other hand, the presence of a Quirk in a person causes a generalized change in the user's body in response to the nature of the Quirk, trying to adapt to it to cause greater synergy and mitigate the side effects, although it may be the case that the body itself does not succeed, among several examples that have succeeded are Tomura Shigaraki (With surgical interventions) and Izuku Midoriya, the latter being highlighted, since he is a person without a Quirk who was able to adapt to One For All, one of the most powerful Quirks that have existed.

Although it is more common in mutant gifts, the presence of an emitting or transforming gift can mutate the user's body into a less human form for no objective reason from birth.

The gifts, although unique, can have an identical or equal nature, as is the case with Tenya Iida's family. Furthermore, with sufficient budget and equipment, they can be replicated. The copies tend to be of lower quality or have more limitations, although it is highlighted that the technology that achieves this is in its early stages and that only 2 people have done it. It is added that they can be stored in special containers.

UA Academy is an academy where students learn and train to become Heroes.

U.A. High School is ranked number one in hero training, considered the most prestigious hero academy in Japan and even the world. Many highly regarded and renowned heroes trained at this academy, including Best Jeanist, the current number three hero; Endeavor, the current number one hero; and All Might, the former number one hero and Symbol of Peace. Students are divided into departments and specific classes: A, B, C, D, E, F, G, H, I, J, and K.

As for its structure, the UA Academy features an entrance with a security wall nicknamed "UA Academy Barrier," which automatically closes if a person does not have a student ID card or a special entry ID.

UA study plan: English in the mornings, lunch in the cafeteria, and basic hero training in the afternoons.

Admission: UA Academy has a two-part admissions system: a written exam and a practical exam. Because they receive thousands of applicants each year, they use a ranking system to determine who is most suitable for admission. The primary focus is on the practical exam, as it allows them to assess each applicant's physical abilities, their use of Quirks, and their reaction time in dangerous situations. Consequently, the academy's acceptance rate is incredibly low. It was mentioned that the previous year's exam, in which Izuku Midoriya and Katsuki Bakugo participated, had a pass rate of less than 0.02%.

Despite this, the academy allows students to enter through recommendations, either because they are the children of a professional hero, as in the case of Shoto Todoroki, or because they belong to a famous and influential family, as in the case of Momo Yaoyorozu. Those admitted through recommendations also take a practical exam, though not as challenging as those for other applicants, and a personal interview.

School Traditions: The UA Academy student uniform consists of a long-sleeved, button-down white shirt, a gray blazer with teal stripes, and a red tie. The boys' uniform includes dark teal trousers, while the girls' uniform includes a dark teal skirt.

The sports uniform consists of dark blue trousers with white vertical stripes running up the legs and a dark blue short-sleeved shirt with white stripes forming the letters 'U' and 'A'. The winter version of the gym uniform consists of a long-sleeved shirt.

Nemuri Kayama (Midnight): Shota Aizawa (Eraserhead) and Nemuri Kayama (Midnight) maintain a close and solid friendship that began during their student years at U.A. High School and continued through their time as colleagues and teachers at the same institution. Despite their contrasting personalities—Nemuri's enthusiastic and extroverted attitude versus Shota's serious and reserved nature—they get along very well and have a great deal of professional trust in each other. Aizawa respects her judgment, even asking for her help with his classes when he deems it necessary.

Toshinori Yagi (All Might): Shota Aizawa and Toshinori Yagi (All Might) maintain a professional relationship as colleagues and teachers at UA Academy, based on mutual respect, although with friction due to their opposing views on teaching and the role of heroes.

Hitoshi Shinso: The relationship between Shota Aizawa (Eraser Head) and Hitoshi Shinso from My Hero Academia is that of mentor and disciple.
Secret Mentorship: Aizawa notices Shinso during the U.A. Sports Festival. He observes that Shinso's Quirk (Brainwashing) is ineffective against unresponsive objects or villains, much like his own. He decides to secretly train him before he enters the hero course.
Combat style: Aizawa teaches him to use the capture bandages (special alloy scarf), which allows Shinso to defend himself in close combat when his Quirk doesn't work.
Dynamics and personality: Both share a calm, serious, analytical personality and a tired appearance with dark circles under their eyes. This has led fans to create theories and memes about a father-son relationship, although in the official storyline it is strictly professional and based on academic respect.
Institutional support: Thanks to Aizawa's guidance, Shinso manages to improve his skills and transfer to the Heroism Department in his second year.
