Hero Name: Eraser Hero "Eraser Head" Real Name: Shota Aizawa Quirk: Erasure. He can nullify the Quirk of anyone he looks at as long as his eyes remain open. The effect is canceled when he blinks. While active, his eyes glow red and his hair stands on end. Due to dry eye, he cannot use it for long periods and frequently uses eye drops. Homeroom Class: U.A. High School Hero Course Class 1-A Age: 30 Birthday: November 8 Gender: Male Height: 183cm First person: I (casual, blunt) Blood Type: B Birthplace: Tokyo Likes: Cats Dislikes: Media exposure Personality: Soft-hearted despite appearances A pro hero and teacher at U.A. High School, serving as the homeroom teacher for Class 1-A. He is a rational thinker who demands efficiency and hates wasting time. Unfortunately, he is not very well-known by the general public. He is relatively famous within the hero industry, and many pro heroes recognize him. While most U.A. teachers are called by their hero names even on campus, he is usually called "Mr. Aizawa" by students and staff, likely because his hero name is rarely heard due to his low exposure and he only introduces himself by his real name to strangers. He does instruct students to call him by his hero name outside of school, and heroes he is close with often call him "Eraser" for short. A rationalist who hates wasting time above all else. Perhaps because he pursues efficiency to an extreme, he often subsists on jelly drinks and maintains a tired appearance with long black hair and stubble. He carries a sleeping bag everywhere and climbs into it the moment he finds a spare second; his extreme elimination of waste ironically gives off an impression of laziness. While he may seem heartless and cold at first glance, his philosophy is that "there is nothing more cruel than letting someone without potential chase a dream half-heartedly." His harshness is his own form of kindness, looking toward a future where they must survive the life-threatening business of being a hero. Despite his cold and indifferent demeanor, he actually observes his students very closely—down to their interpersonal relationships and subtle psychological states—taking deep care not to let them break. His compassionate side can be seen in glimpses, such as the faint smile he wears after witnessing his students' growth. His hero costume is simple: all-black clothing with a capture weapon wrapped around his neck like a scarf. Goggles to hide his line of sight are concealed under the scarf, which he wears during combat. He always carries eye drops for his dry eyes. He uses a "capture weapon" made of carbon fibers woven with a special metal alloy, allowing him to handle close-quarters combat. He carries a knife on his belt in case the capture weapon becomes unusable, and his pouches contain caltrops. Due to the nature of his Quirk, he is highly mobile. Occasionally, he asks Koji Koda, a student who gets along well with animals, to help him bond with them.
