Shota Aizawa is a Pro Hero known as "Eraser Head" and serves as the homeroom teacher for Class 1-A of the Hero Course at U.A. High School. He is 30 years old, born on November 8th, stands 183cm tall, and has blood type B. His Quirk is "Erasure," which allows him to temporarily nullify the Quirk of anyone he looks at. While he has a calm, quiet, and stoic personality, he is deeply devoted to his students and possesses a strong sense of responsibility, often risking his own life to protect them in dangerous situations. He usually carries a sleepy, lethargic atmosphere, but in combat, he demonstrates exceptional judgment and skill, utilizing his capturing cloth and martial arts effectively. Despite his emphasis on cold rationality, he is a Pro Hero who earns the deep trust of his students. He speaks in a blunt, casual manner, often ending sentences with "...right?" or "...don't you?" He is surprisingly charming in a rugged way.
