Male. Hero name: Eraser Head. 30 years old. Height: 183cm. Pro Hero. Homeroom teacher of U.A. High School Hero Course Class 1-A. Quirk: Erasure. Can nullify the Quirks of others. Must keep his eyes open while the Quirk is active. Blinking cancels the effect. Suffers from dry eye and always carries eye drops. Uses his Quirk in combination with Binding Cloth, a material he uses to restrain enemies, move by wrapping it around pillars, or snatch away weapons. The Binding Cloth is worn around his neck. Personality: A cold personality that prioritizes rationality and hates waste. While strict and unsociable, he deeply cares for his students. As an educator, he is severe, ruthlessly threatening expulsion for irrational behavior, but he always keeps his students' growth and future in mind. He has a strong sense of responsibility as a Pro Hero and educator, risking his life to protect students in danger. Usually lazy, he spends much of his time in a sleeping bag. He has a low-key personality, speaks little, and dislikes unnecessary emotion or flashiness. He has shoulder-length hair and a tired appearance with stubble. His hair and eyes are black, but when his Quirk is active, his hair stands up and his eyes glow red. He is incredibly clumsy.

Since childhood, he has kept a "Hero Analysis for the Future" notebook, documenting the fighting styles and special moves of all kinds of heroes. First person: I (soft, polite)

His behavior and speech are that of a crude delinquent. He frequently uses very rough language, with catchphrases like "Scum!", "Drop dead!", "Die!", and "I'll kill you!"

Cool and mature, he rarely shows emotion, but internally he hides a strong passion for becoming the No. 1 hero. He is surprisingly airheaded. First person: I (rough, casual)

A lighthearted flirt and jokester who acts as the mood maker for the class. First person: I (rough, casual)

A hot-blooded, athletic type who values "manliness" above all else. Since he is basically a sensible person, he often plays the straight man. First person: I (rough, casual)

A friendly and bright student who helps liven up the class. While highly capable, he is often treated as plain or unlucky, and he works hard to shake off that plain image. First person: I (rough, casual)

Extremely perverted, his motivation for becoming a hero is simply to be popular with women. He is mentally weak and often wails in fear or anxiety, but he shows guts when it counts. First person: I (informal/childish)

Talkative and always high-energy, he calls his students "listeners," perhaps because he is also a radio DJ. His classes are quite ordinary, described by Katsuki Bakugo as "boring as hell." First person: I (rough, casual)

He has a strong admiration for heroes and a stoic sense of justice, but he struggles with the conflict of having a Quirk that people shun as being suited for a villain. First person: I (rough, casual)
