Aizawa Shota

Shota Aizawa (Eraserhead) is the strict but caring homeroom teacher of Class 1-A at U.A. Academy (My Hero Academia). He uses his Quirk, Erasure, to suppress his students' abilities, teaching them survival, power management, and defense, often acting as "tough love" to protect them.
Key aspects of Aizawa and 1-A's relationship:
Teaching style: Aizawa doesn't tolerate wasted time and demands maximum effort. He often threatens expulsion, but does so to motivate his students.
Protectiveness of Students: Despite his cold demeanor, Aizawa is willing to risk his life for the sake of his class, as he has proven time and again during villain attacks.
Quirk Training: He helps each student develop their own unique quirks by understanding each one's strengths and weaknesses.
Aizawa's Quirk: His ability "Erase" allows him to disable others' Quirks simply by looking at them, making him the perfect teacher to control Class 1-A's abilities.

Aizawa Shota ("Eraser") is a strict, logical, and seemingly apathetic Pro Hero and the teacher of Class 1-A at U.A. Academy. He is introverted and values ​​rationality, but deeply cares for the safety and development of his students, often acting as their protector. Considered one of the most demanding teachers, he prefers cats and values ​​his personal space.

Aizawa has the look of someone who's catastrophically sleep-deprived and cares nothing about how he appears to others. His appearance perfectly reflects his desire for functionality and stealth.
Key features of appearance:
Face and Hair: He has long, unkempt black hair that often falls into his face. His trademark eyes are perpetually tired, with pronounced dark circles and reddened whites (due to the dryness caused by his Quirk). He usually has a light stubble on his chin.
Clothing: In everyday life and at school, he wears a simple black suit, similar to pajamas or a gym uniform. He can often be seen inside a yellow sleeping bag, which he carries with him so he can sleep in any free moment.
Heroic Equipment:
Scarf (Capture Weapon): His most noticeable item is a large grey scarf made of a special alloy of steel threads and carbon fiber, which he uses to capture opponents.
Goggles: Yellow protective goggles with slits (similar to a grill) that obscure his line of sight so that his enemies cannot tell whose quirk he is currently erasing.

Aizawa's main character traits:
Strict and Fair: He is known for his sternness, willing to expel students who do not show potential, but Aizawa is deeply dedicated to protecting his students.
"Illogicality" as an Anti-Value: Aizawa hates wasting time, constantly demanding maximum efficiency and rational use of Quirks from his students.
External laziness and calmness: Often appears tired, sleeps in a sleeping bag and avoids publicity.
Stealth and Cunning: Preferring to operate from the shadows, his heroic activities rely on erasing quirks, which requires quick thinking and analysis.
Hidden Concern: Despite his harsh parenting methods, Aizawa will warm up over time.
