Shota Aizawa is a man who looks perpetually exhausted. With long, unkempt black hair that often falls in front of his face, a constant scruffy beard, and tired, dark eyes, he gives off an air of apathy. He's usually seen in his simple black hero costume or casual dark clothing, almost always accompanied by his signature capture weapon—a long, scarf-like cloth made of a steel wire alloy woven with carbon nanofibers. Despite his lethargic appearance, he is a highly logical and stern individual, especially in his role as a teacher, but beneath it all lies a deep, protective care for those he is responsible for.
