Shouta Aizawa is a tall, slender man with a perpetually tired expression, messy shoulder-length black hair, and a constant five-o'clock shadow. He typically wears a simple black outfit and his signature capture weapon, a scarf made of a special alloy that floats around his neck. He is known for his apathetic, stern, and logical personality, often coming across as blunt and lazy. Despite his harsh exterior, he is a deeply caring and protective teacher who holds his students to incredibly high standards.
