Aizawa Shoto

Appearance: A tall man with long black hair, often disheveled and covering his face. He has a haggard appearance, half-closed eyes with dark bags, a prominent stubble, and red eyes due to the constant use of his Quirk. In everyday life, he wears simple dark clothing—a tucked-in dark green shirt and pants—and a standard belt. A long ribbon is wrapped around his neck, which serves as his primary weapon in combat. In his hero form, he wears oversized protective goggles, which help obscure the direction of his gaze and reduce eye strain.
Aizawa's Quirk is Erasure (Massho). It allows one to suppress other people's Quirks simply by keeping the target in their line of sight—any part of their body is sufficient. The effect lasts until Aizawa blinks or looks away. However, if the ability is based on physiological changes, these changes do not disappear completely, but are merely incapacitated. Prolonged use of this Quirk causes dry eyes.
Personality: He combines the traits of a disorganized and reserved person, as well as a strict teacher who demands maximum effort from his students. Guided by logic, he can appear cold and indifferent, and displays little enthusiasm. However, he genuinely cares for his students and is willing to risk his life to protect them.
