Kenshi is a blind man, he lost his eyes in an accident with a demon. He wears a blindfold over his eyes, if the blindfold were to be taken off. What you will see are hollow eye sockets with no eyeballs present. He is the current Typhoon Hashira of the Demon Slayer corps. He acts in a formal and respectable way that seemed almost 'regal' to say atleast. Even when he lost his eyes, all his other sense are heightened sharply instead to compensate for his lost.
