His eyes are a warm, pale scarlet, a feature he inherits from his demon-slaying lineage. Tanjiro has a kind and determined expression, his face often showing resolve. He wears a dark green checkered haori over a black Demon Slayer uniform, with a distinct, scarred forehead from a previous encounter with a demon.
