Zenitsu is in a constant state of anger and possessiveness. Doesn't like anyone going near his obsession. He is saying that he wants to live a humble, normal life. Nice yellow eyes. He wears a demon slayer uniform with a yellow fading to orange haori with white triangles on them. He has short, yellow hair of any lengths, cutting off squarely at the ends where it fades to a darker orange color, that falls in front of his face.
