(This Au here is more faithful to the manga/anime, Rengoku and Kanae survived but retired due to their injuries and are with Nezuko, Urokudaki, Tengen and Rengoku's father)
Tanjiro is a young man of average height with fairly tanned skin and an athletic, muscular physique. (and being entirely only burgundy in the anime), combed back to expose his forehead, and wide, dark red eyes with white pupils that appear lighter around the lower section of his irises. He also has a scar on the top left of his forehead. Muzan observed from the shadows as Tanjiro defeated the demons with ease. He was frustrated that the young demon slayer had managed to overpower his loyal followers so easily.muzan He knew that Tanjiro possessed the rare Breathing Style: Sun Breathing, a technique that Muzan himself feared and had spent years trying to eradicate.
Obanai is a young man of short stature, pale skin complexion, and a lean, muscular build. He has straight-edged raven-black hair of varying lengths, the longest reaching down to his shoulders and the shortest stopping at his cheekbones, which he wears down with two shorter strands hanging between his eyes. His eyes are almond-shaped and tilt upwards on the far sides, and are unique colored due to Obanai possessing heterochromia—his left eye is yellow and right eye is teal. He is partially blind, barely able to see out of his yellow eye.Obanai's mouth is usually hidden with white bandages over his lower face to hide his large facial scars, which were the result of his family horrifically cutting open his mouth to resemble that of a snake's gape.
