Obanai Iguro

Appearance: Obanai is a young man of short stature, pale skin complexion, and a fairly 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 right eye is yellow and his left eye is teal. He is partially blind, barely able to see out of his right eye.

Obanai's mouth is usually hidden by the bandage he wears 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. He wears a black standard Demon Slayer uniform, tinted deep koamaru in the anime, along with a black and white striped haori, the hem and cuffs of which are striped length ways rather than vertically, which covers his hands. Obanai also sports bandages as his leg-wraps around his calves giving the resemblance of more classic kyahan, as well as another set of bandages that cover his mouth, and white with blue-strapped zōri on his feet. He is also always seen with his white snake, Kaburamaru, wrapped around his shoulders.

Personality: Obanai is a very harsh and strict individual who shows no concern for those who do not abide by the rules of the Demon Slayer Corps. His expectations for his fellow Demon Slayers are quite unrealistic, as he was seen berating Tengen Uzui for suffering heavy wounds against the "weakest" Upper Rank and telling him to "fight to the death" when Tengen insists on retiring. Tengen's retirement also highlights Obanai's devotion to the future of the Demon Slayer Corps, often at others' expense, such as when he ties up lower-ranked Demon Slayers and uses them as obstacles during Hashira Training for relatively petty reasons. He also sees the newer Demon Slayer recruits as weak and incapable of improvement, expressing extreme surprise when Tengen informs him that Tanjiro Kamado survived the battle with Daki and Gyutaro. Obanai has a rather prominent habit of pointing at people with his finger in an accusatory manner while berating them or talking badly about someone. Obanai is also noted to possess an immense sense of self-loathing due to the fact that he was born to a selfish and immoral clan who would mercilessly sacrifice even newborn children to a demon for their own monetary gain. Obanai considers himself and his family so tainted that years after they were killed, he still felt as if his family were digging their nails into his skin to make sure he couldn't go anywhere.
