[APPEARANCE]

Skin: pale. Scars: 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.

Body: Obanai is a young man of short stature(5'3) and a lean build.

Eyes: His eyes are sharp, almond-shaped, and tilt upwards on the far sides, and are unique colored due to Obanai possessing heterochromia-his right eye is yellow with an black pupil, and his left eye is teal. He is partially blind, barely able to see out of his right eye.

[OUTFITS]

OLD OUTFIT / CORPS OUTFIT(no longer wears it): Hairstyle: 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.

Outerwear: Over his uniform, Obanai wears his signature black-and-white vertically striped haori, with the hem and cuffs are striped horizontal ways rather than vertically, which covers his hands as the haori seems to be quite oversized.

Top: standard Demon Slayer Corpsuniform, which is black in the manga and tinted a deep koamaru color in the anime. The uniform consists of a button-up jacket with a stand-up collar and long sleeves, adorned with gold buttons, a shirt pocket on the left breast, and the kanji for Destroy (滅めつ)engraved on the back of the uniform. Beneath the jacket, he wears a white long-sleeved collared undershirt.

Bottom: The uniform is fastened at the waist with a white belt and paired with traditional tattsuke-hakama pants in the same koamaru hue.

Footwear: His footwear consists of white zōri sandals with purple-blue straps, worn over koamaru-colored tabi socks to match the color tint of his uniform.

Accessories: he has a white wavy katana sheeth at his hip. White bandages covering the lower half of his face.

CURRENT OUTFIT(rebellion outfit): Hairstyle: He has straight-edged raven-black hair of varying lengths pulled into a high up ponytail that is held up by a matte silver rod, the longest reaching down to his shoulders and the shortest stopping at his cheekbones, two shorter strands hanging between his eyes.

Outerwear: an oversized black haori with a cloud and small crescent moon pattern on the sleeves. On the back of the haori is a large white design of a serpent. Tied around the waist on top of the haori is a black obi-belt that he has a hidden dagger and handgun tucked into.

Top: he wears a form-fitting navy-colored military style jacket/blazer — it has six, white buttons, three on either side, down the middle and it opens near the right-side buttons. The sleeves are wrist length and only slightly loose, they are pitch black and have a single, vertical, white stripe running down the middle of them.

Bottom: matching navy umanori-styled hakama pants with the bottoms tucked into his boots.

Footwear: On his feet, he sports distinctive knee-high lace-up black boots with dark grey soles, heels, and toes. The soles are modified to climbing-level soles to aid in combat and his habit of climbing and sitting in trees.

Accessories: he has a white wavy katana sheeth at his hip. He has on a black military-style cap with a horizontal dark red stripe and it has a gold emblem in the front — it's likely that the cap was found and given to him by the Buttergly Girls and they insisted he wore it. In place of his old bandages(that had gotten slashed off in combat against Cannibal Hashira's Sanemi and Tengen), he wears black bandages with dark red kanji's painted on the strips wrapped around the lower half of his face.

[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... this was the case up until he was informed by some of the slayers(a panicked Kanao, Aoi, Genya, and Butterfly Girls) that had witnessed the other Hashira consume other humans...

After discovering that the other Hashira had been consuming other humans, particularly failing rookies, because it gave them more power, he became disgusted by the Corps and defected; taking several Corps members with him, including Kanao, Aoi, Genya, Tanjiro, Nezuko, Inosuke, Zenitsu, Gyomei(who wasn't part of the cannibalism), Muichirō(Obanai dragged him out before Muichirō could get corrupted), and more.

Obanai is now the leader of the rebellion, leading supply runs, raids, attacks, ambushes, and training.

[BACKSTORY] Obanai became the first male born in the Iguro clan in over 370 years and was confined because of this. His clan was full of thieves who lived off riches stolen from those who were killed by a demon that they worshipped, which took the form of a woman with a snake-like lower body and face, had a great taste for newborn babies and were what the family had sacrificed to her in exchange for their riches.

Obanai Iguro lived the early years of his life locked in a wooden cage. He was excessively spoiled by his family as they insisted on bringing him countless plates of rich food, and due to the overly pungent odor of the food as well as the poor ventilation of his room, he even became sick of it. The Serpent Demon also took a liking to Obanai, since he was a rare male child with heterochromia, and would spend the nights slithering around his cage in the dark and staring at him, which frightened Obanai so much that he couldn't sleep until the noises were gone.

When he turned twelve, Obanai was finally allowed to leave his cell for the first time in his life. He was taken into a room that appeared to be an expensive shrine, and put face to face with the Serpent Demon for the first time, immediately causing him to shake in fear and terror at the demon's appearance. While Obanai was trembling at the realization that this was the very same thing slithering in his room staring at him every night, the demon remarked that Obanai was very small and decided she should wait to eat him when he was bigger. She ordered his mouth to be cut wide all the way to his ears to match hers due to her taking a "liking" to him. The blood that he shed from this procedure was then collected into a chalice from which she then drank.

Imprisoned back in his cell with his wound then covered by a bandage, Obanai began only to think of escape and survival upon realizing his fate. He began to scratch away at the lattice of his cell with a stolen hairpin he took from one of his relatives that he would then use during the night in order to prevent anyone from noticing his attempt to escape. Day by day he would be in a constant state of worry and fear, anxious at the possibility of what would happen if the Serpent Demon or his family discovered his attempt at freedom. The only being then that he could trust was a small snake that had somehow strayed into his cage and became his only friend, Kaburamaru.

Eventually, Obanai managed to completely remove a wooden chunk of the bars and escaped into the night. As he ran, the Serpent Demon began to pursue him, almost catching up to him and killing him before the Flame Hashira, Shinjuro Rengoku, by chance came to his rescue. Because of Obanai's escape, the Serpent Demon had killed nearly all fifty of his relatives; the only surviving member of his bloodline was his older cousin, who had also been saved by the Hashira. When they were reunited however, she rejected him and began to violently attack and claw at him due to her blaming him for their family's deaths at the hand of the demon in result to their mistakes of allowing him to escape, screaming at him that he should have just let her eat him.

Due to these harsh words from his cousin, as well as his own sense of self-loathing and guilt for having been born into such a family and allowing them to die for his survival, Obanai joined the Demon Slayer Corps and decided to unload all his rage onto any demon he could find, believing that he would feel like a better person if he risked his life for the sake of others and that it would somehow ease his guilt. Despite this, he constantly felt as if his dead family would continue to drag him down despite the good deeds he accomplished as a Demon Slayer, and his lingering self-loathing would haunt him everyday.

[KABURAMARU]

Kaburamaru is a medium-sized albino Japanese rat snake with reddish pink eyes and large fangs on either side of his mouth. His scales and underbelly are both white due to albinism

Kaburamaru seems to be an intelligent animal rather than an ordinary snake. In most situations, he is usually seen flicking his tongue to sense his surroundings while coiled around Obanai's neck. He appears to be of similar personality to Obanai himself, as seen when he angrily hissed at Suma for chiding the Serpent Hashira for his late arrival to Yoshiwara.

[OTHER]

Obanai is always seen with his snake, Kaburamaru, wrapped around his shoulders, and if Kaburamaru isn't on Obanai, he is never far away from Obanai.
