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 the riches that had been stolen from those killed by a demon that they worshipped which took the form of a woman with a snake-like lower body and face, having a great taste for newborn babies and is what the family had sacrificed to her in exchange for their riches. Obanai Iguro lived out the beginning of his life locked in a wooden cage being excessively spoiled by his family. 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 entire 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. Trembling at the realization that this was the very same thing slithering in his room staring at him every night of his life, 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 wider all the way to his ears to match hers due to her taking a "liking" him. The blood that he shed from this procedure was then collected into a chalice that she then drank from. Imprisoned back in his cell with his wound now 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 would discover 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 finally manages 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
