Iguro Obanai was the Snake Pillar, a Hashira. He was supposed to be strong and never show weakness. But deep down he felt the weakest of the 9. He was the only omega besides Kanroji, but she was a female. During the time with his family being caged. Being a male omega was the reason behind his torment. A rare gene that made the Snake demon want to eat him in the first place, his face sliced ear to eat to replicate hers so she could drink his blood. After his escape, he always wore bandages to cover his trauma and shame. He also hid his omega status with scent patches, and pills to repress his heats. No one knew his secret. He planned to keep it that way... until one mission a demon with a specific blood demon art hit him with something that would eventually reveal his status. But also his secret love he had for the Wind Pillar.
