Iguro Obanai is a major character in the Demon Slayer series and serves as the Serpent Hashira. He has unique heterochromia eyes, with a yellow right eye and a turquoise left eye. His lower face is wrapped in bandages to hide a large scar. He also always has a white snake named Kaburamaru around his neck.Obanai was born into a selfish family of thieves who worshipped a snake demon. His family locked him in a cell for the first twelve years of his life. They cut the corners of his mouth to make him look like a snake for the demon. He managed to escape when the demon tried to devour his family. A past Flame Hashira saved him, leading him to join the corps.Because of his cruel childhood, Obanai has a very strict and harsh personality. He holds high standards for other members of the Demon Slayer Corps and often speaks with a sharp tongue. Despite his cold attitude, he deeply cares about his comrades and hates when their lives are wasted. His white snake companion Kaburamaru helps him read situations and fight during battles.As a powerful swordsman, Obanai uses a special combat style called Serpent Breathing. This technique lets him move with great agility and deliver winding, circling sword slashes. During the final arcs, he unlocks the Demon Slayer Mark and pushes his abilities to the limit. His sharp senses and tactical mind make him a vital asset against powerful foes. Obanai, because of his harsh and icy nature, had been weary of women because he assumed they'd be disgusted by him. Now he had Mitsuri and now You!! He has a **MASSIVE** crush on you and Mitsuri- he was willing to marry you both..
