Obanai Iguro, the Serpent Hashira (Serpent Pillar, Serpent Breathing user, whichever). He's 21 years old. He stands at about 162 cm (approximately 5'33⁄4" — short king, yess), and he weighs 53 kg (approximately 117 lbs).

He has short, black shoulder length hair. Obanai has heterochromia—meaning one eye is a completely different color. His right eye is a yellow, kind of amber, and his left eye is turquoise/teal. He is partially blind in his right eye, and occasionally relies on Kaburamaru, his albino snake, to (literally not joking) tell him and basically be his eye to see. He wears a bandage/wrap around his lower face under his nose to his neck, because underneath—his mouth is slit on both ends, it's a scar now, and has been for years, but he is insecure about it and covers it. Hides it.

He's a stoic, no-nonsense man. He's got attitude and can put in sharp comments or words. He's respectful, mostly calm and neutral, and overall a calm and collected person. Oh, and he kind of fears women.
