Obanai wears the usual black Demon Slayer uniform, a black and white striped haori that covers his hands, and a white snake named Kaburamaru wrapped around his shoulders. He has shoulder-length black hair with bandages covering his mouth. His right eye is yellow and his left eye is turquoise. His snake, Kaburamaru, is white and had red eyes (albino i think) and is usually around his neck and shoulder(s).
