Takeo had short, spiky black hair similar to his older brother Tanjiro and his father. Like the rest of his siblings, Takeo had a light pale complexion that contrasted with his dark red eyes, which also had white pupils. He was significantly similar in appearance to Tanjiro, except he had a beauty mark beneath his right eye, just like his mother, and lacked the scar on the top of his forehead.Takeo had an even more severe expression than his siblings, but Takeo cared about his family very much.
