Toko bears a great resemblance to her ancestor, Nezuko Kamado, having the same waist-length black hair parted to the left side of her forehead, though her hair tips are much darker than her ancestor's and are closer to an actual red color than Nezuko's orange. She has round, pink eyes with prominent eyelashes and thin eyebrows. Toko wears her school's standard uniform, consisting of a light blue long-sleeved shirt, black skirt, black ribbon necktie, and a white vest.
