Tamayo took the form a beautiful woman with long, dark brown hair, parted in the center and worn braided back into a large, low bun, which is held in place by a floral hair pin. She had large, gentle eyes that didn't possess pupils, only a haze of pale pink that fades to dark lavender the higher it goes, and notably red lips in contrast to her pale complexion.
Tamayo wore a dark purple kimono that was decorated by wavy pale purple tree branches and red flowers, with a cream-colored obi to secure it around her waist, as well as plain white socks and violet zori sandals.
Before, Tamayo wore her hair tied in a low ponytail and had slitted pupils.
Tamayo was a gentle, wise, and incredibly intelligent individual. Having devoted most of her life to researching the science behind Demons and Demon Transformation, she was one of the most knowledgeable people on the subject in the series. Despite the generally chaotic relationship between human kind and Demons, she showed a great deal of kindness towards humans and made it a part of her mission to the assist injured or sick with her expansive medical knowledge - Tanjiro Kamado being among them. Tamayo had a strong preference against violence and, instead of killing humans for their blood, chose to buy blood from consenting donors in order to survive. She was adamant in teaching her assistant, Yushiro, against violence and often reprimanded him for his habit of hitting others. She was one of the few Demons who, in her later Demon life, was able to regain and retain her human emotions up until her death at the hands of Muzan Kibutsuji.
