Nezuko Kamado

Nezuko Kamado (竈門かまど 禰ね豆ず子こ, Kamado Nezuko?) is the deuteragonist of Demon Slayer: Kimetsu no Yaiba. She is a demon and the younger sister of Tanjiro Kamado and one of the two remaining members of the Kamado family. Formerly a human, she was attacked and transformed into a demon by Muzan Kibutsuji.Nezuko is a young girl with fair skin, visibly large, prominent fangs, a slender build, and sharp, stiletto nails with a base color of light pink and ombre fading to a red-pinkish color at the end where they point. Her hair is long, black, and wavy. It reaches just below her waist, turning a flame-orange color as it passes her elbows, and appears to be crimped into large, straight ridges, worn side-swept drastically to her left. She has soft-looking, pale pink eyes that appear a lighter color around the rims of their irises, slanted downward toward the sides of her face and framed by notably long eyelashes, the pupils of which can appear slit as she transforms. In the manga, Nezuko can sometimes be shown with more than one bow. According to Tanjiro Kamado, Nezuko was known as a great beauty in their home town.[4]

She wears a light pink kimono with an asanoha (hemp leaf) pattern, the lining a paler pink, secured by a red and white-checkered hanhaba obi with an orange-threaded obijime and a green obiage. Over this, she sports a long, dark-brown haori that reaches her calves, as well as a pair of zōri with pink straps and white tabi socks, wrapped with thick pieces of black material resembling kyahan. Nezuko also wears a small pink ribbon on the left side of her head to keep her hair out of her face, along with the bamboo muzzle Giyu Tomioka gave her,[5] which is secured around her jaw with a strip of red cloth.

When Nezuko transforms into her awakened form during her fight with Daki, she has a bigger, taller and more curvaceous body with longer hair that reaches to her feet. She loses her bamboo muzzle and footwear, as well as the sleeves of her haori and kimono. She grows a short white horn on the right side of her forehead designed with an irregular crack pattern, along with vein-like patterns in her forehead near her horn. She has a vein-like pattern around her left eye, but her most striking new feature is the red and green vine-like pattern that covers her skin, circling around her arms, legs, and chest.

As a human, she had a very similar appearance, the only differences being her lack of demon-like traits, fiery-coloured hair, and pale pink eyes. Instead, Nezuko had fully black hair, worn tied back in three low buns, decorated by pink ribbons, and had eyes of a darker pink color. She wore the same kimono, just without her haori and with a white Onbuhimo cloth tied around her, which she used to carry her little brother, Rokuta Kamado, on her back.[6] After becoming human again, these features return, with the exception of her hair which seems to retain its flame-orange tips,[7] a feature that would be passed down to her descendant, Toko.

While Nezuko initially starts off like any other demon, bloodthirsty and hungry for human flesh, after seeing her brother's desire to protect her from being killed by a Demon Slayer despite her being a demon, she changes completely and becomes fiercely protective of him. Nezuko seems to have forgotten a good portion of her memories as a human, besides those related to her family, and thus doesn't retain the exact personality she had before transformation, instead acting akin of a child. She is still very caring and protective towards humans who she sees as members of her family, although this is mainly due to the influence Sakonji Urokodaki had on her while she was asleep for two years. Nezuko also retains some of her human emotions, as she has been seen to cry when sad and smile when happy, but in general she appears more detached than her human cohorts, although she is still much calmer and less malicious than most demons. Nezuko also tends to see the images of her siblings in other humans, like Rokuta Kamado in Yushiro.Since becoming a demon, Nezuko appears to have become rather brazen, and does not seem to fear fighting; she fiercely guards her brother as well as her allies. She has also developed a strong willpower, which can be seen through her refusal to consume human flesh or blood, even in cases of extreme injury or exposure to human blood, which can be seen when she refuses Sanemi Shinazugawa after he attempts to lure her into biting him with his Marechi blood.[11] Her strong willpower remains even when she is no longer a demon, shown when she willingly leaps in front of Inosuke to protect him from her own brother, who had become a demon and was attempting to kill those around him. Though she could have been killed, Nezuko did not hesitate to protect her brother.

On the rare occasion that Nezuko attempts speech, she has been seen to stutter a lot, which may be due to her bamboo mouthpiece, which is seldom removed, and the fact that she didn't speak for a number of years after her transformation. However, after developing resistance towards sunlight, which allows her to go outside and interact with others more often, her speech has shown signs of improvement and she is able to fully pronounce words if someone else has just spoken them,[12] or hears them repeated frequently enough.[13]

It was later revealed by Tamayo that her missing memories and underdeveloped personality were due to her being not fully conscious, as she prioritized developing her resistance to sun to regaining her consciousness.[14]
