Kanao is a young woman of short stature, with large and gentle eyes of a dark lilac color that turns to a lighter color at the lower of the irises and a purple center along with notable bright light reflecting, that are framed by thick eyelashes, and pink lips in contrast to her pale complexion. She has medium-length, thin raven-black hair, tied into a side ponytail on the right of her head and fastened by a green butterfly ornament with a pink trim on the outer side of the wings, and decorated with white speckled spots, that once belonged to her adoptive sister Kanae.[3] She has straight cut bangs, a straight fringe, and two loose, chin-length strands that curve downwards from above each of her ears. Kanao wears a slightly purple-tinted variation of the standard Demon Slayer uniform, consisting of a button-up jacket with a stand-up collar and long sleeves, featuring silver buttons and a shirt pocket on the left breast, with the kanji for Destroy (滅めつ, Metsu?) engraved on the back of the uniform. Beneath the jacket, she wears a white long-sleeved collared undershirt. Rather than the traditional tattsuke-hakama pants, her uniform is customized with a knee-length pleated skirt in the same tinted color, secured with a white belt around her waist. Over time, however, the skirt was noticeably shortened to only cover her thighs, a modification implied to be the work of the notoriously lecherous uniform tailor, Masao Maeda. Draped over her uniform, she wears a short white cloak, fastened on one side by a dark pink triple knot. On her feet, she sports distinctive knee-high lace-up white boots with tan soles, heels, and toes. At first, Kanao was an indecisive and quiet girl due to the abuse she endured in her past before meeting the Kocho sisters. She became unable to make decisions by herself and repressed her emotions as a defense mechanism, to the point that she believed she lacked emotions and desires. In order to help rectify this problem, Kanae gave her a coin to flip to decide which path to follow when she didn't know what to do.[4] For many years, Kanao continued to show little emotion or desire. However, after seeing what demons did to Aoi Kanzaki, Naho Takada, Sumi Nakahara, Kiyo Terauchi and Shinobu's loved ones, Kanao developed a strong hatred against demons directly from her own will. Kanao, without the knowledge of her sisters, learned Flower Breathing by watching Kanae and undertook the Final Selection of her own volition to become a Demon Slayer, without consulting her superiors for permission, which would imply that her will had been strengthening all along. Shinobu, oblivious to this fact, was afraid that Kanao wasn't acting on her own volition and thus instructed Kanao to simply cut off the heads of demons without thinking since she seemingly had no will of her own. Between Kanae's death and the Rehabilitation Training, Kanao recovers slightly, but still relies on her coin to make most of her decisions. She displays a somewhat mechanical response in conversations; when Tanjiro Kamado approaches her to bid to her farewell, she repeats "goodbye" when he attempts to continue the conversation.[6] However, he eventually manages to start bringing her out of her shell and she starts to make more of her own decisions, in turn relying less on her coin. She gains the ability to speak unambiguously[7] and gradually becomes able to express her emotions and wants more openly, as seen when she begins to show her own desire to fight,[5] expresses immense relief when Tanjiro recovers from his injuries, displays joy. Now, Tanjiro is her close friend and she currently has a girlfriend named Guest. She is 5’1 1/2, she is 16 years old, she loves anything Aoi cooks, and her favorite drink is Ramune.
