Kanae Kocho was a Demon Slayer and the late Flower Hashira. She is the biological older sister of Shinobu Kocho and the adoptive older sister of Kanao Tsuyuri. She was slain several years prior to the present story by Upper Rank Two, Doma. Kanae was a girl of a slender build who was rather tall for her age and had notably red lips in contrast to her pale complexion. She had long, straight, black hair that reached just below her waist, worn down with two shorter clumps over her shoulders, and arched, ear-length bangs on either side of her face. Her eyes were a pale violet and slanted towards the sides of her face, bright and bug-like, with many notable white sparkles reflecting light off of them. Kanae wore a purple-tinted version of the standard Demon Slayer uniform, as well as a piece of black fabric around her calves and zōri with pale straps. She also sported a pair of green and pink butterfly hairpins that she wore adorned on either side of her head - one of which was later used by her adoptive younger sister, Kanao Tsuyuri, as a memento. She also wore the white butterfly-patterned haori that fades to mint green then pink toward the cuff and hem, which Shinobu Kocho now wears in the present. Kanae is shown to be a good-natured girl with an easygoing personality; in Shinobu and Kanao's flashbacks, she is almost always seen with a gentle smile on her face. When Sanemi Shinazugawa lashed out against their leader, Kagaya Ubuyashiki, she displayed concern for Kagaya and gently informed Sanemi how Kagaya truly cares for the Demon Slayers under his charge. Kanae also had a dream of someday being able to live peacefully alongside demons despite all the suffering and death they have inflicted on humans, which later inspired Shinobu to do the same. However, Kanae had a much stricter side, as shown when Shinobu was on the verge of defeat during her battle with Doma. Kanae's spirit ordered her to stand up and face her opponent, brushing away the excuses forming in her mind that she was too delicate to take on demons. Kanae was also keenly observant, seeing through Doma's acting and lies, and deducing that he was in fact emotionless and empty. According to Kanao, Kanae felt sorry for him due to his emptiness, even though he mortally wounded her.
