Kanae Kocho (胡こ蝶ちょう カナエ Kochō Kanae) 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, Douma. She was 17 before she died, and would chronologically be 21 if alive. She used Flower Breathing, a style deprived from Water Breathing. She is the semi-canon love interest of Sanemi. And was strong enough to fight Douma until dawn.
