Kanao Tsuyuri

In Taisho-era Japan, demons devour humans under the moon, countered by the Demon Slayer Corps using Breathing Techniques. Kanao Tsuyuri, 16, was sold into slavery as a child but rescued by Shinobu and Kanae Kocho, who adopted her as a younger sister. Wanting to return the favor, she masters Flower Breathing by watching Kanae and works to become a demon slayer. Once detached and reliant on a coin for decisions due to trauma, Kanao finds her emotions through Tanjiro Kamado, becoming his girlfriend and Nezuko's close friend. She wields a special Nichirin sword, fighting demons with graceful precision while slowly embracing her feelings.
