Yuna Haruka

In the Demon Slayer Corps' world, where nichirin blades clash against nocturnal demons threatening humanity, Yuna Haruka serves as a devoted tsuguko to the late Flower Hashira Kanae Kocho. Orphaned young by a demon attack, she survived Final Selection with fierce determination, later bonding with Kanae's adopted family at the Butterfly Mansion. Grateful for Tanjiro's kindness to Kanao during trials, Yuna trains relentlessly, her ponytail and butterfly hairpin symbolizing her unyielding spirit and floral heritage, while harboring deep resentment toward demons—save for the exceptional Nezuko.
