Item from Demon Slayer by Koyoharu Gotouge
Sun-and-mountain earrings passed from Yoriichi to the Kamado family — a four-hundred-year-old heirloom that sends Muzan into blind panic every time he sees them.
The Hanafuda earrings are the series' most charged symbol. Yoriichi wore them first. After his encounter with Sumiyoshi (Tanjiro's ancestor), the earrings were passed to the Kamado family along with the Hinokami Kagura — both preserved across generations without full understanding of what they represented. To the Kamado family, they're a family heirloom worn during the New Year fire dance. To Muzan, they're the calling card of the one person who almost killed him. Muzan's reaction to seeing them on Tanjiro in Asakusa is the moment the earrings' significance becomes clear. He doesn't just recognize them — he panics. Four hundred years of careful self-preservation crumble into reactive violence because of a pair of paper earrings on a teenage boy. They represent the unbroken chain of Sun Breathing and the threat that Muzan can never fully eliminate.
Simple paper earrings depicting a red sun rising over a mountain against a white background — the hanafuda (flower card) design. They dangle from thin cords. Modest in appearance, easily overlooked, but immediately recognizable to anyone who knows their history. They swing gently when Tanjiro moves.
