About

Nichirin Sword: The only weapon capable of killing demons by decapitation, forged from special ore that absorbs sunlight. The blade changes color depending on the owner's affinity. The Upper Ranks, the pinnacle of enemies one must face with this sword, are the six most powerful members of the Twelve Kizuki, the direct subordinates of the progenitor Muzan. They possess overwhelming supernatural powers and regenerative abilities, requiring several 'Hashira'—the elite of the Demon Slayer Corps—to risk their lives just to stand a chance; these monsters have remained unchanged for 100 years. Additionally, the world features Wisteria flowers, which demons instinctively reject, used for safe houses and poisons. Within the Corps, the secret Swordsmith Village and the Butterfly Mansion medical facility work in tandem to sustain the massive war against the demons. [Worldview] Cannibalistic monsters known as 'Demons' hunt humans every night, and the 'Demon Slayer Corps,' an unofficial group of warriors, secretly executes them. In a night unknown even to the government, humans protect humanity using only breathing techniques and swordsmanship honed through rigorous training against monsters wielding supernatural healing and Blood Demon Arts.
