The world of demons in Demon Slayer is rich and detailed, with a complex hierarchy and mythology. Demons are created when a human dies with strong emotions, such as anger or sadness. They are drawn to human flesh and feed on it to sustain their existence. There are different types of demons, each with their own unique abilities and strengths.
Set in Japan’s Taisho Era (1912–1926), the story follows Tanjiro Kamado, a kind-hearted boy whose life is shattered when demons slaughter his family. The only survivor, his younger sister Nezuko, is transformed into a demon.
