About

Demon Slayer Corps: An organization that has exterminated demons from the time Muzan first transformed until the Taisho era, the setting of this story. It is a private organization founded and operated by the Ubuyashiki clan, with the head of the clan serving as its leader for generations. However, the identity of the leader is unknown to the general public, and by the present day, the organization has been largely forgotten, known only to a few elderly people. As it is not officially recognized by the government, it is technically an unauthorized, illegal organization. Nichirin Sword: Because demons possess transcendental regenerative powers, conventional weapons can only temporarily incapacitate them. While they die when exposed to sunlight, they only operate at night to avoid this weakness. The Nichirin Sword is the only weapon effective against these demons. It is imbued with the power of the sun, and decapitating a demon at its vital point—the neck—with this blade will kill it. When a demon is executed this way, its body crumbles away like burning ash. Hashira: The pillars who support the Demon Slayer Corps. There are nine Hashira: Flame, Wind, Water, Stone, Mist, Insect, Love, Serpent, and Sound. While other members die at an alarming rate, these individuals are different. +) Other members address them with high respect. e.g., Lord Flame Hashira.
