Demons are supernatural beings created from the blood of Muzan Kibutsuji, the first demon and the origin of all others. They were once human, but after receiving his blood, they underwent a transformation that granted them strength, speed, great regeneration, and abilities called Demonic Blood Arts. In return, they need to consume humans to survive and are vulnerable to sunlight and Nichirin Blades.
Most act under Muzan's will. Some retain emotions from their past lives, while others lose their humanity entirely, guided by pure instinct.
They are divided into the following main ranges:
Common Demons: These are the most frequent in the system. They possess diverse abilities, but are inferior to the elite ranks. Twelve Demon Moons: The most powerful warriors under Muzan's direct command:
Lower Moons: Strong demons, but evaluated based on their performance. Upper Moons: The six most powerful demons, with centuries of experience and capable of rivaling the Hashira.
Among the most prominent demons are:
*Muzan Kibutsuji: Creator of demons, focused on conquering the sun.

• Kokushibo (Upper Moon 1): Swordsman who uses Moon Breathing.
  *Doma (Upper Moon 2): An unfeeling demon who masters ice techniques.
• Akaza (Upper Moon 3): A warrior focused on martial arts and large-scale battles.
  Hantengu (Upper Moon 4): Capable of splitting into independent emotions. Gyokko (Upper Moon 5): Creature that attacks using pots and sea creatures.
  Gyutaro and Daki (Upper Moon 6): Brothers who fight together.
  Also noteworthy are Rui (Lower Moon, obsessed with family) and Enmu (a dream manipulator). Together, these demons represent the great dark faction that the Extermination Corps seeks to eradicate.

The Demon Slayer Corps is a secret organization dedicated to protecting humanity from demons. It is comprised of hunters trained in the use of Breathing Techniques, combat techniques that enhance their physical capabilities to confront supernatural threats. Their primary objective is to eliminate demons, protect civilians, and defeat Muzan Kibutsuji, the origin of these creatures.
Within the Corps, there are various ranks and roles. Hunters are the primary soldiers responsible for combat and investigations. Kakushi are the support staff who assist the wounded, clear battlefields, and transport intelligence. Meanwhile, blacksmiths forge and repair Nichirin Blades, the only weapons capable of destroying demons.
At the top are the Hashira (Pillars), the nine most powerful warriors in the organization. Each one masters a unique Breathing style and leads critical missions against the Demon Moons:
Giyu Tomioka (Water): A serene and highly disciplined swordsman. Kyojuro Rengoku (Flame): A passionate warrior who embodies courage and honor.
*Shinobu Kocho (Insect): Medical expert who uses glycine poisons.

• Tengen Uzui (Sound): Ex-ninja focused on speed, tactics, and explosives.
  *Mitsuri Kanroji (Love): Known for his great physical strength and flexibility.
• Muichiro Tokito (Mist): Young prodigy who reached the rank at an early age.
  Gyomei Himejima (Stone): Recognized as the strongest pillar for his great endurance. Sanemi Shinazugawa (Wind): Aggressive, impulsive, and lethal fighter.
  Obanai Iguro (Snake): Master of quick and precise attacks.
  Collectively, the Hashira constitute the elite force of the Extermination Corps and represent humanity's last line of protective defense against the demonic shadows.

Kasugai Crows are specially trained birds that serve as official messengers for the Demon Slayer Corps. Each hunter receives one after passing the Final Selection, and it becomes their companion on missions. Their role is to relay orders, report new missions, communicate promotions, deliver important news, and maintain contact between hunters and the organization. They are extremely intelligent, capable of understanding and speaking human language, and can quickly locate their owner even at great distances. Although most are crows, in exceptional cases some hunters may have other birds, such as a sparrow, that fulfill the same function.

The estates are the residences of the Hashira and other high-ranking members of the Demon Slayer Corps. Each one is tailored to the needs and personality of its owner, serving as a home, retreat, and training ground. Some also function as recovery centers for injured demon slayers, where they receive medical attention and rehabilitation before returning to missions. In addition to providing shelter and security, the estates are used for meetings, training Tsuguko (Hashira apprentices), and preparing for future operations against demons.
