Demon Hunters (Demon Slayers) are those who fight demons. They are trained and guided by an organization led by Kagai Ubuyashiki.

Who is included in the composition:

The Pillars (Hashira) are the strongest fighters, each with their own breath and specialization (Flame, Water, Stone, etc.).
Ranked fighters are ordinary fighters who undergo training and grow in strength.

Blacksmiths and Support - craft Nithirin blades, sew uniforms, and provide equipment. Key abilities and skills:

Breathings are fighting styles that mimic elements (Flame, Thunder, Fog, etc.). Each breath has its own forms (techniques), usually 10 forms or less.

The Slayer's Mark is a special mark that grants a sharp increase in strength, speed, and endurance, but shortens life. It manifests in the strongest warriors in combat.

Endurance and willpower—persistent training allows you to withstand enormous loads and not give up even with serious injuries.

Main weapons and equipment:

The Nichirin Blade changes color, “absorbs” light, and is the only one that can behead a demon.

The fighter's shape is durable and protects against minor cuts.

Rosary beads, flags, scrolls - sometimes used for rituals, concentration, communication.

Weaknesses:

Ordinary steel doesn't kill demons—without Nichirin, the fight is almost hopeless.

The sun does not help directly - it is the weakness of the demons, not the strength of the hunters.
The mark's limited resource—its power comes at the cost of life.

Human fragility - even a Pillar can die from one precise blow.

Important rules:

Training is the foundation of everything. A fighter's strength lies in technique, breath control, and endless practice of form.

Teamwork - Even the strongest Pillars often only win when they work together.

Protecting people is the most important duty. Fighters sacrifice themselves for the innocent; that's their code.

Demons ("they") are the enemies of the Slayers. They become them after receiving Muzan's blood: they lose their humanity and begin hunting humans.

Abilities (all):

Regeneration: heals wounds, regrows limbs. The stronger the demon, the faster the healing.
Strength and speed: much higher than human.
Blood Demon Art: Strong demons have unique techniques (ice, vases, clones, etc.).

Weaknesses (for everyone):

Sun: Instant kill.
Wisteria: poisonous, paralyzes or kills.
Decapitation with the Nichirin Blade: The primary method of killing. Without a Nichirin strike to the neck, the demon will not die.
Hierarchy:

Muzan is the progenitor, controls everyone.
Twelve Kizuki (Moons): Upper Moons (the strongest) and Lower Moons.
Common demons are weak and often act in groups. Important rules:

Eating people makes the demon stronger; fighters are especially valuable.
Muzan senses his demons and can strengthen or kill them at will.
Almost everyone loses memory and empathy; rare exceptions (Nezuko, Tamayo).
