Techniques

Beast Breathing is a self-taught swordsmanship style that channels the ferocity and instinct of wild animals. Born in the mountains from a fight for survival, it favors raw, unpredictable strikes delivered through dual blades and a razor-sharp sense of touch.

A Blood Demon Art is a personalized supernatural power that stronger demons develop after consuming enough humans. Each one draws on the demon's own blood as the medium for its effects, and the theme typically reflects that demon's history, character, or former trade.

Breathing Styles are the swordsmanship traditions of the Demon Slayer Corps, each built on the discipline of Total Concentration Breathing. They amplify a fighter's strength, speed, and stamina, and every known style traces its lineage back to the original Sun Breathing.

The Bright Red Nichirin Sword is a temporary transformation that turns a Nichirin blade glowing crimson with special properties. Only slayers whose Demon Slayer Mark has awakened can normally produce it, and it cripples a demon's ability to heal.

The Demon Slayer Mark is a birthmark-like pattern that certain Demon Slayers can awaken under extreme conditions. It dramatically boosts their physical power and unlocks several advanced abilities, but it carries a fatal cost: nearly all who awaken it die before turning twenty-five.

Extrasensory Perception is a heightened sixth sense that lets both demons and Demon Slayers detect things beyond ordinary senses. It powers long-range awareness of nearby presences and sharp combat reading of an opponent's intent to strike.

Flame Breathing is one of the five core swordsmanship styles descended directly from Sun Breathing. It mirrors fire through forceful single strikes that seem to scorch their targets, and for generations the Flame Hashira post was held by members of the Rengoku family.

Flesh Manipulation is a power shared by all demons that lets them reshape and command their own bodies. It ranges from minor involuntary mutations in weak demons to elaborate weapons, clothing, and even fusing with a train in the strongest members of the Twelve Kizuki.

Flower Breathing is a graceful swordsmanship style branched from Water Breathing. It mirrors blossoms and fruit flowers through agile, flowing strikes, and it sharpens the user's vision to extraordinary degrees, though pushing that gift too far risks their eyesight.

Hinokami Kagura, later revealed as the legendary Sun Breathing, is the first and most powerful swordsmanship style ever created. Once disguised as a ceremonial dance passed down the Kamado family, it imitates the sun and gives rise to every other Breathing Style.

Insect Breathing is a poison-driven swordsmanship style branched from Flower Breathing. Rather than beheading demons, it stings them with rapid thrusts from a needle-tipped blade, injecting lethal wisteria-based toxins to make up for the wielder's lack of raw strength.

Love Breathing is an acrobatic swordsmanship style branched from Flame Breathing and built around the feeling of love. It turns the user's extraordinary flexibility and strength into fast, winding slashes, and it is the only style whose creation is shown directly in the story.

Mist Breathing is a swordsmanship style branched from Wind Breathing that mirrors the concealing nature of fog. Its forms revolve around disorienting, hard-to-read movements that leave opponents confused, as if a thick haze had swallowed their vision.

Moon Breathing turns a swordsman into a storm of curving crescent slashes. Built by Michikatsu Tsugikuni after he failed to grasp Sun Breathing, it became the signature style of the demon Kokushibo and ranks among the deadliest sword arts in the series.

The Opening Thread is a perception ability Tanjiro Kamado uses to find a demon's brief opening through scent. It steers his Nichirin blade to the precise angle on the neck needed to behead a demon in a single clean stroke.

Regeneration is a power every demon possesses that lets them heal injuries at incredible speed, from minor cuts to severed limbs and even decapitation. Its strength scales with how much of Muzan's blood a demon has assimilated, making the strongest among them nearly impossible to kill.

Repetitive Action is a discipline a handful of Demon Slayers use to push their bodies past human limits. By cycling through a fixed routine of movement, prayer, or memory, the user climbs to a peak of concentration and unleashes raw strength for an extended stretch.

The Selfless State is an elusive condition regarded as the summit of physical combat. A fighter who reaches it wipes away all fighting spirit, malice, and hunger to win, becoming so still and unremarkable that even keen demons can no longer sense them at all.

Serpent Breathing copies the slithering, sudden strikes of a snake, sending the blade weaving along unpredictable paths. Branched from Water Breathing, it belongs to Obanai Iguro, who wields a curving sword shaped like a snake's body.

Sound Breathing weaponizes noise, pairing blistering speed with anti-demon explosives to overwhelm foes in deafening bursts. Derived from Thunder Breathing, it is the explosive specialty of the flamboyant Hashira Tengen Uzui.

Stone Breathing draws on the weight and solidity of earth, trading nimble swordplay for crushing strikes delivered with massive weapons. One of the five core styles, it is the discipline of Gyomei Himejima, the Stone Hashira.

Thunder Breathing mimics lightning splitting the sky, built around explosive speed and instant, overwhelming strikes. One of the five core styles, it is wielded by Jigoro Kuwajima, the traitor Kaigaku, and Zenitsu Agatsuma.

Total Concentration Breathing is the foundation of every Demon Slayer's strength. By filling the lungs fully and quickening the blood, the user warms their body and pushes muscle and bone into a state of fierce excitement, gaining superhuman power while staying entirely human.

The Transparent World is a rare form of sight unlocked only by Demon Slayers who have awakened the Demon Slayer Mark. It renders other beings see-through, exposing their blood flow, muscle, and joints, which lets the user read movement before it happens and react with uncanny speed.

Water Breathing captures the flow and adaptability of water, bending body and blade in fluid arcs. One of the five core styles and the most common among slayers, its users include Sakonji Urokodaki, Giyu Tomioka, and Tanjiro Kamado.

Wind Breathing imitates roaring gales and whirlwinds, generating spinning slashes and sickle-shaped gusts that extend a swordsman's reach. One of the five core styles, it is wielded by Masachika Kumeno and Sanemi Shinazugawa.
