Tanjiro’s Breath of the Sun Power and Abilities Explained

Hinokami Kagura, also known as Sun Breathing, is the original and most powerful breathing technique in Demon Slayer, created by Yoriichi Tsugikuni. It consists of 13 forms that grant Tanjiro enhanced speed, power, and oxygen efficiency, plus the unique ability to prevent demon regeneration—making it the only technique proven capable of defeating Muzan Kibutsuji, the Demon King.

What Is Hinokami Kagura? Definition & Core Mechanics

Hinokami Kagura (火(ひ)の神(かみ)神楽(かぐら), "Dance of the Fire God") is a breathing technique that mimics the sun through the user's movements, techniques, and breath control. It grants the wielder supernatural speed, overwhelming power, and precision far beyond what standard swordsmanship allows.

The technique is unique because it operates on two levels: as a ceremonial ritual performed yearly by the Kamado family to honor the Fire God, and as a devastating combat form that transforms the dancer's movements into lethal attacks engulfed in solar flames.

What makes Hinokami Kagura fundamentally different from other breathing styles is its regeneration-blocking mechanism. Demon physiology relies on instantaneous cell regeneration to survive lethal wounds. The flames produced by Sun Breathing are incompatible with demon biology, preventing them from healing—a property that makes it the only technique with a proven chance against high-level demons and the Demon King himself.

The Origin Story  From Yoriichi to Tanjiro

Yoriichi Tsugikuni: The Creator & The Standard

Yoriichi Tsugikuni was the greatest Demon Slayer in recorded history—and, more significantly, the creator of all breathing techniques. Unlike other swordsmen who trained for years to master breathing forms, Yoriichi was born with them. He possessed two innate abilities: the Demon Slayer Mark (granting superhuman physical stats) and the Transparent World (allowing him to see a demon's internal organs and movements in real-time).

Yoriichi created Sun Breathing as the foundation technique, designed to replicate the sun's overwhelming and versatile power. Because Sun Breathing was so effective and adaptable, other swordsmen asked Yoriichi to modify it to suit their individual strengths and fighting styles. These modifications became the five fundamental breathing techniques: Water, Fire, Wind, Stone, and Thunder—each derived directly from Sun Breathing.

Most critically, Yoriichi nearly killed Muzan Kibutsuji in direct combat, scarring him and forcing Muzan into hiding. For over 1,000 years, Muzan has feared Sun Breathing and anyone who might wield it. The Hanafuda earrings Tanjiro wears throughout the series—a relic passed down through his family—are Yoriichi's earrings, which Muzan recognizes as a symbol of the Sun Breathing bloodline.

The Kamado Family's Hidden Legacy

After his encounter with Yoriichi, a swordsman named Sumiyoshi Kamado (Tanjiro's ancestor) befriended Yoriichi and learned Sun Breathing directly from him. However, Sumiyoshi was not a warrior by trade—he was an ordinary man. Rather than preserve Sun Breathing as a combat technique (which would have made it a target for demons and rival swordsmen), Sumiyoshi and his descendants transformed it into a ceremonial dance called Hinokami Kagura.

Every year on the New Year, the Kamado family would perform this ritual dance—ostensibly to honor the Fire God. In reality, they were preserving the footwork, breathing patterns, and movement sequences of Sun Breathing through cultural tradition. This disguise was brilliant: no one could suspect that a family's yearly ritual held the secret to the most powerful breathing technique ever created.

For centuries, the true combat applications of Hinokami Kagura were forgotten. It became just a dance, a cultural artifact. The Hanafuda earrings—Yoriichi's earrings, gifted to Sumiyoshi—were passed down as a family heirloom alongside the dance, their true significance lost to time.

Tanjiro's Awakening  From Water to Sun

Tanjiro grew up watching his father, Tanjuro Kamado, perform the Hinokami Kagura ritual every year. Tanjuro was secretly a keeper of the technique's legacy, though he was too weak and ill to use it in actual combat. Still, he ensured Tanjiro learned the dance, passing down the movements and the earrings—unaware that these would become Tanjiro's greatest asset.

When Tanjiro became a Demon Slayer, he trained under Sakonji Urokodaki, a former Hashira (elite-rank swordsman), in Water Breathing. Water Breathing is fluid, defensive, and effective—but it was never Tanjiro's true path. His body, his breathing, his instincts all belonged to Sun Breathing.

The breakthrough came during Tanjiro's battle against Rui, a Lower Moon demon. Desperate, cornered, and pushed to his limit, Tanjiro's muscle memory awakened. Without conscious thought, he performed the first form of Sun Breathing—Dance—a vertical slash engulfed in solar flames that shattered Rui's reinforced threads and changed everything. Tanjiro didn't know what he'd done. He'd stumbled onto power he didn't understand.

It wasn't until Shinjuro Rengoku, the former Flame Hashira, saw Tanjiro's Hanafuda earrings that the truth emerged: Tanjiro was a Sun Breather, a bearer of Yoriichi's legacy. From that moment forward, Tanjiro's mission became clear—master the Hinokami Kagura and unlock his destined power.

Hinokami Kagura vs Other Breathing Styles The Power Comparison

To understand why Hinokami Kagura is objectively the strongest breathing technique, it helps to see how it ranks against the five fundamental breathing styles derived from it.

Why Sun Breathing Dominates: It combines the speed of Thunder Breathing, the power of Stone Breathing, the versatility of Wind Breathing, and the fluidity of Water Breathing—without the weaknesses of any of them. More crucially, only Sun Breathing prevents demon regeneration, making it the only technique that can inflict permanent, lethal damage on high-tier demons.

Every other breathing style is a compromise. Sun Breathing is the complete package.

The 13 Forms of Sun Breathing  Complete Breakdown

Sun Breathing consists of 13 seamlessly connected forms, each flowing into the next. Yoriichi created the first 12 forms; the Thirteenth Form was discovered/developed later as a specific counter to Muzan's unique physiology.

Forms 1–4: Foundation & Offense

Form 1 Dance (舞(ま))

Tanjiro's first awakening. A single, powerful vertical slash engulfed in flames. Despite its simplicity, Dance unleashed with full Sun Breathing power can devastate even high-ranking demons. The form is the entry point—every Sun Breather learns Dance first.

Form 2  Clear Blue Sky (碧(あお)き空(そら))

Tanjiro performs a spinning, 360-degree rotation mid-air, unleashing flames in all directions. Perfect for countering wide-range attacks or handling multiple enemies simultaneously. The form's name refers to the unobstructed circular motion—like the sun blazing across a clear sky.

Form 3 Raging Sun (烈(れっ)日(じつ))

A dual-strike technique: two consecutive horizontal arcs that flow seamlessly into each other. Raging Sun maximizes consecutive damage output and is designed for breaking through an opponent's defenses by overwhelming them with relentless offense.

Form 4 Burning Bones, Summer Sun (灼(しゃく)骨(こつ)の夏(か)日(び))

A swift, upward-arcing slash capable of slicing through even the toughest demon flesh. The form emphasizes precision and power combined—useful for targeting specific weak points.

Forms 5–8: Intermediate & Maneuvering

Form 5  Setting Sun Transformation (落(ら)日(じつ)の沈(しず)潜(せん))

Tanjiro flips or inverts himself mid-air while slashing, making this technique ideal for simultaneous evasion and attack. By moving upside-down, he can dodge incoming strikes while delivering counterattacks from unexpected angles.

Form 6 Solar Heat Haze (日(ひ)の呼(こ)吸(きゅう) | 陽(よう)炎(えん))

A deceptive form where Tanjiro's strike appears to miss due to heat distortion and mirage effects, only to land a moment later. This technique is deeply psychological—opponents can't predict where the actual strike is coming. Invaluable against fast, high-intelligence demons.

Form 7 Beneficent Radiance (恵(めぐ)みの陽(よう)光(こう))

A spiraling, dance-like movement that emphasizes speed and elegance. The form allows Tanjiro to spin and cut through enemies with incredible momentum while maintaining perfect balance. The technique's name reflects its almost beautiful execution.

Form 8 Sunflower Thrust (向(む)日(ひ)葵(あおい)の花(か))

A fast, linear thrust designed for pinpoint accuracy. Unlike the broader, sweeping forms, Sunflower Thrust is a concentrated strike—ideal for exploiting weak points on an opponent's body (joints, neck, core).

Forms 9–12: Advanced & Sustained Offense

Form 9  Dragon Sun Halo Head Dance (龍(りゅう)日(ひ)の轍(わだち)頭(がしら)舞(ま)い)

Tanjiro unleashes a barrage of multiple flaming slashes in rapid succession, resembling a dragon's coiling movements. This form is particularly effective against large demons or those with fast regeneration—the continuous strikes prevent them from healing between hits. The form's name reflects its dragon-like flow and power.

Form 10 Fire Wheel (炎(ほの)の輪(わ))

A circular blade swing that allows Tanjiro to maintain momentum while counterattacking. By spinning his body, he creates a 360-degree defensive barrier while simultaneously striking outward. Excellent for offensive-defensive transitions when surrounded.

Form 11  Fake Rainbow (虹(にじ)の後(あと))

By twisting his body at high speed, Tanjiro creates a mirage-like effect that makes his actual position difficult to track. Opponents can't predict where he is—a critical evasion technique against speed-based demons. The form's name references the false visual information created.

Form 12  Flame Dance (炎(ほの)舞(ま))

A two-part combo consisting of a flaming vertical slash immediately followed by a horizontal strike. This form maximizes damage output by chaining consecutive high-power attacks without pause. By the endgame, Form 12 becomes Tanjiro's bread-and-butter technique for sustained offense.

Form 13  The Ultimate Technique

Form 13  Thirteenth Form (十(じゅう)三(さん)の型(かた))

The most powerful and most taxing technique in Sun Breathing's arsenal. The Thirteenth Form is not a single move—it's a continuous, cyclical execution of all 12 previous forms in rapid succession, creating an unbreakable chain of attacks.

This form exists for one purpose: to kill Muzan Kibutsuji.

Muzan's physiology is unlike any other demon's. His body contains multiple hearts and brains distributed throughout his torso. Standard attacks can destroy one vital organ, but Muzan regenerates the damage almost instantaneously. The Thirteenth Form was designed to exploit this specific weakness by executing all 12 forms—each targeting different body regions—in such rapid succession that Muzan cannot regenerate fast enough to survive.

The cost is catastrophic: using the Thirteenth Form for extended periods pushes the user's body to the absolute brink of death. Tanjiro uses it continuously for hours during the final battle against Muzan, suffering severe physical degradation with each passing minute.

Why Hinokami Kagura Is So Powerful The Mechanics Behind the Myth

Regeneration Prevention: The Game-Changer

This is Sun Breathing's defining advantage over all other breathing techniques.

Standard demon regeneration works like this: A demon suffers a wound. Their supernatural cells activate and rapidly knit the injury closed. Most breathing styles create physical damage—cuts, burns, blunt trauma—that demons simply heal away in seconds or minutes. This is why fighting demons is fundamentally asymmetrical: demons heal instantly; swordsmen get tired.

Sun Breathing's flames are different. The flames generated by Sun Breathing originates from the user's own life force and breathing, creating a unique energy incompatible with demon physiology. When these flames contact a demon's body, they prevent cellular regeneration. The wound doesn't just hurt—it won't heal.

This single property transforms the entire battle dynamic. With Sun Breathing, a Demon Slayer can actually inflict permanent, lethal damage on a demon. The wound stays open. The damage accumulates. Survival becomes possible.

Example: When Tanjiro uses Form 1 (Dance) against Rui's reinforced threads, the flames don't just cut the threads—they prevent Rui from repairing them instantly. This opening allows Tanjiro to press his advantage and defeat a demon he had no business fighting.

Speed, Power & Precision Enhanced

Beyond regeneration prevention, Hinokami Kagura grants the user three mechanical advantages:

1. Increased Oxygen Efficiency

Water Breathing and other derived techniques require specific breathing patterns tied to their individual forms. Sun Breathing's breathing cycle is more comprehensive and efficient, allowing the user to extract more oxygen from each breath. This translates to longer endurance, faster stamina recovery, and sustained offensive pressure.

Tanjiro notes that using Hinokami Kagura, he can fight for extended periods without the exhaustion that plagued him in Water Breathing.

2. Body Compatibility

Here's the crucial detail competitors miss: Tanjiro's physical body is genetically optimized for Sun Breathing.

Because his family preserved Sun Breathing for over 1,000 years, Tanjiro's physiology evolved to match the technique's demands. His muscle composition, lung capacity, bone density, and neural pathways are all aligned with Sun Breathing's requirements in ways they never could be with Water Breathing.

Initially, this incompatibility causes extreme strain—Tanjiro's body is fighting against a technique it was never trained to handle. But over time, as he repeatedly uses Hinokami Kagura, his body adapts and resonates with the technique, reducing strain and increasing output. By the final battle, his body has fully synchronized with Sun Breathing, allowing him to use it with far greater efficiency.

3. Versatility Without Pattern

The five fundamental breathing styles each have fixed patterns: Water flows in specific ways, Fire burns in predictable arcs, Wind cuts in recognizable patterns. This makes them learnable but limits their adaptability.

Sun Breathing has no set pattern. All 13 forms flow seamlessly into each other—any form can transition to any other form. This makes Sun Breathing infinitely adaptable to an opponent's movements and tactics. Tanjiro can chain forms unpredictably, keeping demons unable to predict his next move.

Power Scaling  Hinokami Kagura in Battle

Early Mastery: Rui Fight (Lower Moon 5)

Tanjiro's first use of Hinokami Kagura comes against Rui, a Lower Moon demon—the fifth strongest demon under Muzan's direct command.

At this point in the series, Tanjiro is competent with Water Breathing but clearly outmatched. Rui's reinforced threads can cut through Tanjiro's blade, and the demon's speed is overwhelming. Tanjiro is on the verge of death.

Then, without conscious effort, Form 1 (Dance) erupts.

The single vertical slash engulfed in solar flames shatters Rui's threads completely. More importantly, the flames prevent Rui from instantly regenerating and repairing the damage. For the first time, Tanjiro sees an opening—a window where the demon can actually be killed.

He barely survives this fight, but the message is clear: Hinokami Kagura fundamentally changes Tanjiro's power level. What was a losing battle becomes a narrow victory.

Takeaway: Form 1 alone is sufficient to decisively defeat a Lower Moon demon—something Water Breathing alone could never accomplish.

Intermediate Struggles: Gyutaro Fight (Upper Moon 6)

Fast forward to Gyutaro, an Upper Moon demon—the sixth strongest demon in Muzan's hierarchy. Upper Moons operate on an entirely different tier than Lower Moons. The power gap is immense.

During this fight, Tanjiro consciously uses Forms 1–10, gradually unlocking more advanced techniques. But here's the critical cost: each form taxes his body severely. His muscles burn, his organs strain, his vision blurs. The repeated use of Hinokami Kagura is literally destroying him from the inside.

Tanjiro attempts to combine Water Breathing with Hinokami Kagura—using Water Breathing's fluid, defensive movements to reduce the physical strain while maintaining Sun Breathing's offensive power. This hybrid approach works partially, but it's a band-aid solution. He's still dying.

The fight becomes a race against his own body's collapse. Tanjiro pushes past human limits, ignoring blood loss, organ damage, and nerve damage. He defeats Gyutaro not through superior technique but through sheer willpower and desperation.

Takeaway: Even with multiple forms mastered, Hinokami Kagura's physical cost nearly kills Tanjiro. Upper Moon demons represent a ceiling where technique alone isn't enough—the user must push beyond physical limits.

Peak Mastery: Muzan Final Battle

The final confrontation with Muzan Kibutsuji is the ultimate test of Hinokami Kagura.

At this point, Tanjiro has mastered Forms 1–12 and discovered the existence of Form 13—the technique Yoriichi created specifically to counter Muzan's physiology. Tanjiro learns the form from a memory fragment Muzan shares during their fight.

For hours, Tanjiro uses the Thirteenth Form continuously. He executes all 12 forms in rapid sequence, over and over, cycling endlessly. Each cycle targets different parts of Muzan's distributed vital organs. The relentless assault gives Muzan no opportunity to regenerate and heal.

But the cost is apocalyptic. Tanjiro's:

• Muscle tissue breaks down from the repeated strain

• Internal organs hemorrhage from the pressure

• Bones crack under the force

• Nervous system overloads

• Skin burns from the intense heat generated

By the end, Tanjiro is barely alive. He succeeds only because he literally gives everything—his body is destroyed in exchange for Muzan's destruction.

Takeaway: The Thirteenth Form is capable of killing even the Demon King, but the user pays with their body. Hinokami Kagura's ultimate power comes with an ultimate price.

Power-Scaling Summary Block:

"Hinokami Kagura is the only breathing technique proven capable of defeating Muzan Kibutsuji. Its combination of regeneration-blocking flames, enhanced speed/power/precision, and the Thirteenth Form's multi-vital-organ targeting makes it categorically more effective than all other breathing styles. Lower Moon demons fall to a single form. Upper Moon demons require multiple forms and push the user to critical limits. The Demon King requires the Thirteenth Form and the user's complete physical sacrifice."

The Cost  Physical & Spiritual Toll

Body Strain & Exhaustion

Hinokami Kagura's power comes with an extreme price: the technique is inherently damaging to the user's body.

This isn't just fatigue. This is cellular breakdown. Each use causes:

• Muscle micro-tears that accumulate with each form executed

• Joint inflammation from the intense rotational and impact movements

• Organ strain from the explosive breathing demands

• Nerve damage from channeling solar energy through the body

• Respiratory system overload from breathing at superhuman rates

Tanjiro experiences catastrophic exhaustion after even short bursts of Hinokami Kagura use. His first use against Rui leaves him barely conscious. The Gyutaro fight nearly kills him. By the Muzan battle, he's suffering from accumulated, cascading organ failure.

The Demon Slayer Mark Evolution & Compensation

As Tanjiro repeatedly pushes his body to the brink using Hinokami Kagura, something extraordinary happens: the Demon Slayer Mark awakens.

The mark manifests as a red, intricate pattern across Tanjiro's body—beginning on his forehead but eventually spreading across his chest and arms. This mark grants him:

• Superhuman physical stats (strength, speed, durability)

• Instinctive combat awareness (similar to Transparent World, but less developed)

• Enhanced healing and pain tolerance

• Increased lifespan potential (a hidden Demon Slayer Mark property)

The mark essentially allows Tanjiro's body to adapt and evolve beyond human limitations. It's his body's response to the extreme demands of Sun Breathing—a physiological evolution that lets him survive the technique's devastating costs.

This is the crucial distinction: other swordsmen cannot use Hinokami Kagura at high levels because they lack the Demon Slayer Mark. Tanjiro's mark awakens because his bloodline—his genetic connection to Yoriichi—makes him compatible with Sun Breathing. The mark is literally his body recognizing its true nature.

Timeline of Form Mastery

Understanding when Tanjiro learns each form shows his progression:

This timeline is crucial: Tanjiro doesn't awaken all 13 forms at once. He discovers them progressively, pushed by increasingly dangerous opponents. Each form unlocks only when his current power is insufficient—forcing him to dig deeper into his inherited legacy.

Connection to Greater Lore

Hanafuda Earrings & Muzan's Fear

The Hanafuda earrings Tanjiro wears are not mere fashion. They're a genetic marker—Yoriichi's earrings, passed down through the Kamado bloodline as a symbol of the Sun Breathing legacy.

Why does Muzan recognize these earrings and become obsessed with killing Tanjiro?

Muzan knows the truth: the Hanafuda earrings identify someone capable of using Sun Breathing. For over 1,000 years, Muzan has hunted down anyone who might resurrect Sun Breathing and pose a threat to his immortality. The earrings are his early warning system.

When Muzan first encounters Tanjiro's earrings, he doesn't just see a young swordsman—he sees the reincarnation of his greatest enemy, Yoriichi Tsugikuni.

Original Insight Block:

"The Hanafuda earrings aren't just a symbol—they're a genetic signifier that Tanjiro carries the Sun Breathing bloodline. Muzan's obsessive need to kill Tanjiro stems from his primal fear: that the one warrior who ever made him bleed has returned. The earrings are a threat to his 1,000-year dominion over the demon world. This transforms Tanjiro from an unlikely hero into a destined opponent—someone Muzan recognizes as fundamentally incompatible with his continued existence."

Demon Slayer Mark & Transparent World Connection

The Demon Slayer Mark and the Transparent World are two properties associated with Yoriichi Tsugikuni—gifts he was born with that made him the legendary swordsman he was.

• Demon Slayer Mark: Grants superhuman physical stats and instinctive combat awareness

• Transparent World: Allows the user to see a demon's internal organs, blood flow, and weak points in real-time

Yoriichi had both from birth. Most swordsmen can never awaken either.

Tanjiro awakens the Demon Slayer Mark through repeated use of Hinokami Kagura. His body, when pushed to extreme limits by Sun Breathing, evolves the mark as a survival mechanism. This is unprecedented—most Demon Slayers either have the mark or don't. Tanjiro earns it through will and legacy.

By the final arc, Tanjiro also glimpses the Transparent World—not fully, but enough to guide his attacks against Muzan's vital organs. This suggests that mastery of Hinokami Kagura can unlock what Yoriichi possessed innately.

The through-line is clear: Hinokami Kagura is the bridge connecting Tanjiro to Yoriichi's power. By mastering Sun Breathing, Tanjiro doesn't just gain technique—he awakens the dormant genetic potential that always existed in his bloodline.

Conclusion

Tanjiro's Breath of the Sun is far more than a powerful sword technique—it is the foundation behind Hinokami Kagura and the key to understanding his growth as a Demon Slayer. The 13 forms work together as a continuous sequence designed to maximize movement, stamina, precision, and damage against powerful demons. While Tanjiro initially struggles to use the technique without exhausting himself, his mastery of Total Concentration Breathing, Transparent World, and Selfless State allows him to push its potential much further.

The 13th Form ultimately represents the culmination of this fighting style, linking all twelve forms into a continuous cycle. Combined with Tanjiro's determination and adaptability, Breath of the Sun becomes one of the most formidable techniques in Demon Slayer. Its true strength isn't simply raw power—it's the ability to maintain relentless pressure while exploiting an enemy's weaknesses, making Hinokami Kagura a defining part of Tanjiro's journey.

FAQs

How many forms does Hinokami Kagura have?

13 forms in total. Yoriichi Tsugikuni created the first 12 forms as a unified, flowing technique. The Thirteenth Form was developed (or discovered) later as a specific counter to Muzan's unique physiology with its distributed vital organs. All 13 forms are designed to chain seamlessly together.

Is Hinokami Kagura stronger than other breathing styles?

Yes, objectively. Sun Breathing is the parent technique from which all other breathing styles are derived. The other five fundamental styles (Water, Fire, Wind, Stone, Thunder) are modifications created when Yoriichi adapted Sun Breathing to suit individual swordsmen's strengths. This makes Sun Breathing more versatile, more powerful, and more effective across all applications. Most critically, only Sun Breathing prevents demon regeneration, making it the only technique capable of permanently harming high-tier demons.

Can Tanjiro use other breathing styles after learning Sun Breathing?

Yes. In the manga's epilogue, Tanjiro demonstrates the ability to combine both techniques. He primarily uses Hinokami Kagura for offense, but can incorporate Water Breathing elements for fluid defense and endurance. This hybrid approach is rare—most swordsmen commit to a single breathing style—but Tanjiro's unique heritage allows him to draw from multiple traditions.

Does Tanjiro master all 13 forms?

He progressively masters Forms 1–12 throughout the series, with each form unlocking during increasingly dangerous battles. The Thirteenth Form comes late in the series when Senjuro sends Tanjiro a letter revealing its existence. Tanjiro learns the form's execution from a shared memory during his battle with Muzan. By the final battle, he has complete mastery of all 13 forms, though using the Thirteenth Form pushes him to the brink of death.

Why does Sun Breathing prevent demon regeneration?

The flames produced by Sun Breathing originate from the user's life force and breathing—creating a unique type of energy fundamentally incompatible with demon physiology. When these flames contact a demon's body, they inhibit the supernatural cellular regeneration that allows demons to heal wounds instantly. This isn't just a physical burn; it's a biological incompatibility that prevents the demon's healing factor from functioning. This is why even Lower Moon demons struggle against Sun Breathing and why Muzan himself feared it enough to hunt Yoriichi for centuries.

Is Tanjiro stronger than Yoriichi?

Not necessarily in raw power. Yoriichi was born with the Demon Slayer Mark and Transparent World, giving him innate advantages Tanjiro had to earn through training and bloodline awakening. However, Tanjiro's journey to master Sun Breathing is arguably more impressive than Yoriichi's innate power. Additionally, Tanjiro succeeds in defeating Muzan with the help of allies and friends—a victory Yoriichi couldn't achieve alone despite being a more naturally gifted warrior. In pure 1v1 power, they're comparable. In legacy and impact, they're equals walking different paths.

Can anyone other than Tanjiro use Hinokami Kagura?

Only members of the Kamado family bloodline can use Hinokami Kagura, as it's a family technique passed down through the generations. The bloodline appears to be genetically significant—the Hanafuda earrings and Tanjiro's body compatibility with Sun Breathing suggest the family was specifically bred (or evolved) to preserve this technique. Theoretically, other swordsmen could learn regular Sun Breathing techniques (as Yoriichi taught Sumiyoshi), but Hinokami Kagura is specifically tied to the Kamado lineage.
