A Final Symphony of Swords: Every Breathing Style Set to Collide in the Infinity Castle Arc

The finale of Demon Slayer: Kimetsu no Yaiba is hurtling towards its climactic conclusion, and the upcoming Infinity Castle Arc promises to be the most brutal and visually spectacular chapter in the series’ history. As the Demon Slayers are plunged into the shifting, disorienting labyrinth of Muzan’s fortress, they will unleash the full spectrum of their swordsmanship and breathing techniques in a last-ditch effort to end the war. This final arc is not just about raw power; it’s a showcase of every major breathing style, from the foundational forms to the unique, self-taught techniques that have defined the series’ most memorable characters. This article will serve as a comprehensive guide to every confirmed breathing style that will be on display as the Demon Slayer Corps makes its final stand.

The Foundations of the Final Battle: The Core Breathing Styles

The Infinity Castle Arc will feature a grand reunion of the Hashira, the elite swordsmen who have mastered their respective breathing styles to the absolute limit. These are the core techniques that form the backbone of the Demon Slayer Corps, and their full power will be unleashed against the Upper Moons and Muzan himself.

• Water Breathing: Used by the stoic Water Hashira, Giyu Tomioka, and the series’ protagonist, Tanjiro Kamado, this style is characterized by its fluidity and adaptability. Giyu’s mastery of the eleventh form, “Dead Calm,” will be crucial for his fight against the formidable Akaza, while Tanjiro will use his foundational Water Breathing skills to navigate the chaos of the Infinity Castle.
• Flame Breathing: Though the Flame Hashira, Kyojuro Rengoku, is no longer with them, his legacy lives on through his father, Shinjuro, and the spirit that burns within Tanjiro. The power and raw force of this breathing style are a testament to its users’ unwavering spirit.
• Stone Breathing: The most powerful of the Hashira, Gyomei Himejima, wields this style. Characterized by its immense power and defensive capabilities, it uses a flail and axe instead of a standard Nichirin Blade. Gyomei’s battle against the Upper Moons will be a masterclass in this technique.
• Wind Breathing: The aggressive and short-tempered Sanemi Shinazugawa, the Wind Hashira, uses this style, known for its sharp, relentless attacks that mimic gusts of wind. His brutal fighting style will be on full display in his confrontation with the Upper Moon One, Kokushibo.
• Thunder Breathing: Zenitsu Agatsuma’s mastery of the first form of this style, “Thunderclap and Flash,” will be crucial in the Infinity Castle. He will face his former dojo brother, Kaigaku, who also uses a corrupted version of Thunder Breathing.

The Specialized and Unique Techniques

Beyond the core styles, the Infinity Castle Arc will also highlight the unique breathing techniques created by the Hashira to match their individual strengths and personalities. These techniques, often offshoots of the core styles, are some of the most visually stunning and effective in the series.

• Mist Breathing: The young prodigy Muichiro Tokito, the Mist Hashira, uses this style, which is an offshoot of Wind Breathing. Its elusive and disorienting forms, shrouded in mist, make it incredibly difficult for opponents to track his movements.
• Serpent Breathing: Obanai Iguro’s unique style mimics the serpentine movements of a snake, allowing him to attack from unconventional angles. This style will be central to his fight against the demons of the Infinity Castle.
• Love Breathing: Mitsuri Kanroji’s unique swordsmanship is defined by its flexible, whip-like movements, which are an offshoot of Flame Breathing. Her “Love” style, combined with her immense flexibility, makes her a unique and powerful combatant.
• Flower Breathing: Kanao Tsuyuri’s style, passed down from her late sister Kanae, is a graceful and powerful offshoot of Water Breathing. The final form, “Equinoctial Vermilion Eye,” which enhances her vision at a great cost, will be a key factor in her battle against the Upper Moon Two, Doma.
• Insect Breathing: Shinobu Kocho, the Insect Hashira, developed this style to compensate for her lack of physical strength. Instead of a powerful slash, her style uses a specialized blade and deadly poisons to kill demons, a technique that will be used to its full potential in the Infinity Castle.

The Ultimate Power: Sun and Moon Breathing

The most anticipated aspects of the Infinity Castle Arc are the legendary, original breathing styles: Sun and Moon Breathing. These are the techniques that started it all, and they will play a crucial role in the final showdown.

• Sun Breathing (Hinokami Kagura): Tanjiro’s family tradition, the Hinokami Kagura, is revealed to be the very first breathing style, Sun Breathing, created by the legendary Yoriichi Tsugikuni. As Tanjiro pushes his body to its absolute limits, he will finally unlock the true, full power of all thirteen forms of this ultimate breathing style, which is the only technique capable of permanently damaging Muzan’s cells.
• Moon Breathing: This style is wielded by the Upper Moon One, Kokushibo, a former Demon Slayer and Yoriichi’s brother. His style, a corrupted and demonic version of Sun Breathing, creates razor-sharp, crescent-moon-shaped slashes that are constantly shifting and changing. The brutal fight against Kokushibo will not only be a test of skill but also a tragic clash of ideologies and a final look at the true power of the first breathing styles.

The Infinity Castle Arc is set to be a grand culmination of every technique, every sacrifice, and every moment of training from the entire series. It is a final symphony of swords, where every breathing style will be pushed to its absolute limit, all in a desperate attempt to bring an end to the era of demons.
