Collection: Obanai Sword

Obanai's Coiled Precision: The Serpent Strikes 

Slithering in silence, coiling with resolve, and striking with unmatched speed—Obanai Iguro's Nichirin Sword is as unique and enigmatic as the Serpent Hashira himself. With its serpentine blade and ceremonial design, this weapon mirrors Obanai’s deadly precision and unwavering sense of justice.

Unlike traditional katanas, Obanai’s sword is serpent-shaped, curling and twisting like a fang in motion. This curvature grants him the ability to execute Serpent Breathing forms that confuse and outmaneuver demons with fluid, unpredictable patterns. His fighting style is a dance of deception, timing, and control. The sword doesn’t just cut—it constricts, ensnares, and punishes.

Obanai, cloaked in mystery and devotion, is a warrior of discipline and unshakable loyalty. His blade speaks to a life of burden, purpose, and ultimately, sacrifice. He speaks little, but his actions carve out justice with every coil of steel. The serpent blade is not simply a weapon—it's an oath wrapped in steel, a prayer of protection to those he vowed to serve.

His bond with Kaburamaru, the white serpent who never leaves his side, adds yet another layer of depth to his sword's symbolism. Together, they operate in silent synchronicity—the sword strikes, and Kaburamaru guides. Owning or admiring this weapon is not just a display of fandom, it is a homage to silent strength, and to love expressed through sacrifice.

Design Breakdown: Fangs of Fate

Obanai's blade design is one of the most visually striking in the Demon Slayer Corps. Its unique curvature isn’t ornamental; it serves both thematic and tactical purpose. Every coil of the blade represents calculated chaos—structured yet unpredictable.

Key Features:

• Blade Shape: Wavy, undulating curvature mimicking a snake in motion

• Blade Color: Silver with a light purple tint, reflecting Obanai's serpent motif

• Guard (Tsuba): Circular, shaped like an open snake's mouth with fangs

• Hilt Wrap: Deep green and white diamond pattern, matching his uniform

• Sheath: Matte black with serpent-scale engraving along the edge

The handle, wrapped with textured leather for extra grip, provides stability for erratic movement and spinning techniques. The slight weight imbalance from the blade's curvature is not a flaw—it's a feature that trained wielders use to shift momentum mid-strike.

Symbolically, the wavy blade represents life’s uncertain path—its dangers, beauty, and hidden strength. Its non-linear form is a metaphor for Obanai himself: guarded, misunderstood, but full of silent complexity and hidden passion.

Serpent Sword Variants and Collector Replicas

Collectors are drawn to Obanai's sword for its unique craftsmanship and storytelling potential. Whether you seek a showpiece or cosplay tool, there's a variant tailored to your style.

Deluxe Display Sets:

• Snake coiling stand with Obanai’s nameplate

• Kaburamaru figure curled along the blade

• Haori-pattern display cloth backdrop

• Sound module with subtle snake hiss effect

• Glass-etched quote from Obanai’s last words

Some collectors go further, building entire shrine-like setups that pair the sword with a bust of Obanai, background music from his emotional scenes, and carefully lit stages simulating moonlight. The replicas are so lifelike that the wavy steel glints like scales under light, and with motion-triggered audio, some displays even hiss when someone walks past.

Cosplaying Obanai Iguro: Fangs and Faith 

To become Obanai is to embrace duality—rigid order and chaotic grace. His sword plays a crucial role in conveying the serpentine rhythm of his breathing techniques and personal aura.

Cosplay Essentials:

• Vertical-striped black and white haori

• Dark Demon Slayer uniform

• White bandages covering lower face and neck

• Two-tone eyes (green and yellow) via contact lenses

• Kaburamaru companion (prop snake around shoulders)

• Serpent Nichirin Sword with curving blade

Enhancements:

• LED eyes or voice chip for Kaburamaru

• Slithering footwork choreography

• Fog-machine stage entrance

• Fabric overlay with snake-scale shimmer for dramatic effect

• Subtle hiss sound when unsheathing the sword

To perfect Obanai's presence, performers often adopt a slower, purposeful walk and a rigid stance. Pausing before speaking, tilting the head slightly as Kaburamaru "listens," and making eye contact only sparingly enhances the immersive effect. Your sword becomes your voice, and each movement speaks volumes.
