Demon Slayer LED Vapor Katana 1:1 Scale Prop Replica (Mist Effect, LED Glow)

Breathe mist. Command light. Slay demons in style. This 1:1 scale prop replica of a Demon Slayer Corps katana takes cosplay to the next level with vapor-emitting technology and LED glow built directly into the blade.
 

Watch as mist rolls down the edge, scattering the LED light into an ethereal, fog-shrouded aura — perfect for recreating Mist Breathing, Love Breathing, or Sun Breathing effects. Each katana comes with a matching plastic sheath and is available in multiple character-styled blade designs.
 

Choose from multiple character-themed blade designs based on their own weapons.

General Care Instructions: Store in cool, dry place. Avoid dropping or striking hard surfaces. Do not use alcohol or solvents when cleaning the blade. Use only distilled water for vapor.

Important Notes: This is a decorative prop replica — not a functional weapon. Blade is blunt. Vapor is non-toxic and cool to the touch. Safe for skin and breathable. Do not point directly at eyes.

Vapor effect works best in cool, low-humidity environments. High humidity may reduce visible mist density.
 

Convention staff may ask to see the vapor system — check local rules.
 

Key Features:
 

Vapor Emission System – The blade produces a fine, cool mist that flows along the surface and edge, creating a supernatural fog effect.
 

LED Illumination – Internal LEDs shine through the acrylic blade core, casting light through the vapor for a stunning glowing-fog effect. Multiple lighting modes (steady glow / pulsing / breathing effect) depending on model.
 

Vapor + Light Interaction – When vapor passes over the lit blade, the light scatters through the mist, creating a 3D volumetric glow that photos and videos cannot fully capture — it must be seen in person.
 

True 1:1 Scale – Total length 40 inches (approx. 101.6 cm). Blade length 77cm (approx. 30.3 inches) — accurate to anime proportions.
 

Signature Blade Curve – Blade angle exceeds 60 degrees, faithfully recreating the distinctive katana silhouette of the Demon Slayer Corps.
 

Nanzhu + Acrylic Blade – Core is Nanzhu (bamboo) for structural rigidity, overlaid with clear acrylic for LED light transmission and vapor channels.
 

Plastic Sheath Included – Each katana comes with a durable plastic scabbard (character-themed color matching) for storage, transport, and convention safety.
 

Multiple Character Styles – Choose the blade design that matches your favorite Hashira or Slayer:
