Zenitsu Katana (Demon Slayer) – ゼンイツ

Embrace Thunder Breathing with the official Zenitsu Katana replica

This Zenitsu Katana is a faithful replica of the Nichirin sword wielded by Zenitsu Agatsuma, one of the core characters from Demon Slayer: Kimetsu no Yaiba. Beautifully designed in a pure white finish with golden lightning streaks, this blade reflects Zenitsu’s personality, timid and nervous on the surface, but with devastating strength hidden beneath.

Zenitsu’s katana is no ordinary weapon. In the Demon Slayer lore, each Nichirin sword adapts to the user’s breathing style, forging a spiritual and visual connection between soul and steel. Zenitsu’s blade manifests in dazzling golden lightning, representing his Thunder Breathing (Ikazuchi no Kokyū) technique, which allows him to move at blinding speed and strike in a single decisive blow.

Crafted from high-carbon 1045 steel, this unsharpened replica maintains the aesthetics and proportions of the original anime design. It’s lightweight and balanced (~1.1 kg), making it perfect for cosplay, martial arts practice (kata), or display.

A blade forged in fear, perfected in flash

Zenitsu Agatsuma might be the most unlikely demon slayer in the Corps, cowardly, anxious, and prone to breakdowns. But when pushed beyond his limit, especially in sleep or unconscious states, he unlocks the full potential of his Thunder Breathing, demonstrating unmatched precision and power.

This replica features a gold-trimmed white tsuba, round with triangle cutouts, the same design seen throughout the series. The tsuka (handle) is wrapped in pure white ito over golden diamond accents, a clean and noble contrast that reflects Zenitsu’s innocence and hidden resolve.

The saya (scabbard) is completely white, lacquered to a mirror shine and capped in golden fittings. This design choice makes the Zenitsu Katana one of the most visually striking Nichirin blades in the entire Demon Slayer universe. The golden thunder motif engraved on the blade symbolizes speed, danger, and divine punishment, perfect for a swordsman whose moves mimic the wrath of the skies.

This is more than a replica, it’s a collectible representation of Zenitsu’s growth, his fear overcome through courage, and his unmatched ability to strike down evil in a single motion.
