Rengoku Katana (Demon Slayer) - レンゴク

Unleash fiery justice with this Rengoku Katana from Demon Slayer

This Rengoku Katana replica is a striking tribute to the Flame Hashira, Kyojuro Rengoku, from the anime Demon Slayer: Kimetsu no Yaiba. Known for his explosive flame-based techniques and unwavering sense of justice, Rengoku left an unforgettable impression in the Mugen Train arc. This sword captures his heroic energy with vibrant detailing, precise proportions, and anime-accurate styling, making it a must-have for fans, cosplayers, and collectors.

The blade is forged from 1060 high-carbon steel, offering resilience and visual sharpness. Finished in black with vivid red flame patterns licking up from the habaki (blade collar), this sword mirrors Rengoku’s Nichirin blade exactly as seen in the anime. The iconic kanji characters inscribed on the blade, "Destroy Demons" (悪鬼滅殺, Akki Messatsu), represent the Demon Slayer Corps' mission and embody Rengoku's fiery resolve.

With an overall length of approximately 103 cm and a weight of ~1.2 kg, this katana feels authentic in the hand. Though it is unsharpened for safety, its proportions and structure allow for martial arts kata, precise display, or performance cosplay.

A legendary Nichirin blade forged for fans of Kyojuro Rengoku

The tsuba (guard) is a signature six-pointed flame design in vivid orange with black edging, a faithful recreation of Rengoku’s sword in the anime. This unique guard sets the katana apart from traditional samurai blades and reflects the heat and explosive nature of flame breathing techniques. The tsuka (handle) is wrapped in white ito over faux ray skin, delivering an elegant contrast and comfortable grip. Orange accents on the handle fittings echo Rengoku’s color palette and further tie this piece to his character design.

The saya (scabbard) is finished in bright white lacquer, decorated with angular black flame motifs that mirror the sword’s burning spirit. The matching white sageo (cord) is tied in a traditional manner, giving the sword an authentic feel. Whether displayed on a rack or worn across the back for cosplay, the saya reinforces the blade’s iconic identity.

Every aspect of this katana speaks to Kyojuro Rengoku’s philosophy, his relentless optimism, courage in the face of despair, and belief in the next generation. This replica sword isn't just a piece of anime merchandise. It’s a tribute to a warrior who stood tall when others fell and lit the path for Tanjiro and his companions.
