Discover this Zenitsu Demon Slayer LED mist katana - Yellow blade, 104 cm, designed for display and cosplay. This mist katana includes a 77-centimetre wood and acrylic blade with its scabbard, 104 centimetres in total, a light strip along the entire length, a cold mist diffuser, a charging port in the pommel, a white scabbard with yellow end caps, a pale flower guard and yellow lighting, and a single model with no options to choose from.

The scabbard is white, closed at both ends with bright yellow caps. The handguard is a pale flower with broad petals. The handle is white, wrapped with a cord that reveals yellow diamond shapes. The blade lights up in a vibrant yellow.

They were two under the same master

The old man who trained this character had another student, of the same age, who arrived at the same time. The two boys grew up together, learned the same style, and cordially despised each other throughout their training.

They were complementary and unequal: one never managed to master more than the first form of the style, while the other mastered them all except that one. The second was more gifted, more ambitious, and could not bear to see the first one remain. He eventually agreed to become a demon to never have to fear death again, and their old master, held responsible for this betrayal, took his own life. The two former comrades met face-to-face much later, and it was the boy with the unique form who prevailed, using a technique he had invented on his own that no one had ever shown him.

“One learned only a single form, the other all of them except that one. They met face-to-face.”

A vibrant yellow on white

This is the brightest model of the thirteen once lit: the yellow is almost white at the center of the blade, and the mist takes on the same hue, creating a wider halo than on the others. When turned off, the object remains very bright, with a white scabbard and pale handguard.

The set measures 104 centimeters, scabbard included, with a 27-centimeter handle. The blade is made of wood and acrylic, with no sharp edge or tip: it is an item for presentation and cosplay, not for cutting. Two effects work together and define the appeal of the model. A light strip runs the entire length of the blade and is activated by a button located under the handguard. At the same time, a cold white mist emerges at the base of the blade, just above the handguard, then travels along the blade and settles around it. It takes on the color of the lighting, making the blade appear as if it is smoking in its own color, as shown in the visuals. The pommel, at the end of the handle, features a USB-C port for charging. The scabbard closes over it and serves as a stand once the item is laid flat. The handle is wrapped in braided cord and the handguard is a custom piece, featuring the character's colors. A single form, and a technique invented on his own.

To get to know the character better, the full portrait of Zenitsu Agatsuma tells his story, from his constant fear to the First Form he performs in his sleep.

For his traveling companion, Tanjiro's blue-blade model. For a desk version, the 20 cm katana pen. And to display it, the openwork wooden stand.

⚔️ Boutique Demon Slayer: a shop devoted entirely to Kimetsu no Yaiba

At Boutique Demon Slayer, our aim goes beyond simply selling merchandise.

An independent French shop, we are devoted entirely to Demon Slayer: Kimetsu no Yaiba, built so fans can easily find the characters, symbols, outfits and signature objects of the anime and the manga.

From Tanjiro to Nezuko, by way of Zenitsu, Inosuke, Rengoku, Tomioka, Shinobu and the rest of the cast, we organise our catalogue to make finding products simpler, more coherent and more immersive.

A shop specialised in the world of Demon Slayer

Boutique Demon Slayer grew out of one simple intention: gathering the most complete selection of we could in a single place.

Our catalogue is built around several broad categories:

Demon Slayer clothing, to carry the series into everyday life through hoodies, t-shirts and other outfits;
Demon Slayer figures, for collectors and for anyone who wants their favourite characters on display;
Demon Slayer katanas, inspired by the weapons and the famous Nichirin blades of the series;
Demon Slayer accessories, a quieter way to keep Kimetsu no Yaiba close day to day;
Demon Slayer decorations, made to personalise a bedroom, a desk or a space given over to the series;
as well as Demon Slayer blankets and other items inspired by the show.

This makes it possible to browse the shop by type of product, but also by character and by the visual style each fan prefers.

Collections devoted to the best-known characters

The world of Demon Slayer rests largely on its characters, each with their own story, their own style and a visual identity fans recognise instantly.

That is why our shop also has collections devoted to the best-loved characters, among them Tanjiro Kamado, Nezuko Kamado, Zenitsu Agatsuma, Inosuke Hashibira, Kyojuro Rengoku, Giyu Tomioka and Shinobu Kocho.

The point is to let every fan reach the products tied to their favourite character quickly, without going through the whole catalogue.

A blog updated several times a week

Boutique Demon Slayer is not only an online shop.

We publish up to five articles a week on the world of Demon Slayer: Kimetsu no Yaiba, free to read whether you buy anything or not. Each page stands on its own and reads in one sitting.

We cover a wide range of subjects, including:

the characters of Demon Slayer and their stories;
the slayers and the Hashira;
the demons and their powers;
the Nichirin blades and what makes each one different;
the breathing techniques;
the fights that marked the series;
the anime and the manga;
the story arcs;
the symbols, outfits and signature objects;
as well as guides, rankings, explainers and analysis of the world of Kimetsu no Yaiba.

Our aim is content that helps newcomers understand the series better, and gives longtime fans details of this world to discover or rediscover.

These articles also create a natural link between the editorial content and , so a reader drawn to a character, a katana, an outfit or any precise detail of the series can carry on exploring in the shop.

A shop built for different kinds of fan

There is no single way to be a Demon Slayer fan.

Some are after a figure to complete a collection, others want to wear something inspired by their favourite character, display a Demon Slayer katana, decorate a room, or simply find a gift idea.

That is why we deliberately keep the catalogue varied, so it answers collectors, anime and manga fans, and people looking for a Demon Slayer gift for someone close.

Every category and every collection is designed to make that browsing as clear as possible.

A clear experience, centred on fans

We want discovering the shop to stay simple.

Products are organised by category, by character and by visual world, so visitors can move easily from a product to a related collection, then to a blog article or to other products that might suit them.

Our approach rests on four pillars: , immersive browsing, regular editorial content and an experience focused entirely on Demon Slayer.

We try to avoid the generic content that would pull the shop away from its subject.

Everything is built around one world: Demon Slayer: Kimetsu no Yaiba.

Our ambition

Our ambition is to make Boutique Demon Slayer France’s reference on a single world, that of Kimetsu no Yaiba, covered in depth.

A place that brings together:

a rich selection of ;
collections organised around the characters and the main product categories;
up to five articles a week on the series, free to read with nothing to buy;
browsing designed to make discovery easier;
free delivery within France, thirty days to change your mind, and an answer to every message;
and content that lets fans explore the world of Demon Slayer further.

Thank you for reading this far. If you have reached this page, the world of the slayers and the demons matters to you as much as it does to us. It is for readers like you that we spend so long on every product page and every article. Thank you for keeping this site alive, and enjoy your visit!
