Building a Demon Slayer gaming setup

A Demon Slayer setup is built from the desk. The desk mat covers the largest surface and sets the palette for the rest.

The range has some sixty pieces. They are spread between the desk, the keyboard, the console and the phone.

This guide gives you the real dimensions, the compatibility and the prices, and what you need to check before ordering.

The five pieces of a setup

The budget depends mainly on the desk mat. A 60 x 30 cm format costs €39.90, a 120 x 60 cm in 3 mm goes up to €139.90.

The rest stays affordable. Phone and earbuds cases start at €14.90, which makes them the first pieces of a Demon Slayer setup.

The keycap is the most targeted purchase, at €39.90 for a single key, which requires a mechanical keyboard.

You can browse the range from the desk mats section, and the guides and tips page brings together the other ranges.

The five pieces are not bought together. Take the desk mat first and add the rest over the months: that way you spread the budget.

The desk mat

It is the centrepiece of the setup. Six sizes, from 60 x 30 cm to 120 x 60 cm, and from 2 to 4 mm thick, that is, fourteen combinations in the same selector.

Choose the format according to your desk’s depth. An 80 x 40 cm takes a full-size keyboard and a mouse, a 120 x 60 cm covers the entire worktop.

The Rengoku desk mat in the flames lays out its image across the full width, with a stream of fire running through the black background.

Thickness changes comfort. Two millimetres are enough on a smooth desk, three or four cushion the wrists more.

The price follows surface area and thickness, from €39.90 in 60 x 30 cm to €139.90 for the large format in 3 mm.

The designs are conceived as panoramas. An off-centre character, a background spreading across the full width, because a desk mat is always seen from above and from the side.

Sixteen designs cover the family, the Hashira leading the way, and the keycaps are found in the keyboard and desk section of the catalogue.

The image covers the whole surface. Printed edge to edge, it stays readable under the keyboard as well as around the mouse.

The large format has a practical advantage. It protects the desk from keyboard scratches and mug marks, as well as carrying the Demon Slayer image.

Check the edges when you unpack it. That is where a desk mat gives way first: look at it on day one rather than after six months.

The price gap comes down entirely to the format: €39.90 for the 60 x 30 cm in 2 mm, €139.90 for the largest format in 3 mm, on the same listing and with the same design.

The blaze on this mat is that of Kyojuro Rengoku, the Flame Hashira, who defends five carriages of the Mugen Train.

Keycaps

The heart of the family comes down to one shape: the moulded resin keycap in the form of a chibi head, at €39.90 each.

Fitting one requires a mechanical keyboard. The Giyu Tomioka chibi resin keycap fits on a cross-stem switch, the market standard.

A membrane keyboard will not do. Its keys are attached to a sheet, and none can be removed to be replaced.

The relief stands higher than an ordinary key. A moulded resin head rises higher than a flat cap, which you feel when typing on the middle rows.

The most common use is decorative. Put it on a little-used function, Esc or Caps Lock, rather than in the middle of the typing area.

Twelve characters are available in chibi form, the nine Hashira, Tanjiro, Zenitsu and Inosuke, each with their own expression.

The price per unit is surprising: €39.90 for one key is the price of an entire entry-level keyboard, which makes it a collector’s item.

Resin scratches less than a plastic cap. It withstands the rub of a finger without the paint coming off, provided you do not hit it every day.

The demons have their big-head keycaps, Akaza, Doma and Kokushibo at €69.90, and four full PBT sets, in Tanjiro, Nezuko, Zenitsu or Inosuke’s colours, replace a whole keyboard of 61 to 108 keys for €64.90.

The twelve chibis cover the nine swordsmen presented on our page about the Hashira of the Demon Slayer Corps, Giyu Tomioka included.

Console cases

Two generations are covered. The first Switch at €29.90, and the Switch 2 at €54.90, with different constructions.

The soft first-generation Switch case includes a back cover and two controller covers, in six designs matched to their colour.

The Switch 2 moves to a hard case. The Rengoku hard case for Switch 2 comes in three pieces, console and two matching controllers.

The cut-outs are designed for the controls. Buttons, ports and ventilation remain accessible: check this point on any console case.

The generation matters absolutely. A Switch 2 case does not fit a first-generation Switch, and vice versa.

Eighteen products make up the console cases section, split between the two generations.

Soft and hard cases do not protect in the same way. Soft cushions a fall, hard prevents scratches but passes on more of the impact.

The added weight matters on a handheld console. A three-piece hard case thickens the grip, which some players like and others not at all.

Six designs cover the first generation. Zenitsu in yellow, the trio and Nezuko in blue, Nezuko in pink, Shinobu in white, Shinobu and Kanao in grey, and a group scene, each matched to its colour.

The console also has its games, listed on our page about the Demon Slayer video games.

Phone cases

The family covers a considerable number of models. Hundreds of phone models are offered in the selectors, for €14.90 to €29.90 each.

The big brands are catered for. The iPhone, Samsung Galaxy, Xiaomi Redmi, Honor and Huawei ranges each have their cases.

The finishes vary from one product to another. A frosted back with a metal edge, transparent with a coloured glow, matte, or a coloured edge depending on the model chosen.

The double selector needs your attention. One menu for the character, another for the phone model, and you need to set both before confirming.

The exact model matters. An iPhone 16 Pro and an iPhone 16 Pro Max have neither the same size nor the same camera block, and a case will not fit from one to the other.

The cases section of the catalogue brings together the twelve ranges, phones and earbuds alike.

The raised edge protects the screen. It prevents direct contact when the phone is laid face down on a table, a detail the listings specify on some of the models.

The big ranges cover several years of devices. The selectors go from the iPhone 17 Pro Max to much older models, which makes the range usable even if your phone is a few years old.

The selectors are wider than they look. A single listing in the Demon Slayer accessories range offers nine characters and twenty-seven phone models, that is, two hundred and forty-three combinations on the same product.

Earbuds cases

Two lines complete the range: €17.90 for Galaxy Buds, €22.90 for AirPods.

The black silicone AirPods case with a carabiner offers eleven chibi designs and covers five generations.

The carabiner changes the use. It lets you hook the case onto a bag or a belt loop rather than leaving it at the bottom of a pocket.

Galaxy Buds have their own range. Six faces in silicone, eight generations covered, at €17.90 per case.

Silicone protects against light falls. It cushions the impact of a fall from a pocket, without promising more on a hard floor.

It is the cheapest entry point in the Demon Slayer accessories range.

Chibi designs dominate this family. The small format of an earbuds case does not suit a detailed portrait, and the rounded drawing reads better there.

The case stays functional under the cover. Wireless charging works through the silicone on most models: check the listing if that is your main use.

The two ranges do not cover the same number of devices. Eight generations of Galaxy Buds at €17.90, five generations of AirPods at €22.90, with eleven designs on one side and six on the other.

The chibi designs often feature the trio of Tanjiro, Zenitsu and Inosuke, along with Nezuko.

How to build a coherent setup?

The rule comes down to one dominant colour. The desk mat sets the palette, and the rest is chosen in the same family of shades.

A single character is often enough. A desk mat, keycap and console case with the same name give a readable desk, which works less well with four different faces.

The Hashira’s palettes lend themselves well to the exercise. Orange for Rengoku, blue for Tomioka, purple for Shinobu, turquoise for Muichiro.

Black backgrounds dominate the range. Most desk mats start from a dark background, which leaves room for a light keyboard or a white mouse.

Lighting extends the work. A night light or a backlit frame behind the screen completes the look without cluttering the worktop.

The lamps and night lights section brings these pieces together, detailed in our guide to decorating a Demon Slayer bedroom.

Mixing ranges shows quickly. A Demon Slayer desk mat under a colourful keyboard and a mouse with changing lighting produces a cluttered desk rather than a coherent whole.

The keycap weighs heavily in the budget: €39.90 for a single key, while a phone case and an AirPods case from the Demon Slayer range cost €37.80 together.

The wall behind the desk

The setup does not stop at the worktop. The wall behind the screen is treated with the same characters.

Posters come in up to ten formats. From 13 x 18 cm to 55 x 90 cm, unframed, from €14.90 to €54.90 depending on size.

Diamond painting offers another route. The Tanjiro Water Breathing diamond painting kit comes with an adhesive canvas, rhinestones, a pen, wax and tweezers.

The format goes from 20 x 30 to 50 x 70 cm. The price follows, from €29.90 to €69.90, and the work takes evenings rather than minutes.

Figures complete the shelf. A ten to fifteen centimetre format fits between a screen and a lamp without cluttering.

The shop’s posters and the diamond painting section cover this part of the setup.

The webcam changes everything if you stream. Its field captures the wall behind your shoulder, and it is often the only part of the setup the audience sees.

Care

Wash the desk mat by hand. Lukewarm water, mild soap, a soft brush on the printed surface, and dry flat for a whole day.

Avoid the machine for large formats. The drum folds the desk mat, which then warps.

Resin keycaps come off with a puller. A small looped tool, often supplied with a mechanical keyboard, avoids forcing the stem.

Console cases come apart for cleaning. A dry cloth on the console, a damp cloth on the case, never any product in between.

Phone cases yellow over time. Transparent models are the most exposed, especially near a window.

The silicone of earbuds cases holds dust. A rinse in clean water is enough, with the case removed first.

Clean the desk mat more often than you think. Crumbs, dust and hand marks build up on a fabric surface, and a monthly clean is enough to keep it tidy.

What mistakes should you avoid?

The first is ordering a desk mat without measuring the desk. Six sizes exist, and a 120 x 60 cm overhangs most worktops.

The second is buying a keycap for a membrane keyboard. It will not fit, and the €39.90 price makes it a costly mistake.

The third is mixing up console generations. A Switch 2 case does not fit a first-generation Switch.

The fourth is setting only one of the two selectors on a phone case. The character and the model are chosen separately.

The fifth is overlooking the desk mat’s thickness. Three or four millimetres change wrist height and comfort over long sessions.

The sixth is mixing four characters on the same desk. The result loses the coherence a single name would have given.

The seventh is forgetting the puller tool for a keycap. Removing a cap by hand twists the cross stem and damages the switch underneath.

What budget for a Demon Slayer setup?

Under €25, the cases: €14.90 for the phone case, €17.90 for the Galaxy Buds case, €22.90 for the AirPods case.

Between €25 and €50, the desk takes shape: the 60 x 30 cm desk mat at €39.90, the first Switch case at €29.90, the chibi keycap at €39.90.

Between €50 and €100, the setup grows: the 80 x 40 cm desk mat at €64.90, the Switch 2 case at €54.90, the full keycap set at €64.90.

Above €100, the large format. A 120 x 60 cm desk mat in 3 mm at €139.90 covers an entire desk on its own.

The price brackets are listed separately. The selection under €20 and the selection between €40 and €70 cover most of the range.
