What is Demon Slayer: Infinity Castle?

Infinity Castle is the first film in a trilogy adapting the final arc of Koyoharu Gotouge's manga. It picks up where Season 3 left off, with the Hashira and Tanjiro pulled into Muzan's shifting fortress. Part 1 released worldwide in 2025. Part 2 has been pushed out of 2026 and is now expected in 2027, which actually helps collectors. It means the figure line stays active across the year instead of being stretched thin across back to back releases.

The best Demon Slayer Infinity Castle collectibles to buy in 2026

Here is what earns the money right now. Not everything on the shelf is a keeper. We have weighted this by build quality, how stable each piece looks on the aftermarket, and how well it displays next to figures you might already own.

1. S.H. Figuarts Tanjiro Kamado (Final Battle)

Bandai's six inch Figuarts line is the benchmark for posable anime figures, and this Tanjiro is built for the Akaza fight. The poseability is up there with the best Figuarts we have handled. Expect to pay in the region of £65 to £80 at UK retail. It is the definitive display piece for the climax of the film. Pair it with an Akaza figure and you have a diorama that tells the whole fight.

2. Figuarts Zero statues

Prefer static statues to posable figures? The Figuarts Zero line is where the drama lives. These suit a centrepiece shelf, with effect parts that catch a breathing technique mid swing. They sit higher up the price ladder, usually £80 plus, but they anchor a display in a way a standard figure cannot.

3. Funko Pop Infinity Castle wave

The Funko Pop wave is the low barrier way in. Tanjiro, Zenitsu, Inosuke and Giyu turn up as standard Pops, with rarer convention and metallic variants drawing a premium. Want a tougher pull near RRP? Pre-order early rather than chasing it after launch.

4. Banpresto prize figures

The budget hero. Banpresto prize figures land around £20 to £35 and fill out a shelf without emptying your wallet. The sculpt quality has come a long way, and for side characters they are often all you need.

5. Premium statues for the end game

Collect one definitive piece per character? The premium statue lines, the ten inch plus resin and high end PVC, are the ceiling. They run £250 and up, so most people buy one or two of their favourite character and stop there.

Buyer tips: how to buy Demon Slayer figures without getting burned

Three rules we would give anyone starting or expanding a Demon Slayer shelf in 2026.

Buy authentic. The bootleg market for Figuarts has got scary good. Check the QR code on the box for S.H. Figuarts pieces, and the back of box barcode against Bandai's registry. Box feel matters too. Real Bandai boxes use a thicker card stock than most fakes.

Pre-order when you can. Figuarts and Figuarts Zero lines routinely sell out on day one and climb on the aftermarket within months. Pre-ordering at RRP is almost always the smart play.

Plan your shelf. Obvious, but Demon Slayer has a roster north of twenty characters. Work out who you actually want before buying whatever pops up. Fourteen Tanjiro variants and no Zenitsu looks odd on a shelf.

Common mistakes UK collectors make

• Paying import fees without checking. Import direct from Japan and you can get hit with customs plus a Royal Mail handling charge. Buying from a UK stockist often works out cheaper once the fees are added up.
• Chasing every variant. Convention exclusives, metallics and glow in the dark versions add up fast. Pick a lane and stick to it.
• Displaying in direct sunlight. PVC yellows. Figuarts in particular fades after a year or so near a south facing window. Use UV filtered cabinets or rotate the figures.
• Binning the box. Keep it. Resale value drops without it, and for Figuarts the box can be a fifth of the resale price.

Where Infinity Castle figures are heading

With Part 2 now expected in 2027, expect a steady drip of figures through the rest of 2026 rather than one big wave. The smart money buys core cast figures now at RRP. When the next film's hype hits, secondary prices on the 2026 Final Battle figures tend to climb. That pattern shows up again and again with Bandai anime lines. We saw it with the Mugen Train wave, and again with the Swordsmith Village figures.

FAQ

Q: When does Demon Slayer Infinity Castle Part 2 release?

Part 2 is not part of the 2026 line up and is now expected in 2027. No firm global date has been confirmed. Going on how Part 1 rolled out, a Japan release would likely be followed by international screenings a few months later.

Q: Are the S.H. Figuarts Demon Slayer figures worth the price?

Yes, if you want posability and display quality. Figuarts are the premium standard for six inch anime figures. They hold value well and pair with every other Figuarts line. If you just want something on a shelf, Funko Pops or Banpresto prize figures do the job.

Q: Where can UK collectors buy authentic Demon Slayer figures?

Stick to UK stockists who import directly from Bandai or licensed distributors, with a clear returns policy and an authenticity guarantee. Be wary of unknown marketplace sellers for Figuarts pieces, as bootlegs have become common.

Q: How much should I pay for a Demon Slayer Funko Pop in the UK?

Standard Pops sit around £11 to £15 at RRP. Chase and metallic variants run £20 to £40. Convention exclusives can climb past £60 on the aftermarket if they sell out.

Q: What's the best starter figure for a new Demon Slayer collector?

The Funko Pop Tanjiro. Under £15, instantly recognisable, fits anywhere. From there, a Banpresto prize figure, then your first S.H. Figuarts piece. That is the upgrade path we see most UK collectors take.

Q: Is Demon Slayer Infinity Castle available to watch at home?

Home availability shifts by region and over time, so check the current UK digital and streaming listings. A home release usually follows several months after the cinema run.
