The Sekido Potetto Mascot Plush from the Demon Slayer Swordsmith Village Arc represents one of those wonderfully niche pieces that Aniplex excels at producing for the Japanese domestic market. As one of the Upper Rank demons featured prominently in Tanjiro’s Swordsmith Village storyline, Sekido has earned a peculiar fan following despite his villainous role — and this chibi-style “Potetto” mascot reinterprets him with a softened, palm-sized charm that contrasts beautifully with his menacing on-screen presence.
Japanese plush merchandise tends to occupy a different design philosophy than Western tie-in toys. The stitching is denser, the embroidered face details are rendered with precision rather than printed shortcuts, and the proportions follow established mascot conventions like “nuigurumi” and “mochi-style” plushies. Aniplex’s Potetto line specifically leans into the “potato-shaped” silhouette, giving each character a stout, huggable form that has become highly collectible among Demon Slayer fans worldwide.

About This Item
This is the Sekido Potetto Mascot Plush Doll, produced by Aniplex as part of the Demon Slayer: Kimetsu no Yaiba Swordsmith Village Arc merchandise wave released in 2023 to coincide with the anime adaptation broadcast on Fuji TV. The “Potetto” (ポテっと, meaning “plump” or “chunky”) line is Aniplex’s signature stylized mascot format, where characters are rendered in a rounded, potato-like silhouette roughly 10–12 cm tall, with embroidered facial features and a strap loop for attachment to bags or display stands.
Sekido is one of the four manifestations of Hantengu, an Upper Rank Four demon, and his furious red-haired design translates surprisingly well into the cute Potetto aesthetic. The plush retains his signature scowling eyebrows, distinct hair tufts, and the dark color palette associated with his “anger” emotion. We have handled several pieces from this Potetto wave, and the build quality is consistent with Aniplex’s typical premium standards — clean stitching, no exposed seams, and color-matched threads throughout.

The Demon Slayer Franchise: Why Collectors Care
Demon Slayer: Kimetsu no Yaiba began as a manga serialized in Weekly Shonen Jump from February 2016 to May 2020, written and illustrated by Koyoharu Gotouge. The franchise exploded into mainstream consciousness after Ufotable’s anime adaptation premiered in April 2019, and the 2020 theatrical film Mugen Train became the highest-grossing Japanese film of all time, surpassing Spirited Away. According to Shueisha’s official sales figures, the manga has over 150 million copies in circulation worldwide.
The Swordsmith Village Arc, which aired in 2023, introduced the Mist Hashira Muichiro Tokito and the Love Hashira Mitsuri Kanroji, while pitting Tanjiro against the multi-bodied Hantengu — of which Sekido is the lead manifestation. This arc generated a massive merchandise push from Aniplex, the franchise’s primary licensing arm, including acrylic stands, ichiban kuji prizes, and the Potetto plush line.
Rarity and Value Factors
According to Aniplex+ store listings archived during the 2023 release window (https://www.aniplexplus.com/), the Swordsmith Village Potetto plushes were initially sold as a complete set as well as individual pickups, with arc-specific characters like Sekido, Karaku, Aizetsu, and Urogi seeing smaller production runs than perennial favorites like Tanjiro or Nezuko. Antagonist plushes typically have shorter shelf lives at retail because mainstream buyers gravitate toward protagonists — which paradoxically makes villain plushes harder to find on the secondary market two years post-release.
Condition rarity also plays a role: plushes with the original hangtag intact (Aniplex uses a distinctive square tag with holographic foil) command 20–40% premiums over tagless examples, as reported by Japanese hobby resellers like Mandarake and Suruga-ya.

Collector’s Guide: What to Look For
When evaluating a pre-owned Potetto plush, the most common issues are tag damage, fabric pilling on the body (especially on the rounded base where the plush sits), and yellowing or fading on lighter-colored fabric sections. We inspected this particular Sekido piece for all of these factors before listing — the embroidery threads on the face are intact with no loose stitches, and the body retains its original firmness without the sagging that can occur if the polyester filling has been compressed by prolonged display.
Pay particular attention to the strap or loop attachment point. On Potetto plushes, the loop is sewn into the top seam, and if a previous owner used the plush as an actual bag charm, friction wear can fray the loop or loosen the surrounding stitching. The dark fabric used for Sekido’s hair is also prone to lint pickup, so check for any embedded fibers under direct light. In my experience handling Aniplex plushes, sun exposure is the silent killer — even six months in indirect sunlight can desaturate the reds and blacks that define Sekido’s color identity.
Condition Checklist
- Hangtag: Check for the original Aniplex square tag with holographic foil; bent or torn tags significantly reduce resale value
- Embroidery: Inspect facial features for loose threads, snags, or asymmetry from manufacturing defects
- Fabric Condition: Look for pilling, lint accumulation, and color fading especially on darker panels
- Stuffing Integrity: Squeeze gently to confirm the filling hasn’t clumped or lost loft
- Packaging: Original polybag adds collector value but is rarely retained on opened items
Price Guide
Based on current Japanese secondary market data, Sekido Potetto plushes typically range as follows: loose pre-owned without tag in good condition sits around $25–35; pre-owned with original hangtag in excellent condition runs $40–55; sealed-in-bag examples with tag command $60–80 depending on demand cycles. Prices spike when the Swordsmith Village arc is rebroadcast or referenced in new Demon Slayer media. Antagonist plushes like Sekido tend to appreciate more steadily than protagonist plushes because they had smaller initial production runs but maintain dedicated collector interest. Always factor in international shipping and any applicable customs when comparing prices across regions.
Similar Items Worth Exploring
Collectors drawn to Sekido will likely want to complete the Hantengu manifestation set — Karaku (pleasure, pink), Aizetsu (sorrow, blue), and Urogi (joy, yellow) — all released in the same Potetto wave. Beyond the Hantengu quartet, the Swordsmith Village Arc Potetto lineup includes Muichiro Tokito and Mitsuri Kanroji, which pair naturally with the demon set for thematic displays. Earlier Potetto waves covered the Mugen Train and Entertainment District arcs, featuring Rengoku, Daki, and Gyutaro, allowing collectors to build chronological storyline displays.

Ichiban Kuji prize plushes from the same arc period also share design language but typically come in larger sizes around 18 cm.
Why Buy Japanese Collectibles from Japan?
Japanese collector culture places enormous emphasis on preservation — items are often kept in original packaging, stored away from sunlight, and handled with care that translates directly into better secondary-market condition. The Potetto line was sold primarily through Aniplex+ (the official online store) and select Japanese retailers like Animate, meaning units purchased domestically rarely passed through the rough handling of overseas distribution. Pre-owned pieces shipped from Japan also carry assurance against the counterfeits that have proliferated in Demon Slayer merchandise since 2020. According to the Japan External Trade Organization’s anti-counterfeiting reports, authentic Aniplex products carry consistent stitching density and tag printing that distinguishes them from knockoffs sold through unofficial channels.


Summary
The Sekido Potetto Mascot Plush is a charming, well-crafted piece that captures one of Demon Slayer’s most memorable antagonists in Aniplex’s signature chunky mascot format. Its 2023 release tied to the Swordsmith Village arc, combined with the typically smaller production runs for villain merchandise, makes it a genuinely collectible piece rather than a casual impulse buy. For collectors building a complete Hantengu set or a chronological Demon Slayer display, this is exactly the kind of pre-owned find worth securing while supply remains accessible.
