Kyojuro Rengoku Niformation Deformed Sticker from Demon Slayer — Bandai Series 3-05 Guide
What This Item Is
This sticker is part of Bandai’s Niformation line, a collectible series featuring anime characters rendered in a chibi (deformed) style. The name “Niformation” appears to be a portmanteau blending the Japanese concept of resemblance with “information” or “deformed,” reflecting the series’ focus on compact, character-faithful miniature art. Item number 3-05 identifies this as the fifth entry in the third wave of the series. The sticker depicts Kyojuro Rengoku in a dynamic running pose, sword in hand, against a gold and reddish-brown background that echoes his flame motif. A vertical kanji character reading “Ko” (brilliance/radiance) appears on the right side of the piece, strongly suggesting this is a special holographic or sparkling variant — a finish known in Japan’s sticker and card collecting culture as a “kira” spec. The sticker is housed in a clear vinyl sleeve, which is standard practice for collectible preservation in the Japanese market.
The Franchise and the Character Behind the Design
Demon Slayer: Kimetsu no Yaiba began as a manga by Koyoharu Gotouge, serialized in Weekly Shonen Jump from 2016 to 2020. The anime adaptation produced by ufotable aired in 2019, and the 2020 theatrical film Mugen Train (Infinity Train) became the highest-grossing film in Japanese box office history at the time, earning approximately 40.4 billion yen. That film placed Kyojuro Rengoku at its center. As the Flame Hashira — one of the elite swordsmen of the Demon Slayer Corps who wields Flame Breathing techniques — Rengoku became one of the franchise’s most recognized characters internationally. His visual identity is immediately distinctive: hair with a red-to-yellow gradient, a flame-patterned haori, and a black-hilted blade with red accents. Even in chibi form, those design elements translate clearly, making this sticker recognizable at a glance to any fan of the series.
Japan’s Collectible Sticker Tradition and What Makes This Format Significant
Collectible stickers occupy a deeply rooted place in Japanese popular culture, with roots tracing back to the Bikkuri Man sticker phenomenon that began in 1977. Characters were assigned to individual sticker cards, distributed in sets, and traded among collectors — a culture that carries forward directly into modern lines like Niformation. Food toys (shokugan), a broader Japanese category of small collectibles originally bundled with candy, evolved to include standalone sticker and card releases as the hobby matured. Within this tradition, kira or holographic variants — like this “Ko” edition is thought to be — function as the rarer entries within a given set, distinguished from standard prints by their reflective finish. For collectors building a complete run of a series, identifying the exact variant matters, which is why the series number 3-05 carries practical weight beyond simple labeling. Bandai, as one of Japan’s largest toy and hobby manufacturers and an official Demon Slayer licensee, produced this item for the domestic Japanese market, meaning it was not distributed through standard retail channels outside Japan.
