Demon Slayer’s Post-Infinity Castle Future Gets First Official Update, And It’s Bigger Than Fans Expected

Published Nov 12, 2026, 2:06 PM EST An experienced Editor representing Canada via ScreenRant's Team Anime, J.R. has been reading manga since the first printing of Shonen Jump in North America. This passion drove him to write about anime, manga, and manhwa, having recently served as Lead Anime Editor for ComicBook.com. Anime underwent an explosive wave of new mainstream appeal across the current decade, with Demon Slayer: Kimetsu no Yaiba commonly shortlisted among the most, if not the singular, most influential catalyst. Its prestige quality inspired long-standing studios to reconfigure to seasonal models, and its movies have been enormously profitable to the point of standing among multiple years' highest-grossing films worldwide. It's a juggernaut of a franchise, but as it cruises toward its finale with the Infinity Castle movies, the last thought on most fans' minds is how this clearly finite story will last in its post-Infinity Castle era. But according to Bloomberg News via The Japan Times, it seems that president of Sony Music Entertainment Japan and Aniplex chairman Atsuhiro Iwakami has idealistic plans for its future as a franchise. Pointing to anime as a "gold mine for sprawling entertainment franchises", Iwakami made a fascinating comment, particularly about Demon Slayer and wanting to "make this last" for decades to come, with fans understandably alarmed by his reported intent for it to go for 100 years. Demon Slayer's anime and overall main story simply don't have enough story to last much longer, so it's important to grasp the full context of what Iwakami said. Demon Slayer Won't Have 100 Years Of Anime, But It Still Has Life In It Beyond the eye-grabbing headlines about wanting Demon Slayer, a manga running just over 200 chapters, to last 100 years as an anime franchise, Iwakami's exact words point to this being more idealistic than a firm goal. In fact, Iwakami's precise quote from the Bloomberg interviews points more to Demon Slayer as a successful franchise he simply wants to cross the generational gap like other big hits. “With Demon Slayer, it is our intent to make this last 10 or 20, if not 50 to 100 years [...] We want to make sure we’re part of creating the type of franchise that can withstand decades.” With a series less than a third the original length of legendary hits like Naruto yet having the potential to outpace it in print manga sales, Demon Slayer has remained immensely popular and a safe bet for more projects. But right away, fans should not assume a future in which Sony Music Entertainment Japan or Aniplex, its anime planning/production/distribution house, actively plans to make 100 years of Demon Slayer anime. Depending on who one asks, Demon Slayer as an anime franchise will have concluded a healthy 10 years by the time it releases its second and likely its third film, with a perfectly rewatchable backlog for those still holding back. After all, Naruto's anime has continued to dominate Netflix viewership stats nearly a decade since its main series conclusion. Despite a lower episode count, little is keeping Demon Slayer from similarly sustainable popularity. While there are certainly still gaps to be filled in, such as completing the current unfinished decade of anime since Demon Slayer's Ufotable adaptation starting in 2019, or numerous spin-off manga or light novels. This is more about ensuring Demon Slayer's current popularity carries into the future. This can hypothetically include additional content like a live-action project to engage viewers outside the usual demographics, much like Netflix's One Piece. But since Sony doesn't hold foundational IP control, with Demon Slayer and other examples Iwakami points to like One Piece and Dragon Ball belonging to Shueisha, additional solutions are being considered. Sony & Aniplex Exec Expands On Potential To Create Long-Lasting Franchises Custom Image by Hannah Diffey Beyond finishing Demon Slayer's finale film trilogy, the potential to expand its already vast streaming opportunities (primarily through Crunchyroll) alongside "games, music, merchandise, and live experiences" stands as a draw should they control the underlying IP. Hayate Inc., Sony's new planning and production company is working on upcoming manhwa adaptations like The Remarried Empress, The Boxer, and SSS-Class Revival Hunter, in addition to projects based on Sony property like Ghost of Tsushima. Anime like these act as proof they want to continue adapting popular content, while pledging a stake in more original content. But to control more of the IP beyond anime, Iwakami recognizes the hurdles. For Demon Slayer and other hit Weekly Shonen Jump projects, Shueisha stands in the way, with Bloomberg's interview going over the sheer fact that buying the publisher, or becoming one of its largest shareholders, is a complicated matter due to Japanese companies frequently being "competitors and collaborators at the same time". It's not necessarily going to mean a similar deal to that with Kadokawa in 2024-2025 per Benzinga. But in the interest of having greater autonomy over proven, successful franchises, Iwakami confirms it'd be welcome if the opportunity presents itself. “So it’s not necessarily the case that just because we want to buy something, we can actually make that happen. But if timing and chance align, we would certainly be open to entertaining different types of M&A.” Anime is the fastest-growing storytelling medium in the current era, with Shueisha's properties demonstrably seen as their most profitable, popular options. Sony appears intent on creating original franchises that can have lasting popularity with Aniplex's Demon Slayer anime as a solid case study both for investing more into other Shueisha IP. But they appear intent on making more of their own projects to get access to additional sources of revenue like merchandise, video game adaptations, and more.
