Hold your Nichirin Blades tight, Demon Slayer fans, because the hype train is roaring! A brand-new trailer for Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle is set to premiere in Japan on May 9, 2025, exclusively at the theatrical re-release of Mugen Train, as announced during the Demon Slayer Festival. This electrifying sneak peek into the first of a trilogy of films adapting the manga’s climactic Infinity Castle Arc has fans buzzing with anticipation. With a Japanese release date locked for July 18, 2025, and global screenings kicking off in September, this trailer is about to ignite the fandom. Here’s why this moment is a game-changer and what you need to know about the Infinity Castle trilogy’s explosive debut!
A Trailer to Set the Stage for the Final Fight
The May 9 trailer premiere, tied to the Mugen Train re-release in Japanese theaters, is a love letter to Demon Slayer’s devoted fans. According to posts from X accounts like @kny_updates, the trailer will be shown to audiences at the end of the screening, making it a must-see event for those in Japan. While the trailer’s contents remain under wraps, previous teasers—like the 2025 Promotion Reel and the CCXP 2024 trailer—hint at what’s coming. Expect chilling glimpses of Muzan Kibutsuji’s labyrinthine Infinity Castle, Tanjiro Kamado’s steely resolve, and the Hashira charging into battle against the Upper Rank demons. The CCXP trailer, with Muzan’s haunting line, “I happen to know what eternity is,” and Ufotable’s jaw-dropping black-and-white visuals, set a tone of raw intensity, per ScreenRant. This new trailer could dive even deeper, showcasing the arc’s epic showdowns and emotional stakes.
The Infinity Castle Arc, covering manga chapters 137–183, picks up where Season 4’s Hashira Training Arc left off. After Ubuyashiki’s sacrificial explosion fails to stop Muzan, the demon lord traps Tanjiro and the Hashira in his shifting fortress, the Infinity Castle. From there, it’s an all-out war as the Demon Slayer Corps battles the Twelve Kizuki’s fiercest demons to reach Muzan and end his reign. GamesRadar+ notes the trilogy will also adapt the Sunrise Countdown Arc (chapters 184–205), wrapping up Tanjiro, Nezuko, Zenitsu, and Inosuke’s journey. With Ufotable’s track record for heart-pounding action and gut-wrenching moments, this trailer is poised to be a pulse-racing taste of the saga’s endgame.
Why This Trilogy Is a Big Deal
Unlike the compilation films To the Swordsmith Village and To the Hashira Training, Infinity Castle is a full-fledged cinematic trilogy, akin to Mugen Train, which became Japan’s highest-grossing film ever with $473 million worldwide, per Forbes. Directed by Haruo Sotozaki and produced by Ufotable, the first film hits Japan on July 18, 2025, with a U.S. and Canada release on September 12, 2025, in IMAX and premium formats, per Crunchyroll. Crunchyroll and Sony Pictures Entertainment are distributing globally (except select Asian markets), ensuring fans from Singapore to Brazil can witness the finale on the big screen. Radio Times reports a UK release on September 12, with other territories like Australia and Mexico starting September 11.
The decision to go theatrical, announced after Season 4’s finale in June 2024, initially sparked debate—some fans wanted a TV Season 5. But Mugen Train’s box office dominance and Infinity Castle’s action-heavy pacing make cinemas the perfect stage. CBR highlights the arc’s emotional weight, with Tanjiro and the Hashira facing their toughest battles yet, diving into backstories like those of Muichiro Tokito and Mitsuri Kanroji. Recent visuals, like Muichiro in “battle mode” shared by @JapanAnimeNews_ on X, tease the Hashira’s fierce resolve, setting up a trilogy that could rival Mugen Train’s records.
A Star-Studded Cast and Ufotable’s Magic
The Infinity Castle films bring back Demon Slayer’s stellar voice cast, led by Natsuki Hanae as Tanjiro, Akari Kitō as Nezuko, Hiro Shimono as Zenitsu, and Yoshitsugu Matsuoka as Inosuke. The Hashira shine with Takahiro Sakurai (Giyu Tomioka), Saori Hayami (Shinobu Kocho), and Tomokazu Sugita (Gyomei Himejima), among others, who performed live readings at the March 1 Corps Gathering Event. Toshihiko Seki’s chilling Muzan is set to steal scenes, especially after his menacing trailer monologue. The English dub, also releasing September 12, ensures global fans can experience the same thrills.
Ufotable’s animation is the real star, with Collider praising their “impeccable” work that makes every fight a visual feast. From the Infinity Castle’s maze-like traps to the Hashira’s breathtaking Breathing Techniques, the trilogy promises cinematic grandeur. A new visual of a crow soaring through the castle, paired with the tagline “The battleground is set,” has fans hyped for Ufotable’s take on the manga’s most intense arc, per Anime Corner. Add in a potential score by Yuki Kajiura and Go Shiina, who crushed it on past seasons, and this is shaping up to be an anime event for the ages.
