The first full trailer for Demon Slayer: Kimetsu no Yaiba — Infinity Castle, opener in a three-part finale to the hit anime, premiered online Friday via Crunchyroll and Sony Pictures, delivering rapid-fire shots of Tanjiro and the Hashira battling Upper Rank demons inside the shifting fortress. The footage capped a month of teasers that leaked ahead of schedule and were later confirmed during a Fuji TV special broadcast.
Studio Ufotable’s trailer also unveiled new theme songs—“Shine in the Cruel Night” by LiSA and “A World Where the Sun Never Rises” by Aimer—continuing the franchise’s chart-topping partnership with both singers. Producer Aniplex said the music signals “the beginning of the end” for the property’s six-year television run.
The first film opens in 443 Japanese cinemas on 18 July before launching across Southeast Asia from 14 August and rolling into North America, the United Kingdom and more than 40 additional territories on 12 September. Crunchyroll will distribute under Sony Pictures Releasing, a rollout the company calls “unprecedented in scale for anime.” GamesRadar notes the trilogy could continue through 2027, replacing a planned fifth TV season entirely.
Director Haruo Sotozaki and Ufotable adapt the manga’s concluding Infinity Castle and Sunrise Countdown arcs, which follow the Hashira Training storyline into Muzan Kibutsuji’s stronghold. Polygon warns the stakes are lethal, saying “beloved characters” may fall before the saga closes.
Analysts are watching to see whether Infinity Castle can rival 2020’s Mugen Train, which grossed $507 million worldwide. Box-office forums predict a $75–100 million North-American opening, citing the post-pandemic surge in theatrical anime. Recent Crunchyroll Anime Awards wins and Sony’s wider cinema strategy are expected to amplify demand.
Beyond the core trilogy, Ufotable has produced etiquette shorts and crossover promos that highlight the franchise’s marketing clout ahead of release. Analysts say that brand power, coupled with wide premium-format bookings, positions the opening chapter as a late-summer tent-pole in Japan and a fall anchor for global box offices.
