The livestream announcing the release date of the first Demon Slayer Infinity Castle movie began with a brief flashback from the prequels. It opened with the anime's premiere and featured Tanjiro's family loss as Nezuko was the only one left behind.
The livestream also introduced each Hashira through the years (as seen in the prequels), each getting a proper introduction through their abilities as the strongest demon slayers. The livestream for the Demon Slayer Infinity Castle anime ended with the reveal of the first movie's release date, on July 18, 2025 (Summer 2025).
Following the announcement, the anime's official X account unveiled a key visual for the First Demon Slayer Infinity Castle anime, featuring the Hashira, the main protagonist group, and the remaining Upper Moon Demons. The movie will be screened across 443 screens in Japan (including IMAX). This number is expected to grow significantly once the first Demon Slayer Infinity Castle movie is released internationally.
As announced during the series' world tour, the Demon Slayer Infinity Castle movie trilogy will be released in 150 countries worldwide. The advanced booking for the movie, only in Japan, will begin on March 7, 2025. Between April 4 and July 3, 2025, the anime's previous movies (the Mugen Train Movie and the compilation ones) will be aired in 33 theaters for a whole week.
