What is Demon Slayer: Infinity Castle Arc (Movie)?

“Demon Slayer: Infinity Castle Arc – Part 1” is the anime movie adaptation of the final arc “Infinity Castle” from Koyoharu Gotouge’s hit manga “Demon Slayer.” This installment continues directly from the TV series “Swordsmith Village Arc,” finally depicting the final battle against Muzan Kibutsuji in an intense storyline.

The movie is scheduled to release nationwide in theaters on Friday, July 18, 2025, with IMAX screenings also confirmed. It will showcase battles and psychological drama that could not be fully expressed in the TV anime, with high-quality animation and sound design set to overwhelm audiences.

This project is planned as a trilogy, with Part 1 covering the early stages after entering Infinity Castle and the clashes between the Hashira and the Upper Rank demons. Notably, major characters like Giyu Tomioka and Gyomei Himejima will take the spotlight.

It will also feature exclusive scenes, cuts, and ending sequences not available in the TV version. Although future TV broadcasts are possible, initially, the film can only be experienced in theaters, making it a valuable opportunity.
