Demon Slayer: Kimetsu no Yaiba – To the Hashira Training

This film assembles the final installment of the third television season together with the premiere episode of the fourth, presenting them as a single theatrical event. Produced by Ufotable and directed by Haruo Sotozaki, it adapts material from Koyoharu Gotoge's manga.

It reached Japanese cinemas on February 2, 2024, with international showings following that same month. The release was organized as a second world tour, bringing the feature to audiences in multiple countries within the year. The ending theme, titled Mugen, was performed by My First Story featuring Hyde, while the film carried no opening theme.

Following the revelation that Nezuko Kamado has gained immunity to sunlight, Muzan Kibutsuji sees his long-held goal of becoming truly immortal drawing within reach. Sensing that a decisive clash is approaching, the Demon Slayer Corps begins a coordinated regimen known as the Hashira Training, in which each of the Hashira drills the rank-and-file slayers to sharpen their endurance and combat skills during a tense lull in demon activity.

For Tanjiro Kamado, the program offers a valuable opportunity both to grow stronger and to come to know the Corps' most powerful swordsmen more closely. With humanity facing the strongest demon in its history and able to rely only on its own resolve, the story stresses the need for everyone to stand united ahead of the coming war.

As a compilation built from broadcast episodes rather than newly produced content, the feature functioned chiefly as a bridge between the third and fourth seasons and as a way to introduce the start of the new season to theatrical audiences worldwide. Its international tour format extended that preview to viewers across many countries. The voice cast included Natsuki Hanae as Tanjiro and Akari Kito as Nezuko, with Toshihiko Seki returning as Muzan.
