The highly anticipated “Demon Slayer: Kimetsu no Yaiba Infinity Castle First Movie” has unveiled its main trailer, alongside the exciting revelation that acclaimed artists Aimer and LiSA will contribute the film’s theme songs. This cinematic event marks the beginning of a trilogy that will adapt the climactic Infinity Castle Arc, the final saga of Koyoharu Gotouge’s immensely popular manga series.
A Musical Reunion for a Climactic Arc
Fans of the Demon Slayer franchise will recognize both Aimer and LiSA as iconic voices intrinsically linked to its previous successes. LiSA, a long-standing collaborator, famously performed the first season’s opening theme “Gurenge” and the record-breaking “Homura” for “Demon Slayer: Kimetsu no Yaiba – The Movie: Mugen Train.” Her contributions continued with the “Mugen Train Arc” TV adaptation, providing “Akeboshi” and “Shirogane.” Aimer made her indelible mark on the series with “Zankyosanka” and “Asa ga Kuru” for the “Entertainment District Arc,” which became fan favorites.
For the “Infinity Castle First Movie,” Aimer will perform “A World Where the Sun Never Rises” (Japanese title: “Taiyō ga Noboranai Sekai”), while LiSA will deliver “Shine in the Cruel Night” (Japanese title: “Zankoku no Yoru ni Kagayake”). Both singles are slated for release on global streaming platforms on July 18, 2025, or July 19, 2025, in some regions. This dual theme song approach underscores the monumental scale and dramatic weight of the upcoming film.
The Dawn of the Final Battle
The “Demon Slayer: Kimetsu no Yaiba Infinity Castle First Movie,” also formally known as “Demon Slayer: Kimetsu No Yaiba The Movie: Infinity Castle Part 1 Akaza Returns,” premiered its full trailer on June 28, 2025. This film is not a compilation, but a dedicated feature-length adaptation designed to capture the arc’s intense content and pacing, much like the highly successful “Mugen Train” film. A new key visual featuring the formidable Upper Rank Three demon Akaza was also released, further hyping the impending battles.
The film is set to delve into the heart of the Infinity Castle, the stronghold of the series’ primary antagonist, Muzan Kibutsuji, and his remaining powerful Upper Rank demons. Following the “Hashira Training Arc,” where the Demon Slayer Corps members and Hashira underwent rigorous preparation, the narrative plunges them into a mysterious space under Muzan’s influence, leading to the ultimate confrontation. The trailer teases several pivotal confrontations, including Zenitsu Agatsuma’s highly anticipated battle against Kaigaku, Shinobu Kocho’s fight against Douma, and Tanjiro Kamado’s revenge match against Akaza, the demon responsible for Flame Hashira Kyojuro Rengoku’s death during the “Mugen Train” arc. These battles are expected to showcase Ufotable’s renowned animation prowess, promising breathtaking visual spectacles.
Global Release and Anticipation
“Demon Slayer: Kimetsu no Yaiba Infinity Castle First Movie” is slated for a theatrical release in Japan on July 18, 2025, opening on a record-breaking 443 screens across the country.

This trilogy of films is poised to conclude the Demon Slayer anime saga on the big screen, a testament to the franchise’s monumental success and its impact on the global entertainment landscape.
