The highly anticipated first film in the Demon Slayer: Kimetsu no Yaiba – Infinity Castle trilogy has unveiled its latest trailer, exciting fans with new footage and the announcement of theme songs performed by beloved artists Aimer and LiSA. This cinematic event marks a pivotal moment for the globally acclaimed anime franchise as it embarks on adapting the climactic final arc of Koyoharu Gotouge’s manga.
A Musical Reunion: Aimer and LiSA Return
The revelation that both Aimer and LiSA are contributing theme songs for the Infinity Castle film has resonated deeply with the Demon Slayer fanbase. These artists have become synonymous with the series’ powerful soundtracks, consistently delivering tracks that amplify the anime’s emotional depth and action sequences.
LiSA, a cornerstone of the Demon Slayer musical landscape, will perform the song “Zankoku no Yoru ni Kagayake” (“Shine in the Cruel Night”). Her previous contributions include the iconic first season opening theme “Gurenge” and the award-winning “Homura” for Demon Slayer: Kimetsu no Yaiba – The Movie: Mugen Train. “Gurenge” became a cultural phenomenon upon its release in 2019, while “Homura” further cemented her integral role in the franchise’s sound.
Aimer, who debuted in the franchise with the Entertainment District Arc, will perform “Taiyō ga Noboranai Sekai” (“A World Where the Sun Never Rises”). Her previous tracks for Demon Slayer, “Zankyou Sanka” (opening theme) and “Asa ga Kuru” (ending theme) for the Entertainment District Arc, were widely praised for their intensity and emotional resonance. Both new theme songs, “Taiyō ga Noboranai Sekai” by Aimer and “Zankoku no Yoru ni Kagayake” by LiSA, will be available on global streaming platforms starting July 18, 2025, the same day as the film’s Japanese premiere.
The Infinity Castle Arc: A Trilogy to Conclude an Epic Saga
The Demon Slayer: Kimetsu no Yaiba – Infinity Castle film is the first installment in a three-part movie series designed to adapt the manga’s final arc. Unlike previous compilation films such as To the Swordsmith Village and To the Hashira Training, this trilogy will be feature-length adaptations, providing a comprehensive and faithful retelling of the manga’s climactic conclusion. This format choice reflects the arc’s extensive content and dramatic pacing, akin to the highly successful Mugen Train film.
The story plunges the Demon Slayer Corps and Hashira into the titular Infinity Castle, a surreal, shape-shifting labyrinth controlled by the primary antagonist, Muzan Kibutsuji. The narrative follows the events immediately after the “Hashira Training Arc,” where the Demon Slayer Corps members and Hashira were undergoing rigorous preparation for their ultimate confrontation with Muzan. When Muzan unexpectedly attacks the Ubuyashiki Mansion, Tanjiro and the Hashira are pulled into this mysterious dimension, setting the stage for the final, arduous battle between humanity and demons.
The first film, officially titled Demon Slayer: Kimetsu no Yaiba Infinity Castle – Part 1: Akaza Returns (or Akaza Sairai), promises to delve deeply into character arcs, intense battles, and long-awaited revelations. The recently released main trailer showcases these major battles, including a teased iconic fight involving Giyu Tomioka, Tanjiro Kamado, and Akaza.
