In a blaze of anticipation, the first full trailer for the first Demon Slayer: Kimetsu no Yaiba – Infinity Castle film has been released, offering a thrilling glimpse into the epic conclusion of the beloved anime saga. Released on June 28, 2025, via Aniplex’s official YouTube channel, the trailer showcases the stunning animation of studio ufotable and introduces two new theme songs by renowned artists LiSA and Aimer. Titled Akaza’s Return, this film marks the beginning of a trilogy that will adapt the final battles of Koyoharu Gotoge’s manga, setting the stage for a monumental clash between the Demon Slayer Corps and the demonic forces of Muzan Kibutsuji.
The trailer teases breathtaking action sequences, with Ufotable’s signature vibrant visuals and fluid choreography bringing the manga’s climactic battles to life. Key moments highlight Tanjiro, voiced by Natsuki Hanae, alongside Hashira like Giyu Tomioka (Takahiro Sakurai), Sanemi Shinazugawa (Tomokazu Seki), and Mitsuri Kanroji (Kana Hanazawa), as they prepare to confront the Upper Rank demon Akaza, voiced by Akira Ishida, whose return is a focal point of the film’s narrative.
Accompanying the trailer, a striking new key visual for the first Demon Slayer: Kimetsu no Yaiba – Infinity Castle film has been unveiled, and it features a menacing look at Akaza.
Adding emotional depth to the visual spectacle are the new theme songs unveiled in the trailer. Aimer’s haunting Taiyō ga Noboranai Sekai (A World Where the Sun Never Rises) sets a somber tone, reflecting the dire stakes of the Demon Slayer Corps’ mission. Meanwhile, LiSA’s powerful Zankoku no Yoru ni Kagayake (Shine in the Cruel Night) delivers an uplifting energy, echoing her iconic contribution to the series with Gurenge from Season 1. Both tracks, set to release on global streaming platforms on July 18, 2025, promise to resonate with audiences, enhancing the emotional weight of the trilogy’s opening chapter. The score, composed by Go Shiina and Yuki Kajiura, further amplifies the trailer’s intensity, with hints of an instrumental version woven into the latter half, teasing fans with its cinematic grandeur.
Directed by Haruo Sotozaki, with character designs overseen by Akira Matsushima, the first Demon Slayer: Kimetsu no Yaiba – Infinity Castle film continues ufotable’s tradition of delivering top-tier animation. The film’s production boasts an impressive team, including art directors Koji Eto, Masaru Yanaka, and Yuri Kabasawa, and 3D director Kazuki Nishiwaki, ensuring a visually immersive experience. The narrative picks up directly from the Hashira Training Arc, where the Corps’ elite swordsmen honed their skills for the impending war. As Muzan’s ambush disrupts their preparations, the trailer hints at the psychological and physical trials awaiting Tanjiro and his allies in the labyrinthine Infinity Castle, a surreal battlefield that defies reality itself.
