Chainsaw Man The Movie: Reze Arc, one of the most highly anticipated anime films of the year, has heightened excitement with the release of the official music video for its theme song, IRIS OUT, by acclaimed Japanese musician Kenshi Yonezu. The video, which premiered today, showcases Yonezu's signature blend of emotive lyrics and dynamic soundscapes, perfectly complementing the intense narrative of the Chainsaw Man franchise.
IRIS OUT marks Yonezu's second collaboration with the Chainsaw Man series, following his hit opening theme KICK BACK for the television anime adaptation. The song captures themes of intense emotion, obsession, and transformation, with lyrics that evoke a sense of chaotic affection and existential longing. Partial excerpts from the lyrics include lines such as I love you like crazy! and The way you look up at me is so adorable, it just kills me—it's almost illegal, alongside In this world right now, you're my one-and-only perfect answer. These phrases highlight the track's raw energy, aligning seamlessly with the story's dark and visceral tone.
The single's cover art, newly illustrated by Yonezu himself, features the character Reze, the enigmatic Bomb Devil hybrid central to the film's arc. This artistic touch adds a personal layer to the release, emphasizing Yonezu's deep involvement in the project. The music video itself, while details on its visual narrative remain focused on the song's delivery, integrates elements that resonate with the movie's themes, drawing viewers into the world of Denji and his devil-hunting exploits.
What is Chainsaw Man The Movie: Reze Arc about?
Chainsaw Man The Movie: Reze Arc adapts the popular Bomb Girl arc from Tatsuki Fujimoto's manga series Chainsaw Man. The story follows Denji, a young devil hunter fused with the Chainsaw Devil, as he navigates a life of chaos and violence. His world shifts dramatically when he meets Reze, a seemingly ordinary girl who hides a dangerous secret as the Bomb Devil hybrid. Their encounter spirals into a volatile mix of romance, betrayal, and explosive confrontations, challenging Denji's understanding of trust and survival. Produced by Studio MAPPA, the film delivers stunning animation and intense action, with director Ryu Nakayama and scriptwriter Hiroshi Seko returning to maintain the series' signature gritty and emotional tone.
The release of the IRIS OUT music video coincides with broader announcements for Yonezu's 16th single, titled IRIS OUT / JANE DOE. The double A-side single features JANE DOE as the ending theme for the movie, a collaboration with renowned artist Hikaru Utada. Digital distribution for the single begins on September 22, 2025, with physical CD copies available in stores starting September 24, 2025. Additionally, purchasers of the CD will gain access to ticket pre-sales for Yonezu's upcoming 2026 TOUR / GHOST, with the application period running from September 22 to September 28, 2025.
This musical contribution underscores Yonezu's growing influence in the anime industry, where his tracks have consistently elevated the emotional impact of major productions. The integration of IRIS OUT into the film's main trailer, released earlier this year, has already generated buzz for its pulsating rhythm and thematic synergy with the on-screen action.
Chainsaw Man The Movie: Reze Arc is set to premiere in theaters nationwide in Japan on September 19, 2025, with international releases following in October 2025. Fans eager to revisit the origins of the series can stream the first season of the Chainsaw Man television anime on Crunchyroll, where it is available with both subtitles and dubbed options in multiple languages.
