The latest trailer for Chainsaw Man – The Movie: Reze Arc has sent ripples of excitement through the anime community, revealing that musical powerhouses Kenshi Yonezu and Hikaru Utada will collaborate on the film’s ending theme song, “JANE DOE.” Kenshi Yonezu will also contribute the film’s main theme song, titled “IRIS OUT.” The highly anticipated movie is set to premiere in Japanese theaters on September 19, 2025, with international releases following closely, beginning September 24 in over 80 countries and reaching the United States and the United Kingdom on October 29.
A Musical Collaboration of Legends
The announcement of Kenshi Yonezu and Hikaru Utada joining forces for the Reze Arc movie’s ending theme, “JANE DOE,” marks a significant moment for fans. Yonezu is no stranger to the Chainsaw Man universe, having previously performed the television anime’s electrifying opening theme, “KICK BACK.” His continued involvement, alongside the legendary Hikaru Utada, promises a powerful and emotionally resonant musical backdrop for the film. The combination of these two prominent artists suggests a track that will capture the intricate and often somber tones of the “Reze Arc.”
In addition to the collaborative ending theme, Kenshi Yonezu is also responsible for the movie’s main theme song, “IRIS OUT.” This dual contribution from Yonezu further solidifies his integral role in the Chainsaw Man anime’s soundscape, building on the success of his previous work for the series.
Delving into the Reze Arc
Chainsaw Man – The Movie: Reze Arc directly adapts the popular “Reze Arc” from Tatsuki Fujimoto’s critically acclaimed manga, a storyline often affectionately referred to by fans as the “Bomb Girl Arc.” The film serves as a direct sequel to the first season of the Chainsaw Man anime, continuing the tumultuous journey of Denji.
The story picks up after Denji’s experiences as a Public Safety Devil Hunter and a member of Tokyo Special Division 4. The arc introduces Reze, a mysterious girl Denji encounters after a date with Makima, who quickly becomes central to the narrative, leading to an explosive “love triangle” hinted at in previous trailers. The film is considered essential viewing for fans, as it is canon to the anime’s overarching story, much like Demon Slayer: Mugen Train served as a continuation before its subsequent season.
Production and Global Release
MAPPA, the renowned animation studio behind the first season of the Chainsaw Man anime, is producing Chainsaw Man – The Movie: Reze Arc. The film sees the return of key staff members from the TV series, ensuring continuity in its highly praised animation and storytelling. Tatsuya Yoshihara, who worked as a storyboarder, key animator, and episode director for the TV anime, steps into the director’s role for the movie. Hiroshi Seko returns as the screenwriter, and Kensuke Ushio is once again composing the music. Reina Ueda has been cast as the voice of Reze.
The film’s global release strategy aims for a wide reach. Following its Japanese premiere on September 19, 2025, Sony Pictures Entertainment (SPE) has acquired worldwide theatrical rights, with Columbia Pictures handling distribution. The movie will begin its international rollout on September 24 in over 80 countries, including the Philippines, before hitting theaters in the United States and the United Kingdom on October 29.
