New Chainsaw Man: Reze Arc music video offers the best look yet at the film’s fight scenes

The official music video for “IRIS OUT,” the main theme song for the upcoming film Chainsaw Man – The Movie: Reze Arc by the artist Kenshi Yonezu, has been released.
The new video was posted to the artist’s official YouTube channel, following the movie’s World Premiere event which was held in Tokyo on the 15th of September.

The new music video is composed entirely of footage from the main feature film.
It showcases a number of highlight scenes from the movie, which tells the story of the protagonist Denji’s brief, youthful romance with the mysterious girl, Reze, and the intense battles that follow.

A warning has been issued that the music video contains some spoilers for the main story of the film.

At the World Premiere event, a special video message from Kenshi Yonezu was shown.

In it, he revealed that he was so impressed by the “incredible talent and love” that went into the film’s promotional trailer that he asked if he could use its footage to create the music video, and even incorporated some of its sound effects into the final song.
To celebrate the release of the new song and the upcoming release of the film’s ending theme, “JANE DOE,” which is a collaboration between Kenshi Yonezu and the singer Hikaru Utada, a special live audio talk show has been announced.
The “Kenshi Yonezu Spotify Listening Party” will be a real-time, exclusive event for Spotify Premium users.
The listening party is scheduled to be streamed on Monday, the 22nd of September, at 10:00 PM Japan Standard Time.

The movie itself is scheduled to be released in Japan on Friday, the 19th of September, 2025.
The film is highly anticipated by fans of the series, and major cinema chains in Japan are gearing up for its release, with some set to stock an exclusive Chainsaw Man themed popcorn bucket.
