See the Chainsaw Man Movie Kenshi Yonezu ‘Iris Out’ Music Video

There are new updates on Chainsaw Man - The Movie: Reze Arc now that the film continuing the story of the anime adaptation is about to debut in Japan on September 19, 2025, and that includes a movie poster and the music video for the Kenshi Yonezu “Iris Out” theme song. Both can be seen online. 

“Iris Out” is one of two Kenshi Yonezu songs for Chainsaw Man - The Movie: Reze Arc. The other is a duet with Hikaru Utada. That track is called “Jane Doe.” It hasn’t been released in full yet. However, “Iris Out” is on Apple Music, Spotify, and YouTube Music, in addition to its music video being on YouTube.

Here’s the full music video for “Iris Out” by Kenshi Yonezu, which features characters from Chainsaw Man - The Movie: Reze Arc like Denji, Reze, and Makima. 

As for the movie poster, here’s how that looks:

As a reminder, there will be a way to catch up with the series more quickly. Chainsaw Man – The Compilation: Part 1 and 2 will condense the original anime series down to two movies. That will show up on Crunchyroll in the US and Canada in September 2025. 

Season one of Chainsaw Man is already on Crunchyroll, and the Reze Arc movie will debut in Japan on September 19, 2025 and in US theaters in English on October 29, 2025.
