Yonezu had previously provided "Kick Back" as the opening theme for the Chainsaw Man anime series, which became the first Japanese-language song to earn a Gold certification from the RIAA. The release date of "Iris Out" was set for September 24 as a double A-side single with an untitled track. On August 14, the untitled song was revealed as "Jane Doe", a collaboration with Hikaru Utada, and was confirmed as the film's ending theme.
Release
The double A-side single "Iris Out" / "Jane Doe" was released on September 24, 2025, in three variants: regular, Iris Out edition, and Jane Doe edition. The Iris Out edition includes an acrylic stand and a Polaroid photo of the character Reze; the Jane Doe edition contains a DVD of the "Kick Back" music video and a live performance. First press bonuses for all variants provide a serial number for a lottery to win tickets to Yonezu's 2026 Ghost Tour.
