Get ready for a dream team-up! Japanese music titans Kenshi Yonezu and Hikaru Utada have officially announced their collaboration on a new track, "JANE DOE," which is set to be the ending theme for "Chainsaw Man The Movie: Reze Arc." Yonezu penned the lyrics and composed the music, with Utada lending her vocals, continuing the creative team behind the film's main theme, "IRIS OUT."
A teaser video for the ending theme, featuring an intro from "JANE DOE," has already dropped, alongside brand-new artist photos of the duo and single cover art personally drawn by Kenshi Yonezu, giving fans an early taste of the track's vibe.

The "IRIS OUT Edition" features special pouch packaging, including a polaroid photo of Reze drawn by Yonezu and an acrylic stand. Meanwhile, the "JANE DOE Edition" comes in a shattered-design storage box, containing a CD and DVD which includes the official trailer for "Chainsaw Man The Movie: Reze Arc," the "KICK BACK" music video, and live performance footage. This dream collaboration has anime fans buzzing and music lovers eagerly anticipating its release.
