The Ultimate Music-Cinema Fusion Is Here

Brace yourselves, Chainsaw Man fans—this one’s massive.

The highly anticipated Chainsaw Man – The Movie: Reze Arc is coming to the big screen with more than just blood, devils, and battles. It’s also bringing with it a rare, high-voltage musical collaboration between two of Japan’s most revered artists: Kenshi Yonezu and Utada Hikaru.

Yes, you read that right. Utada Hikaru—voice behind “First Love,” “Automatic,” and the Kingdom Hearts soundtrack—will lend their iconic vocals to the film’s hauntingly emotional ending theme, “Jane Doe.” And the song’s composer and producer? None other than Kenshi Yonezu, the creative genius behind Chainsaw Man’s first anime opening theme, the explosive “Kick Back.”

But that’s not all. Yonezu is also delivering the movie’s opening theme, “Iris Out”, a high-energy track that sets the stage for the intense drama to follow.

Watch the Teaser for “Jane Doe”

From Anime to Big Screen: Chainsaw Man Evolves

This isn’t just a musical event—it’s a cinematic one. For the first time ever, Chainsaw Man charges into cinemas in a feature-length film format with Reze Arc. It promises to be a visually arresting and emotionally charged continuation of the hit anime series.

Opening in Philippine cinemas on September 24, the film is directed by Tatsuya Yoshihara and produced by animation powerhouse MAPPA. It adapts the next major story arc from Tatsuki Fujimoto’s critically acclaimed manga series.

The Story So Far: Who’s Reze? Why Does She Matter?

In case you need a refresher—Chainsaw Man follows Denji, a down-and-out devil hunter who, after a brutal betrayal, fuses with his devil-dog Pochita to become the titular Chainsaw Man.

In Reze Arc, Denji’s violent world is shaken once again by the appearance of a mysterious girl named Reze. Sweet, intriguing, and not what she seems, Reze draws Denji into his most complicated—and emotional—battle yet. And yes, it’s personal.

This time, it’s not just about surviving devils. It’s about heartbreak, betrayal, and the quiet moments between the chaos.

“Jane Doe”: A Song for the Soul

Released alongside the film on September 24, the song “Jane Doe” is poised to become an anthem for Chainsaw Manfans. With lyrics written and produced by Kenshi Yonezu, and vocals delivered by Utada Hikaru, it’s an emotionally layered ballad that mirrors Reze’s tragic story arc.

Even the teaser clip—just a few seconds long—has left fans breathless. With Utada’s signature ethereal voice floating over Yonezu’s cinematic production, “Jane Doe” promises to be as unforgettable as the film itself.

“Iris Out”: Opening with Impact

On the flip side, Yonezu’s “Iris Out” delivers the gut-punch energy fans expect from a Chainsaw Man opening theme. Fierce, emotionally raw, and sonically bold, the track will set the tone right from the opening frame.

Together, “Iris Out” and “Jane Doe” will be released as a double A-side single on September 24, available in multiple editions. Collectors can look forward to exclusive DVD content, acrylic stands, and even lottery entry tickets for Yonezu’s upcoming Ghost Tour 2026.

Why This Collaboration Matters

This is more than just a musical crossover. It’s the meeting of two creative forces who’ve each shaped Japanese music in their own era.

Utada Hikaru broke ground in the late ’90s and early 2000s, merging J-pop with Western R&B and emotional songwriting that influenced an entire generation. Kenshi Yonezu, meanwhile, revolutionized modern Japanese pop with his experimental sounds, poetic lyrics, and striking visual storytelling.

Together, they’re not just making music—they’re making history.
