Japanese boy group BE:FIRST have released their new single, “BRUCE WAYNE,” featuring Alabama rapper Flo Milli and Atlanta producer-artist ATL Jacob. Available now across digital streaming platforms, the track arrives with an official music video and offers the first major look at the group’s next international chapter.
“BRUCE WAYNE” brings BE:FIRST’s gritty, high-energy style together with Flo Milli’s playful confidence and sharp delivery. ATL Jacob provides the hypnotic production underneath the collaboration, creating a sound that connects Japanese pop performance with the force and personality of contemporary Southern hip-hop.
The record was developed by a strong creative team that includes Starrah, Taylor Ross, ATL Jacob, Flo Milli and BE:FIRST executive producer SKY-HI. Their combined involvement gives the song an international identity without taking away from the versatility and chemistry that BE:FIRST have built since forming in 2021.
“As a producer, I love being put in environments that are unfamiliar. It forces you to listen differently, create differently, and ultimately make something that feels fresh and genuine,” ATL Jacob said. His approach helped shape a collaboration that feels naturally shared between the artists rather than forcing either side to abandon its musical identity.

The single serves as the first major introduction to BE:FIRST’s upcoming global EP, WATCH ME, scheduled for release on September 18. The project will include production from Tommy “TBHits” Brown and ATL Jacob, alongside a guest appearance from multiplatinum rapper BIA, expanding the group’s growing connection to the international music industry.
Formed through SKY-HI’s reality audition program THE FIRST, BE:FIRST consists of SOTA, SHUNTO, MANATO, RYUHEI, JUNON and LEO. The group combines dance, pop, hip-hop and R&B while maintaining a performance style that has helped it earn 12 No. 1 singles on the Billboard Japan Hot 100 and build a dedicated global fanbase known as BESTY.
Flo Milli brings additional momentum to the release following a career that has produced more than 4 billion streams. Her energetic appearance gives “BRUCE WAYNE” a bright and unpredictable edge, while ATL Jacob’s experience creating records for artists including Future, Drake, Nicki Minaj, Travis Scott and Lil Baby strengthens the song’s hip-hop foundation.
The collaboration will also support BE:FIRST’s wider international push and the upcoming BE:FIRST WORLD TOUR SHOWCASE TOUR 2026: WATCH ME. With the new single now available and the group’s first global EP approaching, “BRUCE WAYNE” positions BE:FIRST for their most ambitious era yet, according to BE:FIRST’s official announcement.
