Kroi announced that their new song “SPIN” will serve as the opening theme for the anime STEEL BALL RUN JoJo’s Bizarre Adventure. The news was revealed on September 23 during the sold-out final show of Kroi Live Tour 2026 “JUNGLE” at Zepp Haneda, where the band also announced the song’s upcoming digital and CD releases, as well as Kroi Live Tour 2027.

The announcement came as a surprise during the encore of the tour finale. As cheers filled the venue, a video suddenly appeared on a screen onstage, revealing that Kroi would perform the opening theme for STEEL BALL RUN JoJo’s Bizarre Adventure. The crowd erupted in excitement, and as soon as the video ended, bassist Masanori Seki launched into a sharp bassline as the band gave the first-ever live performance of “SPIN.”

For this performance only, fans in the attendance were specifically permitted to film the song, and footage from the performance has since been generating excitement across social media.

“SPIN” will be available across major streaming and download platforms beginning September 24 at 12:00 a.m. JST. The creditless opening video for STEEL BALL RUN JoJo’s Bizarre Adventure will also be released on YouTube and other platforms, offering fans an early glimpse into the world of the anime ahead of its September 25 streaming release.

 

Speaking about creating “SPIN” for STEEL BALL RUN JoJo’s Bizarre Adventure, Kroi shared:

“We are Kroi, and we were honored to work on the opening theme for STEEL BALL RUN JoJo’s Bizarre Adventure.

When we were first approached about this project, we were so excited we practically jumped for joy.

From there, we went through a lot of trial and error as we worked on how to express the series’ epic world of a cross-continental race across North America through music.

We’ve been creating songs with a sandy theme for several years now, and we thought we could put the sensibilities we’ve cultivated through that experience to good use this time as well.Centered around a sound reminiscent of Ennio Morricone and The Ventures that evokes Westerns, we finished this track by blending in various musical styles we’ve explored over the years, such as funk, soul, and hip-hop.

We can’t help but feel a personal connection to the unique and unparalleled world of JoJo, born from the intersection of diverse cultures.

We’re truly delighted to have been able to participate in this wonderful project.
Please enjoy our song “SPIN” by Kroi along with the anime.”

 

A physical CD release of “SPIN” is also set for October 28. The release will feature newly illustrated artwork from STEEL BALL RUN JoJo’s Bizarre Adventure on its cover, with retailer-exclusive purchase bonuses also available at participating stores.

 

Alongside the release announcements, the band unveiled Kroi Live Tour 2027, a nationwide tour spanning 15 cities across Japan beginning in June 2027. With “SPIN” marking the beginning of another exciting chapter for the band, Kroi is set to bring their evolving sound to stages across the country.

Introduction

It’s 1890, in America, the Steel Ball Run — the first horse racing championship across the North American continent — was about to begin. Spanning around 4,000 miles, the race offered 50 million dollars as the winning prize.

Johnny Joestar, once being hailed as a genius jockey, is now paralysed and lost in despair.

He finds hope in the mysterious phenomena caused by Gyro Zeppeli, an outlaw aiming to win the race, and determines to participate in the Steel Ball Run Race.

Each having their own goal in mind, the two form an alliance and set foot upon the gruelling adventure and race.
