Steel Ball Run Releases Opening Video Featuring Kroi’s “SPIN”

Steel Ball Run: JoJo’s Bizarre Adventure released its creditless opening sequence on September 24 in Japan, confirming Kroi’s “SPIN” as the anime’s opening theme. The video arrived through the franchise’s official channels shortly before the next run of episodes begins on Netflix on September 25.

What the opening announcement confirms

The official JoJo portal identifies “SPIN” as the opening theme for Steel Ball Run and credits Kroi with writing and performing the song. The creditless video presents the finished opening sequence without the usual on-screen staff credits, giving the animation and music their own dedicated showcase. Its release followed an official notice that set the video’s premiere for midnight on September 24 in Japan.

The portal’s announcement paired the song title and artist credit with links to the official video and distribution services. It labels the upload as the non-credit opening movie, distinguishing it from a character trailer or episode preview. The sequence therefore serves as the official opening presentation for the upcoming run.

“SPIN” also received a digital release on September 24. The official music page lists the main song and an instrumental version. Cover artwork for the release was unveiled alongside the theme announcement, tying the song’s standalone launch directly to its role in the anime. The portal notes that availability through the listed distribution services varies by country and region.

Kroi described the assignment as an effort to translate Steel Ball Run’s world and its transcontinental North American race into music. In the band’s official comment, the members pointed to classic Western-inspired soundscapes associated with Ennio Morricone and The Ventures, then explained that they blended those influences with funk, soul, and hip-hop. The result was created specifically for the series rather than selected from an existing Kroi release.

How “SPIN” leads into the next stages

The opening video arrives immediately before Steel Ball Run resumes. The 2nd and 3rd Stage episodes are scheduled to begin streaming worldwide on Netflix on September 25, with new episodes set for Fridays. That makes the creditless sequence a direct preview of the opening presentation viewers will encounter as the race continues.

The official music page also situates the theme in Kroi’s catalog. The band formed in February 2018 and made its major-label debut with the album LENS in June 2021. It later staged its first solo concert at Nippon Budokan in January 2024 and completed its first arena tour in January 2026, before taking on Steel Ball Run.

The release separates two pieces fans can now access before the new episodes: the creditless opening animation and the song itself. The official video supplies the sequence without staff credits, while the digital release provides the vocal recording alongside an instrumental arrangement.

With “SPIN” now confirmed and the creditless opening publicly available, the next scheduled milestone is the September 25 start of Steel Ball Run’s 2nd and 3rd Stages on Netflix.
