Bocchi the Rock! is heading back to the big screen — and back in time. The series' official website announced a prequel anime film, subtitled Hoshi no Ashiato, set for 2027, complete with main cast, staff, and a teaser visual.

Shin Wakabayashi directs at CloverWorks, the studio behind the beloved original series. Per Anime Corner, the film will star Nijika and her older sister Seika — a notable shift of spotlight away from Bocchi herself and toward the Ijichi sisters' history before Kessoku Band came together.

The announcement caps a strong run for the franchise, which became a breakout hit on the strength of its anxious-guitarist protagonist and inventive visual comedy. A prequel centered on Seika, the stoic owner of the live house where the band performs, gives the film room to explore backstory the TV series only hinted at.

No release date beyond the 2027 window has been confirmed. Expect casting and staff details to firm up as production ramps.
