One Piece Heroines: Crunchyroll Releases New Trailer With AiNA’S “The End” Theme Song

Crunchyroll reported on June 23, 2026, that a new trailer for the One Piece Heroines anime has been released. The promotional footage features a theme song performed by Japanese artist AiNA THE END, marking a new musical collaboration for the franchise.

The trailer highlights the visual direction of the project and introduces the vocal contribution of AiNA THE END. According to the report from Crunchyroll, the production focuses on the female characters within the One Piece universe.

Who is AiNA THE END?

AiNA THE END is a Japanese singer and songwriter known for her distinctive husky vocal tone. She first gained prominence as a member of the punk-pop group BiSH, where she contributed to the band’s high-energy performance style before pursuing a solo career.

Since transitioning to solo work, she has established herself in the Japanese music industry through a blend of rock and experimental pop. Her involvement in the One Piece Heroines project follows a trend of the franchise partnering with high-profile, stylistically distinct vocalists to define the mood of its spin-off content.

How does this fit into the One Piece franchise?

The One Piece Heroines anime expands on the franchise’s existing focus on its diverse cast of female characters. While the primary series centers on Monkey D. Luffy and the Straw Hat crew, this project shifts the lens toward the roles and narratives of the women in the series.

This musical approach mirrors the strategy used in One Piece Film: Red, which utilized singer Ado to provide the voice and songs for the character Uta. While Ado’s contribution was characterized by a wide, theatrical range, AiNA THE END’s style offers a different sonic profile that aligns with the specific tone of the Heroines project, according to the trailer’s audio presentation.

The One Piece brand has frequently used spin-off media to explore side stories and character studies that do not fit within the main narrative’s linear progression. By dedicating a project to the heroines, the production targets a specific segment of the audience and creates a new entry point for viewers interested in the supporting cast.

Crunchyroll has not yet specified the full release date for the series or the availability of the theme song on streaming platforms, though the trailer serves as the primary announcement for the project’s current development stage.
