Studio KAI has animated "Seikan Sekai," a new music video celebrating the 6th anniversary of The IDOLM@STER Cinderella Girls: Starlight Stage mobile game. The short, which blends idol themes with a sci-fi premise, is available to stream on YouTube with English dub and subtitles.

This is not a traditional anime series but a standalone music video, offering a glimpse into a more futuristic take on the popular idol franchise. Fans of The IDOLM@STER series, particularly Cinderella Girls, will recognize the established characters and music focus, now presented with a distinct visual flair by Studio KAI, known for their work on Mushoku Tensei: Jobless Reincarnation and Uma Musume Pretty Derby.
