Hikaru Hoshina and Lala Hagoromo find a tiny star-shaped creature in Lala's gummy case after a meteor shower, name it Yuma, and learn that it answers them through song instead of words. Lala and Yuma bond over music and a shared urge to explore, but alien hunters soon land on Earth with a bounty on the little creature. The Star☆Twinkle Precure team, Madoka Kaguya and Elena Amamiya included, sets out to protect Yuma in this theatrical film spun off from the Star☆Twinkle Precure TV series.
