Since she was very young, Kasumi Toyama has always been searching for the “Star Beat”, a sparkling and exciting sound she heard while looking up at the night sky. Just after getting into high school, Kasumi comes across a “star-shaped guitar” in the storage area of an old pawn shop. Feeling a rush and excitement she has never felt before, Kasumi teams up with four other girls and embarks on a journey to seek out the shiny place. We promise to perform a live here!
