The story follows Ichika Hoshino, who hears a Miku song that she has never heard before at a CD shop and sees a Hatsune Miku whom she had never seen before. Ichika calls out to Miku, who surprised by the voice, disappears shortly after making eye contact. Miku later appears on Ichika's smartphone to tell her that she would like to reach others with her songs, but no matter how much she sings, her songs cannot reach them. After seeing Ichika reach others' hearts with her live street performance, Miku asks for her help.
