"Please tell me about yourself. Maybe then I'll know how to sing."
Hoshino Ichika unexpectedly hears a song sung by Hatsune Miku at a record store, a song she had never heard before. As she wonders about it, she notices a screen showing an unfamiliar "Hatsune Miku." Shocked, she exclaims, "Miku!?" Startled by Ichika's shout, Miku makes eye contact with her but quickly disappears.

After a street performance a few days later, the same Miku suddenly appears on Ichika's phone. Looking somewhat despondent, Miku shares her story with Ichika, revealing her wish to convey her songs to certain people. However, no matter how much she sings, her voice never seems to reach them.

During the recent concert, Miku saw Ichika touching many hearts with her voice. It gave Miku hope that by understanding Ichika, she might also be able to transmit her voice to others. Summoning her courage, she approaches Ichika. Ichika smiles in response to her request and says, "If I can help in any way," readily agreeing to assist her. Thus begins the new story of Hatsune Miku and the teenagers.
