Chou Kaguya-hime!

Seventeen-year-old Iroha Sakayori barely has room to breathe between school and part-time work. Her escape is Tsukuyomi, a virtual world where people can create freely and live as someone new. There she follows her favorite streamer, Yachiyo, and quietly writes music of her own. One evening, Iroha discovers an iridescent telephone pole from which a baby mysteriously emerges, then rapidly grows into a girl her own age.

The girl calls herself Kaguya and quickly decides she wants to sing in Tsukuyomi. Iroha becomes her songwriter and producer, and their partnership deepens as Kaguya's voice reaches more people. Yet the brighter she shines, the closer mysterious forces draw, intent on returning Kaguya to the moon and ending the future the two girls have only just begun to imagine.
