Kyo Nukui is one of those shut-ins you hear about sometimes. He never goes to school, or even leaves the house. Instead, he composes music all day, uploading it to the internet for a few views. One day out of the clear blue, he gets an email from what sounds like an older, distinguished gentleman who wants to discuss music face-to-face. Having no one to speak to about his passion, Kyo accepts the invitiation... only to find himself facing down three elementary school girls! They're fans of his music, and they want his help to hold a concert at their orphanage. The girls prove to be good musicians in their own right and have excellent equipment, but is Kyo a good enough producer?

Nukui Kyou is a high school student who tends to skip school due to a trauma in his past. Kyou secretly creates songs using vocal song synthesis software as his hobby. Three girls who just entered fifth grade - the crybaby Gotou Jun, the strong-willed Momijidani Nozomi, and the somewhat sleepy Kaneshiro Sora who takes life at her own pace - email Kyou. These three girls, who were raised together like sisters since childhood, want Kyou to help them break into music in this loli & pop symphony story.
