Angel's 3Piece!

is a Japanese light novel series written by Sagu Aoyama, with illustrations by Twinkle. The series began publication on June 10, 2012 by ASCII Media Works under their Dengeki Bunko publishing imprint.

Synopsis
Since entering high school, Kyou Nukui has not attended a single class. Instead, he spends his days locked in his bedroom composing music and posting it on the internet accompanied by his only friend's drawings, an artist with the pseudonym "Kiriyume." One day, Kyou hesitantly uploads his newest composition, and first departure from his typical style, TR03. Additionally, he does not upload under his usual handle "HibikiP," but simply under the name "me," and without a drawing from his mysterious friend.

Shortly after, Kyou receives a very polite email, not only praising his music but also somehow discerning that he is, in fact, the composer behind TR03. The e-mail also asks for a meetup in a nearby park, to which he cautiously decides to go. To his surprise, however, he finds three elementary school girls at the meeting place! Suddenly, Jun Gotou, Nozomi Momijidani, and Sora Kaneshiro ask for his help to hold a concert in their home, an old church now used as an orphanage. And though Kyou is reluctant at first, after seeing their musical abilities, he eventually decides to accept their proposal.
