Kana Tomizawa, Mizuki Haruko, and Fumi Miyajima, third-year students in the dance club at Asahi Girls' High School in Fukuoka, were diligently practicing for their upcoming graduation performance. They were supposed to deliver the best performance to the song "Euphoria" by RINAO, a Japanese artist who has captivated the world. However, on the day of the performance, it was discovered that the royalties for the use of the song had not been paid, and the performance was canceled. Faced with the harsh reality of the copyright system, the girls overcome many difficulties and reclaim what "true music" means to them and their freedom.
