This story is a sequel to Sour's on the case!
If there is one thing Lemon Zest loves, it's music! So it only makes sense that one day, she decides to start a band out of the blue. However, her fellow Shadowbolts and best friends don't seem interested in playing music with her, claiming their genre preferences are too different for this to work. When everyone else at Crystal Prep Academy turns her down as well and she is about to give up, she unexpectedly receives help from two girls outside of her school. But soon, Lemon must learn creative differences as well as a certain past between her fellow band members might make this band thing a bit more complicated han she originally thought it would be...
