The series narrates the tale of a university drummer who faces an unjust expulsion from her band but gets a second chance when a brilliant musician discovers her talent.

Akane Saijo (Yu Miyazaki) is a university student with a passion for drumming who encounters a heartbreaking injustice when she is expelled from her band just before their debut. Her true talent and relentless spirit attract the attention of Naoki Fujitani, a gifted yet reclusive musician who sees her potential. Akane’s journey symbolizes the challenges faced by many young artists striving to achieve their dreams.
Yu Miyazaki delivers a compelling and genuine performance, embodying both the fragility and determination of a young artist eager to validate her abilities. Her character’s growth throughout the series illustrates how a passion for music can help one surmount even the toughest challenges.
