Akane Saijo: The Drummer on a Path to Redemption

Her authentic talent and determination draw the attention of Naoki Fujitani, a reclusive yet brilliant musician who sees her potential. Akane’s story mirrors the struggles many young artists face while chasing their dreams.
Yu Miyazaki delivers a genuine and engaging performance, capturing both the vulnerability and resilience of a young musician eager to prove herself. Her development throughout the series showcases how a passion for music can help overcome significant challenges.
