Ren Nanahoshi has been pursuing a specific thrill he once felt at a live festival during his childhood. Now a first-year university student, he shuns making friends and practices singing alone, hoping to recapture that adrenaline rush. A chance meeting at a karaoke bar introduces Nanahoshi to Yuuto Goryou and Wataru Matoba, both of whom are struck by his voice. The pair has been looking for band members and wants Nanahoshi to serve as their vocalist. Nanahoshi at first turns down their persistent urging but gives in after attending their live performance and singing with them. With the addition of the easygoing Rio Kikyou and the fervent Banri Shiroishi, the five boys form "Argonavis" and aim to headline the Destiny Rock Festival. As they start working together as a band, they face the challenges and hardships inherent in chasing fame.
