Ren Nanahoshi has been chasing the same rush he felt as a child at a live music event. Now, in his first year of university, he shuns friendships and practices singing alone, hoping to recapture that surge. A chance meeting at a karaoke lounge introduces Nanahoshi to Yuuto Goryou and Wataru Matoba—both struck by his tone. The duo has been hunting for bandmates and invites Nanahoshi to join as their lead singer.
Initially, he rejects their persistent requests but eventually gives in after watching their concert and sharing the stage. With the easygoing Rio Kikyou and devoted Banri Shiroishi, the five form "Argonavis" and aim to headline the Destiny Rock Festival. As they collaborate, they face the hardships that accompany a quest for fame. Their journey is marked by relentless practice, creative clashes, and the pressure of performing before large crowds, together with hope.
