Ever since he was a young boy, Ren Nanahoshi had an intense desire to experience the exhilaration of attending a live festival. Now, as a first-year university student, he spends most of his days in solitude, perfecting his singing skills in the hopes of reliving that same rush of adrenaline. One fateful night at a local karaoke bar, he meets two aspiring musicians, Yuuto Goryou and Wataru Matoba, who are completely mesmerized by his singing. Determined to complete their band, they ask Nanahoshi to be their lead vocalist. Initially hesitant to join their group, Nanahoshi eventually agrees after witnessing the raw energy of their live performances. Teaming up with Rio Kikyou's nonchalant charisma and Banri Shiroishi's deep-seated passion, the five musicians form a band called "Argonavis" and set their sights on headlining at the prestigious Destiny Rock Festival. But as they strive towards success, they soon realize that the path to fame is fraught with obstacles.
