Decades after Lynn Minmay brokered peace between humans and Zentradi in Macross, Nekki Basara, a musician in the band Fire Bomber, resides in the less affluent region of the airborne City 7. As the colony searches for a new home, Basara fervently believes in the transcendent power of music, composing and performing to spread his message. When a new alien threat emerges, targeting City 7 for its 'spiritia', a life force, instead of outright destruction, Basara defiantly takes to the battlefield with his music, aiming to touch the hearts of friend and foe alike amid the chaos of unconventional attacks.
