Thirty-five years have elapsed since Lynn Minmay secured peace between the Zentradi and humanity during the events of Macross. Nekki Basara serves as the guitarist and vocalist for the band Fire Bomber. Residing in a less-developed section of the flying colony City 7, which is searching for a habitable planet, he writes and performs songs based on the conviction that music possesses superior power. While in flight, an unidentified alien race emerged and began besieging City 7. Their assaults, however, are unconventional; rather than attempting to destroy the colony, they steal "spiritia," leaving victims unresponsive and zombie-like. Amidst these conflicts, Basara consistently ventures into the heart of the warzone, singing his songs with the expectation that both allies and enemies will listen and be moved by his music.
