Music idol Sheryl Nome arrives at the Macross Frontier fleet for a concert performance. In the meantime, fleet command deals with an unidentified & powerful alien enemy.

Overwhelmed by the new enemies' speed & power (despite their lesser numbers), fleet defenses cannot prevent some of the alien bio mecha from penetrating the main colony ship. Teenage music fan Ranka Lee, young student Saotome Alto & S.M.S. VF-25 veteran pilot Ozma Lee are all involved in the ordeal.

Alto Saotome unexpectedly meets Ranka Lee and Sheryl Nome again at an observation park. However, the Vajra also shows up in the skies above the three, so they immediately head to the park's emergency shelter and get trapped inside.

Sheryl gives a consolation concert at planet Galia 4, but because of an undisclosed illness she cancels her concert, which causes a huge riot.
