If one follows Shoji Kawamori’s somewhat dodgy, albeit interesting, excuse for an overall Macross timeline, his answer is this: much like history that is studied in classrooms and recreated in period dramas, Macross is the retelling of a historical event. The characters themselves may change, but every iteration will have the Macross staples of fighter pilots in transforming Valkyrie robots, idol singers, and a love triangle.
The first episode of Macross Delta breezes through this checklist with obvious ease. Plucky stowaway Freyja Wion, disillusioned grunt worker Hayate Immelman, and hapless Delta Platoon Lieutenant Mirage Farina Jenius – whose last name should immediately ring a bell with the seasoned Macross fan. Presumably, these three will compose the expected love triangle that will develop against the backdrop of a virus that is both spawned from song and quelled by song. Other checkmarks include the alien race Zentradi, a fighter pilot squadron, and an established group of idol singers that said squadron protects: Walkure.
