In the year A.D. 2040, thirty years after the battle between Earth and the Zentraedi reshaped both societies, a clandestine program called “Supernova” is underway on planet Eden to select the next‑generation variable fighter for U.N. Spacy. The competition pits Shinsei Industries’ YF‑19 against General Galaxy’s YF‑21. Guld Goa Bowman, a half‑human, half‑Zentraedi pilot, commands the YF‑21, while the unruly fighter pilot Isamu Dyson, once a friend of Guld, takes the helm of the YF‑19. As the two pilots engage in fierce duels to prove their aircraft’s superiority, the virtuo‑roid idol Sharon Apple prepares to launch her debut concert on Eden, with her production team overseeing the event.
