It is the year 2040, and the galaxy is thriving with numerous colonies and advanced technology. Artificial intelligence has reached near-perfection, and the current top idol is the nearly complete Virturoid, Sharon Apple. The only thing lacking is her genuine emotions, which are instead provided by Myung Fang Lone. Sharon's debut concert takes place on the planet Eden, where fighter pilots Isamu Dyson and Guld Bowman are simultaneously battling for air superiority in the "Supernova Project." Isamu, Guld, and Myung were once childhood friends, but following an accident seven years prior, they parted ways. With Myung returning to the scene, old conflicts are reignited. Furthermore, the situation deteriorates when an unstable and illegal AI technique is installed in Sharon.
