The alien JAM have been at war with mankind for over thirty years... or have they? Rei Fukai of the FAF's Special Air Force and his intelligent plane, Yukikaze, have seen endless skirmishes, but after declaring "Humans are unnecissary now" and forcibly ejecting Fukai, Yukikaze is off on her own. Is the target of JAM's hostility really Earth's machines? And have the artificial intelligences of Earth been acting in concert with JAM to manipulate Yukikaze? As Fukai tries to figure out the truth behind the intentions of both sides, he realizes his own humanity might be what's at risk, and that the JAM are about to make themselves known to the world at large....
