For three decades and a year, the extraterrestrial faction dubbed JAM has been looming over Earth after surfacing through a hyperspace corridor above Antarctica, intent on conquest. Though their initial strikes were unforeseen, humanity united to repel the JAM from Earth and shift combat zones onto the alien world of Fairy. For most people on our planet, the war seems distant, yet it continues fiercely on Fairy where the United Nations maintains five forward bases and a formidable, high‑tech military force, including the Fairy Air Force (FAF).
Lt. Rei Fukai serves as a pilot in the FAF Special Air Force"s Boomerang Reconnaissance Unit, commanding a Super Sylph fighter christened "Yukikaze." From lofty altitudes he surveys aerial engagements, gathering and dissecting critical data on JAM tactics. His piloting prowess is unrivaled, yet he depends heavily on the aircraft"s cutting‑edge armaments and quasi‑sentient AI core.
Despite being shunned by his FAF peers for his aloof, solitary demeanor, Lt. Fukai persists in fulfilling his mission aboard Yukikaze. Yet during a brutal clash, an unmanned hostile jet—identical in make and model to his own—surprises the lieutenant.
