Thirty-three years ago, an alien force known as the "JAM" invaded Earth through a dimensional portal over Antarctica. Earth's forces managed to drive the JAM away to a distant planet designated as "Fairy." While majority of Earth's population is unaware of the JAM's presence, the war continues on Fairy. Sentou Yousei Yukikaze chronicles the life of Rei Fukai, an SAF (Special Air Force) pilot assigned to pilot "Yukikaze" - an advanced reconnaisance fighter plane equipped with a near-sentient A.I. that detects the presence of the JAM within its path.
