Yukikaze - S01

It has been 33 years since an alien race called the JAM came through a hyperspace passage over Antarctica with one goal: to invade Earth. Their first attacks caught everyone off guard, but humanity fought back together, pushing the JAM off Earth and eventually moving the frontlines to the JAM's homeworld, Fairy. Most people on Earth have long since stopped thinking about it, but the war continues on Fairy, where the United Nations has set up five bases and a powerful, technologically advanced military, including the Fairy Air Force (FAF). Lieutenant Rei Fukai is a pilot in the FAF Special Air Force's Boomerang reconnaissance squadron, flying a Super Sylph fighter jet he calls "Yukikaze." He flies high above the fighting, watching battles for air superiority and gathering and analyzing intelligence on JAM tactics. His piloting skills are unmatched, but he also depends heavily on his aircraft's advanced weapons and nearly sentient AI system. Other FAF members dislike him for being antisocial and distant, but Lt. Fukai keeps doing his job alongside Yukikaze. Then, during a particularly bloody battle, an unresponsive and hostile aircraft appears and catches him off guard, an aircraft that is the same make and model as his own.
