The Xi: unidentified flying objects that are vastly more powerful than humanity's best fighters. Kei Narutani is fleeing Shanghai on an evacuation ship when he's attacked by the Xi, but a mysterious red fighter jet saves him. One day in his new home in Komatsu, he sees the same jet. It's being carried to a nearby Japanese air-force base.
Nobody's ever been able 
to shoot down the Xi,
،لم يستطع أحد إسقاط الزّاي من قبل
Der hat die bisher unbesiegbaren
Maschinen von Zai vom Himmel geholt.
Nadie había derribado a un Xi,
pero ese los hizo pedazos.
Nadie había derribado a un Xi,
pero ese los hizo pedazos.
Il a abattu les Zai,
contre qui personne n’a fait jeu égal.
Nessuno è mai stato in grado di abbattere gli Xi,
Ninguém nunca havia derrubado um Zai,
Он в два счёта уделал Дзай,
которых никто не мог победить!
