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.
the closer you got to them, 
the harder they'd be to see.
فستصبح من الصّعب رؤيتها 
.كلّما اقتربنا إليها
entre más lo hagan,
serán más difíciles de ver.
a más se acerquen,
más difícil será darles.
plus on se rapproche,
plus l’ennemi devient flou.
più la distanza diminuisce,
più sarebbe difficile vederli.
quando mais próximo estiver deles,
mais difícil é para enxergá-los.
