Special-rank angels carry them because 
they're Arrows of Peaceful Death.
تحمله الملائكة ذوي الرتبة الخاصّة
لأنّها أسهم موتٍ مسالم
Engel der Sonderklasse haben sie, weil sie
als Pfeile des Friedlichen Todes gelten
Para evitarle el sufrimiento
a aquellos que van a morir pronto.
Para evitarle el sufrimiento
a aquellos que van a morir pronto.
Elle plonge dans un sommeil paisible
ceux dont le dernier jour est venu.
Gli angeli di livello speciale le hanno perché
sono le Frecce della Morte Serena.
Porque é uma “Flecha da Eutanásia”,
Чтобы умирающий не страдал,
а спокойно заснул вечным сном.
