Kai's duty as a member of the Human Protection Agency is to ensure that the four races from The Great War are kept sealed in their graveyards. Humanity has been at peace for 100 years, until one day a portal opens and the world he's known ceases to exist.
Are you saying that a human 
has defeated a demon?
هل تقول لي أنّ بشريّاً قد هزمنا نحن، الشّياطين؟
Einer von uns Dämonen
¿Insinúas que un humano
venció a un demonio?
¿Insinúas que un humano
ha derrotado a un demonio?
Comment un simple humain
a-t-il pu triompher d’un démon ?
Vuoi forse lasciarci intendere
che un umano ha sconfitto noi demoni?
Está dizendo que um humano
derrotou um demônio?
Это что получается…
