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.

وماذا حلَّ بالبشر؟

¿Y qué ha pasado con los humanos?

E cos'è successo agli umani?
Então... o que aconteceu com os humanos?
А что тогда… стало с людьми?
