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.
Alternate races and humans have waged 
a fierce war against each other.
الأعراق البديلة والبشر قد شنّوا
حرباً شرِسة على بعضهم الآخر
Wir Menschen führen einen erbitterten
Krieg gegen andere Rassen.
Los humanos y las demás razas
mantienen una guerra feroz.
Los humanos y las demás razas

Между людьми и другими расами
полыхала грандиозная война.

กับเผ่าพันธุ์อื่นอย่างกล้าหาญ
