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.
when you wandered 
into the demon graveyard?
عندما همتَ في مقبرة عشيرة الشّيطان؟
Als du dich in die Grabstätte

al cementerio de los demonios?
cuando entraste
en el cementerio de los demonios?
Quand tu t’étais perdu

nel cimitero dei demoni.
Quando você se perdeu no
cemitério de demônios?
когда ты забрёл в могильник демонов.
ที่ไคหลงเข้าไปในสุสานของเผ่าปีศาจน่ะ
