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.
It'd be pointless training 
if I didn't take the risk.

Si no me arriesgo,
no vale la pena entrenar.

se eu não corresse o risco.
Без подобного риска
тренировки лишены смысла.
ถ้าไม่ทำถึงขนาดนั้น
ฝึกไปก็ไม่มีประโยชน์
