Centuries ago, vicious and bloodthirsty demons who were immune to all manner of weaponry plagued mankind. Humanity's cries for help brought forth the Idaten; battle deities who would use their incredible speed to hunt the demons down, and then seal them away. In the following 800 years of peace, the Idaten have not had any enemies to fight. But that is about to change...
You drag me out here every day, 
work me to the bone... And for what?
تجرّينني إلى هنا كلّ يوم وتُجهدينني في العمل... ولماذا؟
Du schleifst mich täglich hier raus
und triezt mich. Wofür?
À quoi ça sert de me torturer
tous les jours ?
Mi trascini qui ogni giorno e
mi fai lavorare sodo, ma a quale scopo?
Você me arrasta pra cá todos
os dias... Qual o sentido?
Каждый день гоняешь меня до смерти...
А какой в этом смысл?
