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...
Did you forget the part where you beat 
the shit out of me, you senile old bitch?!
هل نسيتِ كيف أوسعتِني ضرباً أيّتها
السّاقطة العجوز الخرِفة؟
Lag vielleicht auch mit daran, dass mich so
eine senile Schreckschraube verprügelt hat!
Tu m’as tabassé en cours de route,
alors forcément, vieille gâteuse !
Ti sei dimenticata la parte in cui
mi hai pestato a sangue, vecchia decrepita?!
Que merda você tá falando, sua velha coroca?!
Você me arrebentou no meio do caminho!
Уже забыла, как отдубасила меня
на полпути, чёртова маразматичка?!
