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 left your body wide open,
 you beefy dumbass!
تركت جسدك عِرضة للهجمات أيّها
!الأحمق مفتول العضلات
Mit Verteidigung haste’s wohl nicht so,
du retardiertes Rindvieh!
¡Dejaste el estómago al descubierto,
toro estúpido!
¡Dejaste el estómago al descubierto,
toro estúpido!
T’as le bide à découvert,
taureau de mes deux !
Sei completamente scoperto, brutto idiota!
Você deixou sua barriga
cheia de brechas, seu burro!
А живот оставил без защиты, тупой бычара!
