College student Iwatani Naofumi is reading a book titled "The Records of the Four Cardinal Weapons" in the library when he is suddenly summoned to another world and told he has to save the world as the Shield Hero, one of the Four Cardinal Heroes. And one morning, he finds all his money and equipment gone.
And if you send us home as soon as peace 
is restored, we'd have worked for nothing.
وإذا رميتمونا في الخارج حالما يعمُّ السّلام
من جديد فسنكون كأنّنا عمِلنا بلا مُقابِل
Und wir wollen auch nicht nach getaner Arbeit
ohne Lohn heimgeschickt werden.
No pensamos trabajar gratis
solo para volver a casa.
No pensamos trabajar gratis
solo para volver a casa.
On aura bossé pour rien
si vous nous jetez une fois en paix.
Inoltre, se ci farete tornare nel nostro mondo
non appena ristabilita la pace,
E se nos mandarem de volta ao nosso mundo
assim que a paz voltar, isso terá sido de graça.
К тому же не очень-то хочется
добиться мира, а потом улететь без оплаты.
