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.
To think the Shield Hero would commit 
the gravest sin in this country.
لا أصدِّق أن يرتكب بطلُ التّرس
أكبر خطيئة في هذا البلد
Dass der Held des Schilds das schlimmste
Verbrechen in unserem Lande begehen würde …
Cometiste el peor tabú
de nuestro reino, héroe del escudo.
Cometiste el peor tabú
de nuestro reino, héroe del escudo.
Le héros au bouclier a commis
le plus grand péché de ce royaume.
Che a commettere il crimine più spregevole che esista
in questo regno sia stato proprio l'Eroe con Scudo...
E pensar que você, Herói de Escudo, iria
cometer o maior dos pecados de nosso país.
Подумать только, что Герой Щита
совершит самый тяжкий из грехов…
