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.
It really was a mistake to 
summon all four together.
كان من الخطأ استدعاء كلّ الأربعة معاً
Es war tatsächlich ein Fehler,
gleich alle vier zu beschwören.
Fue un error invocarlos
a los cuatro a la vez.
Fue un error invocarlos
a los cuatro a la vez.
On n’aurait pas dû invoquer
les quatre héros ensemble.
A quanto pare evocarli tutti e quattro insieme 
è stato un errore.
Foi um erro ter invocado
vocês quatro juntos.
Всё-таки…
не стоило всех героев разом призывать.
