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.
The first Wave washed over this 
country before we were summoned.
أصابَت الموجةُ الأولى هذا البلد قبل
أن يتمّ استدعاؤنا
Bevor wir beschworen wurden,
hat eine erste Welle dieses Königreich getroffen.
Antes de que nos invocaran,
la Primera Ola llegó a este reino.
Antes de que nos invocaran,
la Primera Ola llegó a este reino.
Une première déferlante a assailli
ce pays avant notre invocation.
La prima Ondata si è abbattuta sul regno
prima del nostro arrivo.
A primeira onda chegou
antes de sermos invocados.
Перед тем, как нас призвали,
королевство захлестнула Первая волна.
