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.
Will you throw me in jail 
until the Waves arrive?
هل ستزجّني في السّجن إلى حين 
وصول الموجات؟
¿Encerrarme hasta que vengan las Olas?
¿Encerrarme hasta que vengan las Olas?
M’enfermer au cachot
en attendant les vagues ?
Mi chiuderete in cella
fino all'arrivo della prossima Ondata?
Vai me enfiar numa prisão
até as ondas virem?
Бросите в клетку
до прихода Волны?
