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.
How am I supposed to fight 
with just a shield?
كيف لي أن أقاتل بمُجرّد ترس؟
Ich muss wirklich nur
mit dem Schild kämpfen?!
¿Tengo que pelear solo con el escudo?
¿Tengo que pelear solo con el escudo?
Je dois me battre
avec le bouclier ?
Come posso combattere solo con uno scudo?
E como eu devo lutar usando um escudo?
Как же одним щитом сражаться?
