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.
If she hadn't asked me to wait 
till dawn and call the knights,
لولا طلبها منّي أن أنتظر حتّى
،الفجر وأستدعي الفرسان
Wenn sie nicht gesagt hätte,
dass wir die Ritter morgens rufen sollen,
Si Mein no me hubiera pedido
que esperara,
Si Mein no me hubiera pedido
que esperara,
Si elle ne m’avait pas demandé
d’attendre les chevaliers,
Se lei non mi avesse chiesto di attendere
 il mattino e chiamare i cavalieri,
Se ela não tivesse dito pra esperar
amanhecer e chamar os guardas,
Если бы Майн не сказала
до утра дождаться,
