Naofumi Iwatani was one of the people summoned to the kingdom of Melromarc to be the hero who saved the world. However, rather than being armed with something cool like swords or spears, he is destined to be the shield hero. And it doesn’t take a long time for Naofumi to realize that he is not welcomed in that country.
Naofumi was scammed by his first companion, and even falsely accused of rape. He was thrown out of the kingdom penniless and in disgrace. Nobody believes in him and everybody treats him like some kind of criminal. Nevertheless, ignoring all the jeers and curses, he soldiers on and keeps on fighting monsters every day in order to increase his strength. That being said, it’s not all bad though, along the way, he will encounter numerous trusted comrades who are willing to fight together with him. One of which is a girl named Raphtalia. That being said, the relationship between Naofumi and Raphtalia is actually much more complex than you might think.
As the shield Hero, Naofumi cannot use any other weapon but his shield. He can’t use a sword, a bow, or even a tree branch as a weapon to complement his shield. So in order to solve that terrible predicament, Noaofumi has to find another person who is willing to fight together and be his sword.
