Being Iwatani Naofumi is hard, full of suffering and thankless job. Not only he was kidnapped from his home world without a warning, he was shoved headfirst into crapsaccharine world as The Shield Hero... in a country that hates him! Nevermind that he was the only sane man among the so-called Four Heroes. This is going to make his blood pressure shot through the roof... (A what if fic where Naofumi is not complete Tank and slightly more prepared)
