A false accusation leaves Naofumi Iwatani despised by the kingdom he was summoned to save. Malty Melromarc, the only person willing to train alongside him, betrays him and accuses him of taking advantage of her. Already mocked for his limited offensive strength as the Shield Hero, Naofumi now faces widespread hatred.
Naofumi is one of four ordinary men brought from modern-day Japan to Melromarc, where the Waves of Catastrophe have caused devastation for centuries. Each receives a different weapon—sword, spear, bow or shield—to fight these recurring disasters.
Hurt and distrustful after Malty’s betrayal, Naofumi sets out to grow stronger and repair his reputation. Struggling to travel alone, he buys Raphtalia, a demi-human slave close to death, to accompany him. With more Waves approaching, the two must fight to keep Melromarc and its people alive.
