Tate no Yuusha no Nariagari

Naofumi is thrust into a world that in every way resembles an heroic fantasy role-playing game. But while other heroes have been endowed with formidable offensive weapons, Naofumi inherits a shield with limited capabilities to progress in this game where danger can arise at any moment. Betrayed by his partner and reviled by the populace, the young man can now only rely on himself to survive in this hostile universe… and perhaps on an idle young girl with unsuspected resources.
