Dungeon ni Deai wo Motomeru no wa Machigatteiru Darou ka III

Bell Cranel finds a vouivre in the Dungeon that looks like a frightened young girl. Instead of attacking him, she cries, speaks, and flees from adventurers hunting her. Bell names her Wiene, and Hestia Familia chooses to hide and protect her, even though the existence of an intelligent monster challenges everything Orario has believed about the creatures it has fought for generations.

Bell soon learns that Wiene is not alone. Deep within the Dungeon exists a group of speaking monsters who want to live rather than prey on humans. Protecting them puts Bell against hunters, adventurers, and even people who once admired him as a hero. For the first time, strength is not the hardest question he faces; he must decide whether compassion remains right when the entire city refuses to recognize the humanity of those he is trying to save.
