Blade & Bastard Novel Volume 3 was written by Kumo Kagyu with illustrations by So-bin.

Within the dungeon, a famous weapon is nothing more than a basic blade. Even a broadsword that's gutted a dragon can be reduced to shattered steel. Devastated, Garbage seeks out a replacement for her beloved sword…but what weapon could possibly match her? An old blade, sharp as diamond—the return of a legend. As ever, the dungeon's maw yawns wide to swallow foolhardy adventurers, and Iarumas's party continues to delve for treasure, for corpses, and for answers. One day, a member of Raraja's former clan catches up to him and dangles a tantalizing proposition: in exchange for clues about the rhea girl's whereabouts, Raraja must go into the dungeon alone. What could await him but a dark, lonely death? What awaits Garbage but a jagged, broken sword? And what slumbering legends might awaken in the blackest depths of the dungeon?
