Blade & Bastard, Vol. 5 (light novel)

Who rules over the dungeon? The adventurers who plunder its riches...or the fathomless foes that lurk in the gloom? When Crown Prince Festin visits Scale, he seeks to bring the adventurers to heel and assert the kingdom’s power over the dungeon. He soon meets Garbage, and though their statuses are polar opposites, the two bear a striking and uncanny physical resemblance. And then, the crown prince vanishes into the maw of the dungeon.

Signs point to him being kidnapped and dragged to the depths. Sezmar’s, Schumacher’s, and Iarumas’s parties are sent in to rescue the prince, but when the adventurers descend, they are greeted with the mocking laughter of a bizarre and powerful enemy. Who rules over that unknowable abyss? Perhaps the truth can only be found within the dungeon.
