Delicious In Dungeon Vol. 4

Laios has a serious problem: After setting out on a quest to claim the treasure of a lost kingdom, he and his party are attacked by a Flame Dragon who eats his little sister, Farin, before they're able to teleport to safety, leaving their equipment behind. Laios finds himself penniless and his party disbanded but vows to rescue his sister before she gets digested. How's a hero supposed to do that though with no food?
The answer: living off of the creatures that live the dungeon. Slimes, scorpions, basilisks, and living armor aren't exactly delicacies, though, and some are even poisonous to the dismay of new comrades Chilchack, a "half-foot" locksmith, and Marcille, an elf magician. Before long, though, they meet up with a dwarf named Senshi who has been cooking dungeon monsters for a decade and is eager to teach Laios and his party. Can Laios learn to live off the land like a true dungeon crawler and rescue his sister before it's too late?
Vol. 4 of this comedic take on traditional RPGs by author Ryoko Kui includes chapters 22 to 28 plus an omake chapter titled "Odds and Ends About Monsters Vol. 4" and spans 192 pages.
