Dungeon Meshi (Anime) Wiki

When young adventurer Laios and his company are attacked and soundly thrashed by a dragon deep in a dungeon, the party loses all its money and provisions…and a member! They’re eager to return and save her, but there is one problem: If they set out with no food or coin to speak of, they’re sure to starve on the way! But Laios comes up with a brilliant idea: “Let’s eat the monsters!” Slimes, basilisks, and even dragons—none are safe from the appetites of these dungeon-crawling gourmands!
