The Dungeon calls adventurers deep into its labyrinth in search of personal growth, strength, and experience. But the Dungeon is a tough master-one wrong move, one bad choice, and permanent death awaits. Lefiya, Bete, and Filvis arrive at the twenty-fourth-floor pantry looking for Aiz but instead stumble upon Hermes Familia in distress. A deadly foe has the adventurers up against the ropes and struggling to stay alive. They've uncovered the mystery of the carnivorous flower monsters but are losing hope they'll make it back to the surface to warn Orario. Can they escape the Dungeon, or will it finally have the last word?
