There is one place that has withstood attempts by every army to conquer it—the city-sized labyrinth known as the Deepest, Most Unknowable Dungeon. But now, after dying on Earth as a young temp worker, Jean is reborn into the world with a fascination for its most infamous dungeon. With the right training and the most carefully chosen set of lustful comrades-in-arms, he may have the chance to accomplish the impossible and become a legend in a new fantasy world!

The Deepest, Most Unknowable Dungeon is full of secrets--and dangers. Kukoro, Mexy, and Ceres come to terms with captivity as Jean continues to hone the skills of his all-female party. Meanwhile, Cross learns more about the mysterious Holy Saint Slaughterer.

NAKED AND…PREPARED! Surviving the Deepest, Most Unknowable Dungeon takes more than fighting skills. Jean and his all-female party are brought into the woods, stripped of everything, and start training the skills they’ll need to live through the night. But will Jean be able to secure food, water, and clothing for him and the girls…or will he succumb to the temptations of other nighttime activities?

SHOOT TO KILL! The Deepest, Most Unknowable Dungeon is the deadliest stretch of ground in the new world into which Jean has been reincarnated. Even the top-ranked Holy Saint Slaughterer, the Queen of Darkness, and the Bow King are unable to defeat the demihuman hordes, or conquer the dungeon. But using Earth knowledge from his former life, Jean may just be able to develop the ultimate weapon—an arrow that can pierce any armor—and change the game forever!
