Become a dungeon master and fight off adventurers!
You are the dungeon master of the Demon King's army, in charge of the dungeon closest to the human town called "Town of Beginnings."

This dungeon is a popular dungeon where novice adventurers come to test their skills, but due to the location, strong adventurers don't visit, so I spend my ordinary days dealing with novice adventurers as I see fit. . However, the other day, a terrible fact came to light.

In fact, it was discovered that the legendary holy sword used by the previous hero was hidden among the treasures placed at the back of the dungeon.

According to research, this holy sword has the ability to cut through mountains with a single swing.

An average monster cannot even touch it due to the overwhelming power of the holy sword. If the Holy Sword were to be found by an adventurer, especially a hero, it would be obvious that the Demon King's army would be at a disadvantage.

Will you be able to fight off the adventurers who challenge you one after another and protect the legendary holy sword that lies deep in the dungeon?
