Dungeons suddenly emerged on Earth. Among them, the first dungeon to appear plays a role in guiding people in a changing world as a beginner (tutorial) dungeon that doesn't disappear even after being cleared.

However, this perception was nothing more than an illusion held by people.

The truth was...

It was a dungeon built by a man who, suffering from amnesia after becoming a dungeon master, couldn't find any meaning in its operation. He created it with his attendant, a doll girl, simply to survive under the worst possible conditions.

Deceiving the world, the two of them continue to operate the dungeon at their own relaxed pace even today.

This is a modern dungeon master story. It's not a story where monsters mercilessly kill people or cruelly murder them with traps.

It might be a heartwarming, craft-oriented dungeon story, complete with *boke* and *tsukkomi* humor.

The accompanying image is a bonus map of the dungeon, which appears around chapter 140.

Each chapter is approximately 2,000 to 3,000 characters long, making for a quick read. Updates are posted on Saturdays.
