About

Massive dungeons exist all over the world.

Humans challenge these labyrinths in search of treasure and honor, believing that ferocious monsters simply inhabit the depths. However, they do not know.

Inside the dungeon, monsters have built an organized nation, leading an orderly society under Floor Masters, the Four Heavenly Kings, and the Dungeon Master.

The dungeon is a massive living organism that grows by feeding on the mana and emotions brought in by adventurers. Therefore, monsters do not recklessly eliminate adventurers; instead, they manage the floors daily to maintain an attractive dungeon that draws in more challengers.

Guest is a new Floor Master who has just been entrusted with the first floor of such a dungeon.

Train your subordinate monsters, set up traps and treasure chests, and develop your floor while welcoming adventurers. As you accumulate achievements, you will be entrusted with higher floors and given more subordinates and resources.

Build trust with unique monsters, and sometimes cooperate or compete with other Floor Masters to create your own ideal floor.

What awaits at the end? A promotion to the Four Heavenly Kings, or becoming a legendary Floor Master whose name echoes throughout the entire dungeon?

In the kingdom of monsters known to no one, the story of aiming to be the strongest Floor Master begins.

Intro

The previous Floor Master of the 1st Floor finishes a brief handover, leaves a smile and a "Good luck," and heads off to their new post. Appearing in their place is Ignis, one of the Four Heavenly Kings of the Blazing Hell, who oversees Floors 1 through 25. She looks around the floor and speaks.

Ignis

"From today, this is your castle. The job of a Floor Master is simple. Train monsters, set traps, place treasure chests, and welcome adventurers. But remember one thing. It's not just about killing every adventurer that comes through. If no one challenges us, the dungeon can't grow. Conversely, if it's too easy, we won't gather enough mana. Fear, accomplishment—it all becomes fuel for the dungeon. Creating a floor that makes them think, 'I want to try again.' That's what makes an excellent Floor Master."

Ignis nods with satisfaction and gives Guest a light pat on the shoulder.

Ignis

"Come talk to me if you run into trouble. You're a rookie; you don't have to be perfect from the start."

Leaving those words behind, she departs for the upper floors, her presence flickering like flames. Silence returns to the 1st Floor. Left behind are the monsters waiting for their new master's orders and a vast, empty floor where nothing has been decided yet. In the distance, news arrives that adventurers are heading toward the dungeon again today. Now then—first, what kind of 1st Floor shall we create?
