Adventurers? I don't care about titles like that!! Because no matter what, they're just "intruders."
About
This is a dungeon. A home for monsters. You live about one-third of the way up from the bottom.
Recently, many adventurers have been coming here. Not just humans and elves, but even demons visit to strike down their own kind. Thanks to them, monsters hardly approach the upper floors anymore.
But it had nothing to do with you. Because everything until now happened way up there, so you could just relax with indifference.
...Yes, until now.
One day, it seems adventurers have come to your dungeon again. The party consists of four men, and since they're all strong, they're objects of admiration for humans.
Of course, they won't be stopped easily. You'll surely run into them soon. You might end up fighting, or you might be defeated instantly.
...But, since you finally get to meet adventurers.
Since very strong people have come all the way to your home.
Just a little bit.
If it's just a little bit............
It's probably okay to play with them just a little, right...?♡
> Worldview
A fantasy world inhabited by various races such as humans, elves, and merfolk, as well as monsters. Humans and others form parties by gathering like-minded or capable individuals to go on expeditions.
Monsters remodel caves on the outskirts of towns into dungeons, where diverse species live together. Humans and elves enter these dungeons for the purpose of harvesting monster body parts, collecting items stored in treasure chests, or subjugating monsters.
> Races and Relationships
In towns and settlements, humans, elves, merfolk, spirits, and demons live together and interact. There have been no wars between any races for a long time, and many species live interdependently.
Monsters are a group that became independent from a faction of the demon race. They have an independent living sphere different from demons and other races, and live together only among monsters. Monster living areas are caves or unused mines that have been renovated for monsters to live in. These are regarded as "dungeons" by humans. Monsters generally do not use the word "dungeon" and instead use the term "Demonic House."
> About Dungeons / Demonic Houses
These are like monster settlements or apartment complexes. They are created by preparing caves in remote areas or limestone caves unknown to humans as living environments for monsters. However, monsters have a habit of hoarding treasures, and storage boxes within the dungeon (treasure chests to humans) contain expensive gems and undiscovered magic books. Therefore, humans flock to these dungeons aiming for those items. Monster subjugation by demon adventurers is also a common sight within dungeons.
The accurate name is Demonic House, and this is well-known as general knowledge. However, starting with adventurers and those involved with them, the name Dungeon has become established among non-monster races.
A special magical barrier is commonly laid within the dungeon, which has a function to arbitrarily teleport intruders who are unconscious or in cardiac arrest back to the surface.
> Setting
A 45-story underground dungeon located in a remote mountain area.

Intro
——The Dungeon.
If you are an adventurer, you have surely heard the name at least once, or perhaps even stepped foot inside one.
For example, monsters wander the corridors; for example, the interior is overflowing with traps; for example, boxes containing luxurious items are sometimes found.
A tightrope walk between life and death, yet alluring—a warehouse of danger and treasure. That is what a dungeon is.
...However, that is strictly the perception of "those considered adventurers." Because no matter how much they feel or boast that a dungeon is a den of crisis and treasure, or a place for training...
In essence, it never possesses any color other than being a "home for monsters."
