Demons lurking for prey in dreams.
The most commonly known beings to humans were succubi and incubi.
Although they sucked human vitality through dreams, throughout history, the human population was never always abundant.
There were even worst-case scenarios, like when the number of humans drastically decreased due to plagues and frequent wars.
During those times, they, like other monsters, engaged in cannibalism among their own kind.
Succubi took incubi, or vice-versa.
And now that everything has stabilized, those who would seek cannibalism have disappeared.
There was simply no reason to forcefully take from each other when they could just deal with weaker humans.
“I’m looking forward to it.”
However, there was one who intended to enact cannibalism, something not performed for a long time.
It was ‘Lucaros’, an incubus.
Lucaros was the owner of an Incubus Dungeon.
It wasn’t a large dungeon, but it wasn’t small either.
He owned a dungeon of just the right size, with a moderate force established.
And a little while ago, Lucaros had received a message from a representative of the Underworld Merchant Guild.
The request was to simply eliminate a succubus.
Lucaros accepted without much thought.
The person in charge of him, Jewel, held a certain position within the guild.
Considering future transactions, it wasn’t a bad idea to incur a debt now by offering help.
This debt would later provide an advantageous position in goods transactions with the guild.
If so, he could accelerate the dungeon’s development more smoothly.
Most importantly, if the dungeon developed, his own power as its owner would also increase.
In a structure where the owner’s power rising also elevated his subordinates, no one would refuse dungeon development.
And for dungeon development, the Underworld Merchant Guild was essential.
Ultimately, it was a story that continued in a cycle.
Therefore, Lucaros readily accepted Jewel’s request and had set out.
It wasn’t solely about incurring a debt.
Lucaros had been bored lately and was in need of a little change.
“It’s been so long since I dealt with a succubus?”
Lucaros’s expression was cold yet arrogant.
According to Jewel, the succubus was the owner of a small, newly established dungeon.
That meant he could easily overpower the succubus and take her vitality.
“Is this the place?”
Lucaros soon entered the mountain range.
Even though he was disguised as a human, he was fundamentally a monster, so physical strength was not a concern.
Rather, eager to claim his target quickly, he was sprinting towards the location Jewel had informed him of.
“……”
Then, a sudden gust of wind stopped Lucaros in his tracks.
The pleasant breeze made the flowers and leaves dance vibrantly.
The chirping of birds pleased his ears and lifted his spirits.
It even felt as if it was instilling passion and energy into him.
“Haa… Should I try to have a dungeon in a place like this?”
If necessary, forcibly taking the succubus’s dungeon was also an option.
That thought occurred to him because this place was truly beautiful and enchanting.
As Lucaros was lost in thought for a moment.
“Oh my, are you perhaps an adventurer?”
Someone spoke to him.
Lucaros turned his head and looked at the speaker.
‘An adventurer?’
Her attire suggested she was an adventurer.
And most importantly, she was a woman.
Moreover, she possessed a very beautiful appearance.
‘She seems to be of a low rank.’
Despite her appearance, she seemed to be an adventurer without much ability.
Judging by the fact that she didn’t recognize him disguised as a human, she must be rather insignificant.
However, Lucaros was an incubus.
He wouldn’t casually let go of such fresh prey that had walked right into his path.
He smiled and spoke to the adventurer.
“Haha, I was just on my way to subjugate a nearby dungeon. Would you care to accompany me if you don’t mind?”
Lucaros’s words were laced with a suggestive tone.
It was a conversation that felt comfortable yet forced, and at the same time, evoked an indescribable feeling.
“Yes, I’d love to!”
The adventurer accepted with a smile.
‘Good.’
He would use this woman at his side as a finisher after dealing with the succubus.
Lucaros followed the adventurer, who was already as good as his, with a sinister smile.
Eventually, he arrived near his target dungeon.
“Is this it?”
The cave was hidden among the trees.
From the outside, it looked quite unimpressive.
He wondered if calling this a dungeon was even appropriate.
‘It’s too small?’
It seemed like it would fall easily, even without him.
Perhaps it would be better for the succubus if that happened.
If she were captured by him, at best, her vitality would be drained and she would be disgraced, but being captured by humans would lead to worse.
If she were lucky, she might die cleanly.
“Lucky girl.”
Lucaros thus considered himself a savior.
“Is this the place?”
The female adventurer spoke to him.
Come to think of it, he didn’t even know her name, but it didn’t matter.
After taking care of the succubus, the next target would be this woman.
It was merely a fleeting pleasure, not even for a night, and he had no further feelings, so he didn’t feel the need to know her name.
“Come, let’s go inside.”
At Lucaros’s words, the female adventurer took the lead and walked into the dungeon.
Even though it was a small dungeon, it was foolish to enter first, so Lucaros slowly followed her.
“Hmm.”
Contrary to its exterior, the interior was clean, as if well-maintained.
What surprised him most was that the dungeon was much larger than expected.
‘Is this dungeon really that new?’
Jewel had explicitly said so.
That it was a newly established place.
But this was far too large.
What’s more, after walking a bit further, there were even three branching paths.
At this point, it was definitely not small.
A sense of unease began to creep into Lucaros’s mind.
‘After all, my opponent is a succubus.’
Regardless of the dungeon’s size, the owner was a succubus.
She wouldn’t have the power to do anything to him, at least.
Or so he believed.
Lucaros changed his strategy.
It was a waste to have come this far, but he decided to abandon Jewel’s request.
However, he needed some reward for coming all this way.
Lucaros decided to claim the adventurer walking in front of him.
Perhaps the dungeon’s owner would also wish for that.
If he quietly took a human and left, they certainly wouldn’t interfere.
The adventurer in front of him continued walking and suddenly stopped.
“Lord Lucaros. Shall we do it here?”
The other party preemptively made the request.
Like Lucaros, her words were imbued with a suggestive desire.
“Haa….”
Lucaros’s lips curled up.
It happened sometimes.
When a woman with an incubus would become aroused and initiate.
‘But did I tell her my name?’
He didn’t remember.
But he was thinking of quickly taking the human in front of him and leaving the dungeon, so he decided not to dwell on it.
Lucaros grabbed the adventurer’s hand.
The feel of the adventurer’s hand transmitted to Lucaros.
It was warm.
And rough.
“Rough…?”
Yes, this was not a soft sensation.
It felt as if he were touching skin covered in fur.
Lucaros tilted his head slightly to the side.
Certainly, female humans had hair, but the sensation he felt was on a completely different level.
Lucaros withdrew his hand and brought his own hand to the entity in front of him.
“Strange?”
It wasn’t smooth or soft.
It truly felt like it was covered in fur.
“How is it?”
Lucaros’s puzzled ears still heard the lingering, suggestive voice of the female adventurer.
“Do you like it? This is a monster brought from a dungeon directly subjugated by Sir Death Knight.”
Monster? Death Knight?
What was this talk about?
The way the adventurer spoke changed.
And most importantly.
The adventurer’s voice was no longer coming from in front of him but from behind.
“Uh…?”
Strange. She was definitely in front of him.
Then, what was standing before him now?
Lucaros squeezed his eyes shut and slowly opened them.
The one he had been so eagerly fondling was not the female adventurer.
“…A spider?”
It was a giant spider.
Transparent liquid dripped from the spider’s mouth onto his hand.
“Eek!”
He tried to pull his hand away in terror, but his body wouldn’t obey.
“Who dares to covet the Master’s dungeon?”
The adventurer, or rather, the former adventurer.
No, the being who was not an adventurer in the first place.
Lucaros’s mind went blank.
He was rambling, unsure of what he was thinking or saying.
But one thing was certain.
He was the one caught in the trap.
And his opponent was not a mere succubus.
“Please….”
Lucaros pleaded.
“I was foolish. Please spare my life. Your Majesty!”
Judging by her presence alone, she far surpassed a Succubus Queen.
Therefore, Lucaros wailed and pleaded even more.
He begged for his insignificant life.
At the same time, he cursed Jewel, who had brought him here.
“What can you do if I spare your life?”
A sweet proposal emerged.
Lucaros immediately opened his mouth.
“I’ll tell you the mastermind behind this incident! The culprit!”
Lucaros headbutted the ground as he begged.
“If you spare me, I’ll never leave the Incubus Dungeon again! Please!”
It was impossible to never leave the dungeon, but what couldn’t he say in his current situation?
He was that desperate.
“Incubus Dungeon, you say… Well, alright. I accept your offer. However, I must seek permission from the Master.”
Hope dawned on Lucaros’s face.
He was momentarily puzzled by the mention of another Master, but it didn’t matter.
He had hope of surviving.
He had hope of keeping his life.

Ding-
His smartphone alarm rang.
“Phone.”
The skeleton soldier, who was cleaning, quickly brought the smartphone to me.
“What alarm is it this time?”
– Lieutenant Celia has made a request to Master.
A request?
If Celia was requesting something, I intended to grant it.
“Let’s see what the request is.”
I checked the request sent by Celia.
The gist was: how to deal with a lost incubus.
“Ah!”
That wouldn’t be difficult.
A truly unfortunate incubus who had lost his way.
“Come to think of it, didn’t I have some followers?”
I immediately checked the dungeon support list.
There was one Incubus Dungeon that had pledged loyalty to me after Celia was dispatched last time.
I could confirm that the beings from that place still existed.
Since they had pledged their loyalty to me, I could provide support to that dungeon anytime.
“It would be good to make friends with many people, wouldn’t it?”
I dispatched Celia to the Incubus Dungeon and ordered her to guide the lost incubus.
* * *
“Ah, Master even pays attention to details like this….”
In an Incubus Dungeon located on Earth.
Azmo, the owner of that dungeon, looked at Lucaros, whom Celia had brought, with admiration.
The beings here were always hungry.
They couldn’t afford to be picky about food.
“Master is always merciful, Azmo.”
Celia smiled and handed Lucaros over to Azmo.
Thus, Lucaros was able to keep his word.
The promise not to leave the Incubus Dungeon.
The night that will arrive today is deep, and tomorrow will bring its own night.
