It was night.
No one came to see me after the succubus secretary had visited.
They had only delivered a meal.
Roasted meat and soup, along with a large amount of vegetables such as cauliflower.
It could hardly be called luxurious, but for a prisoner, it was an extravagant meal.
Eating it felt strangely like the last meal of a condemned prisoner.
If I succeeded in the conditioning, I would be able to eat food like this tomorrow as well.
But what if I failed?
Perhaps the raw material of the meat I was chewing would become me, and I would end up on the table of some demon—
“.......”
Fortunately, it wasn’t human flesh.
Not that I knew because I had eaten human flesh before. I knew because it had the familiar texture of pork.
...Whether it was orc meat from someone who had been killed and disposed of, or pork raised in a pigsty, I had no way of knowing. But if I didn’t want to be slaughtered and killed like this, I had to live.
Whether I had to rape someone or fuck someone, I had to succeed in the conditioning, no matter what.
I chewed the meat so that dinner would not become my last supper, scraping up even the sauce so that not a single scrap remained.
“The time has come, prospective trainer.”
The succubus secretary cleared away the meal and picked up a candlestick.
“Follow me. I’ll take you directly to the conditioning room.”
“.......”
“You look quite solemnly prepared. Then let’s have a brief conversation on the way.”
Click, click.
The sound of the succubus secretary’s high heels echoed through the basement corridor.
“The adventurer group the trainer was captured with was Silver-ranked and consisted of fifteen people in total. Is that correct?”
“There were five women and ten men.”
And I was one of those ten men.
“There are four women and three men still alive, including you.”
“.......”
“Some died while resisting despite being taken prisoner, while others died after refusing to work off their compensation because they couldn’t pay the ransom.”
“Anyone make it back alive?”
“No one yet.”
Of course.
Thinking of the party that had gathered when we entered this place, we simply hadn’t been skilled enough to conquer the dungeon of a Demon King’s army officer.
We had merely been unlucky.
A trap resembling an open gate had happened to be inside the dungeon we entered, and when the gray mist wrapped around us, we were summoned to this dungeon.
After that, well, we were all captured.
“You may kill the men without concern. In fact, you may use them as you please.”
“To what extent?”
“The goblin before the previous trainer—that was about thirty days ago.”
The succubus secretary twisted the corner of her mouth into a faint smirk and continued calmly.
“Because he was enraged at his inability to corrupt the female, he used the male prisoners to gang-rape her.”
“.......”
“He created a situation in which she was betrayed by human men of her own kind. In fact, that woman lost the will to live after being gang-raped by the men who had been her companions.”
“A failure.”
“Yes. She wanted to die, and one of the men eventually killed her.”
“.......”
That was probably the reason the previous trainer, the goblin, had been executed.
Demons died too.
As a human, there would be nothing strange about my head simply being cut off.
“You may use the men however you wish. But the women...you must not kill them or mutilate their bodies.”
“Because they’re humans who will be used as military assets by the Demon King’s army?”
“Yes. They are demons who will one day stand at the forefront of the vampire legion. Sending them out with severed limbs or in such a state would hardly be ‘cool,’ would it?”
Cool.
Though our conversation had been brief, I could roughly understand the ideal picture the vampire princess wanted from a trainer through the succubus secretary.
‘Is it that sort of thing where a female hero falls in a modern superhuman story for adults?’
Usually, she would be unable to think straight while being endlessly fucked, and eventually a womb tattoo would be carved into her, completing her corruption into a true female.
“Of course, if pain needs to accompany the process, that is also an option...”
“If corruption could be forced through that kind of pain, my turn wouldn’t have come.”
The Demon King’s army was already overflowing with experts in violence.
There were also plenty of demons, such as goblins and orcs, who liked to use their cocks on women.
But as a fellow human who understood the limits of the human body, I was the only trainer capable of properly subduing them with a cock and turning them into beings loyal to the demons.
I had to be the only one.
Otherwise, I would die.
“I have one question. How do you determine whether the conditioning has succeeded?”
“We determine it through sexual magic.”
“Sexual magic?”
“We will place a special spell on you.”
The succubus secretary lightly swept her hand toward my eyes.
“Can you see it here?”
The succubus secretary calmly lifted the fabric beneath her shirt.
The line of her waist and smooth abdomen were beautiful enough to make me swallow hard, but the action was so still and formal that it did not suit her figure at all.
“Can you see it?”
“...I can’t.”
“Yes. It’s only natural that you can’t see it right now.”
“......?”
“Here, the ‘lewd mark’ will later begin to shine.”
The lewd mark.
As expected, it seemed to be a womb tattoo.
“When the pink lewd mark is eventually dyed completely black—when it becomes nearly ninety-nine percent stained by lust—that is the moment the mind collapses.”
“.......”
“If we make her swear loyalty as a vampire at that point, she will finally have fallen and become a demon.”
Click.
The succubus secretary stopped at the end of the corridor, in front of a wooden door.
“One more question. Perhaps the last.”
Just before the secretary opened the door, I turned her gaze toward me and asked:
“Has anyone ever succeeded in turning someone into a demon using that method?”
“......Regrettably, no.”
“What?”
“The theory is perfect. This is a form of sexual magic created directly by our master, the vampire princess, through research with the succubi.”
“.......”
“If we had cocks, we would have tested it ourselves. But the vampire legion has relatively few males. The males recruited as trainers were either borrowed from other legions or hired because they claimed to be confident in the task.”
“I see.”
I caught sight of one possible clue to surviving.
“If I become the first person to succeed, then the likelihood that I’ll survive will be even higher, right?”
“That is why our expectations are so great. Conversely speaking...”
“You’re saying I should be prepared for what happens if I fail by falling short of those expectations.”
Grin.
The succubus secretary opened the door.
Step.
The room gave off a bleak, ominous atmosphere.
‘It also feels a little like an AV set.’
It was a place lined with black flooring and gray equipment.
The atmosphere resembled the sort of place in an AV where a woman was held down, tormented harshly, and repeatedly penetrated.
It also seemed to have a deep, dark quality to it.
Rather than a conditioning room, it felt more like an execution chamber—a place where, before being brought before a tribunal for a religious trial in the Middle Ages, witches were tortured by every possible method.
“There are currently four living women. If you succeed in corrupting even one of them, you will immediately become our legion’s rape trainer.”
“.......”
“What will you do?”
“I want to take a look at the four living women first.”
I looked over the objects in the center of the room.
‘They’re all things I know.’
A warrior’s sword. A knight’s helmet. A rogue’s bandana. A priest’s Bible.
There were various other objects as well, but in the end, those were the only belongings that clearly belonged to the living.
“So, how will you carry out the conditioning?”
“The method is... Wait. What are you holding?”
“A pen and paper.”
The succubus secretary had fixed a sheet of paper to a broad wooden board and was holding a quill from which red ink flowed.
“You’re actually going to write it down?”
“Yes.”
“In real time?”
“Yes.”
“You’re going to stand beside me, watch everything I do, and record it all?”
“It’s important.”
“.......”
She was taking this so seriously that she intended to openly watch and document the rape conditioning from the side?
‘I absolutely have to succeed.’
If I survived, then regardless of whether I was on the demons’ side or not, I would be treated as the pioneer of this field.
‘Who else in this other world has ever given me an opportunity like this?’
The modern world and this world were different.
Unlike the information age, when the ceiling might exist but endless paths and possibilities were still open, there were few paths to choose from now, and no lifelines within reach.
I had only one chance.
If I missed this opportunity, all that awaited me was death.
“...Phew. Fine. Write down whatever you want, but unless something truly problematic happens, I’d prefer you not interfere with what I do.”
“Very well. Is there anything else you would like me to do? If it involves physical labor, magic, cleaning, or anything of the sort, you may leave it to me.”
“I’ll ask when necessary. For now, it’s enough to corrupt just one of the four, right?”
“......For the time being, yes.”
The succubus secretary looked at me suspiciously.
She seemed curious about what sort of plan I had in mind.
In that case, I would have to tell her.
“Bring all four of them.”
“......All at once, into this room?”
“That’s right.”
The warrior, the knight, the rogue, and the priest.
All four were women, and in this adventurer party, I had served as a porter and guard—taking watches through the night and the like.
“The previous trainer called them in one at a time...”
“.......”
She must have been worried.
They had gone to the trouble of capturing four women, and she was afraid I might cause all four of them to kill themselves rather than persuading even one.
But it would be fine.
I had also lived twenty-three years in this world, and had learned a thing or two about reading the atmosphere.
“It’ll be fine. I’ll definitely make at least one of them fall.”
“......Even if three of the four die, if one becomes a servant of the Demon King’s army, that would certainly count as a ‘success.’”
The succubus secretary nodded deeply.
“Very well. I’ll bring them all in.”
When the succubus secretary snapped her fingers, figures dressed as prison guards soon appeared with a clatter.
‘Skeleton prison guards?’
Did they use corpses to manage the prisoners?
I couldn’t tell what their builds had been like, but the faces visible between their hats and uniforms looked like human bones.
“Bring all the female prisoners from Sections 31 through 35 on Level C3 of the prison area. Section 34 is already dead, so there should be four in total, from 31 through 35.”
While I briefly wondered whether I would end up like that too if I died—
Clatter.
Four women entered.
The warrior, the knight, the rogue, and the priest.
With tattered sacks like bread bags pulled over their heads, they were dragged barefoot into the conditioning room in nothing but the wide brown one-piece dresses prisoners wore, chains wrapped around them.
They had a few minor wounds, but no bruises or necrotic skin—just the physical condition of people who had been thrown into a holding cell for a few days.
‘I know all of those faces.’
They were the people who had been captured alongside me.
“I’ll get straight to the point.”
And then—
“Only one of the four of you can survive. I hold your lives and deaths in my hands.”
Their reactions were intense.
All four seemed to recognize my voice.
“That’s how things are. You can imagine whatever you want, but shall we start with a light game of truth as an icebreaker? If you lie, your head comes off right then and there.”
I dragged over a chair and sat on it backward, resting my arms over the backrest.
“Raise your hand if you’re not a virgin.”
