What should one call the human heart? It is truly vile.
When someone else experiences something good, people grow envious and jealous.
When I experience something good, I want to be the only one who enjoys that privilege.
When someone else suffers something bad, I hope it does not bring harm to me.
And when I suffer something bad, I find myself thinking that I cannot be the only one to suffer like this.
Of course, we call people with such dispositions “vile.”
Out of ten people, perhaps five would think that way.
And among those five, there are times when one of them takes that thought—“I can’t be the only one to suffer”—and actually puts it into action.
That is what is happening now.
“Dahlia. Do you wish to verify Knightess Eris’s faith?”
“That is so.”
Having washed all the blood from herself in the shower room, Dahlia stood before me wearing a standard prison uniform (brand-new) kept in the trainer’s office.
“Is that not the role assigned to me?”
“It is not necessarily limited to that.”
Dahlia might wish for it to be so, but from my perspective, the matter was a little different.
“Eris’s pussy is mediocre, but it is still unclear whether she’ll fall because of a matter of faith.”
“.......”
“You seem to want to bear witness to Eris’s faith, but do you really have to use the same method on Eris that you used on yourself? You don’t.”
There was one method for a priestess.
And there was another method for a knightess.
“Or what? Since you were gang-raped by several men, does Eris also have to be gang-raped by several people?”
“That is....”
Perhaps that was the greater factor.
“She’s already been raped by me, hasn’t she?”
“......Is that so.”
Dahlia’s dissatisfaction eased slightly.
Apparently, she felt a certain kinship with Eris over the fact that Eris had been raped—not anything else, but that.
Thank goodness.
‘She didn’t see how Eris was raped.’
Humans sometimes judge others according to their own experiences.
Since I had merely said that I had “raped” her, Dahlia would assume that Eris had experienced something similar to what she herself had suffered in prison.
‘It was rape, technically.’
I had licked her pussy, minimized the pain of her virgin pussy as much as possible, and even lavished her with caresses meant to let her feel nothing but pleasure. But it was still rape.
Even if it had been modern, sweet-guy sex with a beloved lover, I had cuffed her to a bed in the trainer’s office and thrust my cock into her. It was rape.
‘I’ll have to keep it a secret for now.’
If I told Dahlia how Eris had been raped, she might fly into a rage.
She might become jealous as a woman, wondering why I had treated Eris that way after making her suffer like that.
It was not really a matter of her feelings toward me, but of how she had been treated.
I could say that Eris was a virgin, so of course she had been treated differently, but—
‘What the trainer needs is an existence corrupted into a demon, not a virgin pussy.’
For now, Dahlia was more valuable than Eris.
If I were asked which of them was more advantageous to my “survival,” I could state without hesitation that it was Dahlia.
‘I don’t know what the Vampire Princess will think, but Dahlia is the one who is useful as an immediate result right before my eyes.’
A woman who had been deflowered and gang-raped, but reborn as a vampire.
An existence whose virginity had been taken by the trainer, but who had not yet become a demon.
“Are you going to turn Eris into a demon?”
“There is no reason not to.”
“That is why I said I would help you.”
“How?”
“.......”
Whisper, whisper.
Dahlia made a proposal.
To me, that proposal was somewhat absurd—
“You.”
“.......”
“Are you doing this because you want to have sex with me?”
“That would also be one method, would it not?”
Dahlia spoke without the slightest change in her expression.
“To be honest, if I am to prove my faith, I must continue to survive, must I not?”
“So you’re going to suck my cock?”
“I would like to bite it off, but if I did that, I would no longer be able to continue executing apostates.”
Dahlia wanted it.
“Rape me. Then threaten Eris.”
“Threaten her by saying, ‘If you do not willingly become a demon, I will rape Dahlia to death’?”
She wanted to use her own body to bear witness to the faith of another woman.
“Aren’t you curious? Whether she would abandon her faith in the goddess to save a companion—or leave her former companion to be raped to death in order to preserve her faith in the goddess.”
“.......”
The proposal was certainly interesting.
But—
“It isn’t because I took Eris’s virginity, but your proposal is too extreme.”
Forcing Eris into such a binary choice right now made me think, “Do we really need to?”
“Instead, if any women are taken prisoner next time, we can try your proposal then.”
“Hmm....”
“Or what, are you doing this because you want to have sex with me? If you told me honestly, I might even let you have my cock.”
“Hmph.”
Dahlia frowned.
She had been subtly flirting with me from the beginning, asking, “Want to try it sometime?” But Dahlia neither affirmed nor denied it.
‘Perhaps I should wait and see for now.’
Once the succubus secretary arrived, I could operate them separately anyway.
There was no need to keep the two of them together and use them in the same place.
I already had one plan in mind.
‘A two-track strategy.’
Virgins with virgins.
Non-virgins with non-virgins.
The virgins would become non-virgins once I penetrated them anyway, but a woman who became a non-virgin through me and a woman who had been a non-virgin from the start were entirely different matters.
“For now—”
Creak.
The door opened.
I was about to leisurely welcome the succubus secretary—
“......?”
Right before my eyes.
“......Huh?”
“Trainer.”
The white-haired, red-eyed woman—the Vampire Princess—had appeared.
Dressed in a black dress that looked fit for attending a funeral, she gave me a sidelong glance, then turned her head and slowly looked Dahlia up and down.
“.......”
“......!!”
“Kneel.”
At that single look, Dahlia fell to both knees.
“Ah, k, ugh...!”
Her body trembled violently, sweat poured down, and the fingernails of the hand resting on her thigh dug into her flesh.
“An excellent result. So, even after becoming a vampire, your faith in the goddess remains unchanged?”
“Ghk, ugh, uuuugh...!”
Dahlia suffered.
She suffered as though her intestines and heart were caught in the grip of magical hands and squeezed.
“From the moment you became a vampire, you were bound to obey my commands. That is the fate of a vampire—a vampire reborn through the blood of the Vampire Progenitor.”
Just as I thought.
‘Do all demons corrupted through training become absolutely subservient to the Vampire Princess?’
I had anticipated it.
My role was training and corruption, not putting the results to use.
It was a little disappointing and bitter that my first achievement had immediately become an existence that obeyed the Vampire Princess’s commands, but—
‘Let’s not think that way.’
Dahlia was human, but at the same time, she was an object and a subordinate.
What mattered was my survival.
“Trainer.”
“Yes, yes!”
“Do you want this woman?”
The Vampire Princess placed a hand atop Dahlia’s head and turned her gaze toward me.
“Since you were the one who turned this woman into a vampire, are you about to say that you want her given to you as your property?”
“That, that is....”
“Oh?”
The Vampire Princess approached me.
“Really?”
“If, if it pleases you.”
Death approached.
The red hand clutching my throat was made of magical power, yet it possessed physical force as it slowly dug into my neck.
The moment the Vampire Princess seized and strangled my throat—
My neck would snap just like that.
Even if I regressed, the result would be the same.
It was my instinct as an adventurer, as a human, and as prey.
There was nothing I could do to survive this woman.
Not through physical means.
Then, naturally, I had to use another method.
“If it would help create new fallen ones based on the first corrupted subject—guh!”
“Continue.”
The pressure eased slightly.
‘Got her. She took the bait.’
The Vampire Princess looked at me impassively, but the fact that her attention was fixed on me meant she was interested in our conversation.
“This woman did not abandon her faith in the goddess even after becoming a demon.”
“Hmm.”
“And even after becoming a demon, she wishes to pass judgment upon those who have abandoned their faith in the goddess.”
“So?”
“I humbly dare to propose that you use this woman as the ‘executioner’ who executes the prisoners.”
“An executioner.”
The Vampire Princess toyed with her lips with one finger.
“How do you intend to execute them?”
“Those who have abandoned the goddess will be executed according to the Master’s method. Though I have personally beaten this one to death with a mace for the sake of appeasing her anger, those who must be ‘judged’ should have their hearts torn out, and their blood put to use for the legion.”
“Judged?”
She asked.
Since I had deliberately emphasized the word, the Vampire Princess immediately caught its nuance.
“Yes. We will use the method that corrupted this woman to produce a second and third corrupted subject.”
“Hmm....”
“Since one method has already been verified, we can apply the same method to other prisoners and corrupt them as well.”
“What do you think the success rate will be?”
It worked.
The word “success rate” had come from the Vampire Princess’s mouth.
“It will differ depending on who the prisoner is.”
“...I want an exact figure.”
Ah.
This woman was a science type.
“Do you want statistics? Then I shall prepare a sample for you so that I can compile statistics myself.”
“A sample.”
“There were four female prisoners. We succeeded in training and corrupting one of them, so in the extreme case, we could call it twenty-five percent.”
“.......”
“But this woman—”
I slowly approached Dahlia and placed both hands on her shoulders.
“Based on Dahlia’s case, if we conduct the same experiment on priestesses and one out of ten falls like Dahlia, would that not make the success rate approximately ten percent?”
“You propose conducting experiments through this training?”
“Yes.”
I held Dahlia tightly.
“And depending on the prisoner’s case, I shall establish a customized training method suited to that case as a theory.”
“.......”
“According to the method desired by the Master.”
One thing.
“Until the day when ninety-nine percent of humanity falls.”
From the moment the Vampire Princess entered, I had instinctively realized one thing.
“I shall work for the Master.”
The Vampire Princess had clearly demonstrated her dominance as the strong over both Dahlia and me, but—
‘She has no intention of killing us.’
If she had intended to kill me, her eyes would not have looked like that.
“...Interesting.”
The Vampire Princess—
“Trainer. What is your name?”
—twisted the corners of her mouth into a smile.
“Your humble servant.”
My name was—
“Whatever the Master calls me becomes my name, but I call myself ‘Azazel.’”
“Is that so?”
The Vampire Princess snapped her fingers.
“Then.”
Red magical power instantly formed a chair. The Vampire Princess sat down, crossing her legs.
“Trainer Azazel. I shall ascertain how loyal an existence you truly are to me and confirm your sincerity.”
Rustle.
Her shoe fell downward.
“Trainer Azazel.”
At the same time, a flawless, jade-white foot was revealed before me.
“Kneel.”
“......!”
Even though I was not a vampire, I had no choice but to kneel at her command.
An order?
No—because I had been bewitched by something.
“And.”
The Vampire Princess extended her foot toward me.
“Kiss my foot and prove your loyalty.”
For reference—
in this world, kissing the feet was the act by which a slave displayed the highest form of obedience to their master.
“Master.”
But—
“Would a mere kiss be enough?”
I stuck out my tongue.
