You don't know your place.
You don't know your place and you're getting presumptuous.
How much time had passed?
Rubel, who had screamed for a long time, eventually fainted.
After asking Karmīna to move Rubel to her room, Bersia descended a staircase located at the very bottom of the Demon King's castle.
Even after descending for a long time, the circular staircase showed no end.
Now, not a single ray of light entered, and the space was completely plunged into darkness. If others saw it, they would have been afraid to go down further.
But Bersia, as if knowing what lay at the end of the staircase, continued to descend with an unconcerned expression.
After an hour of descending, a single door appeared.
As Bersia cautiously opened the door, a different landscape from the lowest floor unfolded.
It was the inside of a volcano, with lava flowing everywhere.
An ominous magical power permeated the air around, and at the center, a grotesque heart-shaped object pulsed, making the space reverberate.
"......"
Bersia glanced at her wristwatch once, then slowly walked towards the center of the space.
As if sensing her presence, a hand emerged, tearing through the shell of the object at the center.
The hand flailed for a moment between the cracked parts of the object, then tore through the remaining shell. Then, something began to emerge from the completely split object, accompanied by a dark red liquid.
[Aaaahhhhh.......]
A voice, as if ancient despair and rage were mixed together, echoed.
[It's been a long time, Usurper.]
If there was a cruel and immense malice towards the world, would it not take the form of that being?

Bersia thought so, looking at the woman who walked out of the object, twisting her lips into a smile.
High-ranking demon, Harmagedon.
She was the most likely successor to the previous Demon King after he disappeared.
If Bersia had not appeared, she would have truly ascended to the Demon King's throne.
"Yes. It has been a long time. Though I didn't want to see you."
[Do you think I would just let you be after you stole my position?]
"Speak correctly. It wasn't your position, but an empty one that I took."
[Then I will kill you, bitch, and reclaim the throne.]
Hwaaaak!
Harmagedon, who had instantly appeared before Bersia, reached out to strangle her.
However, her hand could not reach Bersia's neck.
The Sealing Magic on Harmagedon's wrist prevented it.
[Kraaaahhhhh——!!]
Despite the Sealing Magic, immense magical power erupted from Harmagedon's entire body.
Before she became the Demon King, during her time as a Saintess, Bersia had seen a certain fate.
The fate where Harmagedon, upon becoming the Demon King, brutally massacred all humans.
"......You are not to run wild yet."
Harmagedon, as the Demon King, was too powerful.
In any timeline Bersia saw, humans could not contend with Harmagedon.
No matter what they tried, they only suffered brutal defeats.
Except for one single timeline.
That was why Bersia had begun this terrible Regression cycle.
To surpass Harmagedon before she became the Demon King, and to ascend to the Demon King's throne herself.
And then to instill hatred in Rubel, making her cultivate enough strength to be able to strike Bersia down.
That way, the being that would inevitably emerge would one day be cut down.
[Bersiaaaaaa——!!!]
"So don't scream so loudly and just go back to sleep quietly."
Bersia created a sword out of magical power and stabbed Harmagedon's heart.
Pwooook!
[Kuh-huhk!!]
Harmagedon's face contorted in pain as she gushed blood.
[Do you think, you bitch, that something will change just because you do this...? A puppet of fate....]
"I don't know. But even so, I cannot leave you be and let Rubel die."
[......You will realize someday. That no matter how many times you regress, nothing will change.]
With an unpleasant laugh, Harmagedon spat out a curse, and her body began to be pulled back towards the central object.
[Someday, I will surely kill both of you. I promise to give you the worst death then.... Bersia.......]
With those words, Harmagedon was completely pulled into the central object.
The split object had restored itself to the shape of a heart.
"......I will never let that happen."
Bersia turned away from the object and walked towards the door, speaking.
"Because even if I die, I will somehow save Rubel no matter what."
***
"Ugh......"
When I opened my eyes, the ceiling of the bedroom, which I had grown somewhat accustomed to, came into view.
"Agh......."
The places Bersia had hit me yesterday ached.
However, apart from that, there was no significant hindrance to moving my body.
Thanks to the God's Blessing I received when I became a Hero, my body recovered quickly during sleep as long as it wasn't an instant death.
Of course, receiving direct healing magic would be better, but.
'......Should I lie down a little longer?'
I decided to rest a little longer, judging that my body hadn't fully recovered yet.
It was frustrating that even after all that, I couldn't inflict significant damage on Bersia....
In this state, proper training wouldn't be possible anyway.
I decided to rest thoroughly and train my body after my injuries had fully healed.
Just as I was about to close my eyes and try to sleep.
Bwolk!
The room door burst open roughly, and Bersia entered.
"...Bersia?"
"A night's rest should be enough. Your body must have recovered to some extent, so I shall exact the price for losing the duel."
"Now, you mean?"
"Yes. I will copulate with you right now."
Saying so, Bersia immediately climbed onto the bed where I was lying.
Bersia quickly closed the distance until our breaths mingled, then stared intently at me with her characteristic vacant eyes.
Soon, she grabbed my chin and forced my lips to meet hers.
"Ughb......!?"
I couldn't push her away at all.
No matter how hard I tried to push, Bersia's body didn't budge.
"Ugh...! U, bbb.... Wooob!!"
"...Don't resist and stay still. Isn't this the price for losing the duel?"
"You bitch, you...! Ughhh...!!"
"If you didn't want this, shouldn't you have won?"
As our lips met, Bersia's tongue pushed through the parted gap.
Bersia rummaged all over my mouth, intertwining with my tongue inside.
"Heub, ub...! Ughk, ugh...! Heub...!"
Kissing the enemy I wanted to tear to shreds.
I hated it.
I hated it so much that if I had a dagger in my hand right now, I would choose to commit suicide.
I hated it that much, truly.
Yet, this damned body, for some reason, was getting wet between my legs.
"Ugh-eup.... Heu, ub......."
"Chureup, jjyueup...❤ Jjo-ok...❤"
Did she notice my body's reaction?
Bersia wrapped her arms around my neck.
She pulled me in tightly, making it impossible for me to even pull my lips away.
'I can't, breatheee.......'
My mind gradually blurred due to improper breathing.
An unbearable pain arose in my chest, making it difficult to endure.
So I hit her shoulder hard, signaling Bersia to let go.
But this damned bitch only pulled her lips away after kissing me for a long time.
"Phaaa......."
"Heek, huhk....... Huhk, huhk...!!"
"You look good, Rubel. A Hero, kissing the Demon King and getting her pussy wet."
Bersia wore a twisted smile and pressed her palm against my underwear.
"Kkeu-heuk!?"
"If I had known this, I would have made you a succubus. Huhu... That look would suit you a little better."
"Shu, shut up...!! Who said I got my pussy wet!!"
"Didn't you get it this wet?"
Bersia lifted her palm from my underwear.
Then, a sticky fluid stretched long between her palm and my underwear.
"Look. If this isn't love juice, then what is it?"
"Th, that's......."
"You're utterly lewd, Rubel. It would have been great if your comrades had seen this."
"Don't you dare mention my comrades with that filthy mouth!!"
At my words, Bersia pondered for a moment, making a 'hmm' sound.
Then, she slapped my cheek fiercely.
Jjaaaak——!!
"Kkeu-heu-euk!?"
"A loser talks too much. Do you truly not realize that I'm being considerate by letting you be like this, even though I could have turned you into a flesh toilet long ago?"

Hot blood streamed from my busted lip.
The slapped area swelled red, and the intense pain in my cheek made it hard to keep my wits about me.
"I intended to treat you a little gently, seeing as you were injured yesterday... but you don't know your place and dare to defy me."
"You damned, bitch...!!"
"...Still haven't come to your senses, I see."
Jjaaaak!!
Bersia sighed softly, then slapped my cheek hard once more, lifted her skirt, and spoke.
"Well. Disobedient beasts have always been disciplined with a stick."
"You bitch, what are you trying to do...!!"
"What am I doing?"
Bersia grinned.
She grabbed my waist tightly and plunged the dick that was revealed when her skirt was lifted into my hole.
"Oh-go-go-gok!?❤"
"You ask such obvious questions, Rubel."
