The Demon King Who Was Supposed to Lose Ended Up Defeating the Targets, and Now the Heroine Has Been Sent as a Sacrifice - Chapter 25

Chapter 25: The Demon King Supposed to Lose, Becomes the Stud

I returned to Avan Castle with the unconscious Dott, where I reunited with Elsia.

When Elsia saw Dott, her face twisted into a smile—a wicked grin that was, by far, the most sinister I had ever seen from her. It was so evil, it was almost refreshing. 

The contrast to her usual expression was a bit frightening.

I thought she looked much cuter when she smiled normally…

But this was for her revenge.

Since I’m not the type to say unnecessary things, I decided to quietly watch over Elsia.

“HmmHmmHm~n♪”

Humming a tune, Elsia bound Dott’s hands and feet and tied him to a chair.

She even made sure to equip him with restraints that sealed his magic.

“Lord Diablo.”

“Yes?”

“When he wakes up, can we flirt in front of him?”

“…You’re going to show off?”

“Yes ♡ Maybe we should even go all the way!!”

Elsia was being very forward. My demonic sword was ready to go too.

“Ugh, where… am I?”

“Elsia, it seems he woke up.”

“El, sia?”

Dott, who had been looking around with unfocused eyes, snapped to attention as soon as he heard Elsia’s name. And so, Elsia and Dott finally had their emotional reunion.

Elsia spoke to him with a smile.

“It’s been a while, Sir Dott.”

“Elsia, is it really you? Truly?”

“My, how terrible. Have you forgotten my appearance just because we haven’t seen each other for a while?”

“No, no!! There’s no way I could forget about you!!”

“…Sir Dott, do you still love me?”

Dott answered Elsia’s question without hesitation.

“Of course I do!! I’ve changed because of you!! There’s no way I wouldn’t love you!!”

“…I see. That’s good to hear.”

Dott had originally been a flirt who chased after multiple girls. 

This behavior stemmed from his upbringing in the Caiman family, which had a long history of producing knights.

He was raised under strict discipline by his parents, who placed high expectations on him as the heir to the family.

However, Dott’s father, who was the captain of the knights, died protecting a subordinate during a monster hunt. His mother, who was the vice-captain at the time, took over the captain’s role. But the stress from managing the transition and training new recruits took a toll on her health, and she fell ill.

With his strict parents no longer watching over him, Dott, in reaction to the years of repression, turned into a flirt, chasing after multiple women.

It was none other than Elsia who reformed the flirtatious Dott.

When Dott tried to flirt with Elsia in his usual manner, she firmly rebuked him, saying, “I dislike people like you who treat women as accessories.”

There wasn’t a single woman that Dott couldn’t win over before, so his pride was hurt. That was the start of Dott and Elsia’s interactions.

Eventually, Dott genuinely fell for the kind-hearted Elsia.

And even now, Dott is still in love with Elsia.

“I see, that’s good. It’ll make my revenge easier.”

Elsia said with a smile.

When Dott heard the word “revenge,” his face twisted as if he had bitten into something bitter. Perhaps he regretted abandoning Elsia.

Even if he did, it was far too late for regrets.

Elsia clung to my arm, pressing her excessively ample chest against me.

Whoa, so soft!!

“Oh, but I am grateful to you and your friends, Sir Dott. Thanks to you, I was able to meet a wonderful man. Ahn ♡ Oh, Lord Diablo, please wait just a little longer.”

“Wasn’t it you who suggested we show off our love to him?”

“I did say that ♡ Ahn ♡ Fufu, I understand. Sorry, Sir Dott. It seems Lord Diablo can’t wait any longer, so you just watch from there, okay?”

Taking Elsia’s words as the signal to start, I reached out to her without hesitation.

Side: Dott

What am I being forced to watch?

The girl I longed to see again, the one I love, is being pleasured by the despised Demon King. He’s touching her pale skin without hesitation, exploring every inch of her body.

This scene is burned into my mind, whether I like it or not.

“Ahn ♡ Ahn ♡ Lord Diablo ♡ You’re rougher than usual ♡ Are you jealous because I was talking to my ex? That’s so cute ♡”

“As if I’d be jealous.”

That ‘thing,’ larger and thicker than Elsia’s arm, was thrusting deep into her, and she was accepting it with nothing but pure bliss.

A male, driven by instinct, and a female, welcoming him.

They were like animals.

There was an Elsia in front of me that no one knew, not even I did.

But, as someone who used to be obsessed with fooling around with women, I couldn’t help but understand.

The expression on Elsia’s face was one a woman only shows to someone she has completely given her heart and body to.

“Pfft, haha. Look, Lord Diablo. Sir Dott…”

Suddenly, Elsia looked at me and laughed.

Her gaze was fixed on the pathetic sight of me, aroused despite watching my lover being taken away.

“What do you mean, you love me? If you truly loved me, you wouldn’t be getting excited watching me being embraced by someone else, would you?”

“T-This is…”

“Oh, no need for excuses. I understand how you really feel now. You must be some kind of pervert who gets excited when the girl you love is taken from you, right?”

The girl I love mocked me, laughing at my disgrace.

“Fufu, Sir Dott. Just between you and me, the Demon King here is a bad man who also has his way with other girls besides me.”

“W-What…”

“Remember what I once told you? ‘I hate people who treat women like accessories.’ You were awful, weren’t you? But this man, he loves each one of us deeply. Unlike you.”

The Elsia who once changed me had already been changed herself.

I quietly closed my eyes.

If I kept looking at this reality, I felt like I might lose my mind.

But Elsia, of all people, wouldn’t allow that.

“Don’t you dare close your eyes on your own.”

“Ugh!”

Suddenly, I felt a hand around my neck, forcing me to open my eyes.

Even while being embraced by the Demon King, Elsia reached out, grabbing my neck, and was genuinely choking me.

I couldn’t breathe. It was unbearable.

“Ahh ♡ Look, Lord Diablo ♡ Sir Dott—no, it’s too much trouble to call him by name anymore ♡ This human seems to be getting excited from being choked.”

“Ah, yes. I read somewhere that humans exhibit reproductive instincts when they sense death approaching.”

Elsia mocked me with a laugh.

And the Demon King looked at me with a kind of pity, as if he almost felt sorry for me.

Don’t you dare!!

“Demon King…!! You, and only you, I will never forgive!!”

“Huh? Me?”

That’s right. It’s all because of the Demon King.

If it weren’t for him, we could have been happy.

I was supposed to be the knight who protected Elsia.

“Hmph!!”

“!! Gah—!!”

A sharp pain shot through my lower body.

Elsia mercilessly kicked my now enlarged ‘thing.’

The dull pain made me writhe, and even though I was tied to the chair, I couldn’t help but hunch over in agony.

Elsia grabbed my hair roughly and forced my head up.

“You’re truly hopeless. Blaming Lord Diablo for your own inadequacy. I’m utterly ashamed that I ever liked you, even for a moment.”

For a brief moment, Elsia’s face showed disappointment.

But that expression quickly vanished.

Her eyes turned cold, as if she was looking at a worthless pebble on the side of the road, completely devoid of interest.

“Ah… ah…”

“Well, I’m not interested anymore, so it doesn’t really matter. Lord Diablo, shall we continue?”

“…ait.”

Before I realized it, I was forcing the words out.

“Yes?”

“Kill me. Just kill me already.”

I couldn’t stand living anymore. 

If I had to keep watching her be with the Demon King, I’d rather just die.

But Elsia showed me no mercy.

“Don’t worry. I wouldn’t do something as cruel as killing you. I actually have two gifts for you.”

“…W-What?”

As she spoke, Elsia pulled out something that looked like a restraint.

“This is called a chastity belt. Knights and soldiers would make their wives wear them during long expeditions. This one’s for men, though.”

“W-What are you…?”

“Once you’re wearing this, you won’t even be able to relieve yourself. It’s going to be very tough, isn’t it?”

Elsia forcefully put it on me.

“If I feel like it, I wouldn’t mind letting you watch us again. Of course, whether or not the chastity belt comes off is up to Lord Diablo. Who knows, you might even get the chance to secretly be with me again?”

“ELSIA.”

“Ahn ♡ Please don’t be mad, Lord Diablo. I was just joking, of course.”

“…You’re getting punished today.”

“Fufu, yes ♡ Please punish this naughty girl who hinted at cheating ♡ Oh, and here’s the key to the chastity belt—whoops!”

Elsia crushed the key to my chastity belt in her hand, destroying it.

I was now permanently trapped in this state.

Then, as if she had just remembered something, Elsia clapped her hands.

“Oh, the other gift is my blood. It wouldn’t be fun if you decided to end it all, so I’ll turn you into an undead. Don’t worry, I’ll let you keep your consciousness.”

Elsia smiled.

But it wasn’t the gentle smile I used to love. It was a wicked grin, one meant to torment.

“Make sure you savor the despair, alright?”

Ah, God.

All I could do was pray that my mind would break as quickly as possible.
