The Demon King Who Was Supposed to Lose Ended Up Defeating the Targets, and Now the Heroine Has Been Sent as a Sacrifice - Chapter 09

Chapter 09: The Demon King Supposed to Lose, Performs a Moonsault Sliding Dogeza

I messed up.

When I regained my thoughts that I had once abandoned, Mana was sleeping in my arms.

Her eyes slowly opened.

“Diablo…?”

“…Yes, it’s Diablo.”

Remembering last night’s events, Mana’s face turned bright red.

“W-What have I done to my daughter’s husband!? I-I’m sorry!!”

“Ah, no, please don’t apologize!! I couldn’t resist either…”

I quickly stopped Mana from trying to bow deeply in apology.

“…For now, let’s head to the castle.”

“I can’t face her… She’s sharp, she’ll figure it out even if we try to hide it.”

“Well, I’ll apologize as much as I need to.”

I don’t want their reunion to be ruined because of me.

If I take full responsibility for what happened, their relationship shouldn’t worsen…

But then Elsia would hate me!!

Argh.

Isn’t there some way to keep Elsia from hating me and not ruin their relationship?

Even if we try to hide it, she’ll find out, so I think it’s better to apologize before that happens…

“Ah, before that, please use this.”

“Oh, what’s that?”

“It’s an item called a Rebirth Stone that I picked up in the dungeon. It can change your species. There are many at the Demon King Castle who see humans as food, so it’s best to change your species before we go.”

It’s a valuable item, but I have a few of them.

The question is what species to change Mana into. Should I make her a vampire like Elsia?

“Can you let me have that for a moment? If possible, I’d like to choose for myself.”

So, I handed the Rebirth Stone to Mana.

Mana stared at the Rebirth Stone for a while, seemingly deciding on what to become.

Without hesitation, Mana used the Rebirth Stone.

“How do I look?”

“A Fallen Angel, huh? That’s an unusual choice.”

Mana chose to become a Fallen Angel.

Originally, Fallen Angels were descendants of angels who were once apostles of the goddess but committed sins and were banished to the earth.

Their numbers are extremely few, and there isn’t a single one in the Demon King’s army.

Looking through my memories as the Demon King Diablo, I recall knowing a few in the past, but they all passed away.

Although there’s no concrete evidence, it’s possible that the fallen angels are an extinct species.

Fallen angels have distinct physical features, like the jet-black wings growing from their waists. 

A cracked halo of light floats above their heads, giving off a somewhat sacred aura.

“But why a Fallen Angel?”

“It’s a childish reason for someone my age, but I wanted to fly in the sky. Also, Elsia gets embarrassed when I give her matching things.”

“I see. So that’s why you didn’t choose a vampire, even though they can fly too.”

It seems she had a good reason.

Mana and I left the forest and flew towards the Demon King Castle.

I thought I’d come up with an excuse for Elsia while flying.

But no good ideas came to mind, and we arrived at the castle just like that. 

Almost at the same time, Elsia returned from the Kingdom of Alvera.

There was no other choice.

I decided to use my special technique from my previous life, which I hadn’t used since becoming the Demon King.

“I’m truly sorry!!”

This was my ultimate technique from my past life.

It was a shocking move that left no room for the other person to think, only to apologize profusely.

I maximized the use of my Demon King physical abilities.

If I had to name it, it would be the Moonsault Sliding Dogeza.

“…Did something happen?”

I explained the situation to the confused Elsia honestly.

And I made it sound as much like my fault as possible.

Mana tried to correct me, but every time she did, I spoke even more quickly to stop her.

“…I see. So, while I was in the Kingdom of Alvera, you and my mom had sex, Lord Diablo?”

“No, it was more like I forced—”

“Is that true?”

“Uh, yes.”

“Is it really the truth?”

“…”

The pressure, the pressure is intense!!

“…Sigh. Lord Diablo, you’re bad at lying. You have a habit of falling silent when you’re in trouble; you should stop that.”

“No, it’s not like that—”

“Let me guess, my mom suggested drinking, and then she got drunk and seduced you?”

““Gulp””

Is she a mind reader!?

Elsia’s intuition is terrifyingly sharp. Is this even intuition?

“It’s also my fault for not warning you about my mom’s bad drinking habits. And Mom—”

“Y-Yes!! What is it, Elsia?”

“Mom, you like Lord Diablo, don’t you?”

At Elsia’s pointed question, Mana’s gentle demeanor shattered as she flinched.

“Well, yes, I do. I think he’s wonderful. Strong, kind, handsome, passionate…”

“…I’ve always been a burden to you, so I want to support your love. But—”

Suddenly, Elsia hugged me tightly.

My head was buried in Elsia’s large, soft breasts.

Oh, oh, maybe because she just got back, there’s a slightly sweaty, sweet scent!!

“Lord Diablo’s main wife is me. I won’t give up that position.”

“Elsia, aren’t you angry? About me being with your mother…”

“I think I love you more than I realized, Lord Diablo. Of course, I’m jealous. It’s complicated, though…”

Elsia gave a wry smile.

“Lord Diablo, you’re the Demon King. Isn’t it normal for a king to have many wives? At least in the Kingdom of Alvera, the king has many concubines besides the main wife.”

“Well, that’s true, I guess?”

Having been an ordinary person in my past life, I had completely forgotten, but is that how it works for kings? Are harems a thing?!

“I once had a relationship with the prince. So, I was prepared for this.”

“I see.”

“…Lord Diablo, you’re very charming. Our relationship started with a contract, so I don’t have the right to stop you.”

Elsia looked a bit sad as she said this.

“Besides, I always thought you’d eventually do something naughty with other women. You’re a bit of a pervert.”

“I can’t deny that.”

“Well, I didn’t expect the other woman to be my mom, though… Anyway, there’s no need to apologize. I have no intention of losing to her.”

“I-I won’t lose either!!” 

In response to Elsia, Mana hugged me, pressing my head into her large breasts as well.

I-Is this… is this a harem?! Ugh, my demonic sword is about to go out of control!!

“…Ah ♡ Mou, Lord Diablo!!”

“Oh my… Ufufu, you’re so young, Diablo ♪”

“…”

I hesitantly reached out and touched their large breasts.

“Hyan ♡”

“Ahn ♡”

Both were soft, but the feeling was different.

Elsia’s breasts were like bouncy mochi, while Mana’s were like fluffy cotton candy.

However, at the tips of those fruits, the slightly hardened spots were identical in color and shape for mother and daughter.

“Lord Diablo, who will you choose? If you pick me, I’ll wear something naughty for you.”

“Diablo, let’s do it with Mama.”

Elsia, usually shy about intimacy, became assertive to compete with Mana.

Choosing between them was a tough decision.

Do I really have to choose between these two pairs of breasts?

After much deliberation, I said…

“Both.”

I took them both to the bed and kept going until they passed out.

Elsia seemed to understand that I might marry multiple women, so why not just create my own harem?

Oh, but I don’t mean collecting girls like objects.

I genuinely want to love and make each one of them happy.

By the way, having a mother-daughter combo is the best.
