The Demon King Who Was Supposed to Lose Ended Up Defeating the Targets, and Now the Heroine Has Been Sent as a Sacrifice - Chapter 02

Chapter 02: The Demon King Supposed to Lose, Remembers His Past Life

Let me tell you about the time I regained the memories of my past life.

It was a night with a red moon, the same night when the seal, placed by a saint hundreds of years ago, had weakened and finally broke.

“My Lord, we, the Demon King army, have been eagerly awaiting your awakening.”

“…Balzac?”

“Yes! This is your first servant! Balzac at your service!”

When I woke up, my head was in complete disarray.

I had two sets of memories: one as the Demon King who had nearly wiped out humanity centuries ago, and the other as an ordinary university student in a country called Japan.

I was bewildered by the experience of reincarnation and stood frozen for a while.

But, there was no point in lamenting over my rebirth.

I decided to accept myself as I was and live this new life to the fullest.

“Like that would happen!!”

I shouted instinctively.

Reincarnation? Are you kidding me? I had just graduated from a good university and was about to start a job at a top company!

I hadn’t even had the chance to repay my parents for their kindness or see my sister in her wedding dress!

Damn it! Why did this have to happen!?

As I panicked internally, I noticed that the surroundings had gone completely silent.

“Um, my Lord, have I perhaps committed some kind of disrespect…?”

“Huh? Oh, no, it’s not that…”

My subordinate Balzac was trembling.

At first glance, he looked like a regular young man with glasses, but he wasn’t human.

He belonged to the demon race, one of the highest-ranking among the many kinds of demons, with menacing horns on his head and bat-like wings on his back.

He seemed familiar, yet unfamiliar at the same time.

Of course, he was the demon who had served me, the Demon King, even before I was sealed, so it was natural to recognize him.

But it felt like I had seen him somewhere in my past life memories.

I was sure I had seen him somewhere, but I couldn’t recall where.

Where was it?

“Oh, my Lord. Please, in exchange for my life, calm your anger!”

“Hey, wait! What are you doing!?”

“Do not stop me! If I have displeased my liege, I should die here!”

Balzac was about to plunge his sharp claws into his own heart, and I hurriedly stopped him.

Even then, he still tried to end his life, so I quickly gave him an order.

“Stop that!! When did I ever order you to die?! You are absolutely not allowed to die without my command!”

“Oh, my liege… Such mercy… Are you really forgiving this foolish me…?”

Then, a cheer erupted.

It was the voices of the countless demons and monsters standing behind Balzac.

Wow, there were a lot of them…

And this scene seemed oddly familiar.

Oh right, it was a scene from that otome game my sister recommended.

…Huh?

“Balzac, do you have a mirror?”

“A mirror, you say?”

“Yes! Hurry up and get one!”

“Y-Yes! Right away!”

Balzac ordered one of his subordinates to bring a mirror.

“…Seriously? So this is the world of ‘The Saintess and the Five Heroes’…”

“My Lord?”

Seeing my reflection in the mirror, I remembered everything.

Gray hair that looked like tarnished silver, and two golden eyes.

Two horns sprouted from my head, emitting an evil aura, four pairs of jet-black wings extended from my back, and a dragon’s tail stretched out from my waist.

And I looked handsome. Compared to my plain old face from my previous life, it was like night and day.

It was a very familiar appearance.

The final boss of the otome game ‘The Saintess and the Five Heroes’ that my sister recommended to me, the Demon King.

If I remember correctly, his name was…

“The Demon King, Diablo.”

In the game’s lore, he was a calamity that almost wiped out humanity centuries ago.

But in actual gameplay, even the heroine or love interests with little leveling could defeat him.

If they couldn’t defeat him, the heroine would seal him after a certain number of turns.

“Seriously? It’s Dia-chan?”

Because of his extreme weakness compared to his backstory, Diablo was affectionately called “Dia-chan” on the internet.

The otome game was highly regarded, but he was infamous as a disappointing final boss in the adventure part of the game.

Then I suddenly remembered.

“Wait, isn’t this bad? When Dia-chan revives, the heroine and her love interests are supposed to come and defeat him when he’s weak…”

This is bad. Really bad. I can’t just sit here.

If I don’t take action quickly, my second life will end soon.

But wait, that’s not good either!!

If the Demon King, which is me, isn’t defeated or sealed, the heroine can’t reach the super ultra happy end route, right!?

The heroine is a girl from a commoner background, and all the love interests are royalty or nobles.

To be with the love interests, the heroine doesn’t need to defeat the Demon King, but if they want a happy ending blessed by everyone, they definitely have to come and defeat the Demon King.

It’s not certain that the heroine will come to defeat me, but it’s better to be prepared.

Or maybe, if the heroine and her group do come, I could just let them win on purpose and live as an ordinary demon instead of the Demon King.

After all, I was just a regular university student in my previous life. Being a Demon King is definitely impossible for me.

Alright, I’ve decided.

I’ll make sure to be defeated in a convincing way and then live as an ordinary demon! 

To do that, I need to become strong enough so I don’t get really defeated by accident, and I need good acting skills!

As for acting, I have the skills I learned from being in the drama club during high school, so that’s not a problem.

So then…

“Balzac, I’m going out for a bit.”

“Huh? My Lord? Wait, my Lord! Where are you going?”

“I’ll be back soon! It’s just leveling up!”

I stood up quickly and started moving immediately.

I soared through the air with enough force to break through the ceiling of the Demon King’s castle and headed for the dungeon.

There, I defeated various monsters and leveled up.

I also quickly solved the problems of the slime, goblin, and kobold tribes. I made friends with the succubi, improving the overall strength of the Demon King’s army.

In just a few months, the heroine and her companions came to defeat me.

And now, the present.

The heroine Elsia, whom I had turned back in defeat, was sent to me as a sacrifice.

What should I do? Really, what should I do?

“My Lord, how should we prepare the saintess?”

“Wait, eat her?”

“Saints are rare and high-quality delicacies, you know? Eating her would surely enhance your power, my Lord. A thousand years ago, you also mentioned wanting to taste the flesh of a saint.”

“Uh, well, actually, I became a vegan while I was sealed. Eating human flesh is impossible for me.”

Absolutely impossible.

Especially when it comes to physically eating Elsia, who looks utterly devastated by the world. It’s just not doable.

But now I have a problem.

Even if I don’t eat Elsia, leaving her with the Demon King army, which is full of people who would definitely eat a human, would be disastrous.

Keeping her by my side would be the safest option, but it would be a hassle.

Maybe if I treated her like a pet?

…No, that wouldn’t work. I can’t do something that weird.

“…Balzac, remember that item I brought back from the dungeon?”

“Do you mean, that item?”

“Yes, that one. I plan to use it on this saintess.”

The surrounding demons started to buzz.

Balzac brought me the magical item I had tossed into the treasury.

At first glance, it looked like an ordinary stone.

But to those who knew, it was clear it held immense magical power.

“My Lord, what is that item?”

“This is a Rebirth Stone. It can transform someone into any race they desire.”

In the game’s school arc, the villainess who bullied Elsia tried to use this to turn her into a dog.

Well, that plan was foiled by one of the love interests, but… By chance, I got my hands on the same item, so I’ll use it.

There are several Rebirth Stones, so for now, I’ll use one to transform Elsia into a suitable race to protect her.

“W-What! Then, are you planning to welcome this saintess as one of us?”

“Yes.”

“T-That means she has earned my Liege’s favor, correct?”

“Huh? Well, yes.”

“Oh, ohhh! You heard that, everyone! Let’s get to work immediately!”

Balzac’s glasses gleamed as he enthusiastically started giving orders to his subordinates.

I answered offhandedly, but what did he mean?

Well, whatever. 

Let’s quickly change Elsia’s race.

“…You’re…not going to kill me…?”

When I approached Elsia with the Rebirth Stone, she looked up at me with lifeless eyes.

I nodded.

“That’s right. Do you have any requests? I’ll transform you into whatever you desire.”

“…Desire…?”

“Isn’t there something you want? Like a stronger body, or something else?”

“…I…”

In a barely audible voice, Elsia said,

“I want to become strong enough to take revenge on those who raised me up as a saintess without my consent, only to call me a witch when they realized I couldn’t defeat the Demon King.”

“I see. Well, how about a vampire?”

“I leave it…to you…”

I used the Rebirth Stone to transform Elsia from a human into a vampire.

Vampires are a race with power equal to or greater than that of the demon race that perished centuries ago. 

They have weaknesses like sunlight, silver, and holy water, but at night, they can even surpass demons.

I think it’s a race that aligns with Elsia’s wishes.

But still…

The storyline seems to be deviating quite a bit. Is this okay?
