Prologue • The Cold-hearted Demon King Girl? The Passing of the Hero

Ah… damn it…
So this is how I die…

The young man, clad in a dark navy robe and heavy armor, thought to himself.

At this moment, a jet-black slender sword was embedded in his body.

The blade pierced through his chest armor.

Fresh blood slowly flowed from the wound, dripping onto the robe.

A large area was dyed red.

Following the exquisite patterns carved into the sword, one could trace it to its source.

At the hilt was a slender, delicate hand.

The owner of that hand wore no expression at all.

On her cold and stern face, there was not a trace of emotion.

She… was like a killing machine.

The young man stared blankly.

The girl had waist-length jet-black hair.

That dark hair set off her breathtakingly beautiful face.

“If I could have a girlfriend like her, then I could die without regret.”

That was what the young man thought.

So much so that he even forgot the pain.

Forgot that the one standing before him was the guide to hell itself.

The girl was—

The Demon King.

And he… was—

The Hero.

“What are your last words, the eighty-sixth hero?”

The girl asked.

Her voice was calm and completely devoid of emotion.

Yet it was exceptionally pleasant to hear.

Clear and crisp, like the ringing of silver bells.

It came from her lips, soft in volume.

But more than enough for the young man to hear.

“…Hahahahahahaha— cough—”

The young man froze for a moment, then suddenly burst into laughter.

This only worsened his pain, making his face turn even paler.

He couldn’t help but gasp for air.

After a pause, he spoke a sentence the girl had never heard since her birth.

“You’re really beautiful…”

The girl was a little at a loss.

She had killed countless people who called themselves heroes.

Each time, she would provocatively ask for their last words.

What she received were nothing but curses and hatred.

She was long used to it.

But this time, she was surprised.

Someone actually praised her appearance at the moment of death.

What a foolish person.

“Thank you.
Arrogant fellow.”

A faint blush appeared on the girl’s fair face.

“If there’s a next life, please be my girlfriend.”

“Hahahahaha.”

“The way you blush is really cute.”

“So then… goodbye!”

The young man laughed wildly.

After laughing, he reached out and gripped the sword.

With all his strength, he pulled it out.

The sword was easily withdrawn from his body.

The young man collapsed like a puppet with its strings cut.

Blood gushed out like a spring.

That “puppet” lay in a pool of crimson.

And fell asleep.

“An interesting fellow.”

The girl withdrew that trace of shyness.

She casually tossed the sword into the void.

The blade slowly flew into nothingness.

Before long, it vanished without a trace.

The girl stood beside her throne.

Like a lone and proud flower blooming atop a high mountain peak.

She surveyed the battlefield that now held only herself.

Corpses lay everywhere.

Weapons were scattered across the ground.

The girl summoned a flaming hellhound with three heads.

She ordered it to clean up the battlefield.

The massive three-headed hound, as large as an elephant, opened its three enormous mouths.

Its crimson fangs tore and bit.

One by one, it devoured the corpses on the ground.

Before long, it had swallowed all the bodies except for the hero.

The hellhound prepared to devour the hero’s corpse as well.

But it found that it could not.

A force was stopping it.

At the same time, a voice echoed within it.

“Get lost.
You insect.”

The voice was filled with murderous intent.

It allowed no defiance whatsoever.

The hellhound was so frightened that it whimpered and trembled on the ground.

Naturally, the Demon King noticed something was wrong.

She gently stroked the hellhound with one hand.

With the other, she examined the hero’s body.

Her slender fingers lightly touched the hero’s face.

In an instant, the hero’s body was enveloped in blue light.

Pale blue particles surged out from his body.

The particles slowly gathered together.

Then condensed into a faint blue crystal.

The crystal actually floated in midair.

Slowly rotating clockwise.

It was truly astonishing.

So many things had happened in a single day.

Even the girl was having trouble processing it all.

“A soul-power crystal…”

“And such purity.”

The girl spoke softly.

Her lips parted slightly, revealing a surprised expression.

She was in need of this item.

What she intended to do with it, no one knew.

Not even the hellhound understood its master’s intentions.

It looked at the hero’s body, now reverted to its original state without the crystal.

It poked it with its claw.

After confirming nothing was wrong, it opened its mouth wide.

And swallowed the corpse whole.

At the instant it swallowed it, the hellhound suddenly exploded.

What remained was a cocoon.

The girl was shocked by the sight before her.

Even as the Demon King, who had lived for hundreds of years, she had never seen anything so bizarre.

She couldn’t help but press a hand to her forehead.

Just as she was deep in thought, the cocoon suddenly twitched.

Then it cracked open.

Something crawled out from inside.

Upon closer inspection…

It was actually a naked少女.

She had red hair.

Although her face was not as refined as the Demon King’s, the more one looked at her, the cuter she became.

She looked a little dazed.

Most importantly…

She had animal ears on her head.

The Demon King tried touching her head.

The fluffy ears drooped down.

She seemed to enjoy it, letting out soft whimpering sounds.

However, she did not seem able to speak.

She could only make “whimpering” or “woof-woof” sounds.

Her expressions were constantly amusing.

At the very least, the Demon King actually showed a rare smile.

Such a sight was extremely uncommon.

Thus, the eighty-sixth campaign to slay the Demon King ended.

With humanity’s crushing defeat.

The human army was completely wiped out.

The human hero, Allen, fell heroically.

The history books gained several more pages.

…………

From then on, the Demon King began living a shameless life.

Just kidding.

Hello everyone.

This is sh.

Recently, I’ve seen many people writing this kind of gender-change story.

So I decided to follow the trend as well.

But I thought, following the trend doesn’t mean copying it completely.

You can’t just tell me to write and expect me to do it blindly.

At the very least, I have to try something myself.

So—

I plan to write a story with a slight tendency toward master abuse.

But don’t worry.

Later on, the story will return to normal.

That’s all.

Let me say this quietly.

If you like it, please add it to your favorites.

And I’m still asking for monthly tickets.
