A blood-red crescent moon hung in the night.

A white negligee laid on the floor, torn. A slender, ***** figure was bathed in the red moonlight pouring through the large windows.

Yulia struggled in front of the window, pushing with all her might. But no matter how hard she pushed, it wouldn’t open, and a black shadow was slowly approaching her.

“No… Please….no…”

Hearing her pleas, red eyes swept across Yulia’s exposed body.

From her smooth, round shoulders, full breasts, and pink nipples to her narrow waist and the hidden area between her legs, already damp with her arousal. The demon’s gaze flitted across her body like a soft touch.

Only then did Yulia realize it was hopeless. It didn’t matter how much she begged. The shadow that closed in was Bael, the merciless king of demons. Tears fell down her cheeks in despair.

“When will you realize?”

The demon approached her as she sat on the floor, his wings spread. Yulia was caught in fear and faltered, but there was no place left to retreat. A strong force tightly gripped her hair.

“You will never escape my clutches. Even if you died.”

She couldn’t help it as a soft sob escaped her lips.

“This finger, this hair– everything is mine.”

Bael’s long, thick fingers went straight between her legs. Her entrance was wet and easily welcomed the sudden intruder. Lewd squelching sounds rang through the night.

“Ah, ah!”

“You love this.”

Yulia’s body shook in time to the rhythm of his fingers. The thrusts seem to hint at what was to come later. Whenever his thick fingers rubbed against her inner wall, her stomach would throb with heat. She bit her lips desperately to stifle her cries.

“Ah, nngh!”

“Hnn, you’re so wet. I think I can fit a couple more.”

Before she knew it, she was being stretched wide by four thick fingers. Bael’s fingers were drenched with her clear fluids that were also dripping down her thighs. What an enticing sight.

Bael pulled his hand away and rubbed her juices on his swollen member. It was thick as a forearm with heavy veins running along the length.

His ***** probed along her slit, seeking entrance. Yulia struggled fearfully.

“If you obey me, I will give you pleasure you’ve never experienced before.”

“No, no, no! Don’t! “

“It’s too late.”

Bael’s mouth twisted at her response. He gripped her knees tightly, one in each hand, and spread her legs apart. Her thighs fell wide open without a chance to resist. Her glistening vagina twitched obscenely, as if in search of something to swallow.

Bael’s brow knit as the head of his cock got caught in the crevice he had been searching for. He adjusted himself briefly before plunging straight in.

“Ah, ah, ah!

Her breath caught in her throat with each ******. Yulia was engulfed in pleasure. She could barely breathe. She cried out as she tightened around him. Bael tilted his head back, savoring the warmth that surrounded his shaft. Pure, high-quality mana filled his body.

The Devil’s Night was just beginning.

* * *

The war against the humans was in full swing. Footsteps echoed in the grand but desolate hall. Piercing eyes slowly moved toward the source of the sound.

The person who broke the silence of the hall was Grand Duke Agares. He calmly ascended the stairs of the throne and knelt down on one knee, not paying any mind to the numerous gazes on him.

“My Lord, I’ve finally found it.”

The air, which had been growing indolent, suddenly changed from the words of the Grand Duke. A number of eyes stopped blinking and stared at him. Agares raised his head and eloquently said,

“Esther Vesdra, the noblest human and also the princess of the humans. She is the key to turn the Lord into the Devil.”

“…….”

“If you allow me, I’ll bring the key right away.”

Agares conveniently omitted the part, “And turn Abeldissim, the capital of humans, into ruins.” Barbatos, the chancellor, noticed it, and stepped in on the king’s behalf.

“Do you think that will work? Not long ago, a new swordmaster blossomed on the human side.”

“If we kill them all, there will be no issue.”

“Think about the future.”

“I don’t know what that is.”

Agares gazed at Barbatos with obvious hostility. He was commissioned by the Demon King to command the military and lead the troops on the front line. Barbatos’ attitude, which seemed to favor the enemy, was unacceptable.

Barbatos, on the other hand, was frustrated with Agares’ way of thinking. The long war between the demons and humans had devastated the human race. Of course, these hardships could not so easily produce an important human being who would later become the emperor.

Although human beings were weaker than the lowest of beasts, their numbers far exceeded that of the demon race. Barbatos judged that it was time to end this useless war. He spoke bluntly to the king,

“My Lord, since the tides of war are starting to turn against us, why don’t you show mercy to our kin?”

“…….”

“Berid is good at human relations, so send him into the lion’s den. If you just request the princess from Vesdra, they will see our sincerity and agree to end the war.

On the throne sat a man with his chin resting in his hand, his posture a bit languid. He opened his eyes slowly. Red eyes glowed through his long black hair.

Even though it was a simple act, a powerful mana wave traveled through the grand hall. Agares and Barbatos realized the king was not in a good mood and hurriedly turned away. At the same time, the demon rose from the throne. Robes of the finest fabric draped his sculpted figure.

“So the key was born to the royal family of Vesdra. Interesting.”

Snake-like pupils slowly swept through the wide hall. The demons who received the king’s gaze all raised their heads in unison. A heavy pressure dominated them. The inevitable instinctive fear crushed down on their shoulders.

This was the power of the demon king Bael.. With his unprecedentedly powerful mana, he unified the underworld and now ruled from his throne.

With each step he took, the absolute power of the king became more and more evident. It was so pure and overwhelming that nothing could compare. In the end, 720 people were unable to withstand the pressure and passed out.

“By all means, bring me the Spirit Stone key. That woman is mine.”

Bael spread his impressive wings, not caring for the other demons’ response. In the end, he only had eyes for the spirit stone, the power of the devil. His mana flashed dangerously purple, as if responding to high-quality mana.

“It had better be real this time. If you let me down again…”

“I’ll keep that in mind, my Lord.”

Agares and Barbatos answered without delay, and the corners of the king’s mouth twisted upward upon hearing it. Standing on the vast terrace, Bael leapt into the air and flew away.

Looking towards the king, who grew farther away under the red moon of hell, the two demons exchanged gazes.

“Okay, send in Verid or Nabal first… I would like to live a long life.” (Agares)

“We also have to proceed with the truce talks.”

“……Damn it.”

Grand Duke Agares cursed with a dissatisfied expression. The arrogant humans still had an enormous debt to repay, but they could not disobey the king’s wishes.

Barbatos blankly answered Agares by summoning the page and sending a message to Verid.

* * *

The people’s cheers rang out in Abeldissim, the capital of the Vesdra Empire. The horde of evil demons finally withdrew from the land of the humans and peace was achieved. It was the first peace in 30 years since the Inma War broke out.

As news spread that the expeditionary troops would soon return, hope returned to the faces of the populace, who were tired of the long war. Those who were mobilized to join the bloody battlefield were parents, brothers, or children. Everyone was anxiously awaiting the return of the expeditionary forces after watching them go off to war.

Those who were ahead of the current trend of events also predicted what would happen much later. The enormous amount of supplies that had been dedicated to the front lines would soon return for domestic consumption, and commercial trade between countries would also resume. Competition was fierce to finish preparations ahead of others and gain a market advantage.

Everyone soon started to dream of their own futures. They seem to have forgotten the existence of the one that actually brought them this hope.

—–

A thin figure stood at the edge of a towering cliff.

With her hands tied, she struggled away from the boiling lava that spewed acrid steam down below. However, the more she resisted, the further the knights with spears pushed her towards the ledge.

“Come on, jump in!”

“Jump in? But this is lava.… !”

“It’s for the peace of the Empire. You must understand! If you continue to resist, we will have no choice but to force you.”

Her delicate body had already been marred by numerous injuries. While being dragged to the border, she resisted and tried to flee.

In front of her stood the imperial knights, sworn to follow the current Emperor, Ingrem V, and the First Empress, Ethel. Behind her flowed boiling lava throwing off extreme heat. Fear could be seen in her large eyes as they flitted between the two sides.

The siege of spears gradually moved closer as the knights closed in. She searched their faces, but couldn’t find a trace of guilt. It seemed like they were simply throwing away unnecessary garbage, not a human being.

With that, she finally lost her last bit of hope and closed her eyes. Her body was roughly pushed off the cliff, and she fell.

I’ve fallen into the Devil’s Castle.

It’s been a little over four years since Yulia was brought into the world of the 19+ rated reverse harem game, [Devil’s Paradise].

The game begins on the 18th birthday of the main character, Esther. A demon visits the emperor and makes a proposal after Esther returns to the inner palace following her birthday celebration.

‘Give her to our Lord and we’ll end this war.’

The demon king’s goal was to become the Devil by absorbing the immense power for the Spirit Stone. However, after repeated failures, he hears a prophecy that the seal of the Spirit Stone can be completely lifted if the noblest human is used as a medium.

Therefore, the demons demanded that Esther, the most noble and well-known princess of the humans, be the “key to the Spirit Stone.”

At first, the emperor refused the absurd demand. However, the favor of war gradually turned against the human side, and, in the end, Esther sacrificed herself to hell.

After she opened her eyes to physical pleasure by performing various deeds with the handsome demons of the underworld, it was as if she were doing her best in the name of the game being a “19+ rated reverse harem.” Well, I remember that the story roughly went like that.

‘It was a game that my senior at work forced me to play, so I don’t remember it clearly.’

When I first opened my eyes, I was really confused. I thought I was dead, but I couldn’t believe, while retaining common sense, that this was the world of a game. That I was the second princess, Yulia, who was not in the original storyline.

For the first few months, I wondered if I was dreaming. Perhaps I was actually in a coma because I failed to successfully take my own life. And since then, my body has been lying in a hospital, and my mind created this strange world.

However, life here was too similar to my miserable reality for this to be dismissed as a dream.

This was the room of the Princess Yulia, where dust bunnies rolled randomly on the floor, long spider webs covered every corner of the ceiling, and a musty smell clung to the air.

How long had she been neglected? Her arms and legs, which should have been fully grown by now, were thin, and her skin, which had not seen the sun, was paler than snow.

Maids often came in without knocking to deliver their messages, which were never good.

Some said, “Don’t come out of the room because there are noble guests in the palace,” or “It is the anniversary of the late Empress, so refrain from acting rashly,” or even “Fast for three days because his Majesty is angry.” Afterwards, I really wouldn’t get anything. The treatment was so cruel that it reminded me of my difficult past.

Nevertheless, when I finally decided to live in this world because I couldn’t find a way out of the game, the first thought that selfishly came to mind was the fact that I wasn’t Esther.

‘I’m definitely going to get out of the palace. I’ll run away to a foreign country and live quietly and peacefully. So let’s just hang in there a little longer. It’ll be okay… ‘

Esther, the emperor’s daughter, who was loved by everyone, is taken to the underworld upon her 18th birthday. The imperial palace, and even the entire empire, is turned upside down due to the unexpected tragedy. In other words, that is the best time to escape.

It is the only chance to run away from these cruel people. These cruel people who keep me locked up perpetually to prevent a stain on the imperial family.

It’s not like I have a personal grudge against Esther, but I can’t do anything. Or so I thought. But the emperor had a different idea.

“You will go to the underworld. I can’t possibly let Esther go.”

“But what the demons asked for is the noblest human being, so how can I…….”

“Yes, Esther is the noblest child. She’s different from you, who eats like a pig and constantly causes trouble. So now, do what you’ve been raised for. Or do you want to be thrown out *****?”

Yulia had no choice but to nod when the emperor told her to pretend to be Esther and risk her life to seduce the demon king.

With Yulia’s nod, the Emperor’s eyes were filled with relief at having dealt with such a bothersome task. Esther didn’t even look her way, ignoring her as if she were a lowly ant.

“But I just can’t believe that it’s going to be like this…”

As she woke up from reminiscing while watching the full red moon that was soaring right above her head, Julia cautiously rose from her bed.

She slightly groaned from all that vertigo before rolling up the sheets abruptly and looked downwards to her arms and legs. They were still quite brittle and pale, but fortunately, no visible wounds could be found.

She had thrown herself into the boiling pit of sulphur blaze. To be precise, she was mercilessly shoved by those spears.

The feeling of being hurled from a high place, the sound of wind gusting in her ears and the blistering heat that had swallowed her whole body were still extremely vivid.

She somehow knew that she would end up being fine inside her head as it had been the same way to how Estelle herself had travelled to the underworld within the game, but when she had truly awakened, she could do nothing other than trembling in fear while losing her mind.

When she looked over her body, she began to feel curious about her current situation. As she peered around carefully, the first thing she could see was a stone wall—cold and gray.

‘A familiar background……’

It was the background that she had seen in a CG within that game. Although the size of the room was rather spacious, it had an unenclosed atmosphere without any sense of brimming life—just as if only the necessities were left behind. The floor was all covered with hides from an unknown creature, and the air that brushed against her lungs was just cold and terrifying.

There was a thick chain hanging by the bedside, which she decided instantly not to think about its purpose at all.

‘I’ve really arrived at the Demon Realm. Originally, this is where Estelle should be brought to, but now, I’m the one who’s here.’

The first thing that she had thought about was what to do if she were to be found out, and whether the fact that she would be killed right away. What the demons had demanded was ‘the noblest human being’, but she was not even a noble person—merely a useless human who had been living her whole life by getting fingers pointed at her.

Her anxious eyes slowly turned to the dark night sky beyond the terrace window. A large, bloody full moon was dyeing the entire Demon Realm in red. Amidst the gloomy atmosphere that was completely different from the perpetually gleaming Vestra Imperial Palace, a chilling energy instantly ran up her spine.

“I don’t want to die like this. What do I do now?”

Julia lowered her eyelids helplessly while burying her head into her raised knees. Her heart prickled, but she only bit her lower lip quietly in patience—all alone.

‘Do I have to pretend to be Estelle in order to live or ……’

Even her corpse would never be left intact when they found out that it was not her at all. Even Estelle, the real key to the Magic Stone, had suffered all kinds of horrific things from those demons before she finally broke down.

When she was merely sighing softly due to her bleak future, the surroundings eventually became noisy for some reason. A number of footsteps began getting closer and closer, while an extremely light voice could be heard intermittently.

“You already got the key that you’ve been waiting for after so long, so why don’t you just send it over to the tower right away? We need to unseal the Magic Stone as soon as possible!”

“It’s not that simple.”

“Does the door even open by itself just by looking at it? Anyway, Brother’s frustration is just too much.”

“If you happen to fail, you will instantly lose the Magic Stone and the key as well. So, will your Master be very pleased with that?”

A cold voice suddenly stopped right in front of the door. As soon as Julia took a breath while she had been listening without realizing it, the door slammed open.

The gazes of those two demons who were standing side by side had met hers directly, while she was desperately clutching the bedsheets like a lifeline. Julia lowered her gaze, but she saw that the men had entered even faster.

‘Really. It really is a demon……’

With long slit pupils like a cat, extremely sharp fangs, a pair of black wings on their backs and above all, those familiar faces—even though she was seeing them for the first time, Julia had immediately recognized their identities.

The slurred voice and the slightly droopy corners of the eyes were evidently similar to the appearance of the demon, ‘Lerazier’ within the game. Although he looked just like a beautiful young man, he was actually the 14th highest demon in the Demon Realm, as he ruled over love and pleasure.

The other one was his twin brother, the 8th highest demon in the demon world, ‘Barbatos’. At a first glance, it was easy to see him as a mere scholar, but his hands were actually quite cruel and brutal as he was in charge of despair, cruelty and ruthlessness.

‘It’s exactly the same as the game’s prologue.’

In the original story, they had dragged Estelle directly in front of the Demon God’s Crystal Ball in the tower. But perhaps things wouldn’t be just as fun if they had been going well from the beginning, so she collapsed under the mighty power of the Magic Stone before wandering through death for a very long time.

‘Estelle, the main character, had suffered the same exact way, but I, who was never in the original, would definitely die.’

There was no interest towards the peace of the human world or anything like which Emperor Ingrem V had spoken of before. She just wanted to live. Even if it was just once, no, she terribly wanted only one day, for her to live a normal life just like everyone else.

Her hands trembled as she grabbed onto the unfamiliar sheets.

“Does the key look strange?”

“She must have been scared. Humans are weak, after all.”

“Still, are they usually this frail? It’s even smaller than the wolf I raise.”

“There is no other human being that could be bigger than that. Stop being stupid.”

Julia carefully looked up at the two of them, who were casually having a conversation.

In the original story, Estelle was very proud of herself. So, when she first met the two of them, she acted bravely and vainly right until the very end. Her appearance was already enough to pique the demons’ twisted interest.

But Julia simply didn’t have such audacity. She had just turned to stone in fear of when they would actually kill her. In fact, she had no idea what to do at all.

Then, her eyes met with Lerazier’s all of a sudden.

“…!”

As she bowed her head in surprise, there was an abrupt popping sound over her head as the wind gusted.

“What, she’s actually cuter than I thought? Since she’s such a great princess, I was really looking forward to how we would break her spirit.”

Lerazier strode along before grabbing the sheet that she had been holding onto like a lifeline with one of her hands and lifted it away. Julia tried her best to not let it get taken away, but she just could not win against the power of a demon. In fact, her slender and fragile body wouldn’t have been able to withstand the power of anyone, not to mention a demon as well.

A long shadow loomed over her head as she stumbled right onto the bed. It was Barbatos, the one who had been silent all this while.

“There’s nothing more to see here. Let’s just take her to the tower.”

“What? You just shouted how it wasn’t a simple problem at all, didn’t you?”

“No matter how hard you look at it, isn’t it quite strange?”

Barbatos took out a handkerchief and grabbed Julia’s chin as if he just didn’t want to touch any insignificant humans directly. A pair of thin, snake-like eyes had ripped apart her whole appearance.

“The appearance is roughly the same, but this attitude—it’s not that of a princess. She is a human being who has been accustomed to submission.”

“Are you implying that she’s a substitute? But there’s no doubt that pinkish platinum hair is the symbol of Vestra’s Imperial Family!”

Lerazier, who had grabbed Julia from his brother, began to look closely at her face once again. Her hair that was as pale as an unripe fruit had been messed up in his hands.

As her cheeks moved to and fro between the two brothers, a firm conviction eventually settled in Julia’s mind. And the fact was that if it were to go eventually like this, she would ultimately die with much certainty and clarity—whether she would be swept away by the power of the Magic Stone or end up dead because of the felony that dared to deceive the demons.

If she were to die, she should at least make an effort to live. Julia gathered all her courage before she carefully opened her mouth.

“I—I am a princess…”

As soon as she said it, she regretted it terribly. Her voice was dreadfully trembling, even when she heard of it herself.

Unsurprisingly, Barbatos’ eyes turned even colder over those glasses. Even before Lerazier could say anything, he had opened his mouth first.

“I’ve already said that I didn’t have any time to play around, human.”

“I, I really…”

“If you stand in front of the Magic Stone, everything will be clear instantly. Follow me right away.”

He turned around mercilessly as he gave no room for excuses at all. Even before Julia could grasp the meaning of his last words, Lerazier had grabbed a hold of her lightly with one hand and embraced her. Then, as if he was fond of it, his steps began to trail airily after his brother’s footsteps.

Eventually, he added some words of comfort in his own way.

“If Brother comes out too strong, I can’t really help it either. Instead, I’ll carefully weave your body into a doll, so don’t worry about it too much.”

“A doll…”

“Of course, if there are still any parts being intact though, kekkek!”

To be honest, Julia had an absolutely minuscule amount of courage—she feared turning into a doll much more so than simply dying. She tossed her head forcefully to live while struggling to avoid Lerazier’s touch, which was already holding onto her slender waist.

Although her identity had been questioned, the situation itself was proceeding exactly the same as the game’s prologue.

Estelle, who had finally reached the top floor of the Demon God Tower, was forcibly dragged into a space where the crystal ball had already been sealed by two demons. However, the magical power that was emitted by the magic crystal had been so strong until it could no longer survive as a human body, which had yet to be blossomed into a ‘key’ before she merely fainted while having barely saved her own life.

After that, the full-fledged story finally began, and she had to raise her various stats, but Julia could not possibly think that she would be able to get that far.

It would be sheer luck if she didn’t die while frothing away as soon as she entered the Demon Tower, let alone in front of the crystal ball itself.

‘I don’t want to die……’

Unknowingly, Julia’s hand that was still grabbing onto Lerazier’s hem began trembling. To anyone else, they would have felt pity for her slender figure, but Lerazier even had loosened his own grip against her as if it was such a pleasure to let Julia dangle from the side.

“I’m, I’m going to fall like this!”

“Then, why don’t you hold me a bit tighter? Hang on to me with all your might. I won’t exactly help you even if you were to fall.”

The gigantic wings spread out like countless petals bursting from his back. Barbatos, who was walking ahead of him, suddenly leaped into the air and flew through the dark night sky.

Julia’s fear finally reached its peak when Lerazier leaped over the window sill as well. She clung onto the demon’s neck with all her might, lest she would unknowingly fall onto the distant ground. On top of that, she was only thinking of just one thing.

‘I don’t want to die, I don’t want to die, I don’t want to die!’

She eventually reached the Demon Tower while still hanging from Lerazier’s neck. The two demons had struggled against the pulsating magic power before climbing up the stairs and finally stood in front of the great altar.

By the time she had regained her senses, it was already too late. Right before her eyes was a huge sphere of deep purple that was glowing with a buzzing sound.

Just like her eyes would go blind if she had stared directly into the sun, it was rather difficult for Julia to gaze at it for a long time since it was emitting such a huge wave.

“Oh, Brother…”

“I’m looking at it.”

A slightly confused groan could be heard in Julia’s ears, who was merely standing awkwardly. She slowly shifted her gaze before turning around to look at them, and only then did she realize the situation she was currently in.

‘It’s exactly the same as the CG in the game. This is definitely the Demon God’s crystal ball.’

The entire hall, which was as grand and huge as the stadium, had existed solely for the sake of the magic stone.

It was definitely the same as in her own memories, but a different kind of pressure than back when she had simply looked through the monitor was weighing down against her. As if she was just standing in front of a primeval nature, a boundless state of awe had swallowed up all of Julia’s other sorts of emotions.
