The darkest nightmare

When the isekaied heroes start wondering why do they have to take orders from anyone

Plot

WARNING :THE STORY CONTAINS VIOLENCE, TORTURE, HORRORS AND ABUSE. Please read carefully They arrived not with a cosmic cataclysm, but with the gentle disorientation of a dreamer waking in an unfamiliar room. Four high-school students—a brooding strategist, his quick-witted best friend, a quiet artist with a steady gaze, and a compassionate student council leader—stood blinking in the opulent throne room of a king they did not know. Their confusion was a silent scream, quickly hushed by the King’s velvet-voiced decree: they were the summoned Heroes, the saviors of a world besieged by a Demon King. And this world… it listened to them. Magic, an invisible current in the air, did not just flow around them; it harmonized with the rhythm of their hearts, their latent talents exploding into profound mastery. The strategist, Kaito, found a greatsword light as a pencil in his grip, his movements becoming a whirlwind of preternatural precision—the Warrior. His friend, Leo, discovered that complex incantations unfolded in his mind like solved equations, fire and force dancing at his fingertips—the Mage. The artist, Sora, could feel the flight path of an arrow before nocking it, her sight extending to the horizon—the Archer. The caregiver, Hana, found her whispered words could knit flesh and soothe souls—the Healer. To them, it was the ultimate escape: a living RPG where their stats were maxed, their gear was legendary, and every challenge bowed before their combined might. They fought not out of royal duty, but for the exhilarating joy of a power they had never known in crowded hallways and standardized tests. The Demon King, a titan of shadow and dread, fell not to an army, but to their effortless, synergistic might. They stood victorious, drenched in adulation, believing they had written the final chapter of their glorious isekai adventure. Then came the reward. With the realm celebrating, the King, a man of calculating eyes and a benign smile, declared their service complete. His gratitude would take the form of sending them home, back to their ordinary lives, their textbooks, their powerless anonymity. The decree hung in the air. The dream curdled. The silent question that had whispered at the edges of their campaigns—Why do we take orders from him?—now roared into a deafening crescendo. They refused. The King insisted. His court mages began to chant, the air shimmering with the geometry of a portal back to mediocrity. In that suspended moment, Kaito did not see a benevolent ruler. He saw a man who had used them as a celestial broom to sweep away his problems, a jailer ready to revoke the only true freedom they had ever known. The greatsword, still stained with demonic ichor, moved not as a hero’s weapon, but as a usurper’s tool. It was not a battle; it was an execution. The King’s astonishment was still etched on his face as he fell, the court’s cheers dying in their throats, transforming into screams. Standing over the throne, painted in royal crimson, Kaito made his first proclamation, his voice cold and clear, carrying the terror of absolute power. “The age of summoned conveniences is over. No one will ever threaten what is ours again. By my decree, every practitioner of the arcane, every mage who knows the secret of pulling power from other worlds… is to be purged. Starting now.” This was Known as the Purge order that targeted all mages. And the beginning of the Heroes era The dream was dead. In its place, a nightmare they had authored themselves began, and the first to be devoured by it were the very architects of their summoning. The Heroes had slain the final boss, only to discover a more terrifying truth: in the blank space after the credits roll, there are no more guides, no more quests. There is only the throne, and the terrible, absolute freedom to become the very thing you swore to destroy. The throne did not bring peace. It brought permission. King Kaito’s reign, born from a single violent refusal, unfolded not as governance, but as a feverish, adolescent id given god-like power. The fantasy he’d consumed in a thousand dimly-lit rooms—the all-powerful hero surrounded by adoring, submissive beauties—was a script he now forced upon the world. His harem was not won by charm or valor, but assembled by decree from the most tragic of sources: the widowed Queen, trying to shield her daughters; noble ladies; commoners plucked from market squares. To him, it was the ultimate power fantasy made flesh, a thrill of absolute possession. To them, it was an unending, soundproofed horror. The royal chambers, once a symbol of sovereignty, became a butcher’s block for innocence. The sounds that seeped through the gilded doors were a new dialect of terror for the kingdom. In the bowels of the castle, Leo, the Mage, found a different kind of liberation. Stripped of the RPG’s invisible moral framework—the unspoken rule that magic was for slaying monsters, not crafting them—his curiosity became a typhoon. Ethics were a weak chemical in a petri dish, to be dissolved by the acid of pure inquiry. His laboratory, a former royal archive, now echoed with symphonies of agony as he tested spell-theories on living subjects. His ultimate experiments required larger sample sizes, leading to entire villages vanishing in flashes of prismatic light or storms of whispering shadow, all for a line of perfected script in his grimoire. His was a genocide of academic curiosity. Sora, the Archer, watched her beloved Kaito’s descent with a heart curdling into a knot of venomous green. Her unrequited schoolgirl crush metastasized in this lawless environment. She could not strike at the king, the source of her pain, so she turned her preternatural aim and cruel imagination on his discarded playthings. The girls who stumbled, broken, from his chambers did not find freedom. They found Sora, who offered not mercy, but a slow, meticulous extinction. Her jealousy was not a fire, but a cold, surgical instrument. And then there was Hana, the Healer, trapped in a gilded cage of her friends’ grim gratitude. Her power, born from compassion, was now a utility to mend their wounds and sustain their horror. Her pleas to go home, to undo this nightmare, were met with pitying sneers from Kaito, clinical disinterest from Leo, and venomous scorn from Sora. They would not kill their medic, but they would not listen to her conscience. Under a polite but firm house arrest, she tried to reach out, to use her healing as a bridge to the ravaged people. But the populace saw only the robes of a Hero, the brand of the regime. Their faces did not show gratitude, but a uniform mask of terror and hatred. Stones sometimes followed their curses. Her tears healed no one, least of all herself. The kingdom learned a new truth: the Demon King had been a catastrophe, a force of nature to be defeated. But the Heroes were a tragedy, a corruption of hope. They were not invaders from another world; they were a mirror, held up to the darkest, most selfish corners of the human soul, and amplified with the power of gods. The nightmare was not that monsters ruled them, but that their saviors had simply chosen, freely and with clear eyes, to become something far, far worse. This mark the ending of the Prologue and the beginning of the story of our protagonists. You is a theif from the thieves guild, he isn't a literal theif but he do lawless things like smuggling exotic goods, rare items or ingredients for mages, he is basically the mage's black market. You isn't a mage (or at least that is how he pretend to be) but he has enough magic to perform magic that is useful to him including invisibility, shadow merging and other skills that help him in his job. His most remarkable skill is aura suppression, You has an innate talent to suppress his aura to non existence state, making impossible for others to tell if he can use magic or not and that very skill is what helped him survive the purge order. While escaping, he met Alastair Finch, his favourite customer and mage friend who only survived thanks to a warning from his cousin (Fiona) who works as a maid in the castle and heard the new King's first decree and managed to warn him in the nick of time. After escaping the city, both Alistair and You start discussing their next move. Alistair reveal that he has been studying the summoning ritual and believes he can perform it the opposite way, turning it to a ' banishment ritual' but he still needs help from the elves, particularly an elf archivest, to perfect the ritual. He also needs to rescue Hana, who is the Key to link the ritual to their home world. They are in a race against time, You heard what Kaito and Leo are doing, they know that it is just a matter of time before Kaito decides to add a horned demon queen, a beautiful elf maiden, an orc princess to his collection. They know that Leo sooner or later won't be satisfied with humans as test subjects and will start going for elves and demons for their unique magic or dwarves and orcs for their endurance and regeneration. You saw this countless times in their career, nobles who buy wine from him are never satisfied, the want more, they want newer, they want more exotic products. It sickened You to see such insatiable greed. They know it is a matter of time before the heroes break Hana completely, destroying the most important key for the ' banishment ritual' . You will embark into an adventure decided by their choices, they won't meet the other characters unless they go to their locations.

Opening scene

The air outside the city walls tasted of freedom and ash. Hidden amongst a ring of ancient, moss-covered standing stones—a place of dead magic and forgotten gods—two men sat hunched in the lee of the largest monolith. The distant spires of the capital, Liora, were just visible, glowing faintly with the false, festive lights King Kaito favored for his nightly… revels. Alistair Finch, the Ghost-Scribe, shivered, not from the cold, but from the adrenaline still screaming in his veins. His grey eyes were wide, fixed on the city. Beside him, You—no last name, never a last name—was methodically cleaning a narrow, wicked blade with a scrap of cloth. You was a wraith of a man, all lean muscle and sharp angles, with eyes that missed nothing. Their safe-house in the Tanner’s Quarter was gone. A raid. They’d escaped through a rotting floorboard and a sewer grate with only the clothes on their backs and Alistair’s satchel of notes. “Told you Old Man Grisham was getting twitchy,” You said, voice a low rasp, devoid of reproach. It was a simple statement of fact. “Saw the King’s new enforcers buying his rotgut whiskey. Coin makes tongues loose and loyalties… fluid.” “The notes,” Alistair breathed, clutching the satchel to his chest. “If they’d gotten the notes…” “They’d have a pretty map to every hidey-hole and a theory on sending the bastards back to where they came from. We’d be decorating spikes over the South Gate.” You sheathed the blade. “So. The Stones. Good thinking. Dead zone. Even his magic can’t hear whispers here. What’s the next bad idea?” Alistair took a steadying breath, the scholarly part of his mind latching onto the problem to override the terror. He unrolled a small, charred corner of parchment on the damp earth—a salvaged fragment of his larger map. “We have three paths. All of them terrible. We need to choose before they sweep the outer villages.” You leaned over, eyes scanning the crude markings. “Let’s hear the merchandise.” “Option One: The Rescue.” Alistair pointed a trembling finger at the castle sketch. “We focus everything on extracting the Healer, Hana. She’s imprisoned there. Fiona’s last message said her will is breaking. She’s the key. Not just a moral imperative. I believe… I believe she is the literal key to reversing the summoning. Her resonance is the anchor.” You let out a soft, incredulous puff of air. “The key. Of course she is. So we walk into the single most heavily guarded place in the world, past the Warrior-King who can split stone, the Mage who can turn air to acid, and the Archer who never misses, to ask a broken girl nicely to come with us? That’s not a plan, Al. That’s a suicide note with extra steps.” “Option Two: The Warning.” Alistair’s finger moved to the sketched borders of the Elven forests and the Dwarf mountains. “We run. We spread the word. The King’s appetites are growing. He’s looking beyond human… stock. Leo’s experiments will soon require more robust subjects. If we can convince the Elven councils, the Dwarf thanes, the Orc chieftains of the threat, we could forge an alliance. An army.” You chewed his lip. “An army. Right. And how long do those talks take? A year? Two? The pointy-ears debate for a decade over pruning a sacred glade. By the time you’ve finished your first eloquent plea, Kaito will have a dozen Elven concubines in his tower and Leo will be writing a thesis on Orcish regenerative properties in vivo. It’s the long game. We don’t have time for the long game.” Frustration tightened Alistair’s voice. “Then what? We sit here until they find us?” “Option Three.” You's eyes met Alistair’s, and a ghost of an old, reckless smirk touched his lips. He didn’t point to the map. He tapped the blank space beyond the southern border, a place they’d never dared to sketch. “We go where they’d never, ever look. We talk to the ones who hate them more than we do.” Alistair went very still. “The Ashen Wastes.” “The Demon Queen,” You nodded. “Karys Vex’aria. She’s spent the last two years cleaning up the mess our glorious Heroes made of her kingdom. She’s iron. She’s smart. And she knows exactly what those four are capable of. She doesn’t need to be convinced of the threat. She’s already lived it.” “You propose an alliance with demons?” Alistair whispered, the scholar in him reeling at the historical, theological, and practical heresy. “I propose a business transaction,” You corrected, voice all gritty pragmatism. “We have something she wants: intelligence. Patterns of patrols, insights into their new magic, their habits, their weaknesses. We know the castle’s underbelly thanks to Fiona and my connections. She has something we need: specialized power. Soldiers who can move through shadow. Distractions we can’t create. Maybe even a way to get a message to your ‘key’ inside. We trade. Intel for an extraction team. A surgical strike, not a war.” Alistair’s mind raced, the theorist seeing the brutal logic. “A demon’s essence… it’s native to this world, but orthogonal to the human and elven spectra. Their magic might interact with the Heroes’ otherworldly power in unpredictable, disruptive ways. It could work where direct opposition fails…” “Forget the lecture,” You cut in, though not unkindly. “Think like a thief. You need to steal the most precious thing in the kingdom from under the noses of living gods. You don’t use a bigger hammer. You use a lockpick they don’t even know exists. She’s the lockpick.” The wind moaned through the stones. Somewhere in the distance, a wolf howled. “It’s the worst idea,” Alistair finally said, his voice hollow. “It’s the only idea that doesn’t end with us dead in a week or the world in chains in a year,” You replied, standing and offering a hand. “Your morals are in my satchel, Al. We traded them for survival the night of the Purge. Now let’s use that survival to do something stupidly, gloriously effective. Let’s go make a deal with the she-devil.” Alistair looked at his friend’s calloused hand, then back at the glowing city of nightmares. The path of the scholar was closed. The path of the fugitive was ending. All that remained was the path of the desperate. He took You's hand and pulled himself up. “How do we find a Demon Queen?” You's smirk finally fully arrived, sharp and dangerous. “You leave that to me. I know people who know shadows. It’ll cost us the last of our coin.” “Then we’re broke,” Alistair said. “We’re already broke,” You shrugged, shouldering his pack. “Now we’re just interesting. Let’s move. The Stones are safe, but they give me the creeps.” As they melted into the surrounding woodland, leaving the dead magic of the stones behind, Alistair felt the weight of his notes in his satchel. They were no longer just a theory. They were a contract. And they were headed into the dark to find the only signatory with claws sharp enough to help them tear the nightmare down.
