The last thing Akira remembered was the blissful crescendo of digital ecstasy, a pantheon of pixelated idols smiling down on his fervent… dedication. He’d been on his twelfth session, a personal record fueled by a potent cocktail of lukewarm instant ramen and sheer willpower, when the screen had fractured in a blinding white light, followed by a sensation akin to being compressed into a digital black hole. He’d assumed it was the ultimate “technobreak,” a legendary demise whispered in the darker corners of online forums. He hadn’t expected an encore.

The first sensation wasn't pain, nor the cold digital void he’d imagined. It was a profound, all-encompassing thirst. Not the nagging dryness of a parched throat, but a primal, animalistic craving that resonated deep within his very being. He blinked, his eyelids feeling strangely light, and found himself staring up at the rough-hewn ceiling of what felt like a stone coffin.

Where… am I?

Panic flickered, quickly followed by a bizarre sense of… clarity. His senses were hyper-acute. The musty smell of damp earth and something else, something metallic and vaguely sweet, filled his nostrils. He could hear the faintest rustling sounds beyond the thick stone. His skin tingled with an unfamiliar energy.

Then, a voice echoed in his mind, resonant and authoritative, yet undeniably internal. "Welcome, Lord Vesperus. You have been chosen. I am The Vampire Kingdom System. My goal is to guide you in recreating an entire kingdom of vampires, with you as its supreme King."

A translucent blue screen flickered into existence before his eyes, displaying information he somehow instinctively understood.

Below his stats was a small, rudimentary map showing only the cramped space he was in, and a flashing notification:

Main Quest: First Awakening

Vampire? Akira’s (or rather, Vesperus’s) mind reeled. Reincarnation was one thing, a staple of countless manga and light novels he’d devoured in his past life. But a vampire? And a "progenitor" at that?

He pushed against the heavy stone lid above him. To his surprise, it moved with minimal effort, groaning as it slid aside, revealing a sliver of pale moonlight filtering into the darkness. He levered himself up, his body feeling strangely powerful and agile, a far cry from his former sedentary existence.

Stepping out of the sarcophagus, he found himself in a large, circular chamber filled with rows upon rows of identical stone coffins. Dust motes danced in the moonlight that streamed in from an archway at the far end. The air was cold, but it didn't bother him. In fact, there was a strange invigorating quality to it.

He instinctively knew certain things. Sunlight wouldn't burn him. Garlic held no threat. Stakes through the heart? A ridiculous notion. His first wish, granted upon his bizarre reincarnation, had seen to that. A wave of giddy power washed over him. He was free from the shackles of vampire lore.

Then, his second wish made its presence known. A subtle, insistent warmth pulsed in his lower regions. Curiosity overriding his initial apprehension, Vesperus glanced down. His eyes widened. Even in the dim moonlight, the difference was… substantial. Ten inches. He, the perpetually virgin Akira, was now… undeniably well-endowed. A blush, a phantom echo of his past awkwardness, flickered across his cheeks before being overtaken by a strange sense of… potential. The System's purpose – building a kingdom, a harem – suddenly felt a lot less abstract.

The gnawing thirst returned, stronger now. It was a deep, visceral need. He knew, with the same instinctive certainty that told him sunlight wouldn't harm him, that he needed blood. Fresh, vital blood.

The archway beckoned. The Map on his interface pulsed, showing a slightly wider area beyond. He could hear faint sounds now – the chirping of unseen insects, the rustle of leaves, the distant hoot of an owl. A whole new world lay beyond this crypt. A world ripe for… the rise of Lord Vesperus and his Vampire Kingdom.

Taking a deep breath, the metallic tang in the air growing more alluring, Lord Vesperus, the reincarnated vampire progenitor with a ten-inch surprise, took his first step towards his destiny. The moonlight bathed his face, revealing not fear, but a dawning sense of anticipation.

Alright, System, he thought, a flicker of his old otaku enthusiasm mixed with a newfound predatory hunger. Let's build this kingdom. And this harem.

He strode towards the archway, the ancient stones echoing softly beneath his surprisingly silent steps, ready to embrace his crimson future.

The stone lid scraped against rock, the sound immense in the silence of the crypt. Vesperus pushed it aside, his new body moving with an effortless power that made his previous forty years of life feel like a distant, feeble dream. Moonlight, fractured by a dense canopy of ancient trees, filtered down, painting the forest floor in shifting patterns of silver and shadow.

He was in an old-growth forest, the air thick with the scent of damp earth, rich loam, and something else – something wild and alive, carried on the cool night breeze. His new senses were a roaring symphony; every rustle of leaves, every distant hoot, every faint scent amplified beyond anything he’d ever known. It was exhilarating, almost overwhelming.

But above all, there was the thirst. It was a savage, aching void in his chest, demanding to be filled. His fangs, a subtle pressure behind his gums, throbbed with an unfamiliar readiness. The System had announced his quest completion – First Awakening – and the rewards of 50 Stat Points and unlocked abilities. He could feel the latent power. But the thirst was immediate. It commanded him.

He moved through the trees, a silent wraith. His vision cut through the gloom, distinguishing every root and fallen branch. He flowed rather than walked, his heightened senses guiding him towards the source of the faint, vibrant scent of life that promised relief. It wasn't human, not yet, but it pulsed with vitality.

He found it quickly – a wild boar, massive and oblivious, rooting around near a cluster of bushes. For a fleeting second, the image of his old life, of convenience store meals and virtual fantasies, clashed with the raw, primal reality before him. But the thought was a wisp, immediately consumed by the hunger. This was food. A necessity.

He launched himself forward. The boar let out a startled squeal, but it was too late. Vesperus was on it in a flash, his new strength pinning the beast instantly. There was no hesitation, no moral qualm. Only the consuming need. He sank his fangs into its neck.

A jolt, electric and profoundly satisfying, surged through him as hot, rich blood flooded his mouth. It was an explosion of flavor, power, and pure, unadulterated relief. The thirst receded, replaced by a deep, invigorating warmth that spread through every fiber of his being. He drank until the boar lay still, utterly drained.

He pulled away, a thin streak of crimson marking his chin. A shiver ran through him, not of disgust, but of primal satisfaction. This was what he was now. A vampire. A predator. And it felt... natural. Powerful.

His thoughts cleared, the System’s notifications popping up. Blood Sense. Lesser Regeneration. Good. More tools. He opened his Status Panel and saw the 50 unallocated points. He needed to be strong, cunning, and charismatic. He needed to build.

He quickly allocated the points: Strength and Agility for immediate survival and combat, Endurance to last through any fight, and Charisma. Charisma, to draw others to him, to build his harem, the very fuel for his power, thanks to the System. He felt another surge of raw potential.

His gaze swept the forest. He was the last vampire, immune to the sun, the progenitor of a new lineage. He needed followers. He needed a kingdom. And the System's map, now clearer, showed a cluster of lights in the distance – a settlement.

A predatory smile touched his lips. Alright, world, he thought, a familiar blend of otaku enthusiasm and newfound dark ambition. Let’s see what kind of women you have. And how many points they’ll give me.

He moved deeper into the night, his steps silent, his enhanced senses already sifting through the myriad sounds of the forest, homing in on the distant hum of human life. The night was his. And his empire was just beginning.

The cluster of lights on the System’s map resolved into the faint glow of hearth fires. Vesperus moved out of the dense forest, the ancient trees giving way to a more managed landscape. The air, no longer heavy with damp earth and wild game, carried the distinct scent of woodsmoke, livestock, and, most potently, humanity. It was a different kind of allure than the boar's primal vitality—more complex, more refined.

He stopped at the edge of a field, stalks of some unknown grain rustling softly in the cool night breeze. Before him lay a small, unremarkable farming village. A handful of timber and wattle-and-daub cottages huddled together, a few faint lamps casting weak pools of yellow light from their windows. Dogs barked lazily in the distance, a sound his enhanced hearing translated as bored rather than alarmed. This wasn't a place of power or great riches, but it was brimming with life. And lives were exactly what he needed.

His 80% Rimuru-esque pragmatism assessed the situation: a small, isolated settlement meant fewer guards, less organized resistance. A perfect proving ground. But the 20% Redo of Healer ruthlessness hummed beneath, whispering of the vulnerabilities of these soft creatures, of how easily they could be broken, then remade. The Charisma he’d pumped stat points into felt like a tangible hum under his skin, a magnetic pull he was eager to test.

He approached stealthily, moving between the narrow lanes of the village. The houses were dark now, their inhabitants asleep. He could hear their breathing, the steady thrum of their heartbeats—each one a potential meal, a potential subject. The thirst, having been sated by the boar, was now a quiet purr, a satisfied hunger that gave him clarity rather than desperation. He could afford to be discerning.

A single cottage, set slightly apart from the others, caught his attention. Through a crack in its wooden shutters, a faint, flickering light emanated, and with it, the distinct, steady pulse of a single human heart. A woman’s. The scent was richer here, laced with something soft and vulnerable.

He moved to the window, peering through the gap. Inside, a young woman sat hunched over a crude wooden table, a small oil lamp casting dancing shadows on her face. Her hair, a simple brown braid, was beginning to unravel, and her eyes were red-rimmed. She was stitching a tear in a worn tunic, a pile of mending beside her. She looked tired, perhaps worried. Alone.

Lord Vesperus felt a strange pull. It wasn't just the hunger. His Redo of Healer side saw an opportunity—a solitary figure, potentially desperate, easy to manipulate. His Rimuru side, however, felt a flicker of something akin to curiosity, perhaps even a nascent desire to understand this world's inhabitants beyond their blood. And, of course, the System reminded him of his overriding goal: recreation.

He could burst in, take what he wanted. But that wasn’t his style now. Not fully. The System rewarded willing participation, even if that willingness was influenced by his formidable Charisma or the inherent allure of his vampiric nature. And he preferred to begin his kingdom not with screams, but with awe, or at least, confused surrender.

He melted back from the window, moving to the cottage door. He didn't bother with the latch; his newly acquired Strength easily parted the simple wooden planks with a soft groan that was just loud enough to be heard within.

The young woman looked up, her needle poised. Her eyes, wide with surprise, fixed on his silhouette in the doorway, framed by the faint moonlight. She was pretty, in a rustic, unadorned way. Fear flickered in her gaze, but also a flicker of something else, something uncertain.

Vesperus stepped inside, letting the door fall back into place with a soft thud. He let his presence fill the small room. His Charisma, supercharged by the System points, pulsed outwards, an invisible wave of compelling power. The air seemed to thicken, the flickering lamplight softening the sharp edges of the room, making him seem less like an intruder and more like a mysterious, inevitable force.

"Forgive my intrusion," he said, his voice a low, melodic rumble, far from the reedy tones of his past life. It was a voice designed to soothe, to enchant, to disarm. "I am... a traveler, lost in the night."

The woman stared, mesmerized. Her needle dropped from her fingers, clattering softly on the table. She seemed unable to move, held captive by his gaze. Her fear was still there, but it was being slowly, inexorably, overlaid with a strange fascination, an inexplicable trust.

His internal monologue noted the effect of his Charisma. It was even more potent than he'd imagined. This was going to be easy. And potentially, very enjoyable.

He took a slow step closer, then another, his gaze never leaving hers. He could hear her heart picking up pace, a frantic drum against his ears. Not just fear now, but anticipation. Desire. He could practically taste the sudden surge of adrenaline in her blood. This was the moment. The start of his kingdom. And the start of his harem.
