Valentin's eyes fluttered open, the dim light of a strange dawn filtering through enormous gothic windows. He blinked, disoriented, his senses screaming in confusion. The air smelled faintly of iron and something sweet, almost intoxicating, and as he moved, he realized with a start that his body felt different—stronger, sharper, yet heavier with an unfamiliar tension. He flexed his fingers; they were elongated, nails sharper than human nails, and the skin over his arms was pale, almost luminous.
"Oh… what the—?" Valentin muttered, his voice unfamiliar, deeper, huskier. He stumbled upright, heart racing, and caught sight of himself in a massive mirror leaning against the wall. The reflection staring back was that of a young vampire, a low-ranking one by all appearances: slender, angular, pale as moonlight, but with eyes burning a faint crimson. His chest rose and fell rapidly; the sensation of hunger gnawed at him, sharp and urgent.
He tried to remember what had happened. One moment, he had been walking home from school, the city streets alive and buzzing with neon lights, and the next… a blinding pain, darkness, and now this. Reincarnation, he realized with a stunned clarity, a system of fate far stranger than he had ever imagined. And then the rules began to make themselves painfully obvious. His tongue darted across his fangs, testing the bite, and a sudden craving for blood—sweet, warm—shivered down his spine.
Valentin groaned, clutching his stomach. "Okay… calm down. Think. Don't panic. Just… survive." He tried to stand, only to stumble again. The body was still unfamiliar, sensitive to the slightest touch, as though every nerve had been sharpened to a dangerous edge. He took a cautious step toward the doorway. The hallway beyond was long, adorned with tapestries depicting monsters and creatures of all kinds: lamia, centauresses, harpies, and arachnid women, all standing proudly, poised with magical weapons or curling tails, their eyes seeming to follow him as he moved.
A voice echoed through the hall, light and melodic, yet commanding: "Ah, a new student." Valentin spun, heart leaping. A girl appeared, floating slightly above the ground with faint magical wings, her hair a soft pink that shimmered under the early light. "Welcome to the Monster Academy," she said, eyes flicking over him, a smile curving mischievously over her lips.
"Uh… th-thank you?" Valentin stammered. He felt the blood in his veins pulse faster at the sight of her. She was… more than beautiful. Almost unreal. He realized, with a sinking sense of both awe and fear, that his instincts were already reacting, and not entirely to his advantage.
"I am Moka Akashiya," she continued, drifting closer. "And you… are our newest vampire. Low rank, I assume?" Her eyes glinted knowingly. Valentin swallowed hard, realizing that she already knew far more than he did about his own condition. "Yes… I—I think so," he muttered.
Moka's lips curved into a teasing smile, and with a subtle tilt of her head, she gestured for him to follow. "Come, I will guide you. You need to learn the basics… starting with your hunger." She paused, voice softening with a subtle, almost intimate tone. "You will need to feed. And not just on anything. The blood of others… of girls… it will sustain you, strengthen you… awaken your true potential."
Valentin's stomach flipped. The implications were immediate, shocking, and yet undeniably exciting. "I-I… have to bite them?" His words trembled between panic and curiosity.
"Yes," Moka said simply, eyes flickering with amusement. "But do not worry. They are students, aware of the system. You are not allowed to harm… unless… it is part of the training."
Training. Blood. Girls. Hunger. The words collided in his mind like a storm. He tried to swallow, but instead, his fangs brushed his lower lip, reminding him that survival in this world came at a very intimate cost.
The hallway opened into a vast courtyard where dozens of students practiced combat, magic, and strange hybrid techniques. Miia, the lamia, darted through the air, her tail coiling around a practice dummy; Papi, the small harpy, flapped energetically, trailing after her friends; Kurumu, the succubus, leaned lazily against a wall, flipping her hair with an almost hypnotic grace; Centorea, the centauress, stomped the ground in precise movements, her armor glinting.
All eyes flicked toward him. Valentin's face burned red. He was painfully aware of how exposed he felt, how every instinct of desire, fear, and hunger clashed within him. Moka's hand rested lightly on his shoulder, grounding him.
"This," she said softly, gesturing at the gathered students, "is your world now. You will interact. You will train. And you will feed. Your power will come from your blood, and from the bonds you forge… sometimes intimate… sometimes mischievous… always necessary."
Valentin's pulse raced as he scanned the courtyard. Already, his vampire senses tingled, picking up the subtle rhythms of hearts, the heat of skin, the faint scent of arousal mixed with sweat. His eyes darted toward Kurumu, then Miia, then Papi, each girl radiating energy that he could feel, even from a distance. His cheeks heated at the realization: the more he saw, the more his own body reacted.
Moka's voice snapped him back. "Come. Let us start with the basics. You must learn to control your hunger, or it will control you." She led him toward a smaller training area, cordoned off from the others, where dummies were lined up and magical wards shimmered faintly.
"You bite… gently at first," she instructed, demonstrating on a dummy. "Focus on the flow of blood. Let it awaken you. Let it… guide your soul." Valentin watched carefully, his heart racing at the thought of using these skills on real students later. The implications, both thrilling and terrifying, made his stomach churn.
As he tried his first bite, clumsy and uncertain, a sudden noise startled him. Yukari, the impish girl with sharp fangs and twinkling eyes, giggled behind him. "Careful, new boy! You might bite the wrong part!" Her teasing tone sent a shiver down his spine, and Valentin turned, catching sight of her eyes sparkling with mischief and curiosity.
Before he could recover, Kurumu swooped in, her succubus aura radiating charm and heat. "Oh my, what do we have here? A newbie vampire already salivating over the girls?" Her laugh was musical, teasing, and Valentin's fangs tingled involuntarily.
"Oh no… uh, I mean…" he stammered, trying to control himself. The training was supposed to be controlled, but the combination of hunger, arousal, and embarrassment was overwhelming. He felt himself blush violently, fangs accidentally grazing his lower lip as he tried to step back.
Moka placed a calming hand on his arm. "Focus, Valentin. This is your first lesson. Control comes with practice. Your body may betray you now, but your mind must remain steady. And yes… sometimes, pleasure is part of power."
The words lingered, electric and disturbing. Valentin nodded shakily, swallowing hard. The courtyard was alive with students, monsters, and possibilities, all of it thrilling, terrifying, and undeniably perverse.
As the sun rose higher, casting long shadows across the academy grounds, Valentin realized one thing with shocking clarity: he would have to survive, evolve, and dominate this world. And to do so, he would need to feed, seduce, fight, and laugh, often all at once. Every bite, every blush, every mischievous glance from the girls would be a step toward his power—and toward the harem he would inevitably assemble.
By the time the first lesson ended, Valentin was exhausted, dizzy, and painfully aware of every instinct, every craving, and every flicker of desire in his new body. Yet, beneath the fear and embarrassment, a spark of excitement burned brightly. This was only the beginning. The academy, the tournaments, the girls… all of it awaited. And he, the low-rank vampire, was ready to step forward.
