Reincarnated as an Evil Harem God

Watching the wild smirk curl across Sylvaris's lips, Iselynne was left dumbfounded. Her eyes flickered with confusion. She didn't fully understand why, but something about the way he looked — the way his golden eyes gleamed with that dangerous glint — unsettled her.

He looked like he was… enjoying this. The chaos. The screaming. The incoming monster wave. It wasn't fear. It wasn't concern. It was excitement.

Though she didn't mind — after all, she had already given her heart to him — she still found herself taken aback by this part of him she hadn't seen before. Her Sylvaris… was this really who he was? A man who smiled at danger? Who looked at disaster not with dread, but with hunger?

In her mind, she softened it, trying to rationalize. He's just fearless. Confident. That's why I fell for him, right?

But in truth, she was completely missing the real reason behind that twisted grin.

Yes, Sylvaris enjoyed chaos — but not because he was some noble warrior reveling in battle. No. His mind was already swimming with far filthier visions.

He wasn't thinking about defending the city. Or protecting the people. Or earning some hero's praise.

His thoughts were drenched in something else entirely.

He pictured himself standing victorious after the battle, muscles glistening under the blood-red sky, surrounded by gasping, wide-eyed beauties. Women in tight armor, sorceresses clinging to their staffs, beastkin panting with flushed cheeks — all of them watching him, wet and breathless, desperate for the man who saved their pathetic little city.

That's right… He would show them his strength. And then, he would fuck them. Every single one of them. The safety of the city? The lives of its citizens? Irrelevant.

He had never been that kind of person. And never would be.

"Sylvaris, should we—?"

Her words never reached full breath. Sylvaris's finger pressed gently against her lips, silencing her instantly. She froze, wide-eyed, as his warm fingertip hovered there like a seal, commanding her into immediate obedience.

Her lips parted slightly beneath his touch, but no sound came out. The message was clear — silence.

Meanwhile, Sylvaris's attention had already shifted elsewhere.

He inhaled deeply, nostrils flaring like a predator sniffing the wind. But unlike the others preparing for battle, scanning for danger, Sylvaris's senses were locked onto something very different. Something far filthier.

He wasn't tracking monsters. He was tracking prey.

The delicious kind.

The kind with soft curves, wide hips, heavy chests, and trembling voices begging him later on for mercy they would never receive.

But mixed beneath the thickening stench of the incoming horde, he sensed something… else.

Something better.

He couldn't quite identify it yet, but his instincts sharpened with every breath — and his Harem God System stirred.

[Warning: Potential Threat Detected.]

[Harem Candidate Potential: Unknown.]

Sylvaris grinned faintly. Harem candidate? Inside a monster wave? Now this is interesting.

If his system was reacting during a full-scale attack, it could only mean one thing. Somewhere at the core of this entire assault… there was a beauty. A rare one. Maybe even responsible for leading the horde itself. And if that was the case…

Well.

He wouldn't hesitate to break her. Brainwash her. Claim her.

There was no mercy for enemies. Not when they were beautiful enough to join his growing collection.

He lowered his finger from Iselynne's lips, eyes sharp now, voice dropping into a deep, commanding tone.

"Follow me. Stay close. And if I ever tell you to let me fight alone—you let me fight alone. Understood?"

His golden gaze locked onto her fully, burning like two suns.

Iselynne froze completely, like an ice sculpture frozen mid-breath. The only thing that moved were her long eyelashes, trembling ever so slightly, fluttering with a mixture of excitement and nervous tension.

It wasn't fear. Not at all.

It was desire.

Somewhere deep inside her chest, his cold, dominating voice triggered something primal. She loved the way he took full control. Loved the way his words left her powerless yet safe. That blend of authority and protection made her stomach flutter and her legs weaken.

Her blood ran hot. Her lower belly burned. The truth was simple.

If he pulled her into an alley right now and pressed her against a wall, she would gladly give herself to him without hesitation, ignoring the chaos erupting across the city. She didn't care about the monsters. She didn't care about the civilians. She only cared about the man before her.

But she swallowed her urges.

There was still a battle ahead. And in her mind, this was about protecting innocent lives. About standing beside him as his loyal partner.

If only she knew what he was truly hunting for.

Without warning, Sylvaris swept her into his arms.

The sudden lift stole her breath. She let out a soft gasp, eyes wide, barely understanding what had just happened. One moment, she was standing beside him. The next — she was airborne, cradled firmly against his chest.

Her heart raced wildly as Sylvaris leapt effortlessly into the air, his powerful legs kicking off the ground with immense force. His coat flared behind him as they soared from building to building, gliding like a shadow dancing between rooftops. Iselynne clung to him tightly, her face pressing into his chest, feeling the steady thrum of his heartbeat against her ear.

The city blurred beneath them as he moved with speed and precision, closing the distance toward the western wall — the place where his instincts screamed the strongest. The pulse of danger there was thicker, heavier. Whatever was coming, it would strike hardest from that direction.

With one final graceful arc, Sylvaris landed atop the towering rooftop of the cathedral, the highest vantage point overlooking the entire western sector. His boots struck the stone with barely a sound as Iselynne gasped again, steadying herself in his arms, her breath still unsteady from the ride.

But then her wide eyes shifted.

And her breath fully caught.

Before them stretched a terrifying sight that made even her blood run cold.

A sea of monsters — endless. Millions of writhing, stampeding beasts flooded the distant horizon, their sheer numbers trembling the earth itself. The very ground seemed to pulse beneath their feet with every synchronized stomp as the monstrous horde surged forward like a living wave of death.

It looked unstoppable.

An entire army of teeth, claws, wings, and howls moving as one, rushing toward the helpless city like a tsunami made of flesh and rage.

For a moment, even Iselynne thought this might be the end.

The city could be torn apart in mere minutes.

But then—Roughly five kilometers out from the city's outer walls, something strange happened.

The very air shimmered — and blood erupted.

The front ranks of the charging monsters slammed into an invisible barrier and were immediately shredded apart. Limbs flew, blood misted the air, and bodies crumbled like paper dolls as they collided with the unseen force.

A thin, almost crystalline red glow pulsed along a massive dome-shaped perimeter — a city defense mechanism.

The protective layer.

Iselynne's lips parted in awe. "That must be… the city's bloodveil…" Sylvaris narrowed his eyes, studying it carefully.

It was likely one of the kingdom's last lines of defense — an automatic protective measure, designed to slaughter any mindless monsters attempting to breach the capital. And for the most part, it was doing its job well. Countless beasts were being turned into fine mist before even reaching the walls.

But it wasn't perfect. Some monsters slipped through. Faster ones. Smarter ones. The real threats.

And that, Sylvaris realized, was exactly why the Adventurer's Guild had sounded the call for aid. The city's defense wasn't enough to stop everything. The ones breaking through would be the true test — and the true opportunity.

He smiled faintly, watching the blood-soaked battlefield beyond.

This is perfect.

Where others saw devastation, Sylvaris saw opportunity: Opportunity to level up. Opportunity to impress. Opportunity to hunt.

And maybe... opportunity to meet whoever was strong enough to be causing the system's strange reaction.

"It's time to fight, Iselynne."

Sylvaris's voice dropped, low and steady, yet pulsing with electric confidence. His golden eyes glinted beneath the darkening sky, fixed on the approaching chaos as the earth trembled beneath them.

"Today, I'll show you exactly why I'm the man worthy of protecting you for all eternity."He turned slightly, his gaze locking onto hers, voice smooth like silk but heavy with promise."So watch me. Watch as I carve my path through this storm. Watch as I slaughter my way out of this mess… and shield you from all danger."

Iselynne's breath hitched. Her chest rose and fell quickly as her heart pounded against her ribs. She couldn't even find words. She simply stared at him, wide-eyed, completely entranced. Her Sylvaris. Always calm. Always confident. Always unshakable.

Gods… I love him… she thought, feeling her knees weaken from just hearing his voice, even with death stampeding toward them.

And then—CRACK—!

The shimmering bloodveil finally shattered.

The air rippled violently as the barrier burst like fragile glass, unable to withstand the overwhelming pressure.

A monstrous horde surged through the gap instantly — easily a hundred thousand beasts, maybe more — pouring toward the city like a living flood, teeth flashing, claws ripping into the earth, roaring as one unified scream of slaughter.

The ground shook violently beneath their feet. The sky filled with their howls. Iselynne froze for a moment in pure terror. But Sylvaris... Haha! He simply smirked.

It's showtime.
