Harem Startup : The Demon Billionaire is on Vacation

Chapter 43 – I Want Her

Lux sat there for a long moment. Staring at where Elyndra had been. The way she moved. The weight of her words.

There was silence now, save for the clink of cutlery, far off. Staff clearing dishes. Muted conversations behind glass. But Lux wasn’t hearing any of it.

His eyes still lingered near the doorway she disappeared through.

And then—quietly, like an honest confession dragged from the depths of his ribcage.

”I want her.”

A beat.

[Didn’t you just have a broken heart because Naomi left?]

Lux’s eye twitched slightly. He leaned back in his chair, arms crossed.

”Yeah,” he admitted. ”But she told me to have fun with them.”

[So now you’re just following orders?]

”I’m a good boyfriend,” Lux said innocently. ”I listen.”

[Hm.]

He sipped the last of his coffee. It was lukewarm now, but it didn’t matter. The bitterness matched the quiet hum beneath his skin—the part of him that hated being still.

”But before I spiral into a morally questionable harem arc,” he muttered, ”I need a car.”

He turned toward the restaurant window, gaze narrowing at the streets below.

Gridlock. Horns. Endless rows of cars barely moving.

Lux sighed. ”Ugh. Or a flying car.”

[Mortal realm still doesn’t have flying cars, sir. Unless you’re referring to helicopters, but those require helipads and draw a lot of attention. Which I assume is not optimal, unless you enjoy being swarmed by the press.]

Lux muttered, dragging his fingers through his hair. ”Then a motorcycle. At least I can weave through traffic like a smug bastard.”

[Excellent choice, sir. Black, sleek, dangerous—fits your brand.]

Lux stood up, rolling his shoulders. ”Yeah. Once I get that, I’ll walk around the city. See what kind of idiocy this realm calls entertainment. Maybe eat more food. Touch grass. Be normal for like five minutes.”

He paused. ”But first...”

His voice dropped into something darker.

”I need to activate that artifact.”

He stepped out of the restaurant, posture already shifting. The casual elegance of a man on vacation faded—what returned was something colder. Sharper. The Devil’s CFO walking back into the realm like he never left it.

People turned.

Some women followed him with their eyes, uncertain if they were admiring him... or being pulled into his gravitational field.

Lux smirked in return. But didn’t slow down.

His steps carried him through polished halls, gold-trimmed elevators, marbled corridors that echoed under his boots. And then—his suite.

He entered.

Took a breath.

Room service had already cleaned. The silk sheets were remade, the scattered clothes folded neatly on the couch, the scent of citrus and cinnamon lingering in the air.

The calm before the storm.

Lux stepped out onto the balcony. The city below was still chaotic. Buzzing. Pretending it mattered.

He looked over the skyline, hands resting on the rail.

The drive in him—that drive—was still burning.

He couldn’t dominate the realm.

Not legally.

He’d signed that agreement.

No world domination.

No infernal takeovers.

No apocalypse contracts.

Boring.

”Maybe I’ll conquer it economically,” he muttered.

He scoffed at his own words. ”Of course I would.”

Then he took a breath.

Lux whispered, ”Inventory.”

[System Notification: Item Found: Seraph’s Limitbreaker Core- Sealed by Heavenly Powers.]

A flicker of light shimmered before him, golden and iridescent, unfolding like an ancient vault door. And in his hands—there it was.

The artifact.

A divine relic, forged from the heavens themselves. It was meant to be sealed, guarded—or perhaps worshipped.

Lux stared at it. The shape was otherworldly, crystalline, shimmering like crystallized law. It was wrapped in chains of angelic inscriptions that glowed softly, each symbol pulsing with an ethereal light. The artifact hummed, vibrating with judgment and glory, a presence of pure power.

Lux grinned, his excitement evident.

”Now...” he whispered, licking his lips. ”...we raise the devil.”

His hand glowed with a dark, fiery aura.

”Consume.”

The relic didn’t shatter with a bang, but with a soundless rupture, as though it was devoured by the very fabric of reality.

Magic curled around him, a wave of fire rushing through velvet. The sensation wasn’t a simple surge—it was a burning, a molten heat coursing through his veins, turning his body into a furnace. He could feel it in his chest, a searing warmth that spread, every inch of him burning with power.

Pain? It was there, sharp at first, like every cell in his body was being torn apart. But it faded quickly, replaced with a dizzying warmth, as though the power was sinking into his very soul.

It didn’t vanish.

It became him.

Lux stood motionless.

Then exhaled.

Like he’d been holding it in for decades.

The surge... it wasn’t violent.

It was quiet.

Like slipping into a new skin that had always been waiting for him.

No resistance.

Just truth.

He looked at his hands. Still the same. Still pale, long-fingered, elegant. But now they trembled slightly—not with weakness.

With too much.

He could feel it in his bones.

His limit was gone.

Everything was up from here.

Power dripped from his skin like invisible ink, and the balcony’s wards flared for a split second before bending to his new state.

And somewhere—Lux knew—a trumpet was blowing. Not the apocalyptic kind, but a very, very pissed-off angelic creature watching the destruction log tick. And it wasn’t just the angels. There were demons who’d never liked him either—too many to count, all seething at his every move.

Lux smirked, savoring the moment.

”Oh, I love this,” he murmured. ”They really give me the good stuff.”

The sensation of power still simmered in him, and with a confident stride, he turned toward the suite.

He smiled—wide, wicked—a grin that made him look like someone who’d just been promoted from CEO to goddamn legend.

His grip on his destiny felt firmer than ever, and as he walked away, the world around him seemed to bend. This was just the beginning.
