Harem Startup : The Demon Billionaire is on Vacation

Chapter 743 – Not a Useless Lord of Greed

Zavros didn’t look away.

He nodded grimly.

”Yes.” A faint smile on his face. ”We are father and son after all. He just did what I did once I knew Lux was in danger.”

Zavros looked like he didn’t know anything.

But he knew.

He knew Lux could remote into the Greed system from anywhere. He knew half the important liquidity adjustments weren’t really automated. He knew that sometimes at two in the morning, projections corrected themselves because Lux was still awake somewhere.

Overworked demon.

His son.

Lux acted distant. Cool. Calculated.

But he was always responsible.

Always watching.

Always carrying.

And Zavros knew exactly how heavy that weight was.

The air in the room felt heavier for a second. Not magical. Just intention.

”I am the Hell’s economy protector,” he continued, voice low, steady. ”Yes.”

His fingers tightened slightly around her waist.

”But before all that... I’m my family’s protector.”

The words weren’t loud.

They didn’t need to be.

”I am not a useless Lord of Greed.”

His eyes flickered with something dangerous.

”I have vaults no one knows about. Assets no one dares to audit. Contracts older than the King’s throne.”

Seraphyne felt the shift in him. The steel beneath the suit.

”I have forbidden artifacts,” he went on. ”And I have money.”

A faint, sharp smirk curved his mouth.

”If Lux needs an army, I’ll fund it.”

His voice dropped further.

”If he needs a fortress, I’ll build it.”

His hand slid up her back slowly.

”And if he decides to split this infernal realm in half...”

His eyes glinted.

”I’ll supply what he needs.”

Seraphyne stared at him.

Silent.

Processing.

Then something inside her hardened too.

Her shoulders straightened.

”Then I will do my part.”

Her tone changed. No more trembling.

”Network expansion. Quiet alliances. Social webs that don’t look like webs.”

Her lips curved faintly.

”For us.”

She met his gaze directly.

”For Lux.”

Zavros studied her for a moment.

”Keep it low key.”

She nodded once.

”Of course.”

A beat.

The tension didn’t fade.

It shifted.

From fear.

To resolve.

She stepped closer.

Not fragile now.

Focused.

Her fingers slid up his chest, slow and deliberate. Not playful. Not teasing. Grounding.

”I like when you’re serious,” she murmured.

She rose slightly on her toes and kissed him.

Not frantic like earlier.

Not desperate.

Controlled.

Intent.

Their lips met and held. Slow. Deep. Familiar.

His hand moved to her waist, pulling her closer, not out of panic this time but alignment.

They weren’t clinging.

They were syncing.

War mode.

Family mode.

She traced her fingers along his jaw.

”You better not fall before him.”

A faint smirk tugged at his mouth.

”I won’t.”

She pressed her forehead to his.

”If the King thinks he can corner our son—”

”He miscalculated,” Zavros finished calmly.

Her hand slid to the back of his neck, fingers threading lightly through his hair.

”Then we correct the market.”

He huffed softly.

”That’s my wife.”

She kissed him again. Slower this time. A quiet promise.

Not dramatic.

Not loud.

Just two sovereign demons deciding, silently, that if Hell wanted to test their son...

Hell could test them too.

Then it stopped being quiet.

Zavros’s hand slid from her waist up her spine, fingers tightening like he was anchoring himself to something real. Something alive. Something not made of contracts and contingency plans.

She felt the shift instantly.

Not fear anymore.

Fury.

Protective. Territorial. Unhinged.

Her lips pressed harder. Hungrier. The softness burned off in seconds. She bit his lower lip just enough to draw that faint metallic taste. He growled low in his throat.

”Seraphyne...”

”Don’t,” she breathed against his mouth. ”Don’t talk.”

He didn’t.

His hand moved down her back and gripped her thigh, lifting her without effort. She wrapped around him instinctively. Demon queen. Lust incarnate. Not fragile. Never fragile.

He carried her to the desk in three strides.

The same desk Lux had been calmly logging apocalypse-tier artifacts on minutes ago.

The irony wasn’t lost on either of them.

Zavros set her down on the polished obsidian surface. She pulled him closer by the collar, dragging him back into her mouth like she planned to devour him.

Clothes got in the way.

They always did.

She shoved his jacket off first. It hit the floor without ceremony. His shirt followed, buttons scattering somewhere under the couch.

He tugged at her robe tie, not gentle. The silk slid open, exposing warm skin, curves, power wrapped in elegance.

They weren’t careful.

They weren’t trying to be.

This wasn’t slow romance.

This was two ancient predators grounding themselves in each other because something had almost taken their child.

His hands traced over her sides, firm, possessive. She arched into him, nails dragging down his chest, leaving faint red lines that faded almost instantly under demonic regeneration.

He kissed her throat, her jaw, the curve beneath her ear. She exhaled sharply, fingers digging into his shoulders.

”You’re shaking,” he murmured against her skin.

”Shut up.”

He smirked faintly and kissed her again.

Feral.

Unfiltered.

She pulled him closer with her legs, robe sliding further down her arms until it pooled at her elbows.

Their auras flared, Lust and Greed colliding, feeding each other in that familiar destructive harmony.

Not chaos.

Not loss of control.

Just intensity.

She leaned back slightly against the desk, looking up at him with that sharp, dangerous gaze.

”If anyone touches him—”

”They won’t,” Zavros said, voice low and steady.

”And if they try—”

”They won’t finish it.”

Her lips curved slowly.

”That’s why I married you.”

He kissed her again, deeper this time, slower. The kind of kiss that said this is war and we are not losing.

Then...

Accidentally, a small crystal detached from the underside and floated upward.

Projection crystal.

Personal.

Encrypted.

Only him.

She watched him, breathing still heavy.

”What is that?”

Zavros activated it.

The air shimmered.

Holograms unfolded in layers around them.

Not public assets.

Not standard Greed logs.

Hidden fortresses.

Invisible structures scattered across realms.

Supply routes.

Undead legions bound by debt contracts.

Soul armies marked with Greed sigils.

War logistics mapped in perfect, ruthless clarity.

”I told you... If Lux needs an army,” Zavros said quietly, pulling her back against him as the projections glowed around them.

He rested his chin against her shoulder.

”He already has one.”

She stared at the floating war network in silence.

Then smiled.

Sharp.

Unhinged.

Hell wasn’t ready for this family.
