Harem Startup : The Demon Billionaire is on Vacation

Chapter 125 – A Banshee with a Megaphone

She wanted to say something else.

Something important.

But nothing came out.

Only—

”I’m glad I came,” she whispered.

And then, like the universe just loved dramatic timing, a voice echoed faintly across the room. Magical, distant, and unmistakably annoyed.

”Lullaby! Where are you? Your mother’s looking for you!”

Lullaby jumped.

Literally.

She scrambled to her feet so fast she nearly tripped on her own boots. ”Oh no oh no—!”

Her hands flailed for a moment as the voice repeated, more insistent this time.

”LULLABY!”

”Okay! I’m coming! Don’t yell!”

She turned toward Lux one last time.

Still asleep.

Still perfect.

Still the guy she’d had a quiet crush on since he crashed that summit party and accidentally summoned a champagne hydra while pretending to be lost.

She smiled—real and warm.

”Bye, sleepyhead,” she whispered.

And then, with a quick flick of her fingers, a black rift opened behind her—gentle, almost sleepy in its flow.

She looked back once more.

”I’ll come again. Maybe next time you’ll be awake.”

Then she hopped through the rift—and vanished.

The suite returned to its calm state, faint echoes of the rift’s closing whispering like a lullaby’s last note. The light shimmered through the tall windows again, casting late afternoon gold across the carpet and highlighting the dust motes like stars frozen mid-dance. It was quiet.

Until—

FWUMP!

A feathery heap of annoyance landed beside the nightstand, flapping twice before transforming back into a sleek, sarcastic raven.

Corvus exhaled deeply. ”See? Another trouble just casually dropped in through a dimensional crack. Told ya the daughters of sins got their eyes on you, boss. And let’s not forget that cousin of yours. You’re like a limited-time event.”

He fluttered to the edge of the bed and clicked his beak. ”It’s giving me a headache. You’re not just lobbying them—you’re catching their hearts while you do it. Accidentally. Which is worse.”

Lux finally shifted under the sheets, groaning. ”And you wanna say that’s my fault?”

Corvus tilted his feathery head dramatically. ”Oh! You’re awake!”

He paused.

Then squinted. ”Wait... you pretended to sleep, didn’t you?”

Lux yawned and rolled to the side, dragging the blanket half over his head. ”I wasn’t. Well... half of it. I was sleeping. But there was no way I’d sleep through that loud voice yelling for Lullaby.”

Corvus made a noise that was somewhere between a laugh and a caw. ”Heh—Lullaby’s assistant. Always loud. Sounds like a banshee with a megaphone.”

”Yeah,” Lux muttered, rubbing his eyes. ”That asshole is always loud.”

He sat up slowly, back cracking with a satisfying pop. His hair was a mess, shirt still wrinkled from the nap, and his aura hung around him in lazy embers—like his system was still deciding whether to boot up or let him power down again.

Corvus fluttered onto the headboard and tapped it once with his claw. ”So? You gonna sleep again or what?”

Lux slouched forward, raking a hand through his hair. ”I want to.”

He really, really did.

That nap had been short but sweet. Just long enough to feel like something good might have happened, but short enough to still taste like cruelty. Sleep deprivation and caffeine dependency—the eternal duo.

”But you know me,” Lux added, reaching into his inventory with a flick of his fingers. ”I consumed that thing, remember?”

Corvus narrowed his bird eyes. ”Ohhh. Yeah, how could I forget that?”

Corvus narrowed his bird eyes, feathers ruffling slightly with that all-too-familiar mix of exasperation and dread. He didn’t need Lux to spell it out. He knew exactly what he meant.

Hellborne Extract. An Insomnis Reaver.

S-Rank. Cursed. Overclocked.

An infernal concoction brewed in the deeper pits of the underworld, originally created for damned soul slaves who didn’t have the luxury of sleep. The item cut sleep time down ruthlessly, converting a single hour into the equivalent of eight, disrupting REM tracking entirely and tossing side effects into the mix like confetti.

Lux had consumed it a long time ago.

Back in the early days. When everything had started to shift—when his father had dumped the hell’s finance department responsibilities on his shoulders and then vanished on honeymoon with his lust-fueled bride. Contracts, court sessions, demonic negotiations, trade with outer circles, soul-debt management—too many things. And not enough hours to survive them.

So, in typical Lux fashion, he found a solution.

A bad one.

But efficient.

He drank the extract like it was salvation.

And it worked.

He became faster. Sharper. Sleepless and untouchable. A machine dressed in charm and infernal silk.

Until, of course, it burned holes in his soul’s circadian rhythm. But the good news was that he could keep his sanity.

”Yep,” Lux muttered from the bed, stretching lazily. ”Tasted like ashes and regret. But cut down sleep time. Those minutes were enough for me.”

Corvus made a noise like a frustrated professor dealing with a hopeless honor student. ”Right. You’re the only devil crazy enough to down that stuff while your peers are sipping blood-champagne and pretending politics don’t exist.”

Lux shrugged. ”Thanks for the words of courage.”

He stood and stretched, abs and scars and sleep lines all on full display. The suit jacket fell from the bed, and he finally started undoing the rest of his shirt. One button. Two.

Corvus turned away with a wing dramatically shielding his face. ”What now?”

”I’m taking a bath,” Lux said. ”I’ve still got ash on me from that celestial smackdown. And maybe a little divine guilt. Need to scrub that off.”

Corvus side-eyed him. ”You’re not... you’re not gonna consume those two artifacts you stole from the Archwitness’s remains, are you?”

”Of course, I am.”

”In the bath?”

Lux glanced at him with the most deadpan stare imaginable. ”Do I look like someone who does things the normal way?”

Corvus sighed. ”This is why I have grey feathers now. This, right here.”

”Heh, you are old.”

Lux casually tossed his shirt to the floor and strolled toward the bathroom. Steam already hissed out as he flicked a hand to start the settings—temperature locked to ’hell sauna’ and pressure set to ’divine punch to the spine.’
