UnholyGod

He just wanted a quiet vacation and a good espresso... instead, he ended up seducing half the city.

------

Lux Vaelthorn wanted three things: a good coffee, peace and quiet, and zero responsibilities.

What he got?

A mansion, a system with the personality of a deadpan butler, and a bunch of heiresses fighting over who gets to be his first “investment.”

As the heir of Greed and Lust, Lux was born to dominate markets, hearts, and boardrooms. But after centuries of cleaning up his parents’ messes in the underworld, he rage-quit Hell’s finance department and took a hundred-year vacation to the mortal realm.

His problem?

Even without trying, he’s too hot, too rich, and too damn magnetic.

His Incubus Pheromones seduce emotionally unstable rich girls like clockwork.
His Greed System scans bank accounts like X-rays.
And thanks to a “minor” celestial bounty on his soul, some entities either want to marry him… or murder him.

[Warning: 3 rich virgins detected within 15 meters. Incubus Pheromones activated.]
[Recommendation: Flee. Or flirt. Your call.]

Lux just wanted caffeine.

Now he’s got a mansion full of horny heiresses, a schedule full of power plays, and a city that thinks he’s a billionaire playboy CEO.

Fine.
If he can’t nap… he might as well rule.

Harem Startup : The Demon Billionaire is on Vacation

The dozen semi-transparent screens floated in a perfect arc around him, each displaying live infernal data streams.

[Infernal Treasury Stable — +2.4% Yield Growth]

[Soul Contract Flow: 97.2% Clean Compliance]

[Black Market Leakage: Down 43% (Sector Enforcement Active)]

[Greed Department Liquidity: Fully Balanced]

[Corruption Threshold: 0.7% — Acceptable Range]

Lux crossed his arms, nodding in satisfaction.

The thing was: most people never understood how volatile hell's economy could get. Soul inflation. Contract defaults. Black-market brokers laundering human suffering. Eternal damnation wasn't exactly a stable currency model.

And now it ran like one of those sleek mortal stock markets — minus the insider trading or at least with better managed insider trading.

"Status check, System," he whispered.
