Harem Startup : The Demon Billionaire is on Vacation

"I—what—" Lux rubbed a hand through his hair. "I thought you were a banker!"

"I am a banker. I'm just not a victim."

Before he could recover, Mira lifted the other tongfa and pointed it over his shoulder.

Bang!

A second shot screamed past him—and struck another rat mid-jump, splattering its tiny, malformed head like a rotted melon.

"I analyzed their movement patterns," she said, calmly, like she was reciting stock prices. "They're weak. Agile. But clumsy in swarms. Their jump arc is predictable and their eyes can't handle shifting lights."

"You analyzed them?"

"Of course I did. I'm not about to stand around while you make a blood fountain."

Lux just stared.

Then slowly grinned, wolfish and stunned.

"I need to give you a long explanation after this."

Mira flicked her tongfas into a defensive stance. "You will."

Another screech sounded behind her.

Lux's eyes widened—too close.

He didn't think.

He just moved.

His arm whipped back and he hurled a blade like a predator's prayer, the blade slicing through the air in a spinning arc and slamming into the skull of the rat-demon mid-leap behind Mira.

-Crack!

-Thunk!

[CRITICAL HIT – Temple Pierced]

The demon collapsed, twitching violently before fading to black mist.

Lux's eyes met Mira's. "Definitely."

Then they moved together.

Like they'd trained for this.

Like war was a dance they'd always known.

Lux surged forward, summoning Amare back to his palm with a snap. The Lust Blade glowed red hot now, feeding on adrenaline, blood, and rhythm. He slipped through the battlefield like a storm, slicing rat limbs, cutting throats, rending spines in a whirl of tailored destruction.

Mira stayed at his flank, moving differently—more rigid, more precise. She used the tongfas like a surgeon with a vendetta. Parry. Twist. Fire. Block. Blast.

One tried to leap at her side—

She spun and cracked it full in the ribs. Its body folded. She shot it while it was still mid-collapse.

Lux slammed Amare through one's face and kicked another into a wall.

But they kept coming.

"Where the hell are they spawning from?" he growled.

Behind them, the pocket dome pulsed again.

[Enemy Count: 32]

[Spawning Node Detected: Left Sector – Koi Pool Core]

[Warning: Dimensional Nest Active]

"They're being dumped in," Lux muttered. "We're in a nest."

"You think?"

Another rat-demon crawled over the wrecked wine bar, chittering.

Lux cursed. "No time."

He reached deep into his system and whispered.

"Summon: GRAEVOS."

The room rumbled.

A dark sigil flared open across the ceiling, cracks of infernal flame tearing space like rotten parchment.

Then—he arrived.

Graevos.

A three-headed hellhound the size of a compact car. Each head snarled with rows of sharp obsidian fangs. Eyes glowing. His paws cracked tiles with every stomp, his back laced with infernal chainmail and cursed leather.

The rat-demons froze.

Just for a second.

Then Graevos roared—three voices, one rage—and charged.

Blood flew.

Heads snapped.

Bodies shattered.

Graevos tore through the swarm like a wolf through leaves. His middle head bit clean through one rat's torso. His right head grabbed another and slammed it repeatedly into the ground until it popped.

Lux didn't even slow.

He used the chaos.

Leapt into the air and spun.

"Hellfire Rain!"

From above, crimson magic arced into dozens of arrows—raining down over the remaining swarm. Every hit burned. Skin sizzled. Bone cracked. Smoke filled the room as demons screeched and scattered.

Mira covered her face as one exploded near her. Her dress now bore flecks of black demon blood, her hair half-loose, her tongfas steaming—but her stance never faltered.

Lux landed beside her, panting, blades glowing.

Blood soaked the floor.

Demon ichor steamed in piles.

One rat tried to escape through the barrier seam.

Graevos lunged and ate it mid-scurry.

No ceremony. Just a crunch of bone, a spray of shadowy mist, and the sickeningly wet thud of demon meat hitting the floor.

Lux didn't blink.

There wasn't time.

Because eight more were coming straight at them from the far end of the ruined restaurant, hissing, crawling over the splintered remains of the wine bar like a possessed tidal wave of claws and twitchy rage.

"Final batch," Lux muttered, blood dripping down his cheek, one eye twitching from mana overuse. "Of course they saved the swarm for last."

Graevos growled, ready to intercept, but Lux raised a hand and pointed.

"Handle those three," he ordered, voice low and sharp.

The three-headed wolf snarled in acknowledgement and launched forward, vanishing into a blur of muscle and flame-laced shadow—obedient, deadly, and already tearing through the flank before the demons even realized what hit them.

Mira was already on the move.

She sprinted forward like she wasn't wearing heels at all, dress torn at the side, hair flying in streaks of raven and blood.

Lux flanked her—daggers in both hands now, sweat sticking his shirt to his back. His left leg ached a bit where a demon's tail had clipped him earlier, but he kept going.

They met the swarm mid-charge.

And collided.

The first rat demon lunged for Mira's throat—she ducked, slid under its claws, and brought both tongfas up with a punishing crack, slamming them into its chest and flipping backward into a roundhouse kick that sent it flying.

Lux used her motion as cover, slicing through the air with Amare, carving one across the torso, then turning with a pivot stab from Devorare, pinning another to the koi pond wall.

[Debt Curse Triggered]

[Speed Buff +10% (15 sec)]

"Left!" Mira shouted.

He turned—barely in time.

A demon leapt at his side. He dropped low, let it soar overhead, and dragged his dagger upward along its spine as it passed.

Blood poured.

Another came from the shadows.

"Demonic Orbs."

Three orbs shot from above his shoulder—one imploded the demon's skull, another bounced off the ceiling and slammed into its chest, the third exploded midair and caught two more crawling up the wall.

He was running out of patience.

Running hot on adrenaline.

He glanced sideways.
