Vampire Progenitor System

The battlefield trembled as Remu’s grimoire burst open, black fire spiraling into the sky. The air thickened, charged with malevolent energy. From the swirling darkness, grotesque figures began to emerge—twisted amalgamations of bone and shadow, their forms barely holding together. These were no ordinary constructs; they were abominations, summoned from the depths of forbidden magic.

Lucifer stepped forward. His eyes, glowing with a cold, predatory light, locked onto Remu.

”So, you’ve decided to play with forbidden toys,” he said, his voice a low growl.

Remu smirked, though a flicker of uncertainty crossed her face. ”Desperate times call for desperate measures. Let’s see how you handle this.”

The abominations lunged, their movements erratic yet terrifyingly fast. Lucifer didn’t flinch. With a swift motion, he sliced his palm, blood dripping onto the ground. The blood didn’t just fall—it hovered, forming intricate sigils in the air.

”Sanguis Aegis,” he intoned.

A dome of blood-red energy erupted around him, the abominations crashing into it and recoiling as if burned. Lucifer moved, a blur of motion, weaving through the creatures with lethal grace. Each strike was precise, his blood-forged blades slicing through the abominations, leaving trails of crimson light.

Remu watched, her confidence wavering. ”You’re stronger than before.”

”I adapt,” Lucifer replied, his voice calm amidst the chaos. ”Your tricks won’t work this time.”

He raised his hand, the blood in the air coalescing into a massive spear. With a flick of his wrist, he hurled it towards Remu. She barely managed to conjure a shield, the impact sending shockwaves through the battlefield.

”Impressive,” she admitted, her tone begrudging.

”You’re not the only one who evolves,” Lucifer said, stepping closer.

Remu’s eyes narrowed. ”Then let’s see how far you’ve come.”

She unleashed a torrent of dark energy, the ground cracking beneath her. Lucifer countered with a surge of blood magic, the two forces colliding in a blinding explosion. When the dust settled, both stood, panting, the battlefield around them scorched and broken.

”This ends now,” Lucifer declared.

”Agreed,” Remu replied.

They charged, the final clash beginning as the world held its breath.

The world didn’t breathe.

The sky twisted, bruised and black. Every cloud above warped like it wanted to turn inside out. Cracks of red lightning forked between stars, as if the heavens themselves were flinching from what was about to happen.

Lucifer blurred forward.

Remu raised her hand.

CLAAANG!

Their magic collided again, the sheer force of it tearing a gash across the battlefield. Trees split. Earth buckled. Sound vanished for a moment—replaced by pure, vibrating pressure.

Lucifer broke through first.

”Sanguine Veil.”

Blood streamed around him like armor, tightening to his limbs, spiraling into his fists. His eyes gleamed—cold, ancient, hungry.

He moved like a bullet.

Remu caught his punch with both hands, her arms crackling with layered sigils. The shockwave from the impact cracked the air like glass. Blood sprayed from her nose. Lucifer didn’t stop.

He spun—slammed a knee into her ribs.

Remu grunted, spit flying from her mouth as her body shot backward. She twisted mid-air, landed on her feet, skidding back. Smoke hissed from her palms.

”Your blood magic’s evolved...” she muttered, wiping her mouth.

”So has your ego.”

Lucifer walked slowly toward her now. Calm. Deliberate. Every step pressed red runes into the ground that glowed, then faded behind him like fading scars.

”Don’t lecture me about ego,” he said. ”You raised an army of corpses to fight teenagers.”

Remu’s eye twitched.

”And you’re the one who bathed in vampire curses just to win a fight.”

She snapped her fingers.

Three of the newly summoned abominations lunged at Lucifer.

He didn’t flinch.

”Hemomorph.”

His blood shot from the rune-lined gashes across his arms, turning into crimson chains mid-air. They snapped around the monsters’ necks, wrists, ankles—

—and crushed.

Bone and shadow imploded.

Blood splattered across Remu’s face.

She hissed. ”Tch...”

Lucifer’s boots clicked once, then twice as he walked through the dissolving remains.

”You’re out of plays, Remu.”

”I haven’t even opened the last Chapter.”

The grimoire floating behind her burst with black fire again. This time, it didn’t summon anything. It fed her. The runes around her arms and neck glowed red, then violet, then pitch black.

She screamed—

—and her body snapped back, suspended in the air, limbs stretched as cursed chains slithered up her spine.

The grimoire’s pages flipped on their own, violently, tearing at the edges.

Something old was coming through.

Lucifer narrowed his eyes. His coat rippled. The blood in his body screamed in warning.

”What the hell did you summon...”

Remu’s grin returned—but it wasn’t hers now. Her eyes gleamed with something else. Someone else.

”Lucifer,” she said, voice layered, deeper, broken.

”Do you still think blood can save you?”

Lucifer didn’t answer. He extended both arms, letting his blood pour from his fingertips, shaping into twin blades of shimmering red light.

”Try me.”

And then—

BANG.

She was in front of him.

No warning. No lead-up. Just violence.

Remu’s clawed hand struck forward. Lucifer blocked with one blade, then parried with the other, their movement so fast the sound came after the hits. She moved like a demon—faster, heavier than before.

Lucifer matched her—barely.

Every swing of her cursed hands left streaks of black energy that bent the air. Every slash of his blood blades sent out a ripple that distorted gravity.

CRASH!

CLANG!

SHHHHNK!

Their battle tore across the field. Over broken terrain. Through the air. Into the sky.

Everywhere they passed, things cracked. Time stuttered. Magic bled.

Then—Remu gripped his throat mid-air and slammed him into the dirt.

The earth ruptured on impact. A crater exploded outward.

She raised her hand, forming a sphere of collapsing gravity above his chest.

”Die.”

She brought it down.

But Lucifer’s voice rang out, even through the pressure—

”Sanguis Deus.”

The ground pulsed.

Blood erupted from below him—not just his, but the blood of every of his friends that had spilled on this battlefield. It surged up, engulfing the attack, hardening into a massive shield of red crystal.

BOOOOM!

The explosion rocked the hills. Half the battlefield lit up like a dying star.

For a few seconds, there was only silence.

Then—

The shield cracked.

Split.

Shattered.

And from within, Lucifer rose again. Floating.

His body was wrecked—blood poured from cuts across his chest, and one eye was swollen shut—but his aura was heavier than ever.

He raised a single hand.

”Your magic’s borrowed,” he said. ”Mine’s mine.”

He drew a circle in the air—

Not a spell. A seal.

A blood sigil as old as his name.

It opened slowly.

Remu’s grin faltered.

”What are you doing?”

Lucifer’s voice was low. Final.

”Calling what’s mine.”

And from the seal—

A storm of blood.

Not liquid. Not mist. Will.

The battlefield shook as the air grew dense with centuries of blood contracts, curses, memories—power. It surrounded Lucifer like a hurricane of red ghosts.

”Hemodynamis Ultima.”

He raised both hands—

—And brought them down.

A crimson beam, spiraling and alive, tore from the sky and slammed into Remu.

SKRRRRRAAAASHHHHHH!!!

She screamed—her grimoire ripping apart at the spine, black fire spewing in all directions. Her body twisted mid-air, shields shattering, limbs flailing, as the blast swallowed her whole.

The energy didn’t stop at her. It drilled into the earth, setting the sky on fire above them and breaking every ward she had cast across the field.

When the light faded—

Nothing moved.

Remu’s body fell, limp, cracking stone as she hit the ground. Her arms were scorched. The cursed runes were gone. The link to the grimoire... severed.

Lucifer landed slowly. Staggered. Dropped to one knee.

Blood trickled from his mouth.

But he was breathing.

Remu wasn’t.

She twitched once. Eyes fluttering open, barely.

Lucifer knelt in front of her.

”You could’ve walked away,” he said quietly.

”Instead, you dragged everyone down with you.”

She coughed. Blood dripped from her lips. Her voice was hoarse.

”...I thought I had to win...”

Lucifer stood up. Looked down at her.

”You already lost the moment you forgot what you were fighting for.”

He turned away as the last of the cursed flames burned out.

Above him, the sky started to clear. Stars peeking through.

Behind him, the others regrouped. Francisca floated just a bit off the ground, her three tails still blazing behind her. Mob’s coat was shredded, but he was grinning. Ruka exhaled smoke. Temmy gave a silent nod.

Ken cracked his neck.

”That it?”

Lucifer looked back at the wreckage Remu had become.

”Let’s kill her to make sure?”

”You will do no such thing.”
