Reborn As A Ghost: Time To Build My Undead Army!

-----

Emperatriz vomited black blood as she felt both of Partner's spears pierced her chest, infusing her with their corrupted energies of darkness and blood. The spears glowed brightly and rapidly began to combust into black and red flames.

"AAAGGGHHH!"

As she screamed, a giant explosion blew apart the Nightmare Demon's torso. Her head and arms were sent flying and her lower body rolled across the floor, splattering her innards everywhere while a large quantity of black blood flooded the surroundings, making the scene even more dreadful.

"Oh wow, did she die already?" Emeraldine was shocked.

"S-She is?" Beatriz was stunned that it only took Partner this much to slay her powerful big sister, glancing at the corpse and then at Partner.

"Well, we're pretty damn strong," Partner said. "So unless she's a goddess, it isn't going to be that hard for us to-"

CRAAASH!

Before Partner could finish her sentence, a giant fist made of countless fused arms and hands punched her, sending her flying at rapid speed.

Her body crashed through the Demon Castle's walls, shattering them one after another. Each wall's destruction released deadly shockwaves of dimensional energy, stacking a great deal of damage on the Vampiress.

"Partner?!" Emeraldine panicked, watching Partner slowly open her eyes, glaring into the distance. "She's not dead then! I knew it… it was weird!"

"Y-YOU DAMNED…! HUMANS…! YOU DARE…! YOU DARE DESTROY MY BEAUTIFUL FACE?!"

The furious, aberrant, and warped voice of Emperatriz reverberated through the surroundings as her Nightmare Domain expanded, corrupting the castle itself and trying to swallow her foes inside.

Her body had grown warped and monstrous. Her upper body didn't regrow, but from the wound in her stomach, hundreds of giant arms with torture tools and weapons emerged, fusing into the giant fist that had punched Partner away.

"Blowing half of her body won't kill her. We Nightmare Demons are hardier than that. We have to aim for her core or completely annihilate her into ashes," Beatriz said, having fully regenerated from her wounds. She rapidly transformed into a giant black cat-like chimera with many arms, wings, and tails.

"Very well, I suppose it's time for us to get serious then," Emeraldine nodded. Armor made of Yggdrasil Wood materialized around her, covering her beautiful face with a helmet, while her butterfly wings sprouted from her back at full power.

"GRAAAAHHHHH!"

Emperatriz roared angrily, her Domain expanding even further, trying to catch Emeraldine and Beatriz inside. She charged toward them, moving with her hundreds of arms, resembling an aberrant spider.

Her giant tools and fists smashed the floor where Beatriz had stood a second ago. Her little sister jumped away just in time as her claws slashed through Emperatriz's limbs, her aura erupting and unleashing dozens of beams of darkness against her.

BOOM! BOOM! BOOM! BOOM!

"GRRRHHH!"

Emperatriz roared angrily as several parts of her body disintegrated. At the same time, Emeraldine appeared behind her, flying rapidly and shooting explosive divine arrows from her bow. Each arrow unleashed blinding explosions of light, spreading wood over Emperatriz's body and inhibiting her regeneration.

The two girls kept at it, evading the Nightmare Demon's attacks while striking from afar, staying clear of her warped Domain, which moved through space like a strange shadow. Whenever they touched it, they were instantly weakened.

"Ugh?!"

Beatriz was caught by it just a second after evading another attack. In that moment, Emperatriz laughed, her Domain warping as thousands of hands and torture tools aimed to pierce and smash her little sister's body into smithereens. Her fists tore apart Beatriz's wings, and her torture tools dug into her flesh, making her bleed and scream in agony.

"Beatriz!"

Emeraldine roared furiously, manifesting dozens of arrows and bombarding the Nightmare Demon. Each arrow contained more than one element, becoming mini versions of her ultimate technique "Yggdrasil's Nine Realms," which combined nearly every element into one.

BOOM! BOOM! BOOM! BOOM!

"UNGGHH?!"

Emperatriz screamed in agony as Beatriz glanced back at Emeraldine. Her Domain began to distort and explode, disappearing and allowing Beatriz to escape. Beatriz quickly shapeshifted into a giant octopus wielding massive weapons made of shadows, striking her sister relentlessly from behind, tearing apart several of her limbs as she dug deeper into her flesh.

CLASH! CLASH! CLASH! CLASH!

"AAARRGGH! BITCH!"

Emperatriz responded angrily, opening the palms of her many hands to reveal red eyes firing beams of concentrated nightmare miasma. The beams bombarded Beatriz, pushing her back, while Emeraldine attacked with more arrows and magic, summoning giant pillars of light from magic circles beneath the Nightmare Demon.

BOOOM! BOOOM! BOOOM!

As the explosions engulfed Emperatriz, a shadow lurked behind her. Partner emerged, accompanied by Beatriz, whom she had brought along. She had been knocked out for a couple of seconds but was already back in action.

"She's on her last ropes, finish her, NOW!"

Partner roared, swinging her spears forward and spinning in midair after jumping toward the Nightmare Demon. She pierced Emperatriz's body, unleashing an explosion of blood, darkness, and chaos.

BOOOM!

At the same time, Emeraldine pierced Emperatriz's body with powerful arrows that sprouted into more trees, draining her energy and stopping her regeneration.

"NOOOOO!"

Emperatriz screamed as if overwhelmed, seeing Beatriz appear right in front of her. Beatriz reverted to her original Nightmare Demon form, furrowing her eyebrows at her sister.

"Goodbye, sister…"

Beatriz's claws pierced through Emperatriz's chest, grasping her Nightmare Heart with all her strength and pulling it out!

"A-Ahhh…! WAIT! WAAAAAIT!"

Crack, crack…!

CRASH!

Beatriz closed her fists, shattering the Nightmare Heart into pieces in front of her monstrous sister. Emperatriz's eyes widened, and her entire body crumbled into black ashes.

"AAAAAGGGHHHH!"

Emperatriz let out a final agonizing scream as her entire being vanished, dying on the spot. Beatriz closed her fists, fragments of her sister's heart falling to the ground.

"Are you alright, Beatriz? I'm sorry that we had to make you fight your sister…" Emeraldine said. "I wish we could have done something else or-"

"I'm not upset, if you think that," Beatriz smiled cockily. "If anything, I feel relieved. Fucking bitch, I hated her, good riddance!"

"Oh…" Emeraldine was left speechless as Partner laughed.

That was just how bad their relationship was…
