Vampire Overlord System in the Apocalypse

-----

Today was finally the day.

The Crystal Family, led by their father, Granite Crystal has gathered their strongest guild members.

By their Guild Leader commands, the father of the Crystal Family, the members of the guild were given the task of… avenging Emerald!

Granite had already searched for the culprits and had even spoken with the Military School staff.

He had used money and bribing to get as much info as he could until he finally realized that the culprits behind the death of his young son were Noah and those that were with his group that day.

Everything was right…

How Emerald went inside of that cave where Noah\'s group had originally visited…

And how only one of the two parties came out, Noah\'s group.

Even worse was that no traces of Emerald nor his party were left.

It was as if they had disappeared from the face of the world.

Even more, not even blood or a little piece of flesh… nothing, everything was incredibly clean…

Where could have Emerald gone then?

There was no way that he was simply swallowed up by the earth, right?

Even more, seeing how his son was so strong… nothing of this made any sense.

But everything seemed perfectly fine as if his son and his friends had never existed or something!

The Military School registered Emerald, and his group as "disappeared" and nothing else… Leaving the case alone, without seeking any justice for Emerald\'s death!

This filled Granite with bitterness as if he had swallowed a bug.

He used everything he had to find any clues and made up his mind!

After he realized that it was Noah and his group, he immediately set a large task to his entire guild, to kill these bastards!

As long as he had power and money, he could easily cover up for anything, not even the government could do much, as one of his children was a B-Rank Hunter, who was qualified as "above the law" due to their sheer strength.

Guilds often had battles between each other, and casualties were a common thing in such circumstances… as these guilds held strong hunters, they were also above the law, and were allowed in between loopholes of society.

In the world after the apocalypse, killing was seen as normal.

Guilds would often battle against each other for territories where there were dungeons they wanted… or simply because they had disputes or grudges.

For Granite, attacking this manor was like attacking a guild, or perhaps even easier.

Because the registration of a guild and the announcement of a new guild usually took around 4-5 days due to the many guilds in standby to be approved, Noah\'s guild, the Noctem Family, has not been officially announced yet, nor their new Hunter Ranks…

So, Granite and his family foolishly thought they were not even a Guild, and that their strength could not be above D-Rank, at most.

And dealing with D-Rank hunters for such a guild was as easy as squashing an ant with one\'s finger.

After a few days of preparations, it was complete.

Granite gathered over 20 D-Rank Hunters and his four children, three C-Rank Hunters and one B-Rank Hunter, leading the large group.

Everyone equipped Stealth Accessories and was packed with many healing items and other things…

Although they were mere D-Rank at most inside of Granite\'s mind, he was still cautious to prepare well and not rush things through.

After all, he wanted everything to go perfect, and to see all those that killed his son and his friends despair in agonizing pain.

The group surrounded Arthur\'s manor since the morning, and they had been waiting for them to lower their guard… deciding to attack at night.

Granite glanced at this through a flying drone, a small, magic-based robot that was able to float in midair and record things through a camera, sending what was happening to him in the commodity of his home.

Alongside this, his four strong children were participating, which he was very confident in their strength.

A petite woman in her early twenties, with short red hair and green eyes, wearing a beautiful crimson dress, Ruby, the third daughter of Granite Crystal, a C-Rank Mage-type Hunter.

A young and slender man in his early twenties, with short blue hair and iridescent green eyes, Sapphire, the first son of Granite Crystal, a C-Rank Archer-type Hunter.

A beautiful young woman in her mid-twenties with long green hair and glowing rainbow eyes, Agate, the second daughter of Granite Crystal, a C-Rank Warrior-type Hunter.

A startling beauty with long golden-brown hair and yellow-gold eyes, her figure was slender and beautiful, with wide hips and large breasts, she was Amber, the first daughter of Granite Crystal, a B-Rank Mage-type Hunter.

All four of his children were glancing at Arthur\'s territory while in silence, their colorful eyes all glowing with strong bloodthirst.

They stood above the buildings near Arthur\'s territory, alongside their army of D-Rank Hunters who were all ready to attack at any time…

It was already late in the night, the moon was shining brightly in the night sky, however, a large cloud was slowly moving near it, and for a few minutes, it would completely cover it, leaving the Sector devoid of any light aside from the lights of the city.

"We are finally here… It is finally time to avenge our little brother… It is finally time to show these pests what a true Guild is about!" said Ruby, her petite body and adorable appearance made her aura even more terrifying as they contrasted with each other.

"Let\'s make sure to make them suffer a lot first… before we kill them… We have to slice them all up real good…" said Sapphire, the only man in the group with a slender and tall figure, glaring

"Ah… Yes, my brother… We will make sure to make them suffer… At last, it is finally time to take care of them…" said Agate while holding a large sword.

"My siblings… as the cloud blocks the moon, we shall descend and finally do as we please with these bastards… Rejoice, revenge is finally going to be served…" said Amber, her eyes glowing with golden light and furious bloodlust.

The group glanced at the manor intensively… as the clouds slowly moved near the moon...

Until… finally…

The moon was blocked by the cloud, and all the figures above the building disappeared out of thin air, moving so fast that a normal human eye would not be able to discern, especially in such darkness.

Flash! Flash! Flash! Flash!

Like flashes of darkness, all the 20 D-Rank Hunters led by the four siblings of Emerald reached the Manor\'s walls and security, system, which was very archaic, easily jumping over the walls as easy as breathing air and then reaching the large garden inside of the walls.

Then, they were greeted by the two manors resting calmly in the night, the lights of both of them were already turned off, giving the impression that the people inside were already sleeping soundly.

"The manor to the left is where Noah and the rest are… the other seems to be where Arthur\'s parents sleep. They are not a threat, prioritize taking care of Noah and his group first… However, five soldiers should go take care of them, leave no one alive," said Amber, commanding her troops as five D-Rank Hunters nodded, rushing towards Arthur\'s parent\'s manor while she and the rest of the Hunters and her siblings rushed towards the manor where Noah and his family resided…

The five hunters, who seemed to be two Warrior-type hunters, one mage-type hunter, and two rogue-type hunters quickly reached the manner of Arthur\'s parents, easily breaking apart the door and running inside, using detection-based Skills to glance at everywhere and detect any signs of life.

One of them reached to the kitchen as he felt a faint presence…

But when he entered, he only found… a puddle of blood.

"Blood? Did something happened here?" wondered the Hunter, as he slowly walked towards it to see if it was fresh, touching it with his index finger.

"It\'s… warm…?"

Flash.

"Eh?"

Suddenly, the blood… moved.

It took the form of a long, slimy tentacle, grabbing him.

The slimy tentacle then shaped itself as a humanoid hand, and another hand emerged, accompanied by another and another…

The hunter was left in shock as he saw something he had never seen before, the blood itself was moving and shaping as hands!

"W-What is this?! Nngh?!"

The hands grasped him tightly, as he could not escape!

More hands emerged as the figures of several humanoids made of blood appeared, ganging on him!

The man tried to use his Abilities to escape, and some of the figures were blasted into blood, however, more emerged, as if they were regenerating!

The figures started to punch him, to slash him with blood weapons, to burn him with magic, to hit him with blood axes, to pierce him with blood nails and blood spears!

His entire body began to be torn apart into pieces, the pain was agonizing, and the blood entities that began to tear him apart only smiled eerily at him, with empty, crimson eyes!

It was terrifying in every sense of the word!

Just what kind of creatures were these? And how did they appear here?!

Were these monsters or something?!

The Hunter did not know, as he had no time to think anyway, he tried to run away, but his legs were cut off, and his entire body was dragged into the puddle of blood!

"Nnnggh! Amber-sama…! NNGRRYAAHHHHH…!"

Not only his screams were heard, but the ones of all the group that entered this manor!

Amber, however, did not have time to assess what was happening there, because she was already busy…
