Vampire Overlord System in the Apocalypse

-----

Sakura raised her arms as she showed the entrance to her home to Noah and his party.

She lived rather far away from the center of the Central City, almost on its outskirts, within a series of abandoned buildings, where a lot of trash, scrap metal, and junk was thrown.

There were also humans living in here, and even the occasional young Subhuman running around and hiding from the presence of Noah.

"So this is… the part that we don't see of that splendorous city…" said Iris.

"Hm, a lot of prey," said Noah.

"I-I think we already got pretty filled with what we ate… No need to hunt more, Noah!" said Arthur.

"Hmph… You might be right," said Noah, as he glanced at his surroundings while walking inside the dark alleys of this abandoned building.

There were large pieces of scrap metals, even pieces of weapons, large cubes of iron, shattered Magic Core Batteries, and a ton of trash scattered all over.

Suddenly, several colorful eyes gleamed within the darkness, startling Noah's party.

"W-Who are those?" asked Iris.

"Ah, everyone, you can come out! They are friends… they just saved me from some very shady thugs…" said Sakura, as the lights over the large and dark building suddenly covered the entire place, illuminating it and revealing dozens of robots hiding within the scrap and other things.

"Sakura, nee-sama…" said a tiny robot boy that was missing an arm and whose left eye was turn off.

"Are they really… Good humans?" asked a model similar to Sakura, although she was missing her air and seemed filled with wounds that were patched back with scrap metal.

"Sakura, you idiot, get away from them! You shouldn't have brought them here!" roared another Fembot, although her legs were missing and she moved by being attached to a wheelchair, her eyes were wearing a special lens, that made them seem oddly big, and her hair was long and brown.

"But Sugar, they saved me…! I was about to… to… Sniff…" cried Sakura, as she hugged the one she called 'Sugar'.

"They also killed those two F-Rank Hunters like nothing! They are not afraid to kill humans, like big sis!" said Sakura.

"T-They killed them?! Really? I would have guessed that they would have allied with them!" said Sugar.

"They were easy prey, so we took them down to feed our family. We are not so different from you, we struggle to survive in this world, we are not normal humans either…" said Noah, as he showed his vampiric traits, the rest of his party members also did so, surprising the robots.

"Subhumans?" asked Sugar.

"Hm, perhaps I could tell you more if we can meet your leader," said Noah.

"I am here…"

Suddenly, an enormous mech descended from the ceiling, falling like a tank into the ground!

BOOM!

"W-What…?!" asked Iris.

"That's… really a war machine!" said Arthur.

"So big…" said Timassa.

"I am the big sister of my siblings… And the one that protects them from the trash of this world… That you are a subhuman or that you killed those that tried to assault her does not mean that we are instantly friends. Although I would never doubt Sakura's words, as she is an honest and goodhearted girl… I won't ally nor obey weaklings," said the war machine.

Her legs were like those of a spider, black and made of powerful metallic material, ending on sharp ends.

Her upper torso resembled a very refined Fembot, with the slender torso, arms, and an adorable face, although she covered most of it with a steel plate, only revealing her glowing crimson eyes.

The arms of her upper torso carried rechargeable magic shotguns, and she could also separate them into six arms with six blades that could slice through rock with ease.

Her entire body was black and gray, and her powerful presence and the enormous magical aura she unleashed meant that she was indeed a powerful War Machine, special Magic Mechs used to fend off Mutated Beasts on the outsides of the Sectors, or even used as incredibly expensive guards for rich people.

"Weaklings? So you want to fight me?" asked Noah, as his entire body began to cover itself with a powerful crimson aura.

"I see that you're strong… But if we fight in here… the entire building might fall off… If you want to prove yourself to me, follow me," said the war machine, walking away.

"E-Eh?! Do we really need to fight?! Big sis, Noah saved my life with his friends!" said Sakura.

"So what? I want to see how strong he is, weak allies are not needed," said Big Sis.

"So cold…" sighed Sakura.

"Well she wasn't programmed to have complex emotions like us, although she is very protective, the only way to gain her approbation is by fighting…" said Sugar.

"W-Wait, Noah-sama, are you sure you can… beat such a thing?" asked Iris.

"I-I think you might be overestimating your current capabilities…" said Arthur.

"I never fight battles I can't win," said Noah, following Big Sis as his party followed him from behind alongside Sakura and Sugar.

Big Sis reached a large empty area that seemed to have once been a stadium, which had now been broken into a wasteland and ruins.

However, this place was wide enough for the battle to begin.

Big Sis glanced at Noah once more, her body towered almost four meters above the ground.

"Are you ready, subhuman? I will not take responsibility if your entire body is broken down into pieces by my bullets," said Big Sis.

"Go ahead and do your worst," said Noah, as he quickly activated the Champion's Great Perseverance, and Blood Flow Acceleration Skills, enhancing all of his capabilities, as his pale white skin suddenly turned redder, and steam began to flow out of Noah's body!

"W-What is that? A Skill that you humans use?" asked Sugar in disbelief, adjusting her mechanic googles to see Noah with more detail.

"I-I don't know, I don't remember seeing him use such power yesterday…" said Arthur.

"It must be something new he got… Amazing, Noah-sama just keeps getting strong every day…" said Iris.

"Indeed, his strength keeps surging, we have to make sure to grow stronger as well to be more useful to him," said Timassa.

"Hm," said Jon while nodding, through this whole ordeal he has been as silent as Adamantine, he didn't enjoy talking after all.

Big Sis glanced at Noah's powerful Aura, through her eyes and Mana Detection devices, she noticed a large amount of power amassing inside of his body, and even an incredibly warmth filling him, it was as if… his entire blood was going around his body incredibly fast, increasing his metabolism to ridiculous levels as if his body had begun to boil!

"Interesting, subhuman and humans always have strange Abilities…" said Big Sis, opening the cockpits of her shotguns and firing several light bullets towards Noah without even giving him a warning!

Boom! Boom! Boom!

The bullets were small, but whenever they reached anything, they would explode loudly, as if they were small bombs!

The worst part was that they were completely made out of magic, Light Attribute Magic, to be specific!

Noah quickly realized that if he were to intercept the bullets with his claws, they would most likely explode his hand into pieces!

However, Noah smiled!

This was… exhilarating!
