Vampire Overlord System in the Apocalypse

-----

Clementina suddenly opened her eyes, finding herself inside a large room within a manor…

"Eh? Where am I…?" she wondered.

She sat down in the comfortable bed, and felt like sleeping for a few more hours, but the light of the sun crossing through the window would not probably let her do as she pleased.

However, she could not remember how she got into the bed to begin with…

Memories of last night slowly came to her mind.

After being turned into a Vampire by Noah and then saved from an interrogation, she was sent alongside Noah's Blood Servants and Robots towards a Dungeon to grind as many Cores as possible with them.

She remember battling there for hours and hours, overusing her powers constantly while recharging her mana by drinking the blood of the monsters present in there…

At some point, after many hours, her consciousness started to become cloudy, and like a wild beast, she fought and massacred constantly anything on her path, until she completely lost her consciousness…

And now, she woke up in here.

"I have to explore around then… But… Hm? I feel the presence of very strong people in here…" thought Clementina, walking through the room she was in and lightly opening the door.

She found a long corridor, walking through it, she heard the voices of people talking and eating downstairs…

"Hm? Are those…?" she wondered, as something at her back emerged…

A figure coated in shadows, extending a hand, and touching her shoulder!

"AAAH!" cried Clementina, startled by the hand as she fell over the floor.

She glanced at the culprit!

…It was a beautiful and thin robot girl, with gray and black colors, her beauty was like that of a robotic princess, with a stoic and expressionless yet beautiful face.

She was wearing a maid outfit too, for some reason.

"…Eh? You… Ah! You are the robot they call Big Sis, right?" asked Clementina.

"Indeed, sorry to startle you, but I used Shadow Travel to come right towards you as I see that using my Blood Core Battery Ability is more efficient than walking sometimes… Clementina, right?" asked Big Sis, who still has not gotten a proper name, although Noah called her War Machine.

"Yeah. Was I carried here while I was unconscious?" asked Clementina.

"Precisely. I carried you, in fact. You were unconscious even after we reached the manor, so I left you inside a room by Arthur-sama's orders. Did you sleep well, Clementina?" asked Big Sis.

"Yes… Thanks for taking care of me… in the dungeon we did not had much time to talk with each other, but you seem to be very nice… I have never actually spoken to a robot before, sorry if I am a bit awkward," apologized Clementina.

"Not at all. Noah-sama had given me and my sisters an introduction of who you were, Clementina Silvercrown Icespear. Oh, he seems to be calling you downstairs, so please, follow me," said Big Sis, as she touched Clementina's shoulder and covered her in shadows, both of them suddenly disappearing in a puddle of shadows…

Flash!

Just a second after, both of them emerged right behind Noah, who was having breakfast with the rest of his subordinates.

"Here she is, Noah-sama." Said Big Sis while gently bowing down her head, after having her Mana Core Battery converted into a Blood Core Battery, she gained a greater connection with Noah similar to his converted subordinates, and after yesterday's training, she assimilated a lot of Cores and monsters materials, enhancing and evolving her Shadow Attribute within her Blood Core Battery and developing the Shadow Travel Ability, giving her the power to travel through shadows of people she has "marked" with her shadow, who were at least less than 30 meters near her.

"Thanks, Noire," said Noah.

"N-Noire?" asked Big Sis.

"This is your new name, calling you Big Sis is not suited for me, and War Machine is too long," said Frank, as Noire suddenly felt a light amount of power enter her Blood Core Battery after being named… similarly to Noah's Blood Servants!

"Ah… such a wonderful name. Thanks, Noah-sama," said Noire.

"Wait… how did I got here?" asked Clementina in shock, in just a few seconds, she was teleported from the second floor to the first floor…

"Noire brought you here through her special Ability. Clementina, I see that you worked very hard, my Blood Servants and the Robots said that you were the one that fought the most. There should be enough Blood Cores for you to reach C-Rank now," said Noah.

"C-Rank?! Me?" asked Clementina.

"Yes, there are enough Cores, we don't need them as we are C-Rank, we had already achieved that Rank. And soon, we shall achieve B-Rank, in fact," said Noah.

"B-Rank…?" asked Clementina, thinking that Noah was, perhaps, making a joke.

There was no way that someone could advance to B-Rank in the span of a day and a half…

Or was it?

"Clementina, believe Noah's words, he's talking the truth," said Iris.

"I-I see… well, I better adapt to this ridiculousness fast… Now that I am a Dhampir and all…" sighed Clementina.

"Also, here," said Frank, as he gently touched Clementina's chest (not breasts, but the area above them) and activated Blood Core Creation.

"Eh?! Ungh…!" cried Clementina, as she felt the materialization of her energy begin to grow within the inside flesh of her chest.

Flash!

The crimson light quickly took ahold of itself, materializing and forming her Blood Core!

Quickly, after, Clementina experienced all of the System notifications regarding the Blood Core creation.

"You harvested a large amount of Cores, so you have enough for everything at the moment. However, we do not have enough B-Rank Cores for you, so you will go harvest them with the rest of my servants until you can catch up with us tomorrow… Do I make myself clear?" asked Noah.

"Yes… I will work hard to grow stronger, Noah-sama… And I will help however I can. You have given me a great opportunity to grow stronger, but I know that it depends on my efforts to actually become stronger…" said Clementina, realizing the wonders of serving Noah at last.

"It is good that you understand, so I don't have to force you to obey me," said Noah.

"F-Force me…?" asked Clementina, as her answer was left unanswered, being asked to join the rest of the family's breakfast by Timassa.

"Anyways, now that we are all present now, I shall assess a few things first. First of all, the Blazing Wyrm Emperor had become my Blood Servant, his name is Pride, and he is capable of speech," said Noah, as Pride emerged from a wound that opened on his shoulder, only poking out a single, enormous head made of crimson and crystallized blood.

"It is a pleasure to meet all of my lord's subordinates- And also his beloved wife…" said Pride respectfully, bowing to Iris, who he immediately realized was Noah's wife as he felt the scent of Noah's bodily fluids impregnated all over her body, and even inside of it through his sharp smelling sense.

Even though they had taken a bath after doing it, they also did it while bathing so… perhaps she was still covered in Noah's scent.

"Eh? (How does he knows?) …Yeah, nice to meet you Pride," said Iris with a gentle smile.

"Damn, so it is really the Wyrm Emperor… He became so serviceable now…" said Arthur.

"Indeed, it is surprising… Especially when he was so prideful and bold before…" said Timassa.

"I guess that's why the name of Pride…" said Jon.

"Oh right! …I guess," said Arthur.

"Noah-sama naming sense is on point once more," said Timassa.

"Dragon meat! It was tasty!" said Adamantine, who had eaten a large piece of roasted Wyrm meat that was harvested from yesterday's dungeon exploration, the meat was hard but very flavorful.

"Well, I am not really a Dragon… But I am happy that my corpse could had been enjoyed by my lord's subordinates," said Pride, being the complete opposite of his past self, the name of "Pride" didn't really fit him now.

"Aside from this, we have finally gathered enough Cores for all of us except Clementina to reach B-Rank… After our relentless effort, we had finally reached our first milestone!" said Noah, raising a cup of Wyrm blood.

Noah opened his Dimensional Storage Ring, as a large pile of hundreds of C-Rank Attribute Value Cores flowed out like a river, they were too many!

The intense battles they had yesterday paid off!

By doing something that no hunter could ever do such as battling tens of Fire Wyrms and even defeating the strong Hidden Boss who had taken many hunter lives… they were properly compensated for their efforts!

Everyone's crimson eyes shined brightly with excitement… it was finally time to leave school and do as they pleased!
