Strike the Blood: The 4th Primogenitor

Third Person PoV

Kojou entered the room and saw darkness, no lights were on, but it was not a problem for him, vampires are creatures of the night, and he had excellent night vision.

He slowly closed the door behind him, and just as the door closed, multiple chains made up of magic shot at him from all directions.

They were black, unlike Natsuki's purple chains. Kojou couldn't jump back, the door couldn't stop him but he would rather not destroy his own house.

Shields popped all around him, securing his safety instantaneously. The chains bounced off the surface of the diamonds.

But Kojou quickly raised a second layer behind the chains and crushed them in between the two layers.

He then focused his eyes on a corner in the room, where a purple glow was emanating.

Aya stood there, in her hands rested a grimoire, glowing eerily.

"Natsuki-chan returned that to you?"

"Indeed."

"So we chill now? I brought dinner." Kojou said blandly.

"For now, yes. But I won't stop, you will falter for a moment and I will capitalize on that."

Kojou looked at her then switched on the lights and gave her the plate. Aya sat down and ate it, graciously.

Her manners didn't seem to have suffered in the prison barrier.

"So you are going to continue attacking me like this?"

"Yes." Aya said without missing a beat.

"Well, that is not problematic at all. What about the others?"

Kojou said sarcastically and seriously at the same time.

"They can be used to gain an upper hand."

"Then it would seem like I need to take some measures."

"Like what?"

"Thinking. But you really aren't going to stop? Like you saw how terrifying I can be."

"Yes, at first I was scared, but after calming down, thinking, and talking to Natsuki. I figured that was not what you are most of the time."

"And she knows you are going to attack me?"

"Yes. She said you have your ways to make me understand."

"Oh, I have. But my ways are way different than what she thinks." Kojou said mysteriously.

"Hmm, what would they be?" Aya asked seriously.

"You will see soon. Anyways, now that you have your fill, can I have mine too?"

"You want to drink my blood?"

"Yes."

"Go ahead, it will give me more chances."

Aya loosened her Kimono, showing off her nape and bountiful cleavage, it would seem she went commando at least for the top, the bottom remained unseen.

Kojou reached near her and took a whiff of her nape, savoring the smell, and then suckled on it for a while.

Wetting the place enough, his fangs took their position and punctured her soft skin. Aya to her credit didn't fidget or gasp at any of this.

But Kojou's plan was devious. As a vampire when one bites their prey, they don't only drink their blood but inject things also.

The majority of that is the healing saliva of the vampire, which quickly heals the holes, second is their venom, which transforms others into vampires.

The third is their pleasure-inducing substance. It had been there to make it so the prey struggled less, most vampires can't control how much of that to inject, and only small amounts got into the prey's bloodstream during the drinking.

But Primogenitors were different, they could accurately control all of that, thus when Kojou was finished drinking, he began injecting his pleasure substance, into Aya's bloodstream.

And finally, some movement was seen, its effect was quick. Her legs began to quiver and rubbing her thighs became instinct.

But that wasn't enough, Kojou dosed her enough to make normal people faint, but she was a pseudo-vampire, thus her tolerance was much higher.

Her hands grasped Kojou's back and began scratching his clothes as if wanting to rip them.

But Kojou broke free from her grasp and wiped the blood from his lips. He looked at Aya who looked like she was burning in ecstasy.

"What~ did you do!?" Aya said with gasps in between her words.

"Well, this is one of the methods. Enjoy your night!"

Kojou said as he switched off the lights and went out of the room. Leaving Aya to her agony.

Slowly her reluctance and defiance crumbled as her hand entered her cave while the other pinched her perky nipple and a soft moan tore from her throat.

…

A week later.

"Nagisa and her class are scheduled for a trip?"

"Hai, I believe she hadn't had the time to explain it to you."

Yukina said to Kojou as the two rode the monorail.

"It's a week from now on. Man, it will be a lonely three days."

"What are you talking about, senpai, Aiba-senpai, Sayaka-san, and Adelard-San would be with you. Not to mention you even have Aya-san."

"Indeed, but Sayaka said she is going to be punished by your master, while Asagi has to do a thorough checkup of the island management, there have been too many instances where it failed. Adelard, well either she is busy teasing me or talking about Alchemy, and Aya would rather have my head."

Kojou said in one breath, the monorail stopped and the two of them stepped out of it and went to their respective buildings.

But before Kojou could enter his class, he sensed a very familiar magic. A magic he was used to being his.

"My familiars?" Kojou muttered before a thought hit him.

"Is one of the missing familiars on the island and is being used."

The more Kojou thought about it, the more correct his theory seemed to him. He saw that Asagi was in the classroom already and motioned to her.

She quickly came and asked.

"What happened?"

"I need to bunk this class, somehow make an excuse!"

"What?"

"Yeah, I feel as if one of my missing familiars is on the island, and was used."

"Fine! But you owe me, go take care of that."

She said before giving him a peck on the lips. Kojou smiled and began running as soon as he was out of any prying eyes, he immediately teleported.

Kojou appeared in an alley and found it empty.

"What is it with dark alleys and problematic situations?"

Kojou muttered as he walked out of the alley, he tried to sense his magic but failed to do so.

"Seems like it is not being used."

He began to walk around peeking into the various alleys hoping he would manage to find who was using his familiar.

And once again he sensed it.

"There!"

Kojou ran with speeds surpassing vehicles and quickly reached the spot, another dark alley.

He cussed at the gods of fates and rushed in and the scene made him freeze in shock.

"What the fu- Hell!?"

…

At the same time, Kojou was searching for the magic. Yukina was in the girl's locker room changing her clothes.

PE class had long since passed but due to her doing a job for the teacher, she was alone in the room.

"What was that dream in the morning?"

Yukina took out her school uniform but before she could wear it, a crackle sounded behind her and a blue glow illuminated the locker room.

Yukina quickly moved but was slower than the invader. Two palms landed on her uncovered abdomen.

She crashed into the locker making a dent in steel and crumbled down. She gazed at her attacker and was shocked.

"How?!"

But her consciousness was reaped by the next kick that landed on her face.

…

Natsuki Minamiya was sitting in her office, enjoying her coffee. While Astarte was handling some rambunctious demon who caused trouble in the eastern giga float.

"Hmm?"

The voice inadvertently leaked out of her mouth as a magic circle appeared out of nowhere in her office and began radiating a red glow, and before she could do anything.

A mist released from it and a figure stood in it. And seeing it made Natsuki go wide-eyed.

"How did you come here?"

…

"What the fu-Hell!?" Kojou managed to turn his words into something else because in front of him were standing two girls.

One from the looks of it around ten while the other looked to be around eight. What shocked him weren't their ages but their appearance.

One of them was the carbon copy of Kanon with the only exception being her hair, which was the same color as of Kojou.

And the younger one looked heavily like his mom, with Sayaka's eyes and hair color. The resemblance was too uncanny.

And the following words made the suspicion which was gnawing at Kojou's mind for a while even more solid.

"Papa?"

The little one said with a tilt in her head. The act was cute enough that Kojou took a step back, involuntarily.

And the older one didn't fall back too much either.

"Father?"

"Guh! Too much stuff at once."

With that Kojou knew the magic he had sensed wasn't his missing familiar, but his future daughters.

Just then he saw a blonde vampire shivering in the corner of the alley. He looked very familiar to Kojou.

"Hey, aren't you the one who was hit by Himeragi?"

The blonde looked up and saw Kojou and ran behind him.

"Hey, help me, those girls are monsters!"

"Papa, that guy was trying to harm big sister!"

*Boom*

The vampire was thrown into the garbage dumpster, the moment the sentence finished.

"I remember your magic, wait until I deal with my other problems."

Kojou said with a heavy growl and then quickly ran up to the two. He landed on his knees and picked up the little girl.

"What is your name, little girl?"

"Mayumi Akatsuki! Papa's favorite child!"

"Right? What's your name princess?"

"Keiko Akatsuki."

"Hey, you two want some ice cream?"

Kojou asked as he grasped the hand of Keiko and picked up Mayumi in his arms.

"Yeah! Ice cream."

"I would like that!"

"Then let's go."

Kojou said as he took the girls out of the alley, from the darkness into the light.

…

"So you created time travel using a mixture of science and magic, and even made it so that causing trouble here, as long as it isn't severe is fine, you can even create a consistent time loop so that in the future you will again come back here making it happen an infinite number of times."

"Yes, professor."

"Honestly. Aiba and Akatsuki really created a monster. So why are you here?"

"Really Professor. You aren't even going to ask my name?"

"I have seen enough to know about you."

"Moegi Akatsuki."

"Did she take reference from that pesky AI of hers?"

"What AI?"

"Hm? Let's leave it at that, you still didn't tell me the reason for your presence here."

"Fine, I won't ask, but did he make you grow up?"

"What do you mean?"

"Like aren't you a mature lady in her late twenties? You look like a middle schooler right now."

"Ho? Aiba didn't have such guts, truly Akatsuki's spawn."

Natsuki changed her appearance by canceling the illusion, showing her true self.

"Wow, those are big."

"Akatsuki!" The English teacher reprimanded the blonde girl.

"Calm down, anyways help me look for Reina, she should be around somewhere too!"

Said Moegi before jumping out of the window and going somewhere.

"These days I am going to die because of an Akatsuki!"

The witch said exasperatedly before going to search for whoever this Reina was.

…

"So Kanon-chan, are you excited for the trip?"

"Hai, I am excited."

Nagisa and Kanon were talking while walking.

"Ne,ne wasn't Yukina-chan really cool today during PE? She jumped over the bar like it was nothing!"

"Hai."

Just then the two of them saw Yukina collide headfirst into the glass door.

"Eh? Yukina-chan!"

Nagisa and Kanon went to help her and saw that she was fine.

"Are you fine, Yukina-san?"

"Eh, Angel-chan?"

"Ano, Yukina-san are you fine?"

"Ah, yes. Kanon-chan."

"Yukina-chan, are you really fine?"

Nagisa said as she checked the temperature of Yukina by hand.

"Yes, I am fine, Aunt Nagisa."

"Eh? Aunt, That's so harsh Yukina-chan! I know people say I am like the old woman of the family but that is too much!"

Tears welled up in her eyes.

"Ah! I don't mean that Aunt-!"

"There you said it again!"

Nagisa said before she ran away, leaving Kanon to follow her.

"I think you should apologize, Yukina-chan "

"Yes." Yukina said dejectedly seeing the two leave her alone, but someone else popped up.

"Transfer student!"

"Hmm? Are, Natsuki-chan? You really are small!"

Yukina said as she began to head pat the loli teacher.

"Hmm? Your guts have increased exponentially since the last time I saw you!"

Her fan landed on Yukina's head and a ripple was created. Natsuki's expression cajoled quickly as she held Yukina's wrist.

"You! Come with me, quickly!"

"Wha- Natsuki-chan?"

Yukina or more accurately, Reina said before she was whisked away by the witch of the void. Appearing in her office, Natsuki said,

"Now, where is that brat of a sister of yours!"

"You've met Moegi?"

"Yes, now stay put till she comes back."

"You aren't going to find her?"

"I am not her babysitter!"

"But you did do that."

"Don't tell me!"

"Okay!"

…

"So, are you an alternate me?"

"Nah! I am you, but the upgrade."

"So you are an alternate me!"

"Nope, I am the better you!"

"Then you are an alternate me!"

"Neither, I am your daughter!"

"Wait, that means you are a little me?"

"Yes, wait, what?"

"What?"

The debate continued till Moegi remembered that she had better things to do than to argue with her to be future mother.

…

"Hmm? Did I sense it correctly? Kojou should have too. But he didn't come here?"

Vatler mused as his eyes, shielded by the sunglasses gazed at the bottom of the Itogami island.

"Let's try something! Upananda!"

His familiar rushed beneath the island. And was promptly destroyed. But Vatler didn't get scared or sad but instead got excited.

"Hahaha!"

A huge surge of magic happened and from the hole, a Dragon appeared and vanished as soon as it saw Vatler.
