My Vampire Little Sister

Eyghon, Cthulhu and now Baishe.

The three Demon Lords that have been threatening humanity were now eradicated. And they were all felled by the same hands.

Mine.

Demon Lords were said to be the pinnacle of existence, humanity's natural enemies. Throughout the years, nothing the world did could defeat the monstrosities that lived for thousands of years. Their power was beyond all creatures on Earth, be it Vampires or regular humans. But today, all three of them were defeated.

By my very own hands.

"Haha… Becoming the strongest being in the world. I didn't think I'd achieve it this quickly."

Like a teenager suffering from intense delusion disorder, I raised my arms and let out a maniacal laugh. Though, I could be forgiven for my lack of class. No one in history had achieved my feats. Neither the first Vampire Progenitor nor Matriarch Innocence. Not even the Holy Church had felled a Demon Lord, yet I've placed three under my feet.

Now it was for sure… I was the undisputed strongest existence alive.

But yet, I felt so empty. After achieving my dream, I started to wonder what the point of it all was. I have been training tirelessly since I was born. Even crippled, I honed my mind through books and studies. Now, I had definitely etched my name in the history books, and the world would sing my praises till the end of time.

However… What came next?

What was I going to do now?

I felt like I had the power to do anything.

Should I rule the world like a tyrant? Or should I charge into the Demon Realm and conquer those bastards who made my life miserable in the first place? Or should I fulfil Sora's prophecy and give the World Tree eternity?

Wait, was this why the Goddess feared me? Because of my power?

The only way to find out was to confront the Goddess myself. But I wasn't in the mood to invade another World right now.

If I had to choose, my current goal would be to stop the Outer Demons once and for all. Peace hasn't arrived just because the three Demon Lords had fallen. There was still the Goddess that the Demon Lords talked about. Based on Cthulhu and Baishe's words, there might also be other Demon Lords.

So while the battle was over, the war had only begun.

But that was only an afterthought in my empty mind.

Say I defeat the Goddess and all the Demon Lords, unifying the entire Demon Realm and bringing peace to our World.

Then what?

A Vampire's life was endless, and no one could threaten my existence at my current level. What was I going to do for the rest of eternity?

And then it hit me.

What was my original goal all along? Why did I want to become the strongest being in existence? Why did I train so hard after becoming a Vampire, tirelessly learning and adapting even after becoming a Progenitor?

My lovers.

Irina, Lilith, Ysabelle and Rosalyn.

I wanted to create a World, no, a universe where all of us could live happily ever after for the rest of time. I wanted to be with them, love them, and make them happy with every fibre of my being.

Screw being the strongest in the world. Screw researching the origin of magic. Screw defeating all Demon Lords and bringing peace to the planet.

All I wanted…

… were my four beautiful lovers.

"Maybe it's time to get married?"

❖❖❖

The Outer Demon invasion ended just as abruptly as it began. After the Demon Lords had fallen in battle, the remaining Outer Demons were dealt with swiftly. Most of them scurried back into the Gate from whence they game. Others were lucky enough to escape from human detection and hid in remote corners of the planet.

However, the rest that remained weren't as lucky.

Starting from the Everwinter House, Outer Demons were being slain by the thousands. Without Cthulhu to guide and lead them, the Outer Demons fell into disarray. Matriarch Innocence joined with Irina Everwinter and created an ever-frosty Winter domain that froze every Outer Demon that invaded the Everwinter Estate.

Not only that, those that managed to escape their instant death didn't fare much better either. The battle-hungry savages of the Everwinter House sprung into action and created an ocean of blood to dye the white snow of the North red.

Baishe's minions weren't exempt from their damned fate either.

While many escaped, the Alliance had sent Hunters from around the world to exterminate the pests. The week that followed was a cleanup for the ages, with Outer Demons being slain by the thousands. The world's largest Demon hunt ensued, with humans, Vampires and Werewolves all participating to clean up the planet, by exterminating the beasts.

However, that wasn't the biggest news of the time.

Hunting Outer Demons was just an afterthought; the piece of news that the whole world had focused on was the person who eradicated all three Demon Lords from the face of the Earth.

Jin Valter.

There was no person alive who had never heard his name. No, given the circumstances, history will remember his name forever. The man who slew three Demon Lords. The man whose power went beyond the Vampire Guardian House, the Holy Church and all Hunter Associations combined. And the man… who stood at the pinnacle of existence.

There was no one greater than him. No one is more powerful than him and capable of challenging his dominance.

Such was the man who took down the three Demon Lords.

Everyone had begun to speculate. What was Jin Valter going to do now? Has the world finally gained eternal peace with the three Demon Lords eradicated? Or was Jin Valter going to be the next Dracula Bloodborne, a tyrant who forced every living creature under his feet?

And while the world was speculating, the man himself…

"Ahhh, so comfortable."

Laying down on the most comfortable cushion the world could provide, Jin had his eyes closed while his head was rubbed by a beauty. Irina, delighted that her elder brother was enjoying her lap pillow and head massage, added more pressure to her fingers as she released the stress piled up in Jin's head and shoulders.

"Do you need a back rub too?"

"Yes, please."

Turning to his back, Jin exposed his vulnerable side to Irina without questioning anything. It was a mark of complete and total trust in his younger sister. Jin's lackadaisical attitude warmed Irina's heart as she continued to give the man the best massage he ever had.

"When was the last time I gave you a back massage?"

"Hmmm, if my memory serves me right, the last time was a year ago? When I was still training under Variel to awaken my Vampire Aspect."

"That long ago?" Irina covered her mouth in surprise.

"Yeah, it's been a long time," Jin smiled as he recalled the good old days. When he'd first become a Vampire, he was a powerless newborn. He didn't know any Vampire magic, and he was barely strong enough to beat a Blood Servant.

A year had passed since then, and now, he was the hero who defeated three Demon Lords.

"We've been through a lot since then, Irina."

"You mean, you've been through a lot." The white-haired Goddess rolled her eyes. "I've barely seen you over the past few months. You just had to meet the others, even though you already had me."

"HAHA!!! You're jealous about me spending time with the other three girls?"

"How could I not be?" Irina frowned and puckered her lips. "How would you feel if I massaged three other men every night?"

"... You have a point."

Jin imagined Irina doing the things she did to him to another guy. The thought alone made his blood boil and his adrenaline pumping. As the first of the four girls who loved Jin, Irina hated losing her position. Especially since she was this close to monopolising Jin all for herself. So it was no wonder the girl was irritated by Jin's constant philandering.

"But I can't remove them from my life, no, our lives anymore, Irina."

"I know that much…"

Irina wasn't an idiot. Quite the contrary, in fact. She fully understood why Jin could never part with the other three girls. However, it was hard to ignore what you didn't like. Even after all this time, Irina hated that Jin would sleep in another girl's bed.

"How about this? I'll make you a promise."

"A promise, what kind?"

"The kind that you'll like," Jin's face broke into a smile as he shifted his weight over and brought Irina onto his lap. As she's done thousands of times before, Irina found the most comfortable position on her brother's lap and wrapped her arms around his neck.

"Irina… Let's get married."

"B-Brother?!"

"Don't panic; there's more." Jin placed his index finger on the girl's lips to silence her as his voice resonated within her ears. "I know you don't like it, but I'll marry the other girls too. However, you'll be the first one I'll marry."

"B-Brother!!!"

Irina's beautiful, winter-grey eyes sparkled with happiness and surprise. She gasped while covering her mouth. While it may not seem like a big deal to others, the order in which Jin married his four lovers mattered greatly to them.

Let's face it, there was no way Jin wouldn't marry them. It was practically written in the stars by now. However, the order in which they would tie the knot was still up for debate. If they were to spend an eternity together, everyone wished to be the first wife.

Even if a thousand or a million years have passed, even if the Earth goes into decay, even if the universe dies with all the stars in it… Whoever gets the position of the first wife will be Jin's first forever.

And for Irina, a woman who loved Jin more than anyone else on the planet, it was a dream come true. No, it was her birthright that was validated by Jin's actions.

"You will be my first wife. I know it's selfish of me to say this, but that's the best I can give you."

"No, that's good enough!" Irina squealed with pleasure. "It's plenty enough!"

"Hehe, you like it that much?"

"Of course I do! Now I'm officially Brother's wife! It's a childhood dream come true!"

"Same here, Irina." Jin watched the excited beauty jump with pure jubilation, and his heart warmed exponentially. "Marrying you is one of my most cherished dreams."

"Huhuehue… You're making me blush!" Irina slapped the massive man on the chest but didn't cause any damage to Jin. Rather, she leaned in with a flushed face and asked:

"So do I call you Brother or… H-Husband?"

"You can call me anything you like, but…"

Jin pushed Irina down on the bed and whispered into her ears:

"I'll do the same… Wifey."

"!!!"

Irina couldn't take it anymore as her eyes were filled with love, and her underwear was drenched in nectar. Clinging onto Jin's neck, she sultry spread her legs and connected their crotches. Finally, she whispered back:

"Take responsibility… H-Husband."
