( Kuoh Town )

I ran as fast as my paws could carry me, heart pounding unevenly as I fled from the magical assaults of the two powerful figures chasing me. Their spells were like lightning, cutting through the air with deadly precision.

In a moment of desperation, as a green magical bolt whizzed dangerously close to me, something instinctual inside me shifted. As if a new energy took hold of my being, my muscles twisted, my skin stretched, and suddenly I was no longer a dog but a nimble black cat.

The transformation didn't lessen the intensity of the pursuit. Spells continued to buzz dangerously around me, forcing me to twist and dodge with even more agility.

In the blink of an eye, as I leaped through bushes and raced down narrow alleys, another transformation overtook me.

Now, I was a rabbit, agile and swift, bounding as if my life depended on it. And indeed, it did.

Finally, I arrived at a dark, eerie park. The full moon cast a faint light over the uneven terrain. It was then that I spotted a human body lying on the ground, still as a stone. Without a second thought, I approached.

The smell of fresh blood hung in the air, and before I could react, an insatiable hunger washed over me. Instinctively, I took a bite of the exposed flesh.

It was at that moment the two figures chasing me arrived. Their eyes widened, witnessing what was about to happen. A single word escaped their lips in unison, "Shit."

Then, everything happened very quickly. The human body in front of me exploded into a crimson darkness, engulfing us in its shadow. The impact of the event reverberated through the park, leaving me trembling with fear and confusion.

Issei, his tousled hair spread across the pillow, was plunged into a sleep so deep it could rival a bear's hibernation. Meanwhile, Yukina, his determined sister, stealthily slid across the room, her steps as light as a shinobi's in the shadows.

Suddenly, a shrill cry pierced the quiet air of the room. "Issei nii-chan!" Yukina exclaimed, shaking him as if he were a disobedient puppet. Issei, in his deep dream state, mumbled something incoherent and twisted away from his sister's hands.

Determined to awaken her lazy brother, Yukino resorted to the fail-proof method: poking him incessantly with her index finger. "Wake up, you great sleepyhead!"

Twenty seconds of persistent poking later, the figure of Sayaka, the older and wiser sister, appeared in the doorway of the room like a heroine entering the scene. "Is he still asleep?" she asked, one eyebrow raised.

"I've tried everything!" Yukino responded in frustration.

Sayaka shook her head with a mix of amusement and disapproval. "Oh, you still have much to learn, little sister." With a mischievous smile, she gently pushed Yukino aside and approached the bed.

Watching in awe, Yukino observed as Sayaka stealthily backed away and then, with a leap worthy of an elite ninja, delivered a precise elbow jab to Issei, startling him awake.

Yukino shouted in surprise, "Nii-chan!?"

"What the heck was that, Sayaka!?" Issei exclaimed, his eyes still blurry with sleep.

"It's morning, you bat brain!" Sayaka replied with infectious energy, hands on her hips like a superhero on a morning mission. "I know we still have some time, but it's best to start the day off right. Come on, we need to feed those hungry brains before a big day!"

With a resigned sigh, Issei finally agreed to get up, lazily heading to the bathroom. As he locked himself in there, Sayaka shot a triumphant look at Yukino, her smile radiant. "And that's how it's done, Yukino. A little extra energy works wonders!"

Yukino raised an eyebrow, still puzzled by her older sister's somewhat explosive tactic. "Wasn't that a bit overboard, don't you think?"

That was a typical and eccentric morning in this family.

( Scene change )

My name is Issei Hyodou, an aspiring manga artist and currently a high school student despite missing a great deal of classes. Was I a super genius who got great grades so I didn't have to go to school? No, in fact, I was probably below average compared to most.

I simply reached the point of considering it not worth going to school. My parents didn't like that idea at all, but we'll soon find out that the problem was resolved.

I descended the stairs and passed through the living room, where his younger sister Yukina was practicing exercises in clothes that were inappropriate to say the least.

Yukina is a pretty and petite teenager with childish features. As such, she has often been described as extremely cute by anyone who sees her. She has black shoulder-length hair with bangs around her eyes and on both sides of her face, and dark golden-brown eyes that are sharply illuminated, while her face usually displays a serious expression. She has a slender and delicate body, but one should not mistake it for a fragile body that exudes a sense of acute tenacity. Her clothes were the standard Kuoh uniform.

In the midst of her stretching, she was bent over, her hands reaching for her feet while standing, That made your round butt perk up enough to give me a beautiful view.

[ Heavens, that butt right now! ]" A voice pounded in my head.

I tried to ignore the voice in my head, but my hand trembled, I was really trying, I needed to use all my willpower not to do it.

I went to the breakfast table that also served for lunch and dinner of course, we were far from being rich.

Sitting where I was, it was easy to see Sayaka, your older sister, preparing breakfast.

Sayaka is a beautiful teenager with knee-length brown hair tied in a long ponytail with a square bang hanging on the right side and green-turquoise eyes. She is seen wearing an outfit similar to a school uniform, consisting of a plain white blouse, a miniskirt, thigh-high socks, white sneakers, and her characteristic purple sweater vest.

At the moment she was wearing an apron while preparing everything, but Jesus, those breasts were out of this world.

[ Drinking milk in the morning is very important, I remember reading somewhere that when you drink from the source is when we consume all its proteins. ] The voice in my head spoke again.

"Shut up!" I said amidst my thoughts.

I waited a few minutes until breakfast was ready, and I was hungry.

"Itadakimasu…" The three said aloud before they started having breakfast. As they ate, I caught a glimpse of everyone's food.

Yukino happily ate pancakes with bacon with a childish smile on her face, she seemed to enjoy it thoroughly.

Sayaka's place was empty, but on the table was her breakfast similar to Yukino's except for the bacon she hated, she said it was pure fat, she was a heretic to cuisine, a meal without bacon was a lifeless meal.

As for my meal, well, it was Sayaka... I was eating her now... No! Never in this form!

"I-Issei-kun~" Your older sister was sitting in her place with her neck exposed, I was standing leaned over while my teeth pierced her flesh and sucked her blood.

It was an almost painless process since my teeth numbed the bite area, but it was uncomfortable because it didn't stop your sister from gasping and moaning your name, apparently the process generated a certain pleasure for the victim...

[ How delicious! You should bite those breasts, while you're not full yet.] This voice continued to bother me.

This was a common morning at the Hyodou residence in recent weeks, it wasn't always like this, but to give context we have to go back a...

( Weeks ago )

Who would've thought a meeting with a girl would end with a shaft of light in your chest? It seemed like something out of a cliché fantasy story, especially considering the girl had wings. One moment, I was on the brink of death, and the next, I found myself in a church. It felt strange, after all, there were no more churches in Japan, but there I was, staring at the cheerful figure in front of me.

"Welcome, human! Don't mind the mess. So, how do you feel? Ah, what a stupid question, I know the answer." said the mysterious figure.

She was a petite woman, probably around 5'3" at most. Her hair was long and pink, contrasting with her crimson slit eyes. She had an hourglass figure, with generous curves. And, to my surprise, she was completely naked. Despite this, she maintained a confident smile on her face, arms akimbo in a superheroine pose, unabashed by her nudity.

"Where am I?" I asked, strangely calm, though I felt completely bewildered.

"Oh, that! I stole your dead body for myself. You were delicious, thank you for the meal," she said, licking her lips seductively.

"What!?" I exclaimed, perplexed.

"First, let's do introductions. My name is Momoluke Deviluke Santaline Dracula the Third. I'm the third progenitor of the oldest vampire, Dracula. You can call me Momo." she said proudly.

I was a bit stunned by the long, pompous name, and that dream, or whatever it was, was getting increasingly bizarre.

"You died, Issei-kun, to a fallen angel. I was being chased by a pair of heavy-duty exorcists and took your body as my last hope of life. Unfortunately, this puts my consciousness in the background, leaving you in control. You are... THE FOURTH!!! YEHHHHHH! NOW YOU'RE THE FOURTH PROGENITOR! CONGRATULATIONS!" She said, as fireworks burst from her palm.

What madness was this?

"But what the hell is going on?" I said, still trying to process everything.

"You don't need to understand now, nor do I need to give many explanations. When I fully absorb you, you'll have my memories and know what happened. And, of course, you can do whatever you want." Momo explained. "But I did a few things to ease your initial contact, since you won't have access to all of my powers and those of the predecessors right off the bat."

She then huffed and continued. "First, I altered some of your life perspective. Currently, the life you live is quite different from reality, at least in your memory. Of course, everything was as real as anything else in your memories. Don't worry, I can't do this in the future. Second, the two 'hotties' who were chasing me, I altered their memories to think you are a family. They are strong enough to make me run, so they'll be useful to protect you until you're strong enough to defend yourself. Third, it's possible that some of the other two progenitors will contact you without me realizing, but trust me, you'll prefer to stay by my side on this. Any questions?"

I was full of questions, in fact, I was full of everything! Everything seemed so forced and out of nowhere, without any real context.

My mind was so focused that I maintained a composure that was like a sense of survival. "Who were the people chasing you? You mentioned exorcists," I asked, trying to understand.

"Oh, that! The church and I are sworn enemies. Don't pay much attention to that. They just got furious because I used my powers to transform into one of the priests and... well, 'confess' to several women there to rid them of their sins. Believe me, praying isn't the only thing the nuns do well on their knees HAHAHAHA!" she laughed, as if it were a hilarious joke.

It was all so bizarre, way too bizarre and without any real context! What madness was happening, after all?

( Currently )

Basically, that was my first bizarre encounter with the third progenitor.

When she fully assimilated me, some things came to light.

Firstly, Issei Hyodou died. I wasn't that boy by a long shot, probably a fusion of what he was with the third progenitor, or what I liked to think, someone without a fully formed personality at the moment.

Secondly, Momo spoke in my head, she was practically my Jarvis, just an obscene version since most of the things she did lately were to influence me to do something with sexual undertones.

Thirdly, the powers I inherited were not developed, in fact, I only had two at the moment, which was quite disappointing considering the powers Momo had despite being weakened over the centuries.

Fourthly, apparently Momo didn't leave a good mark on the world with countless centuries of mischief, from leading crazy cults of virgins who could lose their virginity to her so she could taste that blood... It was disgusting... To using her shapeshifting ability to, for example, start wars, in fact, that bitch had started most of the wars in the past centuries among respective races both human and supernatural, which made her a target... One that would surely be directed at me.

With that in mind, it was quite a displeasure, I should accumulate some points to survive... Did I want to? No, in fact, I would rather die... It's dark, but it was better than living like this, unfortunately Momo wouldn't let me die because of her regeneration, and she couldn't pass to a new host before 10 years... Apparently this thing was more like a ritual with conditions than anything else.

So I came to my own conclusion, until I could end this futile and useless life, I would do everything to the disgust of this damn vampire and make these next years a true hell.

"You can try, but I give it a week before hearing 'Yamete Kudasai, Onii-chan!'" She said to me, just like last week.

Fuck you, Momo, invading my thoughts.

Anyway, after all, my body had already taken enough blood to go out in the sun without many problems, but I didn't intend to do that at the moment.

In fact, I was going to stay here in this house for at least another 2 years until I reached my 18th birthday, I would bore her to death in that time since she hated "human entertainment" like games, books, etc. While I keep my sanity, she goes crazy, it was a good form of torture in my opinion.

Oh, and I would only drink Sayaka's blood, not provide variety, we liked the taste of blood, Sayaka's was like a refreshing, sweet strawberry drink, hopefully this taste would make her sick soon and become another punishment.

It was a bit sad to see what Sayaka and Yukina suffered at the hands of Momo, the brainwashing, being thrown into a life that wasn't theirs... Unfortunately, the same happened to me, so even though I knew their feelings were true siblings despite having the lucidity that it wasn't true, and this mind control was irreversible even if he told

them the truth, all he could do at the moment was let them have a pleasant life.

Although Momo didn't make everything clear in his memories for him. He made sure that some things were normal for his sisters, like them providing blood for him as if it were a Sunday lunch, besides some other aspects like the pleasure it generated...

After all this, this was Issei's boring life now, once a high school student who loved manga and a future renowned artist, reduced to the house arrest of a perverted vampire, life was funny.

Ring!

Unfortunately, I heard the sound of the doorbell and opened the door that day, a great regret because I found a tremendous thorn in my side that day known as Sizerch Lucifer.

(To be continued?)

Author's Note: An idea in the wind, it has some potential so maybe I'll release a few more chapters, especially since the idea came from Fullmetal's Envy basing a fanfic on Metamorphosis and how it could mess up a society, besides reminding me of Soma Cruz and the classic stealing abilities from monsters, so I unified the concept and threw it into DXD, and the third progenitor who initially would just be an eccentric personality of the MC because I read a story that had Momo from To Love Ru, made this happen... I just thought it would be interesting to mention that this is practically a blender LoL.
