After my initial excitement, I realized how absurd my situation was. Could this all be a dream? I lost myself in thought when a woman slapped my backside. My body responded on its own, and I started to cry.
I noticed the happy face of the person who hit me. Voices surrounded me, but none made sense. I looked to the side and saw her talking to a woman with black hair and black eyes, more beautiful than any model I had ever seen.
Despite her smile, her face appeared pale—almost corpse-like, as if something had drained all her strength.
I soon realized she was the mother of this body—and also of the child beside me. The woman who hit me walked over to the other child. Her clothes suggested she was a maid. At least money would not be a problem in this new life.
I watched as she slapped the other child. Unlike me, the child showed no reaction, just stared at the maid with those dark eyes.
A single look into those eyes told me this was not a normal Middle Ages. I screamed internally, imagining countless ways to put my plan into action. I kept my gaze on the child and saw the maid tremble under that stare. She then spoke to the mother with a discouraged look.
Nothing about the child beside me seemed normal, even in this world. The two women spoke in an incomprehensible language. My supposed mother coughed and then fainted.
A group of people rushed over and surrounded her, arguing among themselves. After a long wait, someone entered the room. He wore a long cloak lined with white fur, had a cold and imposing gaze, black hair, and pupils as dark as night.
I looked at him. He met my gaze with such intensity that my small body shivered, and I started to cry again. He seemed to find the situation insignificant and turned his attention back to my mother.
The tension in the room or my weak body made my eyelids heavy. I fell asleep before I could fully close them. Just before drifting off, I saw him look at the child beside me with anger—or maybe disgust. I knew it was not the look someone gives to a person they like.
I woke up in the same room, the same child beside me, staring at the ceiling with a neutral expression. With nothing else to do, I observed her. The dark outline of her eyes and purple pupils revealed she was a girl—probably my twin sister.
A spark of inspiration lit up in my mind. I remembered the teachings of YandereMaster69 from the start of my journey:
"YandereMaster69, I've concluded that creating a yandere is impossible. Even if it were possible, why would I want to create a woman who might try to kill me?"
"Noah, I'm disappointed. You still don't understand—creating a yandere isn't simple. Any mistake can lead to the classic ending where she tries to kill you. However, I've spent my whole life studying the perfect method to create the ultimate yandere."
"If your method is so perfect, why have you never succeeded?"
"This method requires contact from the very beginning of a person's life. You must shape them, make them dependent, and if you notice anything unusual, always maintain the facade of innocence. Never end up in a 'nice boat' situation."
"What do you mean by a normal facade? And what's with the boat?"
"Don't question it, Noah. Try it with people close to you. Help them, support them, be there in their difficult moments. Remember, you can't beat the patient guy—he's unbeatable. Relax, this type of yandere is harmless; even if you have twenty girls, she won't care."
Ultimate... The word kept spinning in my mind. With this new life, could I finally follow the perfect method?
I looked at the baby, determined to follow my master's words. She would be the perfect target. Having a cute sister supporting me with all her heart sounded ideal. In my previous life, my sister was a demon incarnate. As my master said, this type of yandere is harmless.
Even if I get a girlfriend, my sister will support me wholeheartedly. I'll be her favorite brother. Who would have thought my master's teachings would be useful in another life?
My new goal is to test my master's teachings on her. After that, I'll conquer even a dragon. I see the potential in this reincarnation. Like every reincarnated protagonist, I must have powerful abilities—enough to escape if my plan goes wrong.
I celebrated my plan internally. Sleep overtook me again. My weak body betrayed me, and my eyelids closed.
A message appeared: Congratulations, you have received the Mega Super Reincarnation System! You were born to have a mega harem, and with my powers, you'll be irresistible to the main character.
That's what I'm talking about! Reading all those books wasn't useless after all. So, how do I use this system?
No secret, user. Just click the accept button.
A transparent button appeared in front of me. I clicked it.
Congratulations on accepting the Mega Yaoi Harem System! Now complete the missions. If you fail, the user will die.
— AAAAAAAAAA!
I woke up startled and crying, something running down my legs.
Several maids entered to change me.
Although it was extremely embarrassing to be seen like that, I felt relieved to know it was just a nightmare.
Little did I know that would be just the first of many embarrassing situations in my new life.
