Boom!
The sky was full of dark clouds that rumbled with fury. Flashes of lightning rained down on the ground, blasting them full of small craters in seconds.
The Zenin clan stood firm as they looked at the sky full of dark clouds and thunder. They were outside, but the lightning bolts seemed to have a mind.
No lightning struck anyone that day.
Inside the main building of the Zenin Clan, a man with silver hair and a weird moustache watched as a woman with dark black hair struggled to give birth to his youngest son.
The time ticked slowly as the pained groans and moans of the women started to become lower and weaker. Her eyes rolled up as she fainted from blood loss.
But she did it and gave birth to her new son amidst the storm and the weird weather. Naobito walked to his son and couldn't hold the massive grin on his face.
Naoya Zenin was born on September 14th, 1991.
"This amount of cursed energy... I have never felt it in anyone." Naoya muttered with interest as he looked at his son, covered in his mother's blood.
Naobito looked as if he did not care for the mother of his son and his concubine as he stared at Naoya. Naoya did not cry like other babies. Instead, he opened his eyes.
[Naoya Zenin...]
'Where... Am I? Naoya looked at the blurry images in his eyes as he felt the cold breeze blow on his body. The last thing he remembers is going home from work ,and then a loud honk.
A bright flash and a loud thud as his body was sent hurling through the air before crashing onto the pavement, his neck broken, and his brains splattered on the ground in a pink splash.
[Hello, if you are reading this, then congrats. You have been reincarnated into the world of Jujutsu Kaisen as Naoya Zenin. You still have Project Sorcery, and I even made it so you can stop its frame rules without consequences. I also threw in a little bonus. You could never be the strongest with your ordinary talent, after all.]
Naoya stared at the floating letters in front of him. His mind went blank for a few seconds before relief and gratitude washed over him at this opportunity.
[The ability I gave you is Instant mastery. This ability allows you to learn anything in an instant. You could use what you learned to achieve maximum proficiency in what that thing could achieve.]
[To make it easier to understand. Let me give you an example. Let's say you learned algebra. You would instantly master how the calculations work. But it wouldn't give you the answer itself. It just gave you the way to find the answer.]
'So instant mastery allows me to master anything... I think that's perfect for an ordinary person like me.' Naoya thought with excitement as he looked at the letters with gratitude.
"Hmm? You are hungry?" Naobito said as he looked at Naoya. He was giggling, and his hands were waving uncontrollably in the air. Naoya ignored him.
"Go and fetch a nanny to feed him," Naobito instructed. The woman nodded respectfully before leaving the room. A few minutes later, a woman with an hourglass figure entered the room.
"Lord Naobito, you called?"
"You will be the caretaker for my son. His name is Naoya Zenin. I want you to make sure he is taken care of." Naobito said as he walked out of the room.
Naoko paused as she glanced at the baby bathed in blood and fluids. His eyes were bright and excited, almost as if he was excited to be born into the world.
Her eyes turned warmer and gentler as she walked to Naoya before picking him up into her arms. Naoya froze as he stared at Naoko with an imperceptible annoyance.
'A woman touched me... Wihtout my permision?' Naoya suddenly froze as the words he thought about registered in his mind. A few letters appeared in front of his eyes.
[Also, sorry. To make you take the body of Naoya, I had to give a portion of his personality to you. Bye!]
Naoya clicked his tongue and stared at the woman holding his gentle body in her arms. He allowed it to happen as he tuned the sounds out and fell asleep.
[4 years later.]
"Get to cleaning my shoes! I don't have all day." Noaya said with a sneer as he stared at the woman on her knees. She was hurriedly cleaning his shoes with a wet towel.
"Yes, young master." The woman paled as she started cleaning his shoes faster. Everyone in the Zenin clan knows what happens if you anger Naoya Zenin.
Naoya clicked his tongue before his mind went to Gojo Satoru. He was only one year older than him, and he was destined to be enemies or rivals since they were from different clans.
"Whatever, the white-haired bastard could lick my shoe clean before he would be able to beat me in a fight," Naoya said with absolute certainty as he grinned.
The woman, on her knees, looked at Noaya with confusion and concern. It is common knowledge in the clan that the young master talks to himself randomly.
'Today, I should awaken my cursed technique since everyone gets their technique between four and six years of age.' Naoya thought as he lifted his other shoe for the women to clean.
After Naoya had his shoes cleaned by the women, Naoya looked down at the merchant with a smirk. His small palm rested on her head as he spoke.
"Good job, I can see you were very focused on cleaning my shoes. As a reward, you could cook food for me in the kitchen, where you belong." Naoya said with a smirk as he walked away. The woman stood there with a strained smile.
She was accustomed to Naoya's condescending manner of speaking. Even Naoko wasn't exempt from his cruel words.
As Naoya left his residence, a massive mansion in a Japanese-style building. Naoya looked at the sky and smirked as his body vanished in a blur.
Swoosh!
Running faster than a speeding car, Naoya jumped into the air and onto a building. Like a ninja, he jumped from building to building before reaching the place he was aiming for.
Landing on the ground, Naoya looked at the front of the mansion. His father and younger brother Ogi were waiting with a gift wrapped up in sealed wraps.
"Naoya, come here. Today is your fourth birthday, and it is time to see what technique you awaken." Naobito said as he opened the door. The three of them walked inside, and Naoya stared at the room in wonder.
The room was dark, with torches on the walls to make light. In the middle of the room was a tied curse, flailing all around. Naoya was confused but not scared as he sneered at the curse.
"What is this about?" Naoya asked as he turned to his father. His cursed energy flared, and the ground under him cracked. The flailing curse froze before obediently stilling.
"You will turn four in a couple of seconds, and your technique will manifest," Naobito explained as he turned to Naoya. The wrapped thing in his hand was being unwrapped by him.
"This is a grade 3 curse. After awakening your technique, you have to kill it." Naoya said as he revealed a dagger in his hand. The dagger was a shirt and looked more like a jitte.
Naoya's eyes narrowed as he recognised the Inverted Spear of Heaven. This special-grade curse tool nullifies any cursed technique it comes into contact with.
"That's my gift?"
