Aki Hayakawa..

At night, near Sugisawa Municipal High School, in a small convenience store, a young man stood in a small line to buy some Ramen. He suddenly gazed at the sky, as if he felt something.

The young man had long, black hair that hung loose, and his eyes were blue. An unlit cigarette dangled from his mouth as he paid for the items with his card at the counter.

"Thank you for your purchase," the cashier said with a smile. He nodded back with a small grin and took the plastic bag. Instead of going his usual way, he headed straight towards the cursed energy he had sensed.

After walking for a while, he reached the end of the well-lit street. Suddenly, a large bird-like spirit emerged from a portal in front of him. He placed his hand on its leg and held on tightly as it soared into the air.

He thought, 'This must be where Ryomen Sukuna's finger is located,' as he observed the building radiating an intense and dark cursed energy.

Directing his spirit towards the school building's roof, he leaped off when it came close, landing gracefully on top of the roof. He dispelled his curse as he touched down.

Sensing the cursed energy right below the floor he stood on, he did what anyone would do and stomped his foot. About two meters of the area around him crumbled, falling with a thud. The sound and dust settled after a few seconds.

He noticed two boys around his age in the area. One of them was holding a girl and a boy, while the other had two protective wolves by his side.

The boy with pink hair, who was also holding the girl and boy, looked a bit bewildered and asked, "Who are you?" with a surprised expression.

"Oh, me? I'm Aki Hayakawa," he replied, not showing much external reaction, but secretly feeling a bit excited to meet Yuji Itadori and Megumi Fushiguro.

"Fushiguro Megumi, Itadori Yuji," the black-spiky-haired boy introduced himself and his friend. He was about to grab a finger from Itadori's hand, but before any of them could react, a curse emerged from beneath Yuji, lifting him into the air and then throwing him down.

Aki was taken aback; this wasn't what he had seen in the anime. He had focused his attention on what was happening above him, where he expected the curse to appear. However, it had come from below, and Yuji was already in the air, quickly devouring the finger. For a moment, everything went silent as Yuji suddenly began to tear off his clothes.

"Shit!" Megumi cursed as they watched Yuji obliterate the curse with a swift wave of his hand. This made Aki even more cautious about Sukuna's power.

From the beginning, Aki had been wary of Sukuna, but he couldn't prevent Sukuna's incarnation.

It was the world's way of restoring balance in this era, with Gojo Satoru being untouchable and Aki Hayakawa capable of using cursed spirits and their techniques if he chose to. The power balance had been disrupted and needed something to mend it, and that was Sukuna's incarnation.

"Hahaha, keh keh, hahahahaha, heheheh! As expected! The sensation of flesh is delightful! I finally have a meat body to control as my own!"

The voice was unmistakably that of Ryomen Sukuna, the king of Curses, celebrating his successful incarnation.

He leaped onto the railing and let out a roaring delight, "Where are all the women? The kids?! What a delightful era to be in! They're spawning like maggots!" He laughed with excitement, while both Aki and Megumi remained frozen by the overwhelming potency of his cursed energy.

However, before he could proceed any further, a cursed spirit smacked him on the head with a staff it held in its hand. The spirit had a mask with eyes drawn on it.

It was a special-grade cursed spirit in a humanoid form, with an androgynous appearance. This spirit possessed the unique ability to turn invisible, only revealing itself when it attacked. Its expertise lay in infiltration.

This was one of Aki's cursed spirit, which he had exorcised and absorbed, gaining it as a potent ally. Despite its original role in infiltration, it possessed the strength and speed of a special-grade spirit.

Sukuna halted, and his hand was poised to use a technique when his other hand caught the one about to make the move. A look of confusion and surprise crossed Sukuna's face as he said, "What?"

A slightly different voice was heard as Itadori regained control and demanded, "This is my body. What do you think you're doing with it? Give it back."

As Sukuna was being suppressed, Megumi shouted at Yuji, "Under Jujutsu regulations, I will now exorcise the curse named Itadori Yuji!"

Before anyone could react, another voice reached their ears, "What's happening?"

"Gojo-sensei!" Megumi exclaimed as he saw his white-haired teacher standing there with a paper bag in his hands, "why are you here?"

"Oh, that. The higher-ups don't really give me any peace of mind. They kept nagging me about their missing special-grade cursed object, so I agreed to come as long as I get some time to sightsee," the white-haired man said with a silly grin on his face.

"But oh man, you're all roughed up. I have to show the second years!" He took out his phone and started taking pictures of Megumi quickly, with a silly laugh accompanying each shot. Megumi shielded his face from his Sensei's impromptu photoshoot with his hand.

Pausing after a few seconds of rapid photo-taking, he stepped back and looked at the three individuals, including the other people with Megumi.

He thought he saw a resemblance to his best friend in the black-haired kid and noticed a cursed spirit hovering behind them, further fueling his suspicions. Dismissing the thought for now, he turned to Megumi and asked once more, "So, where is it?"

"Um, sorry, but I ate it," Itadori said to Gojo with a silly expression.

"For real?" Gojo asked, perplexed.

"For real," all three voices echoed simultaneously.

Alright, you guys, I've decided to start a new fanfic. As you've read in the chapter, the fanfic's premise is Jujutsu Kaisen with an OC who's born as Aki Hayakawa from Chainsaw Man.

I believe I can handle Tensura: Karna and this. Writing two fanfics isn't easy, but I have the utmost confidence that I can deliver at least two chapters a week.

So, stay tuned!
