Jujutsu Kaisen: No Regrets

Cursed Energy was a strange concept.

Unlike other fictional types of energy such as Reiryoku, Haki, Chakra or Ki, cursed energy had an additional level of complexity.

Itadori vaguely remembered Gojo's explanation in the original storyline, where he compared cursed energy to electricity.

He couldn't say if that was the best comparison to use for this energy, as even though he the anime and manga, he didn't put much attention into such details.

To put it in simple words, he understood how the energy theoretically worked, though it take him some considerable time to manipulate it.

In his previous life, he was a talented guy, quite intelligent for his age, but that was far from enough for him to control this type of energy in just one day.

It was still a concept too new for him, no only controlling the energy in his body, but also controlling his own emotions, all done simultaneously.

Cursed Energy, reverse cursed energy, cursed techniques.

Which were although originated from the same energy, had different purposes and works.

Understanding all this in a day was far beyond his capability.

"..."

Sitting on the chair of his new dormitory, Itadori closed his eyes and tried to feel cursed energy within him with a troubled look.

But that didn't mean he couldn't try.

Even if he couldn't control it, the least he could do was to discern the energy flowing through his body.

Suddenly, he felt a new strange sensation coursing through his body. He could feel it. It was cursed energy.

Since swallowing the second finger of Sukuna, he had been able to feel this strange sensation, as if something being pumped from his torso to the rest of the body.

He tried to manipulate it a few times since he acquired it, but it felt as if he was just peeling off his own skin with own hands.

Maybe during combat, he could gain a better understanding of it, but until then, feeling it was all he could do.

!

"What?! It's really there. Sukuna's third finger is already present inside my body."

Itadori looked surprised when he decided to feel the cursed deep inside his body. It was something he always suspected while watching the anime and manga.

Why was Itadori physically gifted so much? Even if it meant because of existence of Kenjaku, he was still intrigued by the fact that Itadori was physically strong.

The best theory would be, during Itadori's birth, Kenjaku must have sealed one of Sukuna's finger inside Itadori. It was a theory that made sense and he always suspected.

He tried to feel the energy from the finger. But he couldn't do it as he could do it to the other fingers that he swallowed.

"I can't control it. It must be in a sealed state. Then I must unseal it and use the power for my own use."

Itadori frowned as he said about it. But he started to meditate with sheer determination and willpower. As he knew that emotions could help him manipulate cursed energy.

And he was right, by setting his goals higher and with persistence, he could go beyond the limits of his body. It was something, that could only be applicable in a fictional world.

With a strong emotional stimulus, he subconsciously broke through the bindings that disabled him from using cursed energy. He felt a lingering sensation developing within him.

He broke through the state and was finally able to unseal the finger and felt cursed energy even more deeply. He tried to gather cursed energy around his fist.

The concentration of cursed energy deeped and he could feel a strange energy around his fist.

"Yes! Did it!"

Itadori opened his eyes and shouted with joy as he looked at his fist. Enveloping it in cursed energy, though it was little in amount, it was still a progress.

Slam!

"You idiot, don't shout! I'm trying to sleep!"

Megumi who was the next room to Itadori, as he was about to sleep and heard his scream. He entered Itadori's room with the door slamming.

"Okay, okay. I'll take care. Don't worry. Go to sleep."

Itadori wavered his arms and said while giving thumbs up and smiling.

Fushiguro noticed a faint source of energy coming from Itadori's fist as it disappeared a moments later.

Fushiguro returned to his room and thought about. It was undoubtedly cursed energy as he vaguely remembered the sensation.

'Did he used it this early? Cursed Energy?'

He thought as he sighed.

Itadori in his room tried to recreate the cursed energy and kept on practicing while using it on his body, to reinforce it. He felt light and could do movements with ease.

In that sense of accomplishment, he felt proud and did excercises like push-ups, pull-ups, curl-ups, sit-ups and squats. He also ran around like crazy, around the whole campus.

Gojo noticed Itadori running around and gave smile.

'Well... That's what to be young.'

He thought inwardly.

[The next day]

"When is Gojo sensei coming?"

Somewhere in Harajaku district, Itadori asked Fushiguro, while licking his ice cream.

"Don't know. That guy is always late."

Fushiguro said while not giving much thought to Itadori's words.

After a few moments, they looked at girl arguing with a man. She was in a mess. He was trying something to prove the man wrong. She was of a shot stature with brown short hair.

She wore the Jujutsu High School uniform.

"Fushiguro, is that her? The new first year, we were supposed to meet?"

Itadori even knowing, just questioned Fushiguro while pointing at the girl.

"Look's like it."

Fushigro answered while looking at her.

"Hey,! I asked you to wait for me!" Both the youngsters looked behind them. A man approaching towards them while waving his hand. It was none other than Gojo.

"Oh... Looks like she's here." Gojo, after reaching Itadori and Fushiguro looked at the girl arguing with a man.

"Oi! Over here!" Gojo waved his hands as he called over the girl.

_ _ _

[A few moments later]

At a nearby place she kept belongings inside a locker.

"Let her introduce again." Gojo said once again while pointing at her again.

"Kugisaki Nobara. Be happy boys. I'm the only woman in your group." The girl said while looking at the guys.

"Itadori Yuji from Sendai." Yuji said while pointing at himself, with a calm demeanor.

"Fushiguro Megumi." Megumi said, looking uninterested.

Kugisaki stared at both the guys and assessing their looks.

"Sigh... I am only one getting my involved in unfortunate circumstances." The girl said while looking disappointed.

'What was she expecting?' Yuji frowned at the thought.

"So, where are we going?" Megumi asked.

"Where else. We're going on tour to... Tokyo!" Gojo said, while giving a bright smile.

"Tokyo! Tokyo! Tokyo! I love Tokyo! TDL! I want to go TDL!" Nobara jumped around in joy just by listening the name of Tokyo.

"I will tell you, where we are going."

"Roppongi!"

Gojo said, while also celebrating with Kugisaki.

Yuji and Megumi maintained their distance from Nobara and their teacher.

"I bet something is wrong with their heads."

Yuji pointed at Gojo and Kugisaki as he spoke.

Megumi sighed and nodded in reply.

A few moments later, they had arrived at their destination.

They stood outside an abandoned building exerting cursed energy from curses.

"There's some curse here." Gojo said while looking at the abandoned building.

"You liar! This isn't even Roppongi! You were toying with a country folk like me!" Nobara screamed as she looked annoyed.

"There's a big cemetery nearby."

"The double whammy of that and an abandoned building brought out few curses."

Gojo explained the situation.

"I want to know what you guys are capable of. Just think of this as a field test. Nobara, Yuji, you two go inside and exorcise the curses inside the building." Gojo said while looking at the building.

Gojo walked towards Itadori and took out something from his jacket.

"Yuji, you use this. Since, you have very low cursed energy. It's the cursed tool, Slaughter Demon. It'll work on curses too." He handed out the weapon to Yuji.

Yuji unsheathed the weapon and looked at blade, somewhat similar akin to a knife.

"Oh... By the way, I wanted to ask something. How does your uniform feels?"

Gojo asked.

"It feels okay. Perfect size. But why is different from Fushiguro's?" Even knowing the answer, Yuji still asked.

"Well, sensei has got a knack of doing this sort of things."

Megumi spoke out of frustration.

"Hehe."

Gojo simply laughed it out.

Yuji and Nobara readied their gears and started walking towards the building.

"And Yuji! Make sure you don't let Sukuna out."

Gojo said with his signature smile.

"Don't worry about it. I won't him out."

Yuji said while giving him a sign of approval.
