Author's note: This story is based on the Jujutsu Kaisen manga, which has some variations from the anime. If you find any discrepancy in the dialogues or scenarios, I invite you to investigate how it was in the manga. It is a story of short chapters, as I find it unnecessary to be a detailed episode (I don't know how to write long chapters)

-------------------------------------------------------------------------------------------------

Place: Japan, Miyagi District, Yugisawa High School.

A boy could be seen, muscular, with pink hair and bloodied.

What was this boy doing at this moment?.

He was eating a finger.

While being held by a huge creature, to the astonished sight of a battered black-haired boy. In a blur, imperceptible to many humans, including the so-called sorcerers of this world, Itadori; The boy. now with black lines all over his body, destroyed with one hand the immense creature that held him.

"Ah, I knew it! Light is the most appreciated flesh!".

The finger that Itadori ate was poison.

"The flesh of the cursed spirits is boring!"

It was the finger of a curse that ruled a thousand years ago, invincible.

"Women! Children! They reproduce like damn worms!".

It was Ryomen Sukuna, the King of Curses.

"IT WILL BE A MASSACRE!"

Itadori was peculiar, for several reasons; His pink hair, his strength… And a body conceived to be the container of Ryomen Sukuna.

"What do you think you're doing with my body? Give it back to me!"

Said Itadori as he took his own face, interrupting Sukuna's dramatic act.

"How are you able to move?" Sukuna was amazed and confused 'He is suppressing me' thought Sukuna.

For Itadori it made no sense what he was saying, It was his body, Obviously he could move it, it was his, Was he stupid?.

"Um… It's my body, you know?". Said Itadori, as if explaining something to a child.

"Don't move!" Interrupted the already forgotten black-haired boy "You're no longer human! According to the regulations of sorcery, Yuuji Itadori; Just like a curse! You will be exorcised!".

"Uh?" Itadori didn't understand anything."Calm down calm down! It's me, look!" The dark lines on his body began to fade "More importantly, shouldn't you go to a doctor? You got beaten up". Asked Itadori, worried.

'Is the curse speaking at this moment? Or is it Itadori… ? I wouldn't know' The black-haired boy didn't know what to do, Maybe he should invoke Mahoraga, just in case.

"What situation do we have here?" A tall man appeared, with white hair, dressed in black and a black cloth covering his eyes.

"What…?! Gojo Sensei! What are you doing here?!" Asked the novice sorcerer.

"Hey there! I wasn't going to come, but the big fish interfered when they heard that a special grade cursed object was missing. I agreed to come on the condition that they let me do some sightseeing." Answered the man.

"So…did you find it?" Asked Gojo.

"…" Megumi.

"Umm…" Interrupted Itadori "I'm sorry… I ate it" He informed, embarrassed.

"Ehh…? Really?" He asked for confirmation.

"Really" Reaffirmed Itadori.

Gojo approached Itadori, with curious eyes and long strides.

"You're right! They merged! How funny!" Gojo spoke as if everything was normal, as if nothing worried him, as if he had everything under control."How does your body feel? Can you switch with Sukuna?" asked Gojo.

"Fine, I guess." He replied "Sukuna?" Itadori asked next.

"The curse you ate" Said Gojo.

"Eh, Yeah probably" Itadori.

"Ten seconds, take control of the body again in ten seconds" Proposed Gojo

"I'm not so sure about this…" Itadori doubted.

"Don't worry, I'm the strongest sorcerer" Affirmed Gojo, with a confident smile on his face "Megumi hold this" Throwing a bag.

"What is this?" Questioned Megumi "Kikuifuku mochi" Confessed the white-haired man without shame.

."Did you buy souvenirs while people were in danger?!" Said Megumi.

"They're not souvenirs, I'll eat them on the way home" Responded Gojo as he stretched his legs and cracked his fingers, as if he was about to play.

Gojo turned around and began to explain "They're made of a sweet and soft dough-".

"Watch out!" Warned Megumi when he saw the blur of Sukuna attacking his master.

Everything was filled with dust, nothing could be seen, but Gojo's voice could be heard "Sweet and soft, filled with chocolate, a delight" And he continued describing what he was going to eat on his way home.

Megumi could see Sukuna's red eyes inches from him, and his teacher, Gojo Satoru, sitting on the king of curses, treating the king like a chair. 'No wonder he is the strongest sorcerer' was Megumi's thought.

Sukuna turned around, attacking with a swift slash at the human who dared to sit on his back, but he hit nothing, Gojo had dodged the attack and was now standing in front of him, observing him through that dark bandage.

The atmosphere changes, the air becomes dense, almost palpable, as Sukuna and Gojo face off. Gojo, with his characteristic bandage covering his eyes, stands firm and defiant. Sukuna, having taken control of Yuji's body, prepares to attack.

Sukuna, confident in his power, launches a fierce attack. But to his surprise, Gojo easily dodges his blows with supernatural speed and agility. It's as if he's dancing, moving with grace and precision around Sukuna's attacks.

"I'm going to show off a bit, my student is watching me" Gojo said, while dodging Sukuna's blows.

Gojo launches a series of bewildering attacks against Sukuna. Each blow is so fast and precise that Sukuna barely has time to react. Despite being the most feared curse, Sukuna is overwhelmed by Gojo's skill and power.

'He has inhuman speed' Sukuna thought

'No… it's something else' The King considered.

The fight intensifies, with Gojo launching a series of quick and precise blows. Sukuna tries to block and dodge, but each blow from Gojo seems to find its mark. Sukuna staggers, clearly surprised by Gojo's strength.

Sukuna takes a heavy blow that sends him flying, crashing into the railing behind him. "No matter what time we are in, sorcerers will always be a headache" Sukuna muttered dazed.

He quickly jumped up towards Gojo and gave his strongest attack so far, destroying a large part of a school area where they were, filling the building with dust again "But they will only be a small headache…" Sukuna said to himself, confident in his attack.

"7…8…9". The dust dissipated, revealing Gojo unscathed and Megumi behind him, injured and battered, But he was already like that. "10" Satoru finished.

Beat Beat "Who is… this… Itadori?" Sukuna murmured sleepily before losing control again.

"Hey! What's up!" Itadori raised his hand, greeting. Gojo approached him, amused. "Heh, So you really have control over Sukuna" He said humorously. "Yes, but it's a bit annoying" Responded the now vessel of Sukuna. "It's a miracle that's the only side effect" Gojo said, now in front of Itadori, he placed his fingers in the center of his forehead Tap, giving him a little tap on the head.

Itadori proceeded to collapse in front of Gojo, being held up by him.

I know it's a short episode, but it's the prologue and I don't feel it's necessary to present the situation as if no one has seen the anime. It will be a short Fanfic with several time jumps, as an author I write the stories that I like as a reader.
