Hajime Kashimo

Under the glistening sun, the streets of Kyoto, Japan could be seen filled with people walking back and forth as they went on their day.

But on one of the buildings on the roof, a white-haired person could be seen, wearing a full white outfit with a bo-staff hanging over their shoulder as they sat at the edge of the roof, watching the passerbys.

[Insert Picture of Hajime Kashimo]

"Don't they get bored of such a life?... Well I suppose they don't have a choice." Kashimo muttered as he watched people going to work.

He then became lost in his thoughts as he pondered on how he reincarnated in the Jujutsu Kaisen world over 3 years ago. His first train of thought was denial, but soon realized everything was real as he himself had powers of that a sorcerer.

Once he grasped his situation, he didn't hesitate to enjoy his new life as he started doing sorcerer work, exorcising curses, which gave him a certain thrill.

But his new body didn't have a job, home or food, so he had to resort to stealing.

And over time, he was noticed by Jujutsu Sorcerers, and the one and only Satoru Gojo offered him a job as a sorcerer which included him teaching Kashimo how to use his powers.

In the past 3 years, his talent was seen as of a genius and quickly became a Special Grade Sorcerer, considered as the upper-echelon of Jujutsu Sorcerers.

Kashimo shook his head with a smirk, "To think I would reincarnate into such a world... Well time to go back." He abruptly stood up and started running across the roofs of buildings, heading back to Jujutsu High.

Sparks of electricity could be seen at the soles of his feet, as his speed seemingly increased and he disappeared like a blur.

Today was his first day back in Japan and it had been over 1 year since he trained overseas by himself, he made sure to come back around the beginning of canon, just in case anything unexpected happened.

As trails of lightning could be seen behind him as he sped across the buildings, he felt his phone vibrate from his pocket, causing him to stop.

Taking out his phone and answering it, he heard a familiar voice, [Yo Hajime!]

Recognizing the voice, Hajime couldn't help but grin, "How's it been Gojo?"

[Haha! You already know how tiring it is to deal with these higher-ups on a daily!] Gojo chuckled as he replied.

Kashimo nodded as he continued to speak, "Seeing as how you called, do you need something?"

[I need a favor, I heard you just came back and I need someone to watch over 3 first years, I'll only be gone for a few days.] Gojo explained.

Kashimo seemed to understand the situation as he asked, "Does this have something to do with Sukuna's vessel, Yuji Itadori?"

"Hmm?... How do you know about that?" Gojo questioned curiously, his tone slightly becoming darker.

Kashimo shrugged, "Let's just say I have a good information network."

[I see, well I'll be sure to remember that if I ever need information... So can you do it?]

Kashimo wasn't avid about babysitting, but he was curious about how the main characters of the story were like in real life, so he agreed.

"Sure, I gotcha."

[Perfect! I'll send you the list of their information, call me if you need anything!]

"Alright." Kashimo simply replied as he ended the call.

He continued running, and after a dozen more seconds, he swiftly arrived in front of Jujutsu High and entered the barrier.

Kashimo looked around with nostalgia, before finally stopping in front of a certain Japanese building, entering the building, he walked through the hallways before knocking on a wooden door.

"Come in."

He heard a voice from inside the room, as he opened and entered.

Inside the office room, was a brown-skinned man in sunglasses with brown hair, sitting behind a wooden desk.

"Kashimo!? Your back early..." Principal Yaga's eyes widened under his glasses as he saw Kashimo's figure enter casually and sit down in front of his table.

Kashimo shrugged as he replied, "Got bored I guess... I came here to check in."

Principal Yaga nodded as he pulled out a clipboard and gave it to Kashimo who swiftly signed it.

He didn't even wait as he stood up and was about to leave.

"Where are you going?" Principal Yaga questioned with a raised brow.

"I have some kids to babysit." Kashimo didn't attempt to explain as he simply walked out.

As Kashimo walked through the empty hallways, a certain student entered his vision from down the hallway.

Once they got closer, the girl had dark green hair and glasses on, with the Jujutsu High uniform.

Kashimo recognized her and had a coy smile on his face as they walked past each other.

She stared at him weirdly, before continuing to walk.

Until suddenly her instincts flared in danger, she swiftly turned around and quickly sent out a punch.

Bam!

Her eyes widened as her fist was stopped by a palm.

'What the hell!?... It felt as if I punched a steel wall!' She exclaimed inwardly.

"My, my, why don't you calm down?" Kashimo slowly lowered his palm as she did the same.

"Then you shouldn't direct your killing intent like that!" The girl angrily replied.

Kashimo ignored her as he continued to speak, "You must be Maki Zenin, the girl who has no cursed energy and is shunned by her clan."

Maki frowned at his words, "What's it to you!?"

Kashimo got closer to Maki's face as he whispered, "If you want, I can slaughter the entire clan for you."

Maki's eyes widened as she backed up, "W-What are you talking about!?"

He had a wide smile as he continued, "Well I can't believe they would shun such a pretty girl like you... Say the word, and I'll completely decimate them."

Maki was flabbergasted as she backed up warily, wondering what his intentions were.

Silence ensured for a few seconds until Kashimo chuckled.

"Just kidding! Well, I have somewhere to be." He patted her shoulder before turning around and walking down the hallway.

Maki sighed in relief, 'He didn't seem like he was joking, who the hell was he?'

She knew he was probably a sorcerer since he just left the Principal's office but couldn't recognize him.

Maki was about to continue walking, until it dawned on her, 'White hair in two bundles?... Blue eyes? A bo-staff hanging on his back?... Hajime Kashimo!'

Everything came together as she recognized his description.

She knew he was a Special Grade sorcerer, but he rarely met with people and only hung out with a certain few people.

Shaking her head, she simply opted to continue walking as she had to train.

****

Kashimo could be seen stopped in front of a wooden door as he slid it open.

This was the 10th door that he entered, but he kept going to the wrong room, he realized he probably should have asked Principal Yaga for which room they'd be in.

But once he entered the classroom filled with desks, only 3 students could be seen.

One young man had raven-black hair, the girl had brown hair and the other guy had pink hair, all were wearing Jujutsu High uniforms.

"Megumi Fushiguro? Nobara Kugisaki? And Yuji Itadori?" Kashimo questioned as he stood in front of the podium and relaxed on it.

"Here!" Itadori raised his hand happily as if he was a student, while the other two nodded with neutral expressions that seemed bored.

He felt his phone vibrate, so he checked his phone real quick, before looking back up to the 3 students.

"Well, it seems I'll be supervising over you guys for now! And it seems we already have a mission! So chop-chop and follow!" Kashimo clapped his hands and left without waiting.

The three students were stunned, before quickly following after him.

After they traversed the wooden hallways, they finally were out of Jujutsu High, and a black sedan could be seen waiting with a man in a black suit standing in front of it.

"If it isn't Ijchi, Gojo's assistant!" Kashimo greeted with a slight wave.

Ijchi seemed to have a tired expression as he greeted back, "Nice to see you too."

Kashimo nodded as he glanced behind him at the three students, "Get in the car, he'll drive us to your mission."

The other three nodded as everyone got in the car.

While Ijchi was driving, Nobara decided to ask a question.

"Are you a man or a woman?" She questioned blatantly.

'Can't she just keep her mouth shut.' Megumi inwardly thought as he glanced beside him.

Itadori just had an awkward smile as he decided to stay silent.

Ijchi seemed too tired to even react as he continued to drive.

Kashimo turned around from the front seat and laughed, "I'm obviously a guy!"

Itadori raised his hand, seemingly wanting to ask a question, Kashimo nodded in confirmation.

"What's your name?" He asked curiously.

"Hajime Kashimo, but you can call me Kashimo!"

Megumi's eyes widened, "Wait... Are you the Special Grade Sorcerer Kashimo? The one rumored to have defeated over 1,000 curses in one night!?"

Nobara and Itadori couldn't help but have bewildered expressions as they heard what Megumi said.

"Oho! Am I that famous!?" Kashimo sarcastically remarked.

A bead of sweat could be seen on the side of Megumi's forehead, 'From what I've heard, he acts more like a criminal rather than a Jujutsu Sorcerer... But no matter how eccentric Gojo may act, he wouldn't put us in the hands of someone irresponsible.'

The rest of the ride was silent until finally stopping in front of a school building.

Once they all exited the car, Ijchi explained the mission to them and the three 1st year's started walking toward the school.

But Itadori glanced back once realizing Kashimo wasn't moving, "Aren't you coming Kashimo?"

"I'll be watching over you guys from afar, I'll make sure none of you die!" Kashimo suddenly proclaimed as he disappeared in a flash of lightning.

"Is he serious?" Megumi grumbled.

Itadori seemed to be the only one with determined eyes, "Gojo-sensei and Kashimo must trust us to do our own mission! Lets prove them right! Come on guys!" He then started walking toward the school.

"Let's show them what we're made of!" Nobara grinned as she followed behind him.

Megumi seemed to be the only one hesitating, "I have a bad feeling about this..." He muttered but nonetheless followed after them.

They then investigated the school building, finding some dead bodies.

The 3 of them ended up in a large stone room, where Megumi and Itadori were arguing about saving lives.

They started getting physical as they grabbed each other's jackets, glaring at each other.

"Cut it out guys! We don't have time for this-"

Nobara suddenly stopped talking as something pulled her into the ground.

Itadori and Megumi's eyes's widened as they glanced toward Nobara's previous position, but before they could say anything else, their senses started ringing with danger.

They were both frozen in fear as their eyes slowly looked back to their left...

A cursed spirit with four eyes and grotesque facial features, wearing nothing but some black pants, menacingly stared at them as he was only a foot away from them.

Itadori immediately reacted as he swung the blade in his hand toward the cursed spirit's head.

Swish!

Itadori and Megumi looked toward his hand which was missing, in shock.

Spurttt!

Blood sprayed out of the missing stump of his hand, causing Itadori to scream in pain.

"Aghhh!"

"Itadori!" Megumi worriedly called out as they both hopped back.

Itadori gritted his teeth as he tied a piece of cloth around his missing hand.

"Fushiguro! Leave and go find Kugisaki! Once your outside, send me a signal and I'm going to switch with Sukuna!" Itadori hurriedly explained.

"You know you can't do that!" Megumi retorted.

"I can at least stall for time!... Please Fushiguro." Itadori pleaded as he looked toward Megumi with a calm smile.

Megumi couldn't help but curse as he turned around and started running away, "Stay alive!" He exclaimed before disappearing into the hallway.

Itadori focused back on the curse as it swung it's arm forward toward him.

Boom!

A large wave of curse energy crashed into Itadori as he slammed into the wall behind him.

'What was that!? A cursed energy barrier?'

Unfortunately, Itadori couldn't finish his thoughts as the cursed spirit instantly appeared before him with their fist enveloped in an orange hue of curse energy.

Boom!

The cursed spirit punched Itadori through the wall and sent him flying into the ground of another stone room.

The monster then hopped through the hole in the wall and landed in front of Itadori.

Itadori slowly got up as he warily watched the monster.

The cursed spirit spread its arms out and released a large wave of cursed energy in all directions.

Itadori raised his arms out and pressed them forward as he tried to defend himself.

"Ahhhh!" He screamed as he was slowly pushed back and his fingers were being disintegrated against the cursed energy.

His life flashed before his eyes as he thought of everything he's been through.

He wondered about giving up...

But then the wave of cursed energy overpowered him and he only had one thought in his mind before he was enveloped.

'Have I become so weak?'

He questioned before everything went black and he was tumbling into the wall.

After a few seconds, he regained consciousness and he thought back on his life once more.

All the memories of his life caused to make him remember that he can't give up now, after all he's been through and decided.

Itadori slowly got up and watched as the cursed spirit seemed to be laughing at him and dancing all over.

Once he was standing up, his eyes were determined as he launched himself at the spirit and sent his most powerful punch that was enveloped in cursed energy directly at their face.

Bam!

Itadori's eyes widened as his fist was caught in their palm...

Wooo!

Hearing a howling wolf in the distance, which seemed to be Megumi's signal that they left the building.

Itadori closed his eyes and slowly two other eyes appeared with markings on his face.

"What a thoroughly annoying brat." Sukuna muttered as he took control of Itadori's body.

"He's obviously screwing with me."

Sukuna continued to murmur to himself as the other cursed spirit backed up warily and seemed to be shaking in fright.

He abruptly started walking away and told the cursed spirit to follow him, but then he felt a surge of energy as he turned around and raised his missing hand which healed.

Boom!

"Idiot." Sukuna stated as he blocked the beam of energy that was from the cursed spirit.

After a minute of fighting, Sukuna easily defeated the cursed spirit and devoured his finger.

Sukuna quickly noticed that Itadori couldn't take control back so he decided to leave the building and go for his friends.

Stepping out into the rainy atmosphere, Sukuna suddenly disappeared from his position with a grin.

****

Megumi could be seen standing out in the rain, waiting for Itadori to come back and if worst came to happen, he was prepared to fight Sukuna also.

His eyes locked onto the school as he felt something change, 'The Innate Domain's closed off! That means the cursed spirit is dead... Now all I need to do is wait for Itadori.' Megumi thought inwardly.

Megumi's eyes widened as he felt a presence standing directly behind him.

"Sorry, but he's not coming back." Sukuna spoke with a calm smile as he walked in front of Megumi, before ripping off his shirt.

"It seems that brat is having trouble switch bodies." Sukuna explained condescendingly.

Megumi clenched his fists as he watched Sukuna cautiously.

"So I thought what I could do while I'm in control." Sukuna pointed his hand toward his chest and attempted to pierce it until a hand grabbed his wrist.

"I was content watching because they need the experience, but it would be a bit troublesome if you pulled out his heart." Kashimo suddenly appeared beside Sukuna with a smirk.

Sukuna's eyes widened, 'Fast! I didn't even sense him... And his grip seems to be rather firm.' Narrowing his eyes, he could tell the person in front of him was no small fry.

Swiping his hand away, he pulled his hand out of Kashimo's grip, or rather Kashimo simply let go.

Grinning, Sukuna spoke, "You Jujutsu Sorcerers' arrogance never changes!"

Kashimo simply ignored him as he looked toward Megumi, "Megumi you alright?"

"Y-Yeah." Megumi absently nodded, the amount of relief he felt with the appearance of a Special Grade Sorcerer could not have been described with words.

"You can watch this fight, but call Gojo while your at it! Inform him of this situation and tell him the most likely cause is the higher-ups." Kashimo winked before approaching Sukuna once again.

Even though it seemed as if Kashimo wasn't paying attention to Sukuna, his focus was solely on him in order to make sure he doesn't try to kill himself again.

"So where were we again?" Kashimo had a light smile on his face as he stood face-to-face with Sukuna.

"We're at the part where I teach you a lesson, you damn punk..." Sukuna had a battle-thirsty smile as they gazed at each other.
