Technique

'Where do I go?'

Shiro was now in a large mountain, that was covered with trees. He had just finished sleeping.

Although seeing a baby walk around, with red eyes and a black sclera would definitely be an odd sight.

'Being a baby... Sucks.'

Shiro decided to spend some time on the mountain training. Within a few years he estimated he should be able to train his body to an acceptable level.

'Hmm?'

As Shiro thought he could feel something within him.

'Cursed energy...'

Quite possibly due to Shiro's nature as part cursed spirit he felt an energy swirling within him. This energy was quite large...

Shiro then sat down and meditated. His first goal would be to control this energy and try to preform whatever technique he could. He would have to experiment a lot for that...

'This is going to be a long time...'

***

A young figure, the age of 2 stood still in a forest.

'Baby life still sucks...'

Shiro stood still. His naked body exposed to nature. He had been training at a great pace, mainly due to his heling speeding up the process of muscle growth.

He currently looked like a ripped and muscular baby. Quite the odd sight.

However there was something greatly annoying Shiro at this moment.

He was growing no hair... At this rate he thought he would end up like a certain caped baldy.

Ever since the massacre he had also tried controlling the cursed energy in his body. He found the energy rather easy to control, possibly due to his heritage and he was currently eager for his innate technique.

Innate techniques usually awakened at the later age of five or six, but Shiro could feel that it was coming soon. Possibly in a year or two.

***

'Wait... What day is my birthday?'

Shiro was now the age of 3. He had found himself tallying each day using a large stone to record the days passed.

Shiro's progress had unfortunately stagnated greatly.

Without proper guidance on the use of cursed energy or a way to use techniques Shiro was at a standstill.

He had also stopped his training for a few months to figure out if his hair was actually going to grow...

Anyways Shiro felt rather excited as this would be his first time using a supernatural power like he had originally envisioned.

While he loved martial arts, he currently felt like Yujiro. An apex in the aspect with nobody to challenge him.

From Shiro's view the Jujutsu Kaisen world had not particularly developed it's martial arts to a level of Baki's world. In fact nowhere near the level...

But Shiro would welcome any surprises as a different world's martial arts might be... Different.

'I guess I will be bald for this life.' Shiro rubbed his shiny head as he thought, and started his training.

***

'Finally!'

Shiro had finally acquired his innate technique, at the age of 5. Honestly, Shiro was going rather crazy as he was isolated and stuck in this forest.

The only thing relieving him of his boredom was making random structures out of the materials around him, or training his cursed energy and martial arts.

He did take an odd hobby however. In his previous life he used to watch a video on youtube where two guys made swimming pools, or underground houses...

Shiro raised his palm as he started to manipulate his cursed energy. This would be his first time using his innate technique.

Nothing happened...

'What?' Shiro was shocked. His innate technique did... Nothing?

Shaking his head slightly he tried to use it again, this time aiming at something.

No sound was made. But something that made Shiro's eyes expand happened.

The rock completely disappeared. Shiro rushed towards the place, to check if it was an illusion or something similar, but as he arrived in the rock's place...

'It's actually gone...' This ability seemed rather overpowered... Shiro excitedly acting like a kid found a new interest.

He executed his technique again, this time at a tree.

As it was executed Shiro felt odd... The technique didn't work and he could feel something rushing up from his mouth.

*SPURT*

Shiro spat a large amount of blood onto the ground. It seemed that he was too excited and didn't realise how much cursed energy it took from him.

When he executed the technique he simply didn't have enough and received backlash. Luckily he had his healing, because if he didn't he would be seriously injured.

Taking this as a lesson Shiro sat down and meditated. He needed to clear his thoughts and become calm. Only then would he practice his technique again.

***

'Delete'

A bald and naked figure stood in a forest. As he stood, a large tree in front of him disappeared out of existence.

This was Shiro. He was now 7 years old and had experimented with his technique quite a lot. He figured out that he couldn't use it on animals, and guessed that it would be the same with humans or cursed spirits.

He also figured out that the some things took more cursed energy than others. For example a rock took much more cursed energy than a tree.

Shiro had also developed a simple application for his technique.

It allowed him to coat parts of his body with a slight black aura that held the properties of his innate technique, allowing him to delete anything that it touched.

It needed to be modified and was a rough technique. It also took heaps of cursed energy and wasn't really combat ready.

But with the addition of this he could be called a sorcerer hunter. Though he didn't know how much cursed energy it took to delete a technique.

He now had relatively high cursed energy. Enough to delete dozens of rocks and trees, but he hadn't tried much of anything else yet.

He had also confirmed that he would be forever bald. However this could be beneficial as the shine could distract enemies mid-fight.

Shiro rubbed his head in a state of reminiscence...

'I miss my hair.'

***

Shiro walked carefreely in the streets. He wore some black pants and a basic white shirt, which he kindly took from a store...

As he walked he conjured odd stares...

He was now the swift age of 17. He looked rather handsome his shining bald head reflected the sunlight and his ripped body could be seen through the shirt.

However what was odd, was the black sclera and red iris he had.

"Hey... You think he is one of those cosplayers?" As Shiro was walking, a few kid's looked at his eyes...

"He's weird... We should probably stay away from him."

Shiro had noticed the odd stares and didn't care. Humans tend to fill in the gaps for you if they don't understand something, and who would think that a 17 year old kid is a cursed spirit?

'Hmm?'

As Shiro walked with no goal in mind he picked up a spike of cursed energy. He snapped his head in the direction as he moved towards it.

'These should be sorcerers right?'

Shiro sprinted as fast as he could. This would be his first interaction with someone that hopefully doesn't want him dead.

It only took a few minutes to get to the location as Shiro's current strength was rather good.

'Is that... Gojo?'

Reaching the location he saw Satoru Gojo, a white haired man who is the strongest sorcerer alive.

He also saw two women. One he recognised as Mei Mei, a pale blue haired woman that he saw in the manga once. But the other one he did not recognise. She had long purplish/blackish hair and wore a Miko outfit.

There was also another woman with short brown hair and brown eyes. This woman he recognised as Shoko Ieiri.

*BOOM*

A cursed spirit rose from the ground behind the girl Shiro didn't know. Shiro sat silently observing.

*BOOM*

Another cursed spirit that looked like a huge worm rushed out of the ground, eating the cursed spirit that was behind the woman.

'Suguru Geto'

Geto was a soon to be antagonist in the series. And that's pretty much all Shiro knew about the man. He had briefly touched upon the world but never delved too deep into it.

The group started chatting to each other as another girl joined in.

As the chatter came to an end Gojo turned his head in the direction of a shadowy corner.

"Now then. Let's see who is spying on us." Gojo said with a smile.

The girl in a Miko outfit was visibly frustrated when she heard Gojo say this, "This is all your fault!! You should have put up a curtain."

She crossed her arms as she stared vigilantly at Gojo.

"Okay calm down Utahime. I'm sure whoever it is won't be much of a problem." Geto spoke seemingly arrogant. But with the strength of this group combined it was very much the truth.

"Come out!" Gojo shouted.

Shiro hearing this flickered from the shadows and arrived in front of the group.

"Cursed spirit!" Utahime pointed her hand at the bald man. She had noticed his eyes and although it wasn't correct to call Shiro a cursed spirit, it was half right...

Gojo stood calmly. He observed this bald man... Being able to hide that well, and a large build-up of cursed energy was inside of him.

"The name is Shiro." Shiro said with a smile. While he didn't plan to make friends with this group, his goal was right in front of him.

He wouldn't miss this chance to test his current strength.

"Pfft-" Gojo laughed at Shiro's figure. He had tried keeping his composure but that bald head was really shiny...

Shiro watched calmly. He knew that getting angry over such a thing is worthless... Shiro stepped forwards, "Let's fight."

Gojo calmed himself as he watched Shiro smile slightly.

"Everyone step back." Gojo said.

"Gojo. Don't underestimate the bald spirit." Getou smirked as he said this...

Mei Mei had an amusing smirk on her face, as she silently watched.

Shiro and Gojo stood a few metres apart from each other. Gojo quickly set up a curtain to stop any normal people from seeing what is about to occur.

"Baldy. Show me how strong you are!" Gojo had been very bored. But this bald spirit might relieve him of his boredom.

Shiro didn't speak, as he would provide some punishment during this fight.

Shiro dashed towards Gojo and jumped in the air, just enough to preform an axe kick down onto the figures head.

"Interesting!" Shiro's foot had stopped mid-air as he was about to hit Gojo. This was one of Gojo's techniques called limitless, which included using his six eyes.

"Is this all baldy?" Gojo enjoyed annoying this person. Every time he did he could see a visible twitch.

However Shiro knew that this was the hidden inventory arc that was shown in Jujutsu Kaisen. Gojo, currently couldn't use his technique red or use limitless automatically. He couldn't even use the reverse cursed technique.

Shiro moved backwards before smiling maniacally... While he ignored the bald remarks, he definitely didn't like them.

He quickly rushed towards Gojo and...

'Delete' He used his technique to delete a very small part of Gojo's limitless. The hole was the size of a finger nail, but this was enough...

'Pierce'

Shiro used his finger and thrusted as far as he could towards the gap he deleted.

*SHOOOSH*

A torrent of air flew onto Gojo's face as his head snapped backwards.

The attack was rather weak as Shiro only used his finger but this should be enough to make Gojo serious.

Gojo spit out blood from his mouth and some dribbled down his chin...

Geto was about to speak but Gojo quickly raised his hand, stopping him. he turned towards the baldy, that had moved backwards.

"What did you just do?" Gojo smirked crazily... Someone had managed to crack his limitless technique. Although it only opened a gap for a few seconds and the gap was minimal in size, this man had managed to injure him.

"Beat me if you wanna know." Shiro said. Gojo should have a time limit on how much he can use limitless. If he uses it too much without the reverse cursed technique he will have his brain fried.

"Wow!! The bald one is winning." Utahime was enjoying Gojo being injured. He was a real pain sometimes...

"Impressive." Geto said, "Are you truly a cursed spirit?"

While Shiro had a black sclera and red iris, he looked completely human.

Shiro continued to look at Gojo, but he still answered, "I'm pretty sure I'm human as I came out a womb." He decided not to tell them about his current status. If he did he may be hunted for experimentation...

The white haired man looked at baldy trying to figure out if he was lying or not.

"Hey, wanna become a sorcerer?" Mei Mei asked. A talent like this was not something that should be let go of. Gojo was currently absorbed in his thoughts and wasn't speaking.

"If this idiot beats me then sure. Also if I win then he must become bald." Shiro smiled. He wanted Gojo to fight seriously.

"What!?" Gojo snapped out of his thoughts as he heard this.

"Sure! That would be quite interesting." Mei Mei stood inquisitively. It's a win either way...

"Better not lose Gojo." Although a bald Gojo would be interesting, Geto wanted this man as an ally. Any new sorcerer is needed to fight for the people.

"Shiro." Gojo's voice sounded as he seemed serious. "I won't hold back."

Shiro smirked as he stood in a stance. His bald head shined and his unique eyes looked intimidating.

Gojo raised his arm as he pointed it towards Shiro.

*BOOM*

A blue orb sped towards Shiro at a fast speed. A gravitational force pulled him towards it as he tried to move away.

'Delete' Shiro tried to use his technique, however the gravitational force only lessened a small amount.

But this amount was enough...

Shiro quickly tore off his arm and his leg, decreasing his weight just enough to spring off the ground and escape the force...

*CRASH*

He watched as the blue orb continued to slam into a building demolishing it insantly.

'I could have died just then...'

Gojo had just used his cursed technique blue. Normally if it came into contact with any normal person it would implode their body instantly, however Shiro was able to endure it long enough to escape.

As the spectators were about to open their mouth and rush towards Shiro, they noticed something.

His missing arm and leg were healing at a rapid pace.

"Reverse cursed technique..." Geto mumbled. This man was starting to look like a treasure in his eyes...

"Impressive..." Gojo wanted to test this man and if he died then... He was simply weaker than he thought.

Shiro had finally experienced the feeling of being weak again. But this didn't discourage him. Instead he had a new goal...

He was going to become the strongest sorcerer, and make Gojo bald.

'Void State'

Shiro's iris turned silver as he disappeared from Gojo's view.

*bang*

Shiro roundhouse kicked Gojo's side as he appeared behind him in a flash. Gojo had stopped using his limitless as it required manual attention and he had underestimated Shiro's speed.

Shiro followed up on Gojo as he kneed his stomach and delivered a barrage of punches, before his fist halted. A sign of limitless.

Blood trickled down the white haired man's mouth as he was inflicted some heavy damage from that combo.

This was only possible due to him underestimating Shiro. In fact he could capture Shiro's movements using his six eyes, but failed to react...

Gojo preformed a front kick as Shiro's punch was stopped by the limitless. Shiro was currently nearly out of cursed energy, so he couldn't delete the limitless anymore. Even if he did, Gojo would be expecting it and it would only last a few seconds.

Shiro stepped to the side as he dodged the kick and countered with his own. He aimed to kick Gojo's outstretched leg, but it was halted by the limitless.

The two fighters were at a standstill. Gojo's main weakness was close combat, but with limitless he could defend perfectly. Shiro could dodge Gojo's attacks and counter attack but with limitless...

The two fighters jumped backwards creating some distance. They both smiled as they knew what was coming next.

A small aura appeared onto Shiro's hand. This was his application of his innate technique.

Gojo raised his hand intending to preform another cursed technique blue...

The tension raised, but as they were about to attack, "Stop!" Geto intervened. This fight had to end here, as it would probably end badly...

"Gojo wins." Mei Mei followed up and announced.

Gojo and Shiro lowered their guard and techniques in tandem. Gojo smiled as he knew the outcome. Shiro, although annoyed by the loss knew he was going to lose. Even if he managed to use his technique he would receive backlash...

His cursed energy reserve depleted at an abysmal pace trying to nullify Gojo's techniques.

"You did better than I thought baldy!" Gojo lightly laughed. He may have been injured but he was still the strongest.

"Your not so bad... And stop calling me that!" Shiro would have his revenge later...

***

"So who is this? And what's up with the weird eyes?" Masamichi Yaga was sat down with his three students being Gojo, Shoko and Geto.

He had planned to scold Gojo for not placing a curtain and explain some things to him, but unexpectedly they brought a random person.

"This is someone with high potential. He managed to fight Gojo, nearly to a draw." Geto decided to get straight to the point. "His cursed technique allows him to delete things..." Geto then looked at Shiro briefly and muttered, "Very taxing however..."

Masamichi Yaga's face lit in amazement. This innate technique seemed like a cheat. He looked towards the bald man as he spoke, "What is your name?"

"My name is Shiro. Just Shiro."

Yaga examined Shiro for a moment before replying, "My name is Masamichi Yaga. I'm the teacher of this idiot and these two." He pointed towards Gojo, before pointing towards Shoko and Geto.

"I'm not an idiot..." Gojo grumbled.

Shiro chuckled at the interaction.

Shoko stayed rather quiet the whole time, but she had wanted to ask something.

"Shiro, if you can use the reverse cursed technique why don't you use that to get hair." Shoko was rather puzzled. Shiro had twitched at the mention of 'baldy' making it seem like he didn't like it.

"You can use the reverse cursed technique!?" Yaga didn't think there would be anymore surprises, but this was huge.

"No, I cannot. That was a result of my natural healing." Shiro said.

"WHAT?" Everyone was confused. To have such regeneration without the aid of a technique...

"Shoko, what did you mean by gaining my hair!" Shiro was excited to claim his hair back.

"Let me show you!!" Shoko moved her hand towards his head, and an aura soon enveloped her hand.

After a few minutes of silence, Shiro had hair...

Shiro held Shoko's shoulder as he spoke, "Shoko... I owe you." Shiro turned serious as he said this.

Shoko smiled in response. Seeing how serious Shiro's expression was she knew she couldn't refuse.

Shiro now had long black hair that reached his middle back. It was similar to his hair in the Baki world.

While Shiro looked rather charming without hair already, this new illustrious look was a definite plus.

Gojo, Geto and Yaga stared at the spectacle. Gojo felt rather sad that he couldn't annoy Shiro anymore. But he didn't know that Shiro would still execute his revenge...

"So am I a jujutsu sorcerer now?" Shiro asked as he turned to Yaga.

"Yes. And I have your first assignment. You already seem familiar with cursed energy, but there are other things you can learn later in the academy." Masamichi Yaga replied. Before Shiro could become a sorcerer he had an important assignment.
