Reincarnated in Jujutsu Kaisen as Hashirama Senju

His hand throbbed with pain, feeling something calling him, demanding him, as if it wanted him to witness something. Then he felt it, a voice. The first word that came to his mind upon hearing the murmurs was "energetic." It was like that boy was an oxygen tank that would never run out.

Words like "Help, Fire, Domain Expansion, Reverse Technique, Cursed Energy, or Twin Dragons" could be heard and the rest was not understandable.

What was left of the voice was intelligible, and downright annoying.

It was then that he regained consciousness of where he was. He was in a dark space where he couldn't see anything. Upon inspecting his body, he noticed that nothing was out of the ordinary, except that his body was floating in a seemingly endless void.

An inexplicable heat surged into his being, increasing his temperature. Suddenly, a deep, almost ancient voice spoke to him.

"My name is Kagutsuchi and you, human, have received my will. The Senjuprakash truly left a user worthy of my blessing," The ancient voice said before continuing.

(Author's Note: The Indian surname derived from "Senju" that implies a connection with nature could be "Senjuprakash." The suffix "Prakash" means "light" in Sanskrit, symbolizing enlightenment and deep connection with natural elements. Thus, "Senjuprakash" could suggest someone who finds their spiritual guidance and connection in nature. Author's note ended.)

"I will show you your future. Those who inherit the blessing of Kagutsuchi have the right to see the future that awaits them, the place and time of their soul's future but never the context of the situation in which their soul finds itself. All those connected with Kagutsuchi are people whose fire in their souls burns brighter than the fire of a thousand volcanoes Itama Senju, you have received the blessing of Kagutsuchi, and this is the future that your soul must witness.."

His mind was teleported to a place.

His vision was dark, he couldn't see anything, he didn't know what was happening, he just felt that inexplicable heat, when he noticed it.

"DOMAIN EXPANSION: KINGDOM OF THE BURNING SOUL!" The boy's squeaky voice was there, but now it seemed more mature and darker as if that youthful, lively glow in his voice had faded. However, it was evident that it was the same voice as before.

Consequently, another voice followed the boy's, which was deeper and gave off excessive anger and hatred.

"DOMAIN EXPANSION: MALEVOLENT SANCTUARY!"

His eyes opened and before him were two spaces created of opposite colors with opposite people. Both spaces seemed to constantly collide to test which would consume the other first.

In the middle were two men, each with a different arm raised and their fingers crossed in a mudra as both spaces continued colliding.

"BRAT! HOW LONG WILL YOU KEEP GETTING IN MY WAY?" The voice of whoever said this belonged to a being with four arms, two of them destroyed and almost completely burned, with what seemed to be a mouth on its stomach that was destroyed and torn. The black marks around this area indicated that they had suffered the same fate as his arms. His chest was wounded in a way almost impossible to resist in human terms, also charred and open.

His face was shattered and one of his main arms seemed to slowly regenerate. His face was full of blood and he also seemed to be regenerating. He had two eyes on his right side that were directed at the boy in front of him.

The rest of the left side of his face was not visible due to blood and cuts. The man's mouth was constantly spitting blood, but his bloody smile indicated the opposite of what his physical state reflected.

Behind this man, an amorphous mass of what he usually saw on the streets of Tokyo, but in greater magnitude, manifested itself. Its part of the space that tried to devour the boy's was blood red.

The young boy, on the other hand, was covered in white flames. The right side of his face was shattered, his hair had turned the color of the flames that covered his entire being. His only visible eye glowed bright red. His clothes gave off flames from his shoulders, threatening to devour everything in his path. His clothes had turned completely white and his right fist, equipped with a kind of metal arm, was also white.

Just above the boy's head, the symbol of the Senju clan lay in the air, burning and shining brightly.

Behind him, a kind of torii gate rose, and with it, a shrine that had a throne with ancient decorations at the entrance.

Hearing his words, the boy gritted his teeth more and, with a determination clearer than ever, he spoke.

"I'm going to kill you, Sukuna."

The one identified as Sukuna only laughed loudly, while his anger grew more and his expression showed it by smiling with contained annoyance.

"YOU'VE ALREADY FELT ME, YOU DAMN BRAT! I'M GOING TO FINISH YOU, AND DON'T THINK THAT BECAUSE YOU GOT THAT POWER YOU'RE GOING TO DEFEAT ME. YOU'RE MORE THAN WRONG. YOU'VE ALWAYS BEEN THE SHADOW OF EVERYONE, YOU'RE NOTHING BUT TRASH AND TRASH SHOULD BE ELIMINATED. YOU ARE NOTHING BUT A SIMPLE PIECE OF SHIT, JUST LIKE YOUR FATHER!"

The boy's eye widened in surprise, but quickly evolved into anger.

Itama only saw everything, overwhelmed by the power of both individuals colliding with each other, while they looked at each other with hatred and wanted to kill the other. Just as he tried to move, a snap brought him back to reality, to the dark space from which he had been abducted moments before.

"What has happened?" Itama murmured with nerves and doubts. He had never experienced anything like this before. Everything had become strange since that thing suddenly appeared in his home.

His reverie disappeared just as the same deep voice returned from the shadows and began speaking to him again.

"I have shown the future to your soul. What you should know is that you will not remember any of this, only your soul will be able to do so. We will meet again once you are close to dying, boy. Become strong."

With that, his eyes closed as he began to feel an immense desire to sleep, a desire that did not exist there before.

**Jujutsu High, Tokyo, Japan, 4:05 PM.**

In a room of the multiple facilities of Jujutsu High, a girl with blonde hair and a slender body was lying on a chair while she looked worriedly at her brother, who was lying on the bed, sweating a little.

The girl, quite worried, passed a cold towel over her forehead to remove the sweat from her.

Somewhat frustrated, the girl sighed in annoyance as she muttered to herself.

"How long do you plan to sleep, Itama? I'm tired of wiping off your sweat."

Although the girl seemed upset, she was only worried about her little brother.

When nothing seemed like it was going to change, the boy stood up exalted with sweat falling from his face. This made the girl quickly move towards him and hug him tightly.

"You're finally awake," the girl said in a whisper as she stroked the boy's hair.

Faced with such a reaction, the boy remained without returning the hug and, only gently, after a long moment, he hugged his sister.

Burying his face in her shoulder, the boy murmured in a muffled tone but with notable sadness.

"Father is dead, isn't he?"

With that question, an answer never came from her. Only her silence hinted that her suspicions were real and that her father, Butsuma Senju, was dead.

"How are Hashirama and Tobirama? Are you okay?" Itama asked again.

"Yes, they're fine. Hashi is still unconscious, but it seems like we're in a much bigger mess, something much bigger than that thing that attacked us at home," Tsunade commented worriedly.

"That's good, but what do you mean we're in trouble?" Itama asked worried.

Before Tsunade could continue answering her questions, the door to the room opened and Gojo calmly entered.

"Yo, what's up Tsu-chan? I see your little brother is up," Gojo said with an arrogant, mocking smile.

At her mockery, Tsunade only ended up ignoring the man who spoke.

At her reaction, Itama asked confused.

"Tsunade, every time we call you a nickname, you hit us. The only one, according to you, who can call you that is Hashirama. Following your logic, shouldn't you be turning this guy to a pulp?" Itama said, confused at the situation that his eyes were witnessing.

A mark of annoyance appeared on Tsunade's forehead as the man continued to smirk.

"The thing is, I can't hit this damn bandaged guy. He has a pretty annoying thing that won't let me hit him," he commented as another mark of annoyance appeared on his forehead.

"It's called Infinity, Tsu-chan. It's a hereditary technique and it's Jujutsu," Satoru said with that smile still on his face before continuing, "But don't worry, it's not like your tiny brain will let you process everything. Thank goodness I, the GREAT GOJO SATORU, WILL BE YOUR TEACHER THIS SEMESTER!" he exclaimed with a triumphant smile and a facade that screamed 'EVERYTHING IS GOING TO BE WELL'.

"The day you remove infinity I swear I will beat you up, Gojo Satoru, remember that," Tsunade commented as he continued snapping his fingers.

Itama only had a drop of sweat fall from his forehead as he watched this interaction between them.

"But now there are more things to do. Itama, Tsu-chan, follow me. Let's go to Hashirama's room," Gojo commented as he left the room.

Getting up, Tsunade, dressed casually in a loose-fitting long-sleeved shirt, which somewhat hid her already developed attributes, and loose-fitting pants, both black, followed Gojo. Itama dressed the same way, but with flip flops to feel more comfortable.

Following Gojo, the Senju brothers, silent and tense, only wanted to reach their brothers to know the status of both of them.

After walking for a while, the three of them were in front of the room, and before entering, Gojo, who had been quiet and relaxed this entire journey, spoke with a smile.

"It's very likely... nah, it's 100% certain that that boy will attack me once he wakes up because of a tiny altercation we had before we met. I'm telling you this because I plan to play with him to show you what Jujutsu is, but relax, no." I will hurt him a lot and it won't hurt... I think," he said, causing an alarmed reaction in the brothers, who entered the room right behind the relaxed man.

Entering the room, they found a small white room, big enough to house them all. At the end of the room, Tobirama sat with his eyes closed and arms crossed, apparently sleeping. In his lap rested a completely black katana.

A few meters away from him, Hashirama was apparently unconscious, with bandages on his face, but smiling placidly as he rested on a bed.

The room was decorated with several paintings, an electric light bulb, and a nightstand. Right in front of the bed, a few meters away, attached to the wall, was a water filter.

As the three entered the room, Tobirama opened his eyes at that moment.

Tobirama's gaze quickly recognized Itama, then his sister, and finally the bandaged idiot.

"Well, well, someone seems to be in a very bad mood," Satoru Gojo said with a mocking smile.

"Being trapped here against my will doesn't make it any better," the grumpy Tobirama replied coldly.

"Oh come on, it can't be that bad, right?" Satoru said as his smile grew wider. "Anyway, I think your brother will wake up shortly and I'll take the opportunity to give you, my dear students, a taste of what Jujutsu is."

Tobirama's gaze lifted slightly. Now that he remembered it, that beast that attacked them said the same thing. Coming back to reality due to Gojo's annoying voice, he realized that his brothers had walked next to him.

"What's going on?" Tobirama asked, bewildered.

"That idiot over there said to come to you, Tobirama, and prepare for the trip," Tsunade said, annoyed and also confused.

"Journey?" Tobirama said, more questions crowding his head.

His gaze traveled to Satoru Gojo, who with a malicious smile approached Hashirama's bed and forcefully punched his stomach as he laughed and shouted loudly, "GOOD MORNING, SLEEPING BEAUTY!" causing everyone's eyes to widen at such an action.

Hashirama, dazed and in pain, shook his head to eliminate the discomfort and noticed a figure whose white hair defied gravity, similar to Hatake Kakashi, with bandages covering his eyes and a mocking smile.

After staring at each other, Hashirama recognized Gojo and immediately lunged at him hard, destroying the bed beneath him as if he had never been seriously injured.

With a smile, Gojo watched as Hashirama's punch never hit him and noticed how Hashirama's brothers' expressions paled.

When Tsunade tried to speak to stop Hashirama, Gojo cheerfully interrupted her, "STOP RIGHT NOW!"

Seeing that Tsunade obeyed his order for the first time, Hashirama fell to the ground again and forcefully launched a kick towards his belly, which Gojo stopped using his Infinity. Tobirama watched everything attentively and his eyes widened in surprise, although he tried to hide it.

'When he fought my sister, how did he manage to touch her? He's supposed to be untouchable, right? Oh, it's like that, isn't it?' Tobirama's smile became evident as he saw how, after the kick, Gojo stopped it. He held Hashirama's foot tightly as he smiled.

'It's not that you're untouchable. In a way, you are, but to touch others you need to deactivate your Infinity, right?' Tobirama thought as he saw his theory come true.

Just when he was planning to communicate his message, some black writings appeared in the shape of a circle below them.

Satoru just smiled and lightly pushed Hashirama away from him.

Crossing the fingers of both hands, he teleported them directly into the forest, leaving a crack in the ground in the aftermath of the teleportation.

"This is going to be fun," Gojo said with a smile, teleporting himself next to them.

Reappearing in front of the confused youths, Satoru smiled in amusement. "Well, well, who wants to be first?" he commented with a smile, knowing it would provoke a reaction from Hashirama.

And as he expected, Hashirama headed towards him at high speed.

"Well, those who don't fight should pay attention. Lesson number 1 of the day," he said as he dodged each of Hashirama's assaults.

"What is Jujutsu?" Gojo said, and forcefully, taking advantage of the fact that Hashirama had missed a palm strike, he grabbed him by the collar of his hospital shirt and sent him rolling on the floor with a smile.

With an annoyed smile, Hashirama took advantage of the distance and pointed one of his arms at Gojo, making him smile in amusement.

The roots emerged again, attempting to trap Gojo failing miserably.

"Hehe, time to show off a little." He said and with this Gojo disappeared from the area again making Hashirama alert.

His senses activated when he noticed Gojo at the top of one of the trees with a smile.

"It seems like you have an Innate Technique, I like it, I wonder what else it can do." He said with an amused smile making Hashirama's nerves stand on edge due to the annoyance this guy caused him.
