Who

At this juncture, Hiroshi Senju was methodically dismantling and redefining the structures and norms within the Sorcerer world, with the unyielding support of Satoru Gojo and Suguru Geto. Managing the smaller aspects proved straightforward; the true challenge lay in gaining the cooperation of the conservative faction. The Jujutsu higher-ups were steadfast in their adherence to tradition, often to the extent of hindering the initiatives of the Senju and Gojo clans.

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

When asked "Who is Hiroshi Senju to you?" the responses varied significantly among his peers:

Satoru Gojo, always candid, responded first. "Hiroshi? Childhood friend and my best friend," he stated simply.

Suguru Geto offered a more reflective answer. "Who is Hiroshi to me? A guide, a mentor, best friend, a moral compass, or something along those lines," he mused.

Shoko Ieiri's eyes twinkled with affection as she considered her reply. "Hiroshi, my lover, husband? Is it too early to say?" she chuckled, her smile suggesting she found the title quite fitting.

"Huh? When did you and him start dating?" Satoru appeared genuinely surprised.

"Satoru, you have always been so slow," Suguru said, facepalming at his friend's obliviousness.

"Been two years now, hehe. You're so slow, Satoru. Don't keep Utahime waiting, you know," Shoko teased, smirking knowingly.

"Shoko, what do you mean by Utahime?" Satoru asked, clearly baffled.

"Hehe," was all Shoko offered, her chuckle echoing her amusement.

The question was then posed to Nanami, Haibara, and even Yuki—and somehow the interviewer had managed to consult Master Tengen as well.

"Well, a caring senior, a goofball, and the wealthiest man in the world," Nanami described, capturing multiple facets of Hiroshi's personality.

"My saviour... I know deep down that he sent those two Senju sorcerers," Haibara Yu acknowledged, gratitude evident in his tone.

"Senju Hiroshi? A fate changer," Master Tengen declared, her words carrying the weight of ancient wisdom.

"It is without a doubt, he is," Yuki Tsukumo concurred, affirming Hiroshi's revered title, "The God of Sorcerers."

"Stronger than you?" The question hung in the air, prompting Yuki to respond with a knowing smile, "Who knows?"

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

"So, is Satoru on Megumi duty?" Hiroshi asked Suguru as they walked towards the training area. A strange sight greeted them: Megumi's Max Elephant was floating just above Satoru Gojo, while Megumi himself lay helpless under Satoru's foot, looking utterly defeated.

Seeing this, Suguru was speechless, while Hiroshi burst into laughter.

"Satoru! When I said 'train Megumi,' I did not mean 'step on the child'!" Suguru angrily scolded.

"What? He was the one who asked for it. Megumi explicitly said, 'Don't worry about me, train me the best you could,'" Satoru explained defensively.

"Hahahahahahaha!" Hiroshi laughed uproariously as Suguru continued to reprimand Satoru Gojo.

Under the trio's tutelage, Megumi was improving rapidly.

June 2012,

Hiroshi stood in front of Megumi, with Satoru and Suguru watching.

"Since Satoru is teaching you how to actually throw hands, and Suguru is guiding you on how to fight using Shikigami, I, on the other hand, will teach you Domain Expansions, Simple Domains, and much more," Hiroshi said seriously.

"But first," Hiroshi said, "put 'em up!" Suddenly, he threw a punch at Megumi's face.

"What?" Megumi was confused, but his confusion didn't last long as he was hit directly in the face by Hiroshi.

"Hahahaha," Satoru laughed, while Suguru facepalmed. "I knew Hiroshi was going to do that eventually. It's already a miracle Hiroshi didn't hit him when he was a child."

"Why did you do that!?" Megumi said angrily.

"Ah ah ah! Did you learn nothing from Satoru? Always be ready for a fight," Hiroshi smirked. "Now show me what you've got."

Megumi squared up, swinging at the air as Hiroshi easily dodged his punches.

"Remember, Megumi, inside a Domain Expansion, if both sorcerers are equal, it all comes down to the first sorcerer to receive more damage and be forced to heal himself. And that means sorcerers must have hands; otherwise, you get cooked," Hiroshi advised seriously as he caught Megumi's swing and slammed him to the ground.

"Now, a Simple Domain." Hiroshi launched his own Simple Domain. "The New Shadow Style is the simplest and most effective Simple Domain today. You can program it for whatever purpose you desire. The best Simple Domain user today is Kusakabe Atsuya; he may not look like it, but he is strong." As Hiroshi kicked Megumi up and simultaneously applied Reverse Cursed Technique to heal him.

"Feel the pain; it means you are alive. You are the child of the greatest assassin of this generation, and you possess the Ten Shadows, arguably the deepest bag of techniques in the Sorcerer World, just below mine, of course. I will not allow your potential to go unrealized, whether you like it or not," Hiroshi said firmly.

"Now, here's a question: Do you want to be strong?" Hiroshi asked.

"Yes," Megumi replied, but Hiroshi hit him. "Louder!" he demanded.

"YES, I WANT TO BE STRONG LIKE YOU!" Megumi shouted.

"Good, now focus. This is the Falling Blossom Emotion, an Anti-Domain Technique. The difference between Simple Domain and Falling Blossom Emotion is that one is defensive and the other is offensive. Falling Blossom Emotion enables you to parry sure-hit effects and move forward," Hiroshi explained as he demonstrated the technique.

Megumi studied Hiroshi's stance and began to emulate it. Despite his techniques being unstable, he followed Hiroshi's teachings diligently.

"Now, Domain Amplification can be learned later on, once you have an Incomplete Domain," Hiroshi added.

As the spartan-like training continued, Hiroshi forced Megumi to adjust his mentality.

29 Days Later...

Hiroshi forced the "Go hard or go home" mentality on Megumi. "If you're getting your ass kicked, that means you're doing something wrong," Hiroshi said as he kicked Megumi. Pissed Megumi distanced himself from Hiroshi as he chanted, "With this tre-" He was cut off as Hiroshi interrupted him. "Get outta here, you trying to suicide bomb yourself? Do that again, and I'll kick your ass even harder," Hiroshi chided. "Now, focus!"

Megumi looked Hiroshi in the eye and said, "Domain Expansion: Chimera Shadow Garden!"

Seeing Megumi unleash his Domain, Hiroshi nodded. "Good...you only need to get your ass kicked to finally get it," Hiroshi said as he patted Megumi on the back.

"Did you...get your ass beaten too while training?" Megumi asked Hiroshi.

"No, I was born with talent. I just needed to work hard. But you...you need your ass beaten to get it, for some reason," Hiroshi replied.

"Summoning Mahoraga is never the answer, Megumi. Dig deeper into your bag of tricks. Do something like combining five or more Shikigami or something. Tell you what, if you can actually force me to use at least one Cursed Technique, I'll help you tame Mahoraga," Hiroshi smirked.

"How do you know its name?" Megumi asked, shocked, thinking he was the only one who knew about Mahoraga.

"Hehe, I took it from the Zenin Clan's records," Hiroshi chuckled.

July 2012,

Every month, the trio took turns training Megumi. Now it was Suguru's turn.

Different from Hiroshi's spartan training and Satoru's impossible-to-win scenarios, Suguru's method of training was patient.

"Megumi, summon your Shikigami," Suguru instructed as Legions of cursed spirits manifested around him like an army.

"Divine Dog: Totality!" Megumi summoned a large wolf with white and black patches. Under Suguru Geto's mentorship, Megumi had learned early on the depth of his bag of tricks.

"Focus on controlling your cursed energy output, just enough to summon and still have enough in reserve," Suguru advised.

"Tiger: Totality Minotaur!" From the shadows emerged a creature with the face of a bull and the body of a tiger funeral, a bipedal creature with the stripes of a tiger, the claws of a tiger, the hooves of an ox, and its powerful muscles.

Megumi's Shikigami attacked, but similar-sized creatures from Suguru's Legions intercepted both Totalities. However, the Ten Shadows proved strong, tearing through Suguru's cursed spirits.

However, Megumi hadn't taken into account that Suguru had disappeared. Before he realized it, Suguru Geto was behind him. With one swift chop, Megumi was unconscious, and the fight was over.

June 2013

Nanami had begun his foray into the mundane world as a salaryman, with Yu Haibara in tow.

"What made you go to work in the Mundane World?" Hiroshi inquired, curiosity coloring his tone.

"I got tired of being a Sorcerer," Nanami replied succinctly, his gaze drifting slightly as if he were contemplating the weight of his past life. Beside him, Haibara shrugged, adding, "I'm just tagging along with Nanami."

Meanwhile, Shoko had reached a significant milestone, graduating from medical school that same month. Her achievement marked a new chapter, not just in her professional life but in her personal one as well, particularly with Hiroshi.

"Darling," Shoko began, her voice carrying a soft, melodic undertone.

"Hmm?" Hiroshi responded, turning his attention fully towards her.

"Did you know there are 206 bones in the human body?" she queried, her eyes locking onto his.

Hiroshi's response came with a smirk, tinged with the typical flair of their intimate banter, "207 when I'm with you."

"Stop," she chided, a light blush coloring her cheeks. Despite anticipating Hiroshi's antics, his words still stirred a flutter in her heart. "It's still too early. I am trying to share information about the human body," she asserted, her tone firm yet gentle.

Seeing Shoko's cheeks bloom with color, Hiroshi chuckled softly, his amusement clear. This only served to elicit a pout from Shoko, who expressed her mock annoyance with a huffy "Hmph!"

This display of affectionate exasperation drew Hiroshi closer, compelling him to wrap his arms around her in a comforting embrace. "Now you are being cute. I'm listening, continue," he encouraged warmly, his voice a soft murmur against her ear.

Shoko quit Smoking.

In March 2014, Satoru and Suguru were on a special-grade mission due to the disappearances of sorcerers in the Sea of Trees.

Upon entering, Satoru and Suguru immediately sensed the cursed energy emanating from the resident cursed spirit.

"Ahh...it's weak; you can handle it, Suguru," Satoru said, nonchalantly munching on a Kikufuku.

"But that one in the middle is special grade," Suguru Geto noted as legions of cursed spirits marched out, filling the entire Sea of Trees. With a swipe of his hand, he absorbed the cursed spirits weaker than him.

As he did this, the special-grade cursed spirit, taking the form of a walking tree with blood stains, lunged at Suguru Geto. But before it could reach him, a massive skeletal hand scooped it up, allowing Suguru to absorb it effortlessly.

With the forest exorcised, Suguru declared, "Alright, we're done here."

"Ah, that was easy," Satoru commented. "Boba?" Suguru suggested.

"Sure," Satoru replied.

In April 2014, Hiroshi was training Megumi on how to exorcise cursed spirits in a specific area.

"Divine Dogs," Megumi commanded, using the Ten Shadows. Under the trio's tutelage, the Divine Dogs had significantly improved, taking on stronger forms due to Megumi's cursed energy reinforcement.

Observing Megumi, Hiroshi felt his cursed energy was still insufficient.

"Megumi, come here for a bit," Hiroshi gestured. He touched a tree, causing it to sprout a peculiar fruit, which he then handed to Megumi.

"Eat it," Hiroshi instructed.

"What? This looks disgusting," Megumi protested, but he trusted Hiroshi and took a bite.

As he did, he felt his cursed energy reserves skyrocket. If his cursed energy had been a small pond, it now felt like a sea.

"Anymore fruits, Sensei?" he eagerly asked.

"Unfortunately, you can only eat one fruit, as eating more won't affect you any longer," Hiroshi explained.

"But what is this fruit?" Megumi inquired.

"It's the Cursed Fruit. It comes from the cursed spirits whose energy was absorbed and then turned into fruit. I can keep eating them because I'm the owner, but for outsiders, you can only eat one," Hiroshi elaborated.

"No wonder your cursed energy is always growing," Megumi remarked as he refocused on his exorcism.

The Divine Dogs alerted Megumi to a cursed spirit that was keeping children hostage but also providing them with food.

"Great Serpent!" Megumi summoned, and the Orochi attacked from beneath the shadow of the cursed spirit, swiftly gobbling it up and effectively exorcising it.

"Sensei, what do we do with them?" Megumi asked, gesturing toward the freed children.

"Well, they are orphans, or probably lost children, so return them to their parents, or if they have potential to be sorcerers, I'll adopt them into the Senju Clan," Hiroshi explained. As he did so, Senju personnel began to appear.

"Come, Megumi, let's continue our training," Hiroshi said, leading the way as Megumi followed.

A blond child watched Megumi intently.

September 2014,

At Kyoto Jujutsu High, the school had undergone significant transformation under Hiroshi's leadership. It now appeared even grander, with expansive gardens, well-equipped training grounds, and a dedicated Cursed Spirit Arena for practical experience. The cafeteria, resembling more of a cozy cafe, became a favorite spot for sorcerers to gather when not on missions.

Hiroshi, enjoying a burger in the cafeteria's homely ambiance, was approached by Kusakabe, accompanied by a blue-haired girl.

"Senju-san," Kusakabe began, "Hmm? No need for honorifics, Kusakabe. We are all peers here, regardless of strength," Hiroshi replied.

"Right... I'd like to enroll my apprentice at Kyoto," Kusakabe requested. "Isn't that Gakuganji's responsibility as the principal?" Hiroshi inquired.

"The principal is currently unavailable, so you're the second person I know who has authority over Jujutsu High," Kusakabe explained.

"Ah, I see. Just a moment," Hiroshi said, dialing his phone. "Yes, Patriarch?" he spoke into the phone.

"Get me someone from the office at Kyoto Jujutsu High. I need some enrollment documents," Hiroshi instructed. "Right away, Patriarch," the voice on the other end responded before ending the call.

"While we wait, why don't you have something to eat, Kusakabe, and..." Hiroshi turned to the girl beside him.

"Kasumi Miwa is my name, God of Sorcerers," she said, gazing at Hiroshi with admiration. She even asked for his photo, to which Hiroshi obliged.

A few minutes later, a Senju sorcerer arrived in the cafeteria carrying the necessary enrollment documents.

Kasumi Miwa has been enrolled.

"But I'd like to train her for a few years before she actually attends school, Senju-san," Kusakabe expressed.

"That's fine. As the strongest Simple Domain sorcerer, you can handle her training. I'll explain the situation to Gakuganji," Hiroshi agreed.

"The strongest Simple Domain sorcerer... Surely you jest," Kusakabe responded awkwardly, feeling a mix of surprise and pride at being acknowledged by the God of Sorcerers.

June 2015, Kyoto Jujutsu High 

Hiroshi's mentorship had finally gained three students: Noritoshi Kamo, Aoi Todo, and Momo Nishimiya.

Standing in the training ground, Hiroshi awaited their arrival.

Noritoshi Kamo greeted him first, showing his respect. "Sensei, it is an honor!" he exclaimed. "Hmm? It's the Blood Manipulation Kid. Come, show me what you know while we wait for the others," Hiroshi responded.

A few minutes later, a muscular man and a blond girl floating on a broom arrived.

Noritoshi Kamo, though bruised, had learned to efficiently control his blood manipulation during their time together.

"Sensei! I am Aoi Todo," the muscular man introduced himself.

"Nishimiya Momo," the blond girl followed suit.

Hiroshi was aware of Aoi Todo's capabilities, although it was unfortunate that his hand and Cursed Technique were later destroyed by Mahito.

"Perhaps I can change that," Hiroshi thought as he approached Todo.

"Tell me, Todo, what kind of girls do you like?" he asked with a smirk.

"I like tall girls with big butts," Todo answered confidently, but he was swiftly hit by Hiroshi, sending him flying backwards. "Correct answer," Hiroshi chuckled.

Todo suddenly reappeared beside Hiroshi. "He's using Boogie Woogie already? Yuki must be a good mentor," Hiroshi thought. Before Todo could grab hold of him, Hiroshi swiftly brought him crashing to the ground.

"Alright, that's enough. Let me introduce myself," Hiroshi said, addressing the trio. "I am Senju Hiroshi. You may or may not know me, but by the end of your time here at Jujutsu High, you will know me as the mentor who favors Spartan training. It may not be pleasant, but you will certainly benefit from it."

The Plight of Hiroshi's Students Began.

November 2015,

Nanami and Haibara contacted Gojo Satoru and Suguru Geto to return to their lives as sorcerers.

November 11, 2016,

The trio, consisting of Senju Hiroshi, Gojo Satoru, and Suguru Geto, was sent to investigate a cursed spirit incident involving non-sorcerers being stuffed into lockers.

As they arrived, Hiroshi realized, "So JJK 0 Begins," he thought to himself.

"What an odd cursed spirit. Don't they just eat people? Why stuff them in a locker?" Satoru asked.

"Perhaps it's a unique cursed spirit," Suguru suggested.
