Transmigrated As Satoru's Father

Author's Notes:

Get ready, I porbably did a lot of crap in information regarding limitless and six eyes lmfao.

===================

"He can sense energy on his first try, huh? That's impressive."

In a vast, endless void where countless portals floated freely, each showing glimpses of different worlds, an elderly man sat upon a grand, imposing throne.

His features were sharp and distinct—deep-set eyes, high cheekbones, and an angular jawline, all giving him a regal, almost Germanic air. Once dark, his hair had long since turned silver with age, yet his presence exuded an undeniable strength, as though the years had only honed his power rather than diminished it.

He leaned forward slightly, his sharp eyes fixated on one of the portals directly before him. The scene it displayed was of Seijuro—David—carrying Satoru, a smile radiating warmth and joy.

The elder's gaze softened momentarily, but only for a fleeting second. His eyes then narrowed, scrutinizing every detail of David's movements, every subtle pulse of his energy.

"It's just a matter of time before he realizes it," the man muttered under his breath, his voice deep and laced with amusement and something darker. "But he hasn't noticed yet that it's not cursed energy. Even that kid has sensed the difference before him."

He leaned back into his throne, one hand stroking his chin thoughtfully. The energy David unknowingly unleashed was powerful but wasn't part of the jujutsu world's framework. It wasn't cursed energy. Not even close. And yet, David remained oblivious to the true nature of the power flowing through him.

The old man's lips curved into a small, knowing smile. "But the real question is... when will he realize it?"

The void around him seemed to pulse in response to his words, the portals shifting slightly as if the very fabric of the worlds themselves acknowledged his presence. He was not a mere observer.

No, his interest in David—or Seijuro—was not passive. He had plans.

As David grew more comfortable in this new world, and as he unraveled the mysteries of his powers, the elder knew that their paths would inevitably cross.

"It's only a matter of time," he repeated, his voice echoing through the void.

The old man's gaze remained locked on the portal, his smile deepening as he watched the events unfold. He was patient. After all, he had waited for this moment for a long time.

"Haa!" Seijuro stretched his arms upward, his muscles relaxing as he let out a satisfied sigh.

The room around him was spacious and elegant, a traditional master bedroom fitting for the head of the Gojo clan. The tatami mats beneath his feet were immaculately clean, their pale straw color adding to the room's serenity.

The sliding shoji doors were made of dark wood and intricately detailed rice paper, allowing the morning light to filter through with a soft, ambient glow. In one corner of the room, an antique lacquered dresser stood beside a low, polished table adorned with a few delicate porcelain cups. The room exuded a sense of order and dignity befitting someone of his stature.

The walls were decorated with hanging calligraphy scrolls and serene ink paintings of mountains and forests, adding to the peaceful, almost meditative atmosphere. Seijuro could tell that this space had been meticulously maintained—everything in its place, nothing out of order. It was the kind of environment the previous Seijuro would have demanded.

—Shhh...

The quiet sound of a sliding door broke the stillness, and Seijuro turned around to see Satoru standing at the entrance. His son's hair was still messy from sleep, with strands of white sticking out in various directions. He wore a dark blue kimono that hung loosely on his small frame.

"Father..." Satoru's voice was soft, almost hesitant.

"Satoru?" Seijuro replied, a bit surprised to see him this early.

Satoru shifted on his feet, avoiding eye contact momentarily before continuing. "...We have our daily training to do, Father, but... you're late."

There was a moment of hesitation when Satoru said the word late. He was perhaps even afraid of how his father might react. In the past, Seijuro had been punctual, strict, and sometimes unforgiving. Satoru had been conditioned to expect a long lecture if anything wasn't perfect, and his hesitation spoke to that lingering fear.

"Oh..." Seijuro mumbled, his mind racing.

'So, I have training with Satoru?' he thought, still piecing together the daily routine of the original Seijuro.

This was good in one sense—it gave him another chance to bond with Satoru. But it was also bad because he only theoretically understood the Gojo clan's techniques. The idea of practically training Satoru when he barely knew how to wield the powers was nerve-wracking.

But Satoru was waiting for him. And it wasn't just the training. His son expected him to show up, meaning Seijuro had to follow through and decide whether he was ready.

"Just... wait for me, Satoru. You can go to the kitchen and ask for food while you wait," Seijuro said, forcing a calm smile.

Satoru blinked, a bit surprised by the suggestion.

"...Yes, Father."

He hesitated for a moment longer before sliding the door closed and leaving.

As soon as Satoru was out of sight, Seijuro sighed, running a hand through his white hair.

'This is going to be tricky,' he thought, knowing he'd have to improvise regarding training.

He wasn't the original Seijuro, after all. He had memories of the Gojo techniques, but he hadn't put them into practice yet.

Meanwhile, as Satoru quietly made his way to the kitchen, he couldn't help but feel a strange mixture of emotions. He had been waiting in the training grounds for over an hour, and his father had not.

It was unusual—his father had always been punctual, almost obsessively. He initially thought something might have happened, but another part worried that his father had reverted to his old, distant self.

For a moment, Satoru hesitated, unsure if he should approach his father in the master bedroom. In the past, waking or interrupting his father could have led to sharp reprimands and cold lectures on discipline and punctuality.

But today... something was different.

His father wasn't the same man he had known in the past. The cold, distant presence that had defined Seijuro was gone. In its place was someone warmer who smiled, ruffled his hair, and suggested he wait for food in the kitchen—something that would never have happened before.

Satoru's mind swirled with confusion, but deep down, there was also a flicker of hope. Maybe this version of his father wasn't going to disappear. Maybe this version—the one that smiled and let Satoru lead—was here to stay.

For now, Satoru would wait, unsure of what would happen next.

✦✧✦✧✦✧✦✧✦✧✦✧✦✧✦✧✦✧✦✧

Seijuro followed Satoru through the compound, letting his son lead the way to the training grounds. As they walked, it became apparent that Seijuro didn't know where this place was, so he allowed Satoru to guide him.

Eventually, they arrived at an open area, a large training field. The ground beneath them was dry and cracked, with patches of dirt scattered where grass once grew. It looked like the ground had been torn apart countless times, the remnants of previous intense training sessions.

Seijuro looked around, taking in the sight. This area had seen its share of battles—whether against curses or during training. It was as though the earth bore the scars of the Gojo family's relentless pursuit of strength.

"So..." Seijuro clapped his hands together, breaking the silence. "Can you recall what you've learned so far, Satoru?"

This was a strategic move. Seijuro needed to know what the original Seijuro had taught Satoru; this was his way of gauging his progress without giving away his lack of knowledge.

Satoru, standing at attention, met his father's gaze. "Yes, Father," he began, his tone formal yet calm. "I've been practicing my control over Infinity. As you've taught me, it is the core of my Limitless technique, allowing me to manipulate the space between myself and anything else, creating an infinite barrier."

Seijuro listened intently, nodding as Satoru spoke. The boy's explanation was precise and clear. Despite his young age, Satoru spoke with a maturity that belied his seven years.

Satoru continued. "I'm still mastering Blue, the reversal technique that attracts objects or curses toward a single point. It's... tricky. I can generate it, but controlling the pull without destabilizing it is hard."

Seijuro's eyes widened in surprise, though he kept his composure. Blue was a powerful technique, one that required incredible precision and control. The fact that Satoru could even use it at his age was astounding. He's young, yet he's already grappling with concepts and techniques that take most sorcerers a lifetime to learn.

"And what about Red?" Seijuro asked, curious.

Satoru hesitated for a moment before responding. "Red... is difficult. It's the opposite of Blue, repelling objects or curses. I've tried to use it, but the repulsion force is harder to manage. It requires a lot more cursed energy control."

Seijuro couldn't help but feel a surge of pride. Even if Satoru was blessed with the Limitless technique and Six Eyes, his natural talent was extraordinary. At a young age, he had already begun to grasp the fundamentals of one of the most complex techniques in jujutsu sorcery.

"You're incredibly talented, Satoru," Seijuro said, his tone full of admiration. "To be at this level at your age... it's nothing short of amazing."

Satoru blinked, his eyes slightly widening in confusion. Praise was rare from his father—at least, the old version of him. He hesitated, unsure how to respond. "Thank you, Father."

"By the way," Seijuro added, curious now, "how old are you?"

Satoru's eyebrows furrowed slightly, unsure why his father would ask something so basic, but he answered nonetheless. "I'm seven, Father."

Seijuro nodded, but inwardly, he was stunned. He was seven years old. At that age, most children wouldn't fully grasp cursed energy.

Satoru wasn't just exceptional because of his bloodline—he was talented.

"I'm impressed," Seijuro said, smiling. "You've done so well to get this far."

Satoru shifted slightly, his posture stiff, still processing his father's praise.

"And how is your progress with Six Eyes?" Seijuro asked, eager to hear more about the legendary technique passed down through their family.

Satoru's expression grew more focused as if he were giving this question extra thought. "My Six Eyes allow me to see the flow of cursed energy with extreme precision. I can detect even the smallest fluctuations. But... it's overwhelming at times. Seeing everything with such clarity can be distracting. I'm still learning how to manage the information without losing focus."

Seijuro nodded thoughtfully. It made sense. The Six Eyes was an incredibly powerful tool, but managing its input would be challenging at such a young age. Even with all of Satoru's talent, mastering such a complex ability would take time.

"You're doing well, Satoru. Very well," Seijuro said, his tone warm and encouraging. "I know it must be overwhelming at times, but the fact that you've come this far... it's impressive."

Satoru looked up at his father, searching his face for any sign of disapproval or criticism, but he only found genuine pride. Satoru felt something new in his father's presence—comfort for the first time in a long while.

"Thank you, Father," he said quietly.

Seijuro, still processing everything Satoru had just explained about his progress with cursed techniques, felt another question come to mind. His thoughts drifted to something that had always intrigued him from the manga. He clapped his hands together again, this time with a more serious tone.

"What about close combat?" Seijuro asked, his curiosity piqued.

He knew from the manga that not even Sukuna—the King of Curses—could match Satoru in close-quarters combat. But this was early in Satoru's development, and Seijuro was curious to know how well-rounded his son's training had been.

Satoru's expression didn't shift much, though he seemed to consider the question momentarily. "I've been trained in close combat, Father," he replied steadily. "I'm confident in my physical abilities and learned how to integrate cursed energy into my strikes. But it's mostly focused on self-defense and using my cursed techniques to enhance my movements."

Seijuro couldn't help but smile. Even at his young age, Satoru was already becoming an incredible fighter. Still, the mention of his close combat skills made Seijuro think. His son might be exceptional in sorcery, but what about martial arts? There was a potential gap there that could be filled.

An idea sparked in Seijuro's mind. He knew how to take Satoru's physical abilities to the next level.

"Satoru," he said thoughtfully, "how would you like me to teach you some additional martial arts? Specifically, Aikido and Koppojutsu?"

Satoru's brows furrowed slightly, a flicker of intrigue passing through his eyes. "Aikido? Koppojutsu? What kind of martial arts are those?"

Seijuro crossed his arms, smiling as he explained. "Aikido is a martial art that focuses on using an opponent's force against them. Instead of directly opposing them, you redirect their energy to neutralize their attacks. It's about controlling movement, fluidity, and timing."

"And Koppojutsu," he continued, "is a much more aggressive art. It's focused on attacking the skeletal system—breaking bones and disabling an opponent. It's a lot more brutal but incredibly effective, especially when combined with physical strength and precision."

Satoru listened attentively, clearly intrigued. "But how would that be useful for fighting curses, Father?" he asked, tilting his head slightly.

Seijuro's smile deepened. "It's true that you'll mostly be fighting curses, but as a future sorcerer, you won't just be fighting them. There will be times when you'll have to face humans, too—especially sorcerers who oppose you."

Satoru's eyes widened slightly at the thought.

"Most curses can be fought with cursed energy, but humans—especially those with heavenly restrictions or immense physical strength—can pose just as much of a threat. You'll need to be able to handle opponents who can match your physical abilities. That's where martial arts like Aikido and Koppojutsu come in. You can apply these techniques even more effectively with your cursed energy, boosting your physical strength."

Satoru nodded slowly, processing the information. It made sense. Not all enemies would be curses, and understanding how to combat powerful human opponents would round out his abilities. The idea of being trained in something beyond cursed techniques intrigued him.

However...

"Why would I need to master hand-to-hand combat too? With infinity, nothing can touch me."

Seijuro smiled. "Some people possess cursed tools that negate cursed techniques."

"I see..."

Seijuro's eyes glinted with excitement. "Great! Let's start with a basic move from Aikido."

He took a few steps back, positioning himself as Satoru watched closely. "The key to Aikido is to use the opponent's momentum against them. Instead of resisting their attack, you flow with it and redirect their energy."

Seijuro then demonstrated a simple wrist lock, moving slowly to show how the technique worked. He extended his arm, imagining an attacker grabbing him. With a swift, fluid motion, he grabbed the imaginary wrist, twisted it gently, and brought it down in a circular motion, redirecting the imaginary force and locking it into a neutralized position.

"Try it on me," Seijuro said, stepping closer to Satoru. "Pretend I'm an opponent."

Satoru hesitated for a moment but quickly composed himself. He reached for Seijuro's wrist, mimicking the movement his father had just shown. He executed the wrist lock with a smooth twist, though he applied it cautiously, unsure how much force to use.

"Good!" Seijuro exclaimed, impressed with Satoru's quick grasp. "Now, do it again, but faster."

Satoru nodded, his confidence growing as he repeated the move. This time, his movements were sharper and more precise. Seijuro could already see the potential in his son's technique.

After a few more practice runs, Seijuro smiled and nodded in approval. "You've got the basics down. We'll work on applying cursed energy to boost your physical power when we practice this technique further."

Satoru seemed more invested now, his mind fully engaged in the idea of mastering not only his cursed techniques but also physical combat.
