Satoru Yagami sat quietly among his classmates at the end of the test, the buzz of the playground still humming with energy. Sweat clung to the foreheads of the exhausted students as the final results were announced. Yet Satoru's focus wasn't on the leaderboard or the teachers' praise.
It was on the transparent panel floating silently in his vision—a panel only he could see.
His system had awakened.
But even though excitement boiled in his chest, Satoru knew better than to act out. He was still just a six-year-old student at the Ninja Academy, and any rash behavior would easily draw unwanted attention.
Especially in a world where monsters walked in the skin of men.
He suppressed the grin trying to creep up on his face and kept his expression neutral. He had received the [Copy] ability—his golden finger, the cheat that would change everything. According to the system's information, [Copy] could duplicate anything from bloodlines and chakra natures to kekkei genkai, dojutsu, and even rarer attributes like kekkei mōra.
But it came with a restriction.
He could only use the [Copy] ability once a year. Fortunately, unused chances would accumulate, allowing multiple copies in future years if left unused.
That limitation would cripple most people.
But not Satoru.
Not in a world full of powerful bloodlines.
Even just within Konoha, there were the Uchiha with their Sharingan, the Hyuga with their Byakugan, and other smaller clans with valuable abilities.
The system also outlined the proximity-based activation requirements:
Touch: Instant copy.
Within 10 meters: 1 minute.
50 meters: 5 minutes.
100 meters: 10 minutes.
Which meant it was safest and fastest to copy by touch—and luck was on his side today.
Without drawing attention, Satoru casually made his way toward Naruto Uzumaki. The boy was grumbling to himself about training harder next time, completely unaware of the approaching Satoru.
As they passed, Satoru brushed against Naruto's left arm.
[Copy Available]
A soft glow lit up the panel only Satoru could see. His mind raced.
The system didn't display information about the target's abilities. He had to know what he wanted to copy beforehand. That was another critical restriction.
Luckily, Satoru had spent years in this world. He already knew the truth behind Naruto Uzumaki—he was the reincarnation of Asura Ōtsutsuki, the younger son of the Sage of Six Paths.
"Copy Yang Release from Ashura Chakra."
As the command silently echoed in his mind, the system responded.
[Yang Release from Ashura Chakra copied successfully. Proceed with fusion?]
Satoru didn't hesitate to withdraw his hand and walk away, blending back in with the other students. He kept his calm. Now was not the time for fusion—he had no idea what kind of side effects might result if he fused something as important as Yang Release in public.
He held his breath for a moment, calming his racing heart.
After the final rounds of physical training, the test finally concluded. Students packed up, chatted among themselves, and left one by one.
Satoru waved goodbye to a few enthusiastic classmates and returned home. Despite being just a six-year-old, his calm demeanor and precise taijutsu performance had already earned him some fans among his peers.
But right now, he had only one thing on his mind.
Unlocking his true power.
---
Once safely home, he walked into his bedroom, locked the door, and pulled the curtains shut.
"Fusion."
A golden light erupted from his body.
It was dazzling—briefly illuminating the room with the kind of flash you'd expect from a game character leveling up. His body glowed from within, the energy surging around him...
...and then it stopped.
Everything fell silent.
"Huh. For all that drama, I'd only give that special effect like... three cents," Satoru muttered dryly.
But he didn't waste time. He sat cross-legged on the floor, closed his eyes, and began drawing out chakra. He needed to feel if there was any internal change.
His body was that of a civilian child. No bloodline, no inherited talent.
But his soul—his soul was something else.
As a reincarnated adult, Satoru had spiritual energy far beyond others his age. Chakra was a combination of spiritual and physical energy. In his previous training, he always found that while his spiritual energy was exceptional, his physical energy was merely average—resulting in only a modest chakra pool.
But now...
As he focused on extracting chakra, something changed.
His spiritual and physical energies fused more harmoniously than ever before. His chakra flowed like a surging river, growing with a visible intensity.
If a Hyuga were to use the Byakugan to observe him now, they would see his chakra not only increasing in volume but glowing with a deeper, more vibrant blue.
It was multiplying.
And Satoru could feel every bit of it.
He opened his eyes—eyes filled with emotion and disbelief—and whispered, "So this is what it feels like to be a cheater..."
He couldn't help but smile.
The world of shinobi was cruel. Clan children walked into life already blessed with powers civilians could never hope to match.
But now, Satoru had Yang Release—the fundamental chakra nature that gave rise to the legendary Sage Body. He wasn't at that level yet, but the potential had been planted.
The path had opened.
Laughing softly, he stood up and looked at his reflection. "Haha… Suddenly, life feels meaningful. This world… it's beautiful again."
And he had been careful, too.
There was a reason he only copied Yang Release from Naruto and not Ashura's full chakra.
First, copying Ashura's chakra directly might bring unwanted consequences. Hagoromo Ōtsutsuki, the Sage of Six Paths, was known to appear in the spiritual world of those carrying his sons' chakras.
Satoru had no interest in being scouted or interrogated by that ghostly old man.
Second, even Ashura himself awakened the Sage Body due to the presence of Yang Release. It was the more efficient and subtle path to follow. He could grow naturally from here—without drawing divine attention.
Snapping back to reality, Satoru suddenly remembered something.
His beginner reward!
He had been so excited by the [Copy] ability that he'd nearly forgotten about the system's initial gift.
"System. Claim Beginner Reward."
The panel shimmered once again.
---
Opening Exclusive Beginning Reward…]
Rikugan (Six Eyes) with Limitless Technique
Saiyan Body (Zenkai Boost & Potential only)
Nameless Technique
---
Satoru's breath hitched.
Rikugan... the Six Eyes?!
He almost fell backward.
In the world of Jujutsu Kaisen, Rikugan was an absurdly rare dojutsu passed down in the Gojo Clan. It granted superhuman perception, the ability to see cursed energy in extreme detail, and perfect control over energy techniques—especially the Limitless Technique, which could manipulate space itself.
And now he had it?
He clenched his fists, his eyes wide.
Limitless... Infinity... Cursed Technique Reversal... even Hollow Purple in the future? The possibilities made his blood rush.
Next came the Saiyan Body. Though limited to only Zenkai Boosts and potential—it was still one of the most terrifying evolutionary traits in fiction. Each time he was pushed to his limits, his body would rebound stronger.
It was a survivor's gift.
