"Ugh, I shouldn't have taken those pills from that guy," muttered a boy who looked about seven years old. His eyes were heavy with exhaustion, yet he seemed jittery, like caffeine was running through his veins. He had silver hair and striking blue eyes.
"Why do I feel so… light?" he asked, staring at his hands in shock. He turned around, examining himself like his body was new to him.
"No way, right?" he whispered, glancing up at the night sky. The stars reflected in his eyes as he grinned with excitement.
"This isn't my body—it's a kid's!" he exclaimed.
He suddenly burst into laughter. "Kekeke, HAHAHAHAHA!" In a flash, he jumped onto the railings, balancing with ease.
"Where are the women? Where are the lolis? Where's my succubus demon?" he cackled, sounding absolutely insane—because he was.
[Please Shut Up]
"Huh? Who said that?" The boy looked around but saw no one.
[I'm in your head, you horny idiot.]
"So you're giving me head?" the boy said with a smirk.
[No! I'm IN your head. Why am I stuck with such a pathetic excuse for a human being?]
"Well, at least I exist in the real world and not as a voice in someone's head," he retorted.
[...]
[Okay, fine. Do you even realize what's happening?]
"Yeah, I'm in an isekai, right? Everyone dreams of this! So, what world is it? Some secret fantasy land? High School DXD? Are you about to send me to steal Issei's dragon, or should I go put Rias in her place?" the boy asked, sounding thrilled.
[No, you're in Naruto.]
The moment the words registered, the boy froze.
"Out of all the worlds, it had to be Naruto," he groaned, grabbing his head. His excitement vanished instantly.
[It's not that bad.]
"Not that bad? I'm probably in Konoha, where Danzo kidnaps kids for talents, and Hiruzen spies on everyone 24/7. If I show even a bit of skill, Danzo will come for me. Hiding it won't be easy—these are real ninjas, not dumb characters in fanfiction! And if I'm in some other village, who knows what kind of madness goes on there?" the boy ranted.
[Well, at least you're not in One Piece as a sky slave or in Bleach, where Aizen would use you as his guinea pig.]
"True, but still..." he trailed off, realizing how hypocritical he sounded after complaining about his luck.
"Wait, are you some kind of system here to help me?" he asked.
[Sort of. I'm the Jujutsu Kaisen Template System. You'll get abilities from JJK characters. Isn't that cool?]
"Jujutsu Kaisen? Cursed Energy and Chakra are completely different! If I get a Heavenly Restriction, I'm doomed," the boy complained.
[Cursed Energy is basically Yin Chakra, and Reverse Cursed Energy is Yang Chakra. You're kind of like Kurama—a being of negative energy.]
"Alright, but shouldn't I have the memories of this body? How am I supposed to fit in without them?" he asked.
[You'll get them after you sleep and wake up.]
"Fine." The boy sighed, jumping off the railing. He walked into a large room that felt oddly familiar. Without overthinking, he lay down on the couch and fell asleep.

"So, my name is Cid Gojo," the boy muttered to himself. "Both parents were Jounin. That explains this fancy house. They died on ANBU missions, leaving this kid behind. Fueled by revenge, he trained relentlessly and became the top-ranked student at the academy—surpassing even Sasuke Uchiha."
Cid—or rather, the boy now known as Cid—had woken up just five minutes ago and received a brief summary of the kid's memories.
"Status," he muttered.
[Name: Cid Gojo
Bloodline: The Honored One
Cursed Techniques: Shrine
Template: Ryomen Sukuna (1 Finger)]
"Oh my," Cid said, smirking. "Things just got interesting."
Cid stood up. "Hmm, time to test this out," he muttered, stepping into the garden. It was only six in the morning, and the early sunlight stung his eyes a bit.
Closing his eyes, he instinctively formed a hand sign. "Dismantle," he said, and in an instant, a nearby tree was sliced cleanly into pieces.
As he opened his eyes, a malevolent grin spread across his face. "Kekeke, I like that."
"I should test my abilities further," Cid said. From the boy's memories, he recalled the hand sign for the Clone Jutsu—a technique usually reserved for academy graduates but one this boy had already mastered.
However, when Cid tried it, nothing happened. "W-what? From the memories, he executed it perfectly every time. What the hell?"
[Did you forget? As a being of negative energy, you use Yin Chakra. Only Yin Release or Yin-based Jutsu are available to you.]
"Right," Cid said, frowning. "Clone Jutsu relies on a balanced chakra system. Hmm..." He paused, deep in thought.
"Sukuna should know Reverse Cursed Technique," he mused aloud.
[Stupid question.]
"Reverse Cursed Energy is Yang, and Cursed Energy is Yin. Together they form..." Cid trailed off as a solution began to form in his mind.
"Convergent Yin-Yang combination," he muttered. Attempting to execute it, his hands suddenly burned away—not scorched, but completely erased from existence.
"AHHHHHHHH!" Cid screamed, his eyes watering from the excruciating pain.
[If it were that easy...]
"Don't mock me!" Cid snapped, glaring at his arms—or where his arms had been. To his relief, they began to regenerate, though the process was slow and agonizing.
"Hmm, you're right—it's not that simple. But now I've got another problem: how the hell am I supposed to graduate? I need to learn the Clone Jutsu for that. I'm not staying in the academy forever," he grumbled.
[Don't ask me. I'm just as clueless as you are.]
"If I can't create a clone using Yin Chakra, I'll find an alternative," Cid muttered, smirking as an idea struck him. He thought of a certain bag-wearing sorcerer from Jujutsu Kaisen.
"Hey, you said I could have more than one cursed technique, right?" he asked.
[Yep. You need to earn Spins for that. Spins let you choose from three options. Right now, you have zero. Complete quests to earn Spins.]
"Alright, then give me a quest," Cid demanded.
[No.]
"..."
