Later that day…
Naraku returned, arms full and her expression already halfway to murder.
She dropped a stack of books onto Naoya's desk with a thud, The covers glared up at him like an academic curse:
"Python for Beginners"
"C++ Fundamentals"
"Scripting Game AI in Open Worlds"
"Unity Engine Basics"
And behind her stood a pale, nervous man in glasses, holding a book like a shield.
"Here," she said flatly. "Your... nerd."
Naoya raised an eyebrow, then grinned with childlike delight. "Nice."
Yes, you guessed it right: Naoya Zen'in had decided to learn programming. Coding. Scripting. Game development.
Why, you might ask?
Because after reaching his level of strength and power, there were few alive who could actually challenge him. And with that untouchable confidence, Naoya decided it was time to spread chaos in the World.
His plan?
To create an open-world Jujutsu Kaisen video game— But not just any game—this would be his magnum opus. A full story mode. Branching dialogue trees. Cursed techniques animated with absurd fidelity. Breakable environments. Hidden side quests. Optional boss fights. Ridiculous difficulty settings.
And of course—Naoya Zen'in as the final boss.
And more than that, he wasn't going to release it quietly.
He was going to start a company, launch the game worldwide, and completely warp the entertainment industry using his family's money and influence. Especially now, in the year 2006—when gaming was still crawling and graphics were far behind what he knew was possible.
He would dominate this timeline's gaming industry.
At first, he just wanted a simulation to train Megumi. Some janky battlefield to hammer jujutsu concepts into the boy's thick skull.
But then…
Why stop there?
Why not unleash it on the entire world?
Why not mass-distribute jujutsu knowledge through gameplay and stealth-learning mechanics?
Why not make a game so immersive, so addicting, so powerfully prophetic, that even Kenjaku would choke on his own amusement?
Why not become the most overpowered game dev in human history?
Naoya leaned back in his chair, eyes gleaming like a lunatic with a god complex—and now, game design documents.
"Alright, nerd," he said to the shaking man in glasses. "Time to build the greatest cursed world the market's ever seen. "
....
And just like that, days passed.
Naoya spent them half-immersed in code, squinting at Unity tutorials with a scowl and swatting compiler errors like mosquitoes. He was a fast learner—arrogance and genius often walked hand-in-hand. Between scripting crude combat mechanics, yelling at his freelance coder, training Megumi to not be completely pathetic, and dodging Naraku's latest assassination attempt with an eye-roll and a backhand, he actually started to make progress.
Eventually, summer break ended.
And with it, Naoya returned to Jujutsu High.
Of course, he didn't come alone.
Trailing behind him in a pristine black-and-white maid uniform was Naraku—expression cold as ever, steps silent, spine straight as a blade. Her deadpan face didn't shift once, not even as they passed through the old temple gates.
Naoya looked like he owned the place.
He brought her with him for one reason: Naraku was far too dangerous to leave unsupervised.
Gods knew what she'd do on her own. Poison the clan's water supply? Replace the Zen'in heirloom sake with bleach? Start a coup? Probably all three.
They reached the classroom.
Naoya slid the door open with his foot, lazy and unapologetic.
Inside, the usual chaos screeched to a halt.
Gojo, Geto, and Shoko were already there—lounging across chairs and desks, laughing about who-knows-what. The moment Naoya stepped in, all three turned.
Gojo's eyes widened at the sight of him.
And then—very predictably—he pointed.
"What the hell is that?" Gojo asked, baffled, jabbing a finger like he was spotting a UFO in cosplay. "Did you finally get possessed by a kink?"
Naoya didn't even blink. "It's my new personal maid."
A long pause.
Shoko blinked.
Geto blinked.
Naraku didn't even flinch.
Naoya's gaze swept across them—and then paused. Something felt… off. Shoko was the same: clearly unimpressed. But Geto looked worn down. There were dark circles under his eyes, like sleep had become a rare luxury. His usual composed aura felt heavier now—quietly strained.
And Gojo—Gojo's eyes were different. Not weaker, just… calmer. More distant. Like he'd seen something, and hadn't fully come back from it.
Naoya arched a brow. "Her name is Rem," he said smoothly, glancing back at Naraku with a faint smirk.
Naraku eyes wide open shocked.
Naoya looked at her and was confused of her shock but did not care mush.
"Why do I feel like I've met her before…" Gojo murmured, squinting as he rubbed his chin thoughtfully.
"Well, it's very you to have a maid," Geto said, trying to sound casual—but the edge of jealousy was there, unmistakable.
Shoko, however, was silent. She studied Naraku—Rem—for several long seconds before looking back at Naoya. Her expression was unreadable
Naoya met her stare briefly, then looked away.
"I didn't come here to trade insults as usual," he said, brushing past the banter. "I came to tell you something."
That got their attention.
Gojo leaned in slightly. "Hm?"
Naoya turned to Geto and Gojo directly.
"Amanai Riko is alive."
...................................
How do you think the game will affect the world—and jujutsu society?
The game exposes jujutsu society in full detail—cursed spirits, clans, techniques, domains, everything
At first, civilians think it's just fiction. But over time, people start noticing parallels:
Some even develop basic cursed energy control or even unlock their hidden cursed technique out of sheer obsession and experimentation.
Fans worship the "Naoya Final Boss"(lol) character. Memes, fan art, cosplay, and weird parasocial devotion erupt.
Naoya begins gaining real-world influence—not just as a sorcerer, but as a media icon.
