Darkness.
Cold, formless, and infinite.
That's all Yuu Takahashi knew in the moment after his death. One second, he was just an average seventeen-year-old high schooler walking home with a half-eaten melon bread in one hand and his phone in the other, laughing at a Jujutsu Kaisen meme. The next?
Truck-kun did what Truck-kun does best.
Not even dramatic. No slow-motion. Just lights, pain, and… silence.
Until a glowing blue screen floated in the darkness before him.
> Welcome, Yuu Takahashi.
You have been selected by the Absolute System.
[Click Here] to be Reborn in a New World.
Warning: Your very existence may shatter balance. Proceed anyway?
He blinked. "This… isn't a joke?"
No voice replied. Just the screen, pulsing softly.
"Well, I always said if I got isekai'd, I'd break the world. Let's go full protagonist mode."
He reached forward.
> [Click]
The moment his finger touched the virtual button, his entire being dissolved. His senses collapsed. His thoughts were stripped away and remade.
Light returned. Heat. Air. A heartbeat.
Then—
A gasp.
Yuu sat up violently, drenched in sweat, lungs heaving like he hadn't breathed in years. He was lying on a wooden floor inside what looked like a dormitory room—simple tatami mat, sliding doors, and a full-length mirror in the corner.
Except… this wasn't his body.
He scrambled to his feet and stared at the mirror. Taller. Sharper jawline. Muscular. His hair was longer, slightly spikier, and his eyes glowed faintly with cursed energy.
And then came the voice. Calm. Robotic.

His body pulsed with unnatural power. His fingertips shimmered with cursed energy. His brain flooded with information: Rika's monstrous love, Gojo's Limitless, Sukuna's Malevolent Shrine — he knew all of it now. It wasn't just knowledge; it was instinct.
"I'm a walking nuclear bomb," he muttered, awestruck. "No… worse. I'm a main character on steroids."
Footsteps approached from outside.
Yuu tensed instinctively, though his new power calmed him. Whatever or whoever it was, he could flatten them with a glance if he wanted.
The sliding door opened with a sharp snap.
A girl stepped in — tall, orange hair pulled into a loose bun, golden-brown eyes narrowed in irritation. She was wearing a Jujutsu High uniform, her black skirt swaying as she stepped forward.
"You the transfer?" she asked bluntly.
Yuu blinked. Nobara Kugisaki. Early. Pre-canon. Maybe a year or two before her manga debut.
"Yeah," he said, composing himself. "Yuu Takahashi."
She stared at him a little too long. Her gaze wasn't hostile, but there was something… intense in it.
"I see," she said finally. "You smell weird."
"…Weird how?"
She tilted her head, her gaze darkening just slightly. "Like power. Like someone who shouldn't be here yet."
Before he could answer, her expression suddenly brightened.
"I like it."
She reached behind her back. A hammer gleamed faintly in her hand. "Let me test how strong you are."
Yuu held up both hands. "I'm good. Really. Let's save the sparring until I've had lunch."
Nobara frowned. "You're no fun." But she didn't lower her hammer.
Instead, she took a step closer. Too close.
"Are you single?" she asked, casually.
"What?"
"You're kinda cute, and I get the feeling someone's going to try to kill you soon. I'd rather stake my claim first."
Yuu stared. The System chimed again.
> Yandere Threat Detected.
Target: Nobara Kugisaki
Status: Early Infatuation (High Risk)
"Oh no," Yuu whispered.
Nobara smirked. "What was that?"
"Nothing."
She smiled wider and leaned in, her breath brushing his neck. "You smell like a curse I could fall in love with."
Yuu backed up slowly. "Can you… not?"
Too late.
From the hallway, another voice called out. Female. Cold. Clinical.
"Is that the new student?" the voice said.
Shoko Ieiri stepped into view, hands in her lab coat pockets, eyes like dead stars.
She saw Yuu.
And her lips curled into something dangerously close to a smile.
"I think I need to do a full checkup," she said softly. "Alone."
The System beeped again.
> Double Yandere Alert. Prepare for Impact.
