The last thing Haruto Shin remembered was the headlights.
Two bright circles burning through the rain like the eyes of some hungry beast. Then the horn. Then nothing.
Well not exactly nothing.
There was a moment, somewhere between the impact and whatever came after, where he felt his entire body go weightless. Like floating in warm water. Peaceful almost.
Then he hit the ground.
"AGHH—"
His back slammed against cold wooden floor so hard that his teeth rattled. His eyes shot open to a ceiling he didn't recognize. Old wood. Water stains. A single lightbulb hanging from a wire that looked like it hadn't been replaced since the 90s.
He tried to sit up.
His arms shook. Not from pain but from weakness. Pure pathetic weakness. Like his muscles had been replaced with wet noodles.
"What the..."
He looked at his hands. Thin. Pale. The veins were visible under skin that hadn't seen sunlight in months. These were not his hands. His hands were rough and calloused from years of boxing in college. These hands looked like they'd struggle to open a bottle cap.
He forced himself to sit up and immediately regretted it. His vision swam. The room tilted sideways and he had to catch himself on the edge of a futon that smelled like dust and cheap detergent.
A futon.
He was sitting on a futon. In a tiny room with tatami flooring and sliding doors. The kind of room you'd see in a Japanese apartment from some old movie.
"Okay." He pressed his palms against his face. "Okay okay okay. I'm dreaming. This is a dream. I got hit by a truck and now I'm in a coma having the weirdest dream of my life."
He pinched his arm.
It hurt.
He pinched harder.
It hurt more.
"Not a dream then."
His eyes scanned the room desperately. A small desk with a laptop. A phone charging on the floor. Some textbooks stacked in the corner. A calendar on the wall.
The calendar was in Japanese.
He could read it.
He should NOT have been able to read it. Haruto Shin was born in Detroit. He spoke English and enough Spanish to order food. That was it. Japanese was absolutely not in his skill set.
But he could read every character on that calendar like he'd been doing it his whole life.
His breathing got faster.
He grabbed the phone from the floor. The lock screen showed a date.
October 15th.
And a reflection.
The face staring back at him from the dark screen was not his face. It was younger. Maybe twenty. Japanese. Messy black hair that fell over dark eyes. Sharp jawline but the kind of skinny that said this body survived on convenience store rice balls and anxiety.
Not ugly. But fragile. Like a strong wind would snap this body in half.
"I'm—" He swallowed hard. "I'm in someone else's body."
That's when the blue light appeared.
It started as a tiny spark in the corner of his vision. Like a notification popup from a phone. Then it expanded into a translucent blue panel floating in the air directly in front of his face.
[SYSTEM INITIALIZING...]
[WELCOME, HOST]
[YOU HAVE BEEN SELECTED FOR THE TRAINING GACHA SYSTEM]
[CURRENT STATUS: PATHETIC]
"Did the system just call me pathetic?"
[ASSESSMENT IS ACCURATE. YOUR CURRENT PHYSICAL STATS ARE BELOW AVERAGE CIVILIAN LEVEL.]
[STRENGTH: 3/100] [SPEED: 4/100] [ENDURANCE: 2/100] [CURSED ENERGY: 0/100] [CHARM: 47/100]
He stared at the panel for a full ten seconds.
"My charm is my highest stat?"
[HOST HAS AN APPEALING FACE AND NATURAL CONVERSATIONAL ABILITY. SYSTEM RECOMMENDS LEVERAGING THIS.]
"Leveraging my charm. In a body that can't do a pushup."
[CORRECT.]
He fell back onto the futon and stared at the ceiling. His mind was racing. System. Gacha. Cursed energy.
Cursed energy.
He knew that phrase. He knew exactly where he'd heard it. Every Sunday night for three years sitting on his couch watching anime and reading manga on his phone.
Jujutsu Kaisen.
He shot back up so fast his head spun.
"No. No no no no no."
He scrambled to the desk and opened the laptop. The browser history confirmed everything he didn't want to know. Tokyo Metropolitan Jujutsu Technical High School was listed in the bookmarks. This body's previous owner had been researching jujutsu sorcerers.
He grabbed the calendar again. October 15th.
His brain did the math faster than his body could keep up with.
The Culling Game. Kenjaku's masterpiece. The event that turned Japan into a death tournament where ancient sorcerers fought modern ones for points. Where people died by the hundreds. Where even Gojo Satoru—
Gojo was still sealed.
No wait. What timeline was this? Before the sealing? After?
He checked the laptop again. Shibuya Incident. It had already happened. The news archives were full of the cover story about the "terrorist attack" in Shibuya. Gojo was sealed inside the Prison Realm.
Which meant the Culling Game was coming.
And based on what he remembered from the manga the activation was roughly—
"One month." His voice came out hollow. "I have one month before the entire country turns into a death game."
He looked at his stats again.
[STRENGTH: 3/100] [CURSED ENERGY: 0/100]
"I'm going to die."
[SYSTEM RECOMMENDATION: DO NOT DIE.]
"Oh thanks. Real helpful."
[THE TRAINING GACHA SYSTEM EXISTS TO GIVE HOST A CHANCE AT SURVIVAL. WOULD YOU LIKE TO HEAR THE TUTORIAL?]
Haruto sat cross legged on the futon and rubbed his temples. He had exactly two options. Panic and die. Or listen to the magic floating rectangle and maybe not die.
"Fine. Hit me with the tutorial."
[TRAINING GACHA SYSTEM — OVERVIEW]
[THE SYSTEM REWARDS HOST FOR TRAINING OTHERS.]
[EACH TRAINING SESSION EARNS POINTS.] [POINTS CAN BE USED FOR GACHA PULLS.] [GACHA PULLS GRANT ITEMS, ABILITIES, AND KNOWLEDGE.]
[TRAINING BONUS: FEMALE SORCERERS GRANT 3X POINT MULTIPLIER.]
He read that last line three times.
"Why... why is there a multiplier for women?"
[SYSTEM DOES NOT EXPLAIN DESIGN PHILOSOPHY. SYSTEM ONLY PROVIDES RESULTS.]
"So you're telling me I get triple rewards for training girls?"
[CORRECT.]
"This system was designed by a pervert."
[SYSTEM DOES NOT RESPOND TO PERSONAL ATTACKS.]
He leaned back and actually laughed. The first real laugh since he woke up in this body. It was absurd. All of it. He died in Detroit hit by a truck and now he was in Japan inside a stranger's body with zero cursed energy and a system that wanted him to be a personal trainer for female sorcerers.
But underneath the absurdity something clicked in his brain. The part of him that used to watch JJK and scream at his phone because the female characters deserved better.
Maki Zenin. A beast with weapons who never got to reach her full potential until tragedy forced it.
Nobara Kugisaki. A fan favorite who got sidelined at the worst possible moment.
Utahime Iori. A semi grade 1 sorcerer that everyone forgot existed.
These women were powerful. More powerful than most sorcerers in the story. And in the canon timeline they either died too early or peaked too late or just never got their moment.
But if he trained them BEFORE the Culling Game...
"System."
[YES HOST?]
"If I train them before everything goes to hell... they could change the entire outcome. Right?"
[THE TRAINING GACHA SYSTEM DOES NOT PREDICT OUTCOMES. BUT HOST'S LOGIC IS... NOT TERRIBLE.]
"That's the nicest thing you've said to me."
[WOULD YOU LIKE TO BEGIN? YOUR FIRST TASK HAS BEEN GENERATED.]
A new panel appeared.
[FIRST TASK: REACH JUJUTSU HIGH WITHIN 24 HOURS] [REWARD: 100 POINTS + FIRST FREE GACHA PULL] [PENALTY FOR FAILURE: SYSTEM DEACTIVATION]
"System deactivation? You mean if I don't get there in time you'll just... leave?"
[CORRECT. SYSTEM HAS MANY POTENTIAL HOSTS. YOU ARE NOT SPECIAL.]
"Wow. The motivation is incredible."
He stood up. His legs wobbled like a baby deer taking its first steps. He caught himself on the wall and took a breath.
Outside the window Tokyo stretched out gray and massive under a cloudy sky. Somewhere in that city was Jujutsu High. Somewhere in that city were sorcerers who could kill him by accident. Somewhere in that city Sukuna was sitting inside a teenage boy waiting for his chance to burn everything down.
And here was Haruto Shin. Twenty year old nobody. Zero cursed energy. Strength stat of 3.
But charm of 47.
"Alright Tokyo." He grabbed a jacket from the closet and shoved the phone in his pocket. "Let's see how far charm gets me before something eats my face."
[TIMER STARTED: 23:59:48]
[GOOD LUCK HOST.]
[YOU WILL NEED IT.]
