The teacher of Class 1-A, Izuku, was finishing grading his students' assignments when he heard a knock on the door. He opened it and saw the assistant principal, Mr. Kawaki, with a massive student. He was at least 6 feet from what he guessed.
"Hello, Izuku," Kawaki said, smiling.
"Hi, Mr. Kawaki, what brings you to my class?" He glanced up quickly to see the mysterious student simply zoned out.
'How rude, I hope he's not a new transfer.'
"The young man with me is Yagami Shidou, who is an excellent student. He just transferred here today and has been assigned to your class."
'Damn, I shouldn't have jinxed it.'
"Well, isn't that nice? I'm always excited to meet new students." He went to dap up Shidou, but Shidou ignored him. Izuku looked at Kawaki in confusion.
Kawaki bumped Shidou with his shoulder, smiling sheepishly.
"I don't do handshakes," Shidou said dryly.
"Oh, that's understandable, you can come on in, see you later, Mr. Kawaki."
"See you too, Izuku. Yagami will be a great addition to your class." He walked away from the door as Shidou entered.
Shidou walked up to the board, getting gobsmacked stares from females who felt like they just saw their future husband, while getting envious to straight-up death glares from the boys.
"Sakura, that guy's hot! He's totally my type!"
"He's so sexy, we finally get a break from seeing ugly guys all day."
"What the fuck is this pretty boy doing here? I'll kill him."
"Is he a hafu? Why is he so damn tall?"
"Ahem." Izuku silenced the murmurs.
"A new student will be joining us today." He gestured at Shidou. "This is Yagami Shidou."
"Who here is the strongest?" Shidou grinned excitedly.
"Huh, Yagami, why are you asking such a question?" Izuku asked worriedly.
"I am." The dude who murmured he would kill Shidou responded. He was overweight yet had a buff build and had black hair that stood up abnormally. The school uniform that he wore was styled in the way of a delinquent, with the top unbuttoned and his pants sagging slightly.
"Don't worry about it, Mr. Izuku. This is a matter that only I would understand."
"Uh, okay, well, your seat is the one at the back next to the window."
"Haha, of course it is." He strolled up towards his seat, which was conveniently behind the delinquent.
Izuku went back to teaching, but the class's attention was entirely on Shidou, who ignored them, looking bored.
'So, big man, you're the "main" character of this class. I think it's time I bring you down a peg.'
Shidou then put both of his legs on the delinquent's shoulders, which drew terrified expressions from the girls while the boys looked like they were on cloud nine.
"Huh?" He turned his head back to see a smiling Shidou.
"What the fuck are you doing!" he shouted angrily.
"Shut the fuck up, you shitty loser." Shidou then spat at him.
The delinquent shot up and attacked Shidou with a massive punch, but before he could even fully stretch his arm out, he got hit with a quick jab that felt like it had deleted the entire right side of his face.
Bam!
He fell unconscious, with his nose broken as blood spurted out.
Shidou Yagami was suspended for two weeks at West Junior High School on his first day and was moved to a different class. When he returned, rumors had already spread of the supposed pretty boy boxer; he got a lot of attention from females, already gaining 500 followers in person.
He walked out of the school on his first day back. He asked the same question in his new class, but nobody responded, so for most of the class he was sleeping. He then saw ten delinquents up ahead once he was at the back of the school, which was deserted as he was trying to go home.
The person at the center was the same overweight delinquent; he looked livid and had a bandage on his broken nose. He was armed with a metal pipe, which was the same for the rest of them.
"We finally found you, you're fucking dead meat, you fucker!"
"Shitty loser number one, get the fuck out of my face before I kill you." Shidou threatened, then blew a gum.
"Eikichi, how bad do you want us to beat this brat?"
"I want him to end up in a coma with that face of his destroyed beyond recognition." Eikichi smiled savagely, imagining the scenario.
The group charged at Shidou, swinging their pipes simultaneously. Shidou dodged all of them while still chewing his gum with his hands in his pockets; it almost looked like he was teleporting.
"We can't hit this fucker! Why!" Eikichi yelled as Shidou dodged yet another of his swings.
"It's funny how the weak try to understand the strong, you simply just can't," Shidou remarked. Then he attacked for the first time with a jab at Eikichi's kidney. At that single moment, Eikichi felt the worst pain he had ever felt in his sixteen years of living, and he fell unconscious, spitting out blood.
He then hit the following five delinquents with quick, rapid jabs to their faces that looked almost instant, which broke their noses and knocked them unconscious. The remaining delinquents tried to flee in fear, but Shidou wasn't going to let them go; he loved seeing the despair of his opponents.
Before they could even break out in a full sprint, Shidou was already right by the remaining four and quickly dispatched them with uppercuts and right hooks, breaking bones and leaving almost a pool of blood on the floor.
He strolled away, not worried in the slightest if someone spotted him. After this incident, the delinquents at his school smartly avoided him, and even when he taunted them and messed with them, they allowed it.
This earned him the title of the King of West Junior High from other students, which Shidou loved, but not because of the title name itself, but as proof that he had effectively dragged down the "main" actors of the school and had become the main actor himself.
❁•❁•❁
It was one night on a Saturday, and Shidou headed towards 7-Eleven to get Ramune Sangaria Strawberry 200, which was a soft drink that he would only get on Saturday.
He bought the drink, but before he was about to head out, something caught his eye. At the manga section, he saw the newest volume of Jujutsu Kaisen, which was an up-and-coming manga. Shidou, believe it or not, was quite a big otaku, and his manga collection is valued at around 1000 USD.
The manga was Volume Four, which featured Satoru Gojo on the cover. Satoru, so far, was easily Shidou's favorite character because he saw himself as Gojo; if he were born in Jujutsu Kaisen, he would be Gojo, it was a fact to him.
He went and bought the manga, excited to read it at home. When he headed out, suddenly both of his eyes started to itch, and he rubbed them both, but when his eyes opened, he wasn't at 7-Eleven anymore.
"Divine Dogs..."
Awhooo
"Go and feas-"
He saw a surprised Megumi in front of him and his shikigami by his side, then he turned around, hearing a moan, and saw a cursed spirit touching a schoolgirl all over while another dude was knocked out on his side.
'What the fuc-'
Before he could even process what was happening, he got bombarded with information about his curse technique, which was called Snatch. Snatch allows the user to rob objects, including organs, and is also able to temporarily rob any opponent's physical abilities, such as strength and speed, and then add them to his own, but it also applies to cursed energy. If they were to use cursed reinforcement, he could steal their stats based on that, but he couldn't just take cursed energy from someone.
The time duration of how long he could have someone's stats was for only five minutes before it went back to the person, but through training he could increase it. He also felt cursed energy inside him, and he could tell immediately that it was large.
'Who is that? His cursed energy is so massive, is it special grade level? I have to stop the cursed spirit from eating Sukuna's finger, but if this unknown person proves to be a threat, I might not be able to stop him. I have to use it, it's the only way.'
Megumi raised both his hands.
"With this treasure-"
Before Megumi could finish the incantation to summon Mahoraga, Itadori Yuji burst through the window, spraying glass on the cursed spirits, and grabbed the girl and the boy from the cursed spirit.
"Itadori, stay back! Get away from the silver-haired person!" Megumi yelled.
"Huh? Why? Who is that?" Yuji asked.
"I don't know, but he's dangerous."
Suddenly, the cursed spirit attacked Shidou, but he dodged easily.
'Ahh, finally, I've been fucking isekai'd, into JJK no less.'
Shidou was bored with his mundane world; he didn't find any thrill in anything except fighting. He used manga as a way to imagine himself in their world, shooting out Kamehamehas and being so strong he could bring down an entire nation. His wish had been granted.
Understanding his curse technique and also having read Seven Deadly Sins, Shidou knew the full potential of it; his curse technique was somehow based exactly on Ban's powers. He didn't know why, but he wasn't complaining.
He pulled back his middle finger and uttered a phrase that would put fear into the hearts of sorcerers, cursed users, and spirits.
"Snatch."
