His Little sister

Excuse Me?!

Megumi just stared at me, not showing any signs of emotion. "So you know our names? Isn't it rude that you aren't introducing yourself?"

"Touché." The corners of my lips twitched upwards slightly. "Y/n." I held my hand out for him.

He cautiously grabbed my hand, meeting me for my handshake. "Just Y/n?" He raised a brow.

I nodded, releasing his hand. "I prefer my first name. I can't stand my last name."

He nodded, clearly understanding. "Why are you here?"

"Oh right. I'm a new first year. I keep forgetting I don't exactly have a school uniform. I just wear my exorcism outfit."

(Imagine whatever you want for your professional outfit and uniform. This is made for your imagination. I won't make this into an oc. So please enjoy!)

"Exorcism outfit?" Itadori looked at me confused. "Why would you have one of those already if you're a student?"

I looked away, not really sure if I should explain my situation. And frankly, I didn't really want to cuz I don't want anyone to know that Satoru is my older brother. "Reasons."

The three first years still looked somewhat suspicious of me. Kugisaki stayed tense. "How do we know you're not a curse user or something?"

I glared. "Listen here, bitch. I'm a full-fledged sorcerer, and a special grade at that. But I'm the same age as you, and wanted to try interacting with more people my age instead of traveling all the time and only dealing with adults. So shut the fuck up and don't comment on things you don't know or don't understand."

I felt a hand on my shoulder, a terribly familiar voice came from behind me. "Now now, Y/n. Don't start picking fights with all the female students on your first day."

I activated my Infinity, pushing him away. "Don't touch me, creep." I turned to glare at my brother.

"You can't get along with anyone for shit. So not a people person. But you're powerful, so wonderful asset I guess." He turned to his other students. "Meet Y/n. She can be pretty bitchy but is a great sorcerer and is close to many of the adults you'll either see or work with. She's been a sorcerer since... well, since I was still a student here!"

I turned back to my new classmates, focusing on Itadori. "I heard you have control over Sukuna and have impressive physical abilities without relying on cursed energy. That's pretty cool, dude."

"At least try to put some emotion into your voice, ice princess. No one will believe a word you say if you sound so empty." Satoru bluntly commented.

"Don't talk to me, don't touch me, don't even look at me if you value your life at all." I coldly replied.

Megumi chuckled. "Don't like Gojo?"

You mean myself or my brother? Or the rest of my family/clan? Cuz the answer is no to all of that. "Hate him."

"Mean!" The big baby himself complained.

I rolled my eyes. "So immature and irresponsible. And for what?"

Megumi laughed, trying to hide and stifle it with his hand. "Oh, I like her. We'll get along just fine."

Heart go 📈
Stomach said 🦋🦋🦋

This dude will be my baby daddy. "Bet."

"This was a mistake."

I snickered at my overwhelmed older brother. "Your fault for not being a good adult and teacher."

Megumi snickered beside me. "How did they even let him teach?"

"He only got in so it keeps him out of trouble. And cuz he just happens to be one of the strongest sorcerers." I slightly leaned against his arm.

Satoru turned to us and frowned. "Stop being mean or I'm having them ship you to outer space!"

"Do it then. I wanna get as far away from you as possible." I stuck out my tongue.

"Good. I'll call the higher ups now."

I laughed. "You hate them and I know you won't do it! So shut the fuck up, you overpowered, egotistical, horny, perverted, irresponsible, overrated, self-centered baby."

He glared under his blindfold. "I hate you. Put a damn blindfold on so I don't have to see the majority of your face."

I rolled my eyes. "Wrap your ugly face in bandages again so I won't have to see it."

"You two have history?" Kugisaki interjected curiously.

I cringed in disgust. "Oh my fucking god, NO!"

Satoru frowned. "She's the last person I'd ever think about, in that way. Doesn't mean o don't love you princess."

"Wait a minute while I go throw up." I started dry heaving away from them.

"So rude, and for what?" My older brother crossed his arms over his chest.

"Cuz I hate you and your whole clan."

He deadpanned. "It's your clan too?"

"Nah. Don't know em."

Megumi flinched. "You're a Gojo too?"

I sighed, hanging my head. "Unfortunately."

Satoru whined. "Mean! You're my baby sis but you're so mean!"

"Excuse me?!" The other three first years exclaimed.

I rolled my eyes. "Yeah yeah. You're just not big brother material."

Satoru wrapped his arms around me in a tight hug. "My baby sis is just grumpy! Who needs a hug?!"

I wriggled in his arms. "Let! Me! Go!"

"No!" He began giving me brotherly kisses on the top of my head.

I screeched. "EEWWWW! DONT TOUCH MEEEEEEEEEE!" I used my Infinity and pushed him off, sending him flying.

He landed on his back, sprawled on the ground. "That hurt!"

Megumi frowned. "Are you really Gojo's little sister?"

I nodded, still looking unhappy. "Don't like it, but I am."

He turned away from me, his back facing me. "Don't talk to me, touch me, or get in my way."
