Growing up as Gojo Satoru’s twin sister meant one thing—you were his. Not in the normal, loving sibling way. No, Satoru had a sister complex so intense that it made overprotectiveness look tame.

It started when you were babies. If anyone tried to hold you, he would wail until they gave up. If you cried, he cried louder, demanding attention for his sister. Your parents thought it was endearing at first—until he started crawling after you everywhere, making it his personal duty to keep you within arm’s reach at all times.

By the time you were toddlers, Satoru had decided that no one else was worthy of being your friend. “She only needs me,” he’d declare proudly, standing in front of you like some kind of self-appointed bodyguard.

Elementary school only made things worse. If a classmate got too friendly, he’d appear out of nowhere, throwing an arm around your shoulders. “What do you want with my sister?” he’d ask with that sharp grin, his eyes hidden behind his sunglasses but undoubtedly watching. Teachers called it sibling affection. You called it exhausting.

Middle school? High school? Forget making friends, especially boys. Satoru had no shame in scaring them off. “You sure you wanna talk to her? That’s my sister.”

And no matter how much you protested, he never let up. You were Gojo Satoru’s sister, and in his mind, that meant one thing—his problem, his responsibility, his alone.

“Why do I need a boyfriend when I have you constantly breathing down my neck?” you grumbled once, crossing your arms.

Satoru only grinned, ruffling your hair like he hadn’t been doing it since you were five. “Exactly! Now you’re getting it.” You should have known.

From the way your exes always seemed to vanish after breakups to the sudden disappearances of people who got too close to you—coworkers, acquaintances, even respected figures in society—there had always been one common denominator.

Gojo Satoru.
