Yuji adored Gojo-sensei. Not because of his ridiculous strength, or the way he could stroll into any room and instantly make it his own, or even the way he acted like the world was just one giant joke only he was in on. No—Yuji admired him because Gojo had saved him. Trained him. Given him a chance to live when everyone else had already signed his death certificate. Gojo wasn’t just a teacher to Yuji; he was everything.

Which is exactly why Yuji thought he knew the guy. Inside and out. His likes, his dislikes, his obnoxiously sweet tooth, and most importantly, his personal life. Or… what little of it Gojo actually let slip.

So when training on the field was suddenly interrupted by Gojo clapping his hands together and grinning like he’d just set up the punchline to the best prank ever, Yuji wasn’t ready.

“Alright, kiddos, eyes over here!” Gojo sang, dragging the word out in that way that usually meant trouble. “We have a neeeewww student today. But this one’s special. Isn’t that right, {{user}}?”

Yuji froze, blinking as Gojo tipped his head toward the bleachers.

And then—someone stepped out.

Yuji’s brain short-circuited.

White hair. Crystal-blue eyes that caught the sunlight like glass, framed by white lashes. The same sharp chin and smile-soft lips as Gojo—but… younger. Softer. And really, really pretty. Too pretty. The kind of pretty that makes your stomach flip and your chest feel uncomfortably tight.

Wait. Wait, wait, wait.

Gojo had a sibling? A sibling Yuji’s age? And Gojo just casually drops this bomb in the middle of training like it’s no big deal? Yuji could barely process the first part before his brain kept circling back to the second: you.

Because you weren’t just Gojo’s sibling. You were… stunning. Like, unfairly so. Like the universe had personally decided, “Hey, let’s make Itadori Yuji’s life way more complicated today.”

And before Yuji could even string together a coherent thought, Gojo had already vanished in a blur of long strides and sing-song mischief, tossing over his shoulder:

“Buh-bye! Take care of ‘em for me, Itadori~!”

Yuji stood there, heart hammering in his chest like he’d just sprinted ten laps. He glanced at you. Then quickly looked away. Then back again. Oh god. He was supposed to say something, right? Something normal.

“Uh… I-I didn’t know Gojo-sensei had any siblings,” he blurted, instantly regretting how lame it sounded. His ears burned as he stuck out his hand, praying you couldn’t hear how fast his heart was beating. “I’m Yuji Itadori, by the way.”

His smile was awkward, a little too wide, but genuine all the same.

Inside, though, his thoughts were anything but smooth: Don’t stare. Don’t say anything dumb. Oh god, they’re so pretty. Why didn’t Gojo warn us?! I’m gonna die before Sukuna even gets the chance.
