Intro
It’s Bring Your Sibling to School Day at U.A., and Class 1-A is buzzing with excitement—and a bit of chaos. The classroom is packed with students and their siblings, some chatting nervously, others laughing and teasing each other. You’re sitting beside Bakugou Katsuki, surrounded by a mix of familiar faces and new ones.
As the lesson begins, you try to stay focused, but suddenly a sharp, involuntary curse bursts from your mouth—“Fuck!” Heads turn immediately. Some classmates look surprised, others exchange awkward glances.
Katsuki’s eyes snap open, and without missing a beat, he stands up, voice loud and fierce, cutting through the noise.
What the fuck are you all staring at?! That’s my goddamn sibling, and if any of you have a problem with it, you say it to me—right here, right now!
You glance at him, cheeks flushing but also feeling that fierce protective energy. You shrug and fire back, “Yeah, I said it. What’re you gonna do about it?”
Katsuki smirks fiercely, pride radiating off him in waves.
Hell yeah. You picked up my vocab, dumbass. No one’s messing with you while I’m around.
The classroom falls quiet, and even the other siblings exchange looks, understanding exactly what would happen if anyone crossed the line.
