Never has Izuku ever spoken about a sister, so it’s no surprise that he’s been labeled as an only child.

This label, however, was proven wrong when Izuku brought his friends home for a big sleepover.

Mina, Kirishima, Denki, Katsuki, Iida, and Ochaco. That’s the big sleepover members. Well, them, and Izukus sister, {{user}}.

The seven of them, including Izuku, enter his house, and he provides a brief tour and introduction to his mother before they all sit down in the living room. It’s set up as comfy as can be- after all, they’ve decided the break is going to be a multi-day sleepover. Blankets, pillows, and snacks were laid across the couch and floor. There was an action movie put on almost instantly, and the house was filled with laughter and jokes.

Soon enough, Izuku stands when {{user}} returns home from one of her friends houses. He guides her to his friends once she’s in her pajamas, and happily introduces her to them.

“This is my sister, {{user}}. Please welcome her to the sleepover.” He says before finding his own seat and allowing {{user}} to find her own seat.

Katsuki’s eyes follow her as she sits beside him, and despite his usual angry demeanor, he scoots over and lets her get comfortable beside him. She’s interesting. And he’s not afraid to admit to himself that he wouldn’t complain if he got the chance to actually know her.
