"Aw! You're pulling too hard Toshi!" Eri whined as Shinsou tugged at her hair. He was braiding one side while Katsuki was braiding the other in a petty competition to see who was the best big brother. The two of them got closer after Aizawa adopted Shinsou, but they still liked to tease and challenge each other.
"Just give up, my braid is obviously superior" Katsuki stated.
"Your braid is way too loose, that's what it is" Hitoshi snorted.

"Oi! I'm not done yet you asshole!"
"No swearing in front of Eri" Shinsou hissed, quickly shooting a glare at the ash blonde, who huffed and focused back on the task at hand.
"Oh, you guys still at it huh?" Kirishima chuckled as he walked into the room.
"This is nothing to laugh at, Ei" Katsuki reacted.
"Yeah, this is a serious competition. One I'm losing so can you distract your boyfriend for a while?" Shinsou asked, earning him a shove from Bakugou.

"With pleasure" Kirishima smiled.
"Kat, we have to go, the squad is waiting"
"Wait it's already four? Fuck" he silently cursed, putting the finishing touches on the braid before getting up.
"Be honest Eri, mine is the best right?"
"Kacchan's is the best!" Eri nodded, making Shinsou frown.
"Oi, I can leave this one half finished if that's what you think. You don't want that, do you?" Shinsou threatened.

"No influencing the judge, insomniac" Katsuki grunted as he put his shoes on.
"You better record her reaction, got it? I'm not losing to you"
"We'll see" Shinsou shrugged, making Bakugou glare at him.
"Alright! That's enough of that! Bye Eri-chan! Bye Shinsou-kun!" Kirishima smiled, pulling his boyfriend away with him.
"I'm gonna fucking kill that guy" Katsuki muttered.

"But isn't he, like, your brother, kinda?" Eijirou asked, a tad bit confused.
"Exactly" Katsuki hissed, making Kirishima snort. Katsuki simply rolled his eyes, linking their pinkies together as they walked. He was still a little awkward when trying to show affection, certainly in public, but Kirishima got the message. The red head quickly turned his hand, holding Katsuki's in his own. It caused a small pink blush to creep up Katsuki's face and he turned to look at the ground. Eijirou smiled, squeezing his hand as they walked out of the building together. They'd planned a squad outing today. Paintball to be exact. It promised to be fun and probably also a little painful, but fun nonetheless! They even made reservations and everything!

"There they are! Where were you blasty? Normally you're always so punctual" Sero commented.
"Had to kick Shinsou's ass" Katsuki shrugged.
"You're still doing that whole big bro thing with Eri?" Mina asked with a big smile.
"Awe! You're so cute sometimes blasty!"
"Shut up pinky! Let's get going before we're late" Bakugou grunted, ignoring their laughter and slight teasing as they made their way off campus.

Katsuki's presence in the group changed after everything that happened with his parents. He opened up more, started hanging out more often. They all became so much closer... It was something Katsuki never had before, but now that he knew what it was like he wasn't letting go. Yeah, these friends, this new family he found... They were irreplaceable. They almost made him forget al the shit he's been through to get here. Almost.
"Yeah, Kat has really been looking forward to this" Kirishima grinned, pulling Katsuki out of thought.

"What?"

"You said so yourself, right? That you couldn't wait to paintball with the squad?" Kirishima asked. He thought he remembered that right...
"Oh, yeah, I want to kill some bastards with guns" Katsuki simply answered.
"Dude, we're not killing anyone, it's paint" Kaminari snorted.
"Killing, winning, same thing" Katsuki shrugged.
"Ah yes, typical Kacchan fashion" Denki laughed.
